On 2017-05-05 by (mod) : Dog Girl of Brooklin explains how to get rid of dog odors that followed building contents moved to a new home
No surprise, Frank, but a point well made.
Pet odors, even worse from dogs or cats or iguanas peeing indoors, permeate porous materials: carpets, curtains, bedding, clothing, upholstered furniture that are then carried into the new home, so odors continue along too.
Even animal dust - dog dander - may be imported from an old building into the new one as belongings are moved without cleaning them enroute.
A previous girlfriend in Rhinebeck boarded sometimes more than a dozen dogs in her home for years. It was fun for the dogs who were brought up to the country by car from NY City. The dog girl was very clean, constantly cleaning her home.
But the dog smell was ... well ... strong. Remarkably, when I went even into remote places like the uppermost attic I came across deposits of thick dust brought indoors by the doggies who of course had been rolling about in the dust and dirt outdoors. That yellow-red-brown dog dust was an epidemic that will never be removed from the home without a gut renovation.
And that same dust might be found in the backs of bureau drawers and if I tested (vacuum test forensic sampling) uphostered furniture, it was full of the same material, even though the dog-girl vacuumed regularly with her household vacuum cleaner.
Use the search box just above to find our description of an easy SMELL PATCH TEST KIT that you can make-up to see if you can narrow down the worst smelling materials and then have those cleaned - or tossed out.
On 2017-05-05 by FrankI decided to move into a new place with my friend and while helping her pack up the old house it was easy to tell that her house smelled horrible. I assumed it was from the dogs urinating in the house. Well now that we have moved into the new place the same odor is now starting to linger into this house and dogs have been staying outside so what the hell is causing this smell I have literally been sick since I moved
On 2017-05-03 by (mod) re: dealing with odors blamed on the water softenerIf a water softener is a suspected odor source you'll want to keep it in bypass to see if that changes what you smell and where.
On 2017-05-03 by AnonymousHelp, smelly odor coming from my basement! I was wondering, after having my sump pump checked and my home inspected for mold, could this awful must smell be coming from a exiting water softener that is still hooked up but haven't been used for over 19 years? Could the stagnant water in the softener be causing this god awful smell? Could it be my air conditioner/heating system? I'm so tired of this awful smell when you enter my home!

So glad I found this site!! We have been dealing with a weirdness odor at my office for years. But it only seems to be in the winter. And when it it a cloudy foggy morning. We smell it the worst when we first get there and then it dissipates throughout the morning when the door is open.
We think it smells kinda like gas but they have come out and tested for gas and it's not that. Some days we can even taste it. The landlord has sent out a plumber but they have never found anything. Even the gas company has come out and they have never found a gas leak. We don't know what to do at this point. Help!

I just rented out a studio space (for painting only) at the bottom of a condo building. In the room next to me is a large oil tank from. A pipe from the oil tank goes through my unit before going outside. The room with the oil tank has no smell, however, my unit does. I think its coming from the oil pipe and the wall from which the pipe goes out through.
The super told me that the building switched from gas to oil, so the pipes have no oil going through however there could be residual oil in them etc.
I have gone up to the pipes and they smell and especially from the wall where the pipe is. Has oil leaked into wall? Can I cover this wall up with something to stop the smell. Any advice would be greatly appreciated

I'm sorry but we have no objective data describing dangerous chemical offgassing from washing machines.
Searching for scholarly research on washing machine offgassing finds research on IAQ questions raised by chemical perfumes used in some detergents and in clothes dryer sheets. It would be a shame to jump too quickly to an incorrect and perhaps expensive conclusion.

Help Help! I have smelled a sour smell upstairs for years. No one else smells it. It is mostly in a bedroom we seldom use and smells like sour smelly feet. My husband smells nothing at all. Years ago I thought it might be some of the antique furniture I have up there, but it is not. Sewer gas? N

On 2017-01-04 22:00:06.589812 by (mod) - odors coming through a shared party wall
We'd start with a visual inspection for obvious problem sources: leaks, mold, pets, stains.
If there is sufficient concern from external clues or building history or complaints, then I'd use a borescope or make a test cut into the wall at the most-suspect location to see what's in the wall cavity.
If there is an attic space above or crawl space below those areas should be inspected too.
Information about the nature of the odor can be diagnostic.
I would NOT rely on make-a-pound cute tools like light meters, moisture meters, gas detectors for a concern such as the one you raise.
Keep in mind that depending on where you live, a duet, or duplex as some people use the term, may require a fire-wall between adjoining units.

(Mar 7, 2014) April short said:
My installer and furnace salesman insist this 'rotten peach' odour has nothing to do with the furnace. On the web, many others have complained about it. The installer says the furnace works perfectly although when we bought it last year they installed it incorrectly and had to come back for an entire year and many service calls to get it right.
Now the rotten peach smell comes through all vents when the heat comes on. It is not present when the fan alone is on. It is not present when the furnace is off. It was not present when the old furnace was on.
I am getting nausea, dizziness and headaches. We have an oil furnace. They say I am imagining the odour even though one installer could smell it. I can use any help I can get. We have had extra air returns put in, a new condensation mat- anything the installer could think of to no avail. I am home all day and getting ill from the fumes.
April, there is just not enough information in this text exchange to allow speculation on the odor source you describe; what's needed is an onsite expert to assist you. It may be helpful however to keep a log of odor observations and time of day and relationship to equipment being on or off.
I've suggested elsewhere that especially with warm air heat (you describe a "furnace" that's a warm air system) odors can be transported in ductwork from one building are a to another.
For safety be sure you have working, properly located and installed smoke detectors and carbon monoxide detectors.

We have a strong 'industrial cleaner' odor in our entry hall way. 3 level home, the odor is on 1st floor, ground level. The smell almost seems as
'pen marker' smell, or glue. We are unable to figure out where its coming from. The smell was in the garage as well, but now almost gone.
Our right next door neighbor seem to have the same strong smell, but in her garage. What company would be able to identify what is going on?
They have done no paint or other jobs inside the home.
Michael I'm not sure what company, among those who would claim they could solve your problem, could actually do so reliably and economically, especially if the only approach is to apply more chemicals in form of a "dedodorant".
Usually it's best to track down the smell to its probable source using someone coming up from fresh air away from the site and who has a good sense of smell, combined with visual inspection for likely odor sources. Sometimes our SMELL PATCH TEST KIT approach (very inexpensive) can help.
If you call industrial hygienists, IAQ consultants, or home inspectors who offer the service discuss their experince and their approach. I would not hire someone who's just going to stop by and "do some tests" without a thorough inspection.

(June 25, 2014) Arlene said:
I live in a high rise building (more than 30 floors). Since February, there has been an odor in the hallway outside my neighbor's apartment and now also outside my apartment and sometimes coming into my apartment.
Others smell this, too. But I seem to be the only one having a reaction (I can feel it on my tongue and in my stomach).
The building did a test for organic compounds (unfortunately when I was away). I have the "negative" results, and the building intends to do nothing else.
The smell is intermittent. Sometimes it is as if it was never there. Sometimes it is weak. Sometimes very strong. People think it is a chemical odor; some think it seems like strong cleaning materials. The building management denies any responsibility for the odor.
There were 2 times that wallboard was breached in repairs since I moved in over 2 years ago: (1) to deal with some leak that was not in my apartment but apparently originated within a chase in my apartment that caused a leak of a fresh water pipe in the storage room; (2) repairs in the ceiling outside my apartment; I am unsure what was fixed. I cannot tie the origin to either repair but cannot rule them out. My understanding is that it is possible that the repairs breached fire stops that were not repaired.
I do not know what to do next. The smell makes me feel ill. I cannot figure out what we are smelling or what the path to my area of the building might be.
Unfortunately, doing a "test for organic compounds" may have been a bit of an unreliable shot in the dark, as the chemistry of gases and odors can be complex so that choosing a rather specific test may not give an assurance that "nothing is present".
Keeping an odor log that relates smells to various changing factors such as weather, occupancy, operation of equipment, and using a smell patch test approach can usually narrow down the source.
Keep in mind that elevator shafts, stairwells, HVAC systems, vent systems and other mechanical means can transport odors in tall buildings.

My septic tank had overfilled. the plug was not in the bathroom sink. I have a brown stain on the glass shower doors. does anyone know how to clean this off? I have tried TSP, bleach, Mr Clean...with no success - thank you
Watch out: because health hazards are involved, sewage backups are cleaned using household cleaners and disinfectants. If a large area of was contaminated you probably should hire a professional.
A single sewage backup would not in my experience make permanent stains on a glass shower door, but perhaps there was a pre-existing mineral deposit that resists cleaning. In that case you need a cleaner that removes mineral scale deposits or iron deposits - readily found at your supermarket or building supplier in the cleaner section. Sometimes even vinegar will do the trick.

I have lived in my home for ten years. About five years ago I used a cleaning service that used bleach to clean my bathrooms. About three days after the cleaning, I would smell a scent that smelled like body order to me. This continued even after I no longer used the cleaning service. It has become worse over the years.
I have a glass tile window above the bath tub with vinyl shutters over. it. The window faces west and it seams that the heat causes the fumes to come either from the window or the shutters.
I wonder if cleaning either of these with bleach could remove a protective coating or cause a chemical reaction with the heat causing the smell of (body order to me) or a hot chemical smell (to my husband).
Can anyone give me any information about this condition?
In the More Reading links just above please click on the article titled
PLASTIC ODORS-SCREENS, SIDING
to read about the odor source you suspect.
let me know if questions remain
There is a strong odor of what I believe to be gasoline coming from my outdoor shower. The previous owner had a motorcycle he kept in the vicinity. What can I clean it with? The shower water drains onto a wood floor and out into the dirt below.
First we need to know accurately where this odor comes from: a spill, adjacent equipment, or (dangerously) in the water supply itself. For surfaces you can try the SMELL PATCH TEST KIT we recommend above - easy and nearly free.
If gasoline or other petroleum product spills occurred onto nearby soils the soil may need to be removed or encapsulated.

Watch out: be sure that you have working carbon monoxide and smoke detectors properly located and installed.
If your alarms sound go outside and call your emergency services.
If you are sure the odor is coming from your heating system you should call a heating service company promptly.

TCP is a mild antiseptic used in the E.U. and produced by a French company. Sold in the U.K. by Omega Pharma. If you are pretty sure that's the odor I'd talk to the cleaners or see if a neighbour spilled the antiseptic nearby.

We get an intermittent smell in our ensuite. It is a musty smell rather than sewage. It is strongest when the wind is blowing outside and often is not detected for days at a time. We have decide to replace the toilet and my husband removed the toilet and placed a plastic bag over the end of the waste pipe.
Surprisingly this is moving as if a breeze is blowing up the pipe. The downpipe enters the sewage system through the garden and we can see no possible way a wind is entering the pipe.
Nice detective work S.D.
It's quite plausible that depending on building shape, roof shape, location of plumbing vents and other factors we might on occasion see a temporary downdraft down a plumbing vent stack.
There may also be natural downdrafts that occur in a vent stack when a volume of water is sent flowing down a drain.
That is how the vent should be working. By allowing air into the plumbing vent system to satisfy the vacuum created by emptying a plumbing sink tub, or toilet, we are preventing the siphonage of water out of nearby plumbing traps. We need to keep water in the traps to avoid smelly and potentially explosive sewer gases from entering the building from its drain system.
As long as we have not siphoned water out of a trap and as long as there are no leaks in drains nor in the vent piping system we should not smell sewer odors in a building. If we do we look, as you are, for a leaky toilet seal, lost water seals in traps (check floor drains), or a leak in the vent piping system.
Other "musty" odors might be traced to leaks or mold too.

I live in the northeast US in an apartment in a large house hat has several other apartments. The house is over 100 years old and may be 150 years old. There has been for the last few years a "heavy" musty smell in the air. This smell also smells up my clothing. I notice it if I spend a few nights away. When I return it beomes barely noticeable after about a day. The building manger says it's not mold but I don't think they really know what it is. They said it is "old house smell".
Find where the odor is strongest
Keep in mind that old house musty odors are also often related to inadequate ventilation - and can be part of an IAQ issue that can in turn be a health hazard to some occupants.
(Nov 30, 2015) Lis said:
Thank you for your prompt reply. The smell is everywhere in my apartment and probably through the house. It is "musty" with a tinge of ammonia smell. It almost seems to be like an invisible cloud with higher concentrations higher in the air. There have been numerous water leaks in pipes in the walls over the years but a plumber fixed these when they happened. Could the smell just be "old house smell"? Does this even exist or is it definitely something else?
Even when smell is everywhere usually someone with a good sense of smell, coming in from fresh outdoor air, can determine where the odor is strongest. I'd try that; otherwise we're shooting in the dark.
A second direction of investigation is to look at leaks that occurred any time in the past; follow the water - what got wet; a wet wall or ceiling cavity or insulation could harbor a mold colony.
(Nov 30, 2015) Lis said:
Thank you again for your prompt reply. The smell is EVERYWHERE equally in the apartment. I have a good sense of smell. The best way I can describe it, when I have been away for at least a day, is a pungent "musty" small with a very slight burring sensation when breathed in through my nose; almost like ammonia.
As I indicated below the building manger says it's just "old house smell" (the house is at least 100 years old). My question is: Is there such a thing as "old house smell", like wood and materials that have simply decayed over the many years? Do you think it is mold?
Yes old houses often have a characteristic odor. However the odor has a source; it's not generic.
Common sources include bat or rodent fecal or urine waste in walls or ceilings, food or cooking or cigarette deposits on surfaces, prior spills, puffbacks, events. A combination of removal, cleaning, and sealing can correct the trouble but the task can be arduous.
For example in a home in Rhinebeck NY the owner boarded dogs in her home for a decade or more. Dog odor was everywhere. Inspecting in the attic and wall cavities I found ultra-fine dust comprised of dog dander and dirt brought inside by the doggies when they came in from romping in the yard and rolling in the dirt.
To clean such an area would involve removing porous materials that can't be economically cleaned (insulation in this case), HEPA vacuuming, perhaps washing damp wiping, and perhaps applying a post-fire odor-sealant before re-insulating.
In your case cleaning and removal of old materials such as carpets or curtains and re-painting old surfaces can reduce much of the odor you describe.
Still it would be a fundamental error to fail to look for specific problems such as leaks, rodents, spills.
"Decayed wood" indoors such as at trim and furniture is not likely unless there has been flooding or extensive leakage and would thus not be the source of your complaint.
(Dec 1, 2015) Lis said:
Thank you again. What kind of company should I contact who will be able to accurately identify the source and correct it? Are there any national companies that do this? Do any companies give a free evaluation?
At the top of any of our pages you'll find some links to EXPERTS DIRECTORIES that include environmental investigators.
I'm doubtful someone could possibly give a free evaluation for a whole house survey for a source of a non-specific odor.
Beware of mere "testing" - vs inspecting - there is no generic single test that can identify all possible contaminants in a building and even if you did find out by testing what the dominant chemicals are, that may not tell you where the odor source is originating.

I own a large block of shops and the dress shop is complaining about a bad smell from the Chinese Takeaway shop next door.
They are situated on a hill,the takeaway is slightly higher and much longer so is also behind the dress shop.
I have checked the plumbing and sewer and can find nothing, plus food and fat disposal appears to be done correctly.
Could their fan system above the fryers be the problem?
It can be difficult to control cooking odors between two abutting spaces, but you may be able to improve life (and business) for the dress shop with help from an HVAC engineer familiar with the issues. Improvements to the Chinese Takeaway's exhaust venting might need to be supplemented by putting the dress shop under positive pressure, blowing in fresh air ducted from a not-smelly source.
But first I'd check to see if there are obvious snafus that can simply be fixed, such as a vent fan drawing odors into the dress shop, or odors and air passing via a suspended ceiling, open fire door, ductwork, etc.
Watch out: if the Chinese Takeaway's kitchen is not properly vented and/or lacks proper fire prevention systems there may be building fire hazards as well.

My daughter moved into an apt. last Nov. It was next to an elevator. In her front closet were some pipes running up and through. She slowly found more and more of a fume in her place, like burnt rubber from the elevator and sometimes peppery. Only in her place. we checked for everything, ruled out meth lab, gas leak,etc.
So bad one nite I said get to the ER and then to a hotel and tomorrow your moving.
Her blood test was so bad the MD said in 24hrs she wouldve DIED! The fumes were coming from her hair and skin. I wanted her to leave the couch and mattress but we arent that rich and she did move them. and the rug. A week later the smell was coming from them and we threw them out and she is sleeping on the floor.
She washed everything 12x with baking soda, tide extra and vinegar rinse water. Only the bedroom smells a little better and her books shoes and coats are still in double sealed bags. What could this be. Help!
Lisa what you describe sounds serious but there is no information that would let us make a diagnostic nor repair suggestion; your daughter and the building owner need an on site expert.
"Blood levels" of what?
"Fumes" of what?
Watch out: Baking soda and vinegar won't correct building contaminants nor any other unsafe or un-healthy indoor air quality issue.
(May 31, 2016) Lisa said:
Thank you for the comment, I now have more info and maybe you can help us to get rid of the oder.
The MD said she had CO2 poisening from the fumes. The landlord owns dozens of blds in DC an knows nothing.No onsite expert was possible, just an air quality test cost thousands and she has to go thru foiAct to get info on bldg maintenance.
She tracked it down to the elevator next to her venting into the closet.It has hydrolic oil that lubricates the cable and when it gets low the friction is what poured the vapor into the elevator and the hole in her front closet. The smell came and went in strengh as the elev. was oiled, I guess.
She had so much co2in her blood she was almost a fatality. what about the next young person to move in there as they were very cavalier about it.
But our question is, this poor kid has had to toss out our double bag and store everything she owns...what can she do to remove the oder which keeps coming back in the new apt.IS there anything that can help her salvage her school books, clothes etc.from this rotting burnt rubber smell? Thanks
Sorry for the delay in posting your comment, Lisa; the Comments software sees a period not followed by a space as perhaps an illegal web link and blocks the comment until I see it.
CO poisoning effects, unless caught quickly, can be missed in a person. I agree that that is an extremely-serious life-hazard.
The question is where the CO came from. Throwing away clothes has nothing to do with CO poisoning; CO in buildings is typically produced by heating equipment that lacks adequate combustion air, or on occasion by gasoline engines running indoors such as in a parking garage.
A top priority from what you said is, in my OPINION, that no one should be in that building without properly-installed, properly-located, tested, working CO and smoke detectors, and further that if you are sure the CO exposure problem occurred in the building, not elsewhere, building management needs to be notified immediately, in writing and orally, as there may be very urgent life-safety issues.
Watch out: On any evidence of a current CO hazard the building is not safe to occupy and it may be appropriate to call emergency services - 911.
CO itself is odorless, but the gases containing CO may have an odor that suggests their origin, such as from a heating system or a parking garage.
In a building with stairways and elevator shafts air is moved up and down (for example by the elevator) so can be moved between building floors, transporting odors or even dangerous gases from one place to another.
See the article series beginning at CARBON MONOXIDE - CO
You can better guess at what other hazards may accompany the "burnt rubber" smell by tracing the smell to its origin; I can't guess at what it is by e-text.
