  Excerpt:
  Preservation is defined as “the act or process of applying measures necessary to sustain the existing form, integrity, and materials of an historic property.
  
  Work, including preliminary measures to protect and stabilize the property, generally focuses upon the ongoing maintenance and repair of historic materials and features rather than extensive replacement and new construction.” (Chambers 1976)
  
  Maintenance helps preserve the integrity of historic structures. If existing materials are regularly maintained and deterioration is significantly reduced or prevented, the integrity of materials and workmanship of the building is protected.
  
  Proper maintenance is the most cost effective method of extending the life of a building. As soon as a building is constructed, restored, or rehabilitated, physical care is needed to slow the natural process of deterioration.
  
  An older building has already experienced years of normal weathering and may have suffered from neglect or inappropriate work as well.

  Excerpts:
  Serpentine stone was frequently used as a building material in the late 19th century because of its distinctive greenish color.
  
  Numerous residential and moderate-scale institutional buildings were constructed using serpentine for entire facades or simply as a trim material in urban areas such as Philadelphia, New York, Washington, Baltimore and Chicago, as well as in rural areas close to the quarries such as Chester County, Pennsylvania, and northern Maryland.
  
  However, serpentine's popularity was short-lived because of its fragility. Serpentine is a soft stone composed primarily of hydrous magnesium silicate which is basically the same mineral found in talc.
  
  It is not tightly consolidated, but a fibrous material that tends to absorb water. The presence of water accelerates the deterioration of the stone due to the effects of the expansion and contraction of the stone during freeze/thaw cycles.
  
  Since serpentine is an alkaline stone, it is also sensitive to attacks from sulphuric and sulphurous acids, and carbon dioxide dissolved in rainwater.

Synthetic Stucco, EIFS Siding Products, Failures, Litigation, Services

EIFS is an abbreviation for "Exterior Insulation and Finish Systems" or "barrier", a synthetic stucco material which is usually applied over a system of solid foam insulation board and synthetic fabrics to form a stucco building exterior surface.

There have been substantial building failures and costly damage at many EIFS covered buildings, primarily because the EIFS-covered building exterior may leak into the building walls but the foam insulation used beneath this stucco method may not allow moisture to escape from building cavities.

See SIDING EIFS & STUCCO for details about this topic.

Readers should also see STUCCO OVER FOAM INSULATION.

Yes, at least some areas may need replacement. IF there are water leaks into its walls .

On 2022-09-05 by InspectApedia-911 (mod) - home inspection needed before buying a house

@Aslam,

When you are ready to make an offer or have made one, "subject to buyer's approval of the results of a professional home inspection ", then have an inspection performed.

On 2022-09-05 by Aslam

@InspectApedia-911, I am looking at 50+ houses; how would I get an inspection done on 50 houses? It would cost way too much. I am trying to narrow down my options before proceeding with 2-4 houses.

On 2022-09-05 by InspectApedia-911 (mod)

@Anonymous,

Yes but ... you should not proceed to buy a home without a complete home inspection, covering ALL topics, performed by an independent home inspector who has no conflict of interest (such as recommendations by the real estate agent).

Else you have no idea of what work is needed nor in what order.

With that information you can decide what topics need an actual repair cost estimate so that you have a more-accurate understanding of the actual cost of the home.

On 2022-09-04 by Aslam

@InspectApedia , I am a new home buyer. Can I just contact the seller's agent and ask them whether I can send an inspector to the house? Or should I accompany the inspector? I have never done inspections on the house before, if you can shed some light, that would be awesome.

On 2022-09-04 by InspectApedia (mod) - repair estimates depend on results of home inspection

@Aslam,

From one photo, it is impossible for anyone to give you an estimate on the repair costs for this home, both in general and for those specific areas you've circled.

Without a thorough onsite inspection, there is no way to know what may be involved, both interior and exterior, including potential water leaks, rotting wood, roof issues, ventilation and insulation concerns, wiring and plumbing upgrades, among many potential areas of need.

For example, we don't know whether that entry deck is completely rotted and needs to be replaced or whether it's simply needs minor repairs.

In addition, the costs of materials and labor can vary greatly based on the location of the home, so again, impossible to estimate from a picture alone. It generally costs more to make repairs that are high off the ground such as that upper roof edges because one has to work from ladders and scaffolds.

A very thorough onsite inspection of the home is needed in order to assess the damages and then seek estimates from local professionals to get the potential range of repair costs.

You need to set priorities for the repairs. Things that are causing rapid expensive damage, that are unsafe, or that flat don't work reliably are your top priorities.

In order to absolutely assure our readers that we write and report without bias we do not sell any products nor services, nor do we have any business or financial relationships that could create such conflicts of interest.

How much would it cost to repair the exterior of this house (Attached image)? What type of repair would it need? I am trying to bring the house in decent condition.

On 2021-09-29 by inspectapedia.com.moderator

@Jesse Bridges,

There isn't one single structure for that purpose, and not all buildings have rain protection of the front entry.

Perhaps you're referring to an entry porch and entry porch roof.

On 2021-09-28 by Jesse Bridges

What is the name of the structure that protects your from the rain as you go into the house? It's an A framed structure - part of a 2 family unit

On 2021-09-07 by inspectapedia.com.moderator (mod) - leaks because siding was not installed correctly

@Matthew G,

Your private inspector is suggesting spending thousands of times more in a proposal that may not be necessary.

Certainly if there's a leak at the bottom of siding, it seems questionable that you would need to remove all the siding from a building. That's the kind of advice that's tempting when you're spending somebody else's money and not your own.

What I mean to say is that it's really worth getting an accurate diagnosis of the problem before we start throwing money at it.

It doesn't sound very precise to simply say there's a leak, pull all the siding off.

On 2021-09-07 by Matthew G

I have LP Smartsiding that was not installed correctly, doesn't overhang foundation enough, and now we have leaks in 2 rooms. House was built in 2021 and the builder can't find the source of the leak. They're proposing cutting off 5 inches around entire house, installing flashing and a trim board along bottom of house. Our private inspector recommends removing it all and installing correctly instead of bandaid fix from builder. Thoughts?

On 2020-10-12 by danjoefriedman (mod) - best adhesive for covering glass block

I think the answer depends in part on how large is the glass block area to be covered. If it were a smaller area, I might use a mortar or stucco mix

On 2020-10-11 by AlexEnergy5

What is the best adhesive for covering glass block on the exterior with aluminum sheathing? Is there another better way to cover glass block on the outside of a house (other than 2 coats of good quality paint) ?

On 2020-08-11 6 - by (mod) - Hardieplank is buckling

Barry

Thank you for your generous comments.

Often buckling is from improper nailing (too-tightly butted siding sections against vertical obstructions for example) combined with moisture uptake, but absent a site investigation that's mere speculation.

You might find a suitable onsite inspector who is familiar with Hardieplank and who can document the situation clearly by checking among the inspectors in our page top EXPERTS DIRECTORY.

Sorry I'm not available for field work - retired and quarantined from COVID-19

but if specific reports are available or technical questions arise, I'll be glad to offer limited pro bono assistance as we may both learn something.

On 2020-08-10 by Barry Schenof

I'm a real estate lawyer in Washington, DC (who happened to study architecture for a year). A long-time client owns a shopping center in nearby Virginia. Recently, a large portion their exterior was reclad in Hardieplank. The job was finished in February 2020. There are now portions of the boards that are waiving.

We are looking for someone to advise about what is a practical fix. There are more details I can provide by phone or otherwise. Would you be available to assist or can you recommend someone else? Your expertise is jaw-dropping along with your unselfishness in sharing it with the public. Barry Schenof 202-316-0200

On 2020-05-10 - by (mod) -

I'd start by a careful inspection outside to look for a leak source.

That tear-drop shape and tan color suggest a leak from above in just that location.

On 2020-05-10 by zogos@outlook.com

Hi
Hope you can help. I attached a photo of one of the stains on our rendered wall. There's a few more of these. How do I deal with them? look forward to your reply. Cheers

On 2020-03-2 - by (mod) - 1952 Massachusetts home has fiber board exterior sheathing

Mike:

What kind of fiberboard?

Fiber cement board can be very durable while all-wood-product fiberboard is not durable, particularly close to ground where it is subject to rain splash-up or in other locations where, believe it or not, it gets wet.

What was the original siding on your 1952 MA home?

See FIBERBOARD SHEATHING IDENTIFICATION

Looking at a house built in 1952 in Massachusetts, which has fiber board exterior sheathing. Was this a good option in 1952? Is it likely still viable as is?

On 2019-11-23 - by (mod) - front threshold landing level with interior floor

What your local code inspector requires may vary by country and city and jurisdiction. However is quite common for the walking surface of the landing to be the same as the walking surface of the interior floor. Typically the door threshold is slightly above that level.

Where there's a concern for water entry or for snowfall blocking the ability to exit door where a storm door or main door swings out, the local inspector may permit a step down but that's generally not the case. If you could attach a photo that would be helpful

On 2019-11-23 by Frog

We have a brand new cement landing for the front door of our house. The cement was poured right up to the door threshold and now we can't replace the old door with a new one because of how the cement was poured.

Also given that the cement is right up to the threshold there is also a fear that when it rains that water will come in thru the front door since its threshold is level with the cement. Is there some general specs that outline how many inches below the door threshold the cement should be poured or some best practice?
