Application Errors, Carpeting, Tile, Vinyl Tile, Resilient or Sheet Linoleum or Vinyl or Wood Floors

Some ceramic tiles are intended for wall use only. When used on floors, they will wear quickly.

Ceramic tiles and softer clay or terracotta floor tiles are also broken, forming cut and trip hazards such as this floor (photo at left) we photographed in Barcelona, Spain.

Stained loose carpet on stairs © D Friedman at InspectApedia.com

The combination of broken ceramic tile risers and stair treads and a dark hallway are an invitation to a slip trip or fall accident in this building.

Carpet may be loose on stairs, a serious trip and fall hazard, not be laid flat or torn, more trip hazards, or wet, rotted, and moldy, health hazards.

See CARPET STAIN DIAGNOSIS.

Wood flooring may not be well secured, buckled, rotted, due to improper installation or lack of maintenance, or failure to act immediately following a spill or leak in the building.

Damaged Asbestos-Containing Floor Tiles, Sheet Flooring, Carpet Padding

Vinyl and vinyl asbestos tile floors and other resilient flooring such as linoleum or sheet vinyl may form trip hazards at tears and bulges or just plain disintegrate; some products contain asbestos and must be handled appropriately.

Tile and stone flooring may not be set properly or may be installed over inadequately stiff framing (leading to cracking). Grout may be poor quality or an incorrect type.

Buckling Wood or Wood Laminate Flooring

Improper floor installation can conspire with shifts in building moisture (or outright leaks) and temperature to cause severe buckling of wood floors and in some instances laminate flooring products as well.

Also failure to install a properly level and smooth underlayment or subfloor can cause uneven laminate floor surfaces.

Burn Marks on Flooring

Most types of flooring are susceptible to burns, with the exception of stone, terrazzo, ceramic and quarry tile. Common burns on finish flooring that we find include

Cracked or Damaged Floor Tiles

MEthods for supporting tile flooring (C) Carson Dunlop Associates

The most common problem with brittle floor tiles is cracking. This is usually the result of a floor system that is not stiff enough to support the tile. Tiles can also be cracked by impact damage. Heavy items dropped on the tiles will sometimes crack or break them. Replacing individual tiles is not difficult, although color and grout matching may be a problem.

A cracked and broken concrete floor may only be a problem if it is not safe to walk across, or if there is moisture coming up through the floor. Since it is not a structural component, replacement of this floor is rarely a priority item.

Loose Flooring & Trip Hazards

Loose or missing sections of flooring should be replaced.

These areas may present a trip hazard. Carpet with ridges and buckles can be pulled tight to lie flat again by a carpet installer.

Sloped Floors out of Level

A concrete basement or crawl space floor that does not slope down to a floor drain can lead to water accumulation on the floor and resulting damage. Adding more concrete to an existing slab to improve the drainage slope is difficult, since new concrete does not usually bond well to old concrete.

A better solution may be to add another floor drain. This is expensive, because it requires breaking up some of the concrete floor. Replacing a deteriorated floor may be more cost effective than trying to repair or re-slope the floor.

Squeaky Noisy Floors

Squeaky wood floors are a nuisance, not a structural problem. A floor usually squeaks when walked on because the flooring finish or subfloor is not tightly secured. The subfloor may not be well-secured to the joists, or the finished flooring material (e.g. hardwood) may not be tightly fastened to the subfloor.

Flooring that is not tightly secured sits just above the support in some spots. When someone steps on the flooring in this area, it is pushed down onto its support. When the foot is taken off the floor, it springs back up. The squeaking is usually the result of the nails sliding in and out of the nail holes, or adjacent wood surfaces rubbing.

See SOUND CONTROL for FLOORS

Mechanical Damage & Wear on Floor Finishes

When softwoods such as pine, fir or cedar are used as finish floorings, they can be damaged by high heeled shoes, for example. Furniture marking and denting is another common problem with softwood and resilient floors.

Softer materials, such as resilient flooring and carpet, will eventually wear out in high traffic areas. Sharp objects and furniture dropped or dragged across flooring may also damage the surface.

At FLOOR WOOD, DAMAGE DIAGNOSIS we discuss mechanical damage to flooring.

Water Damage or Stains on Floors

Common sources of water Damage/ damage include leaks from roofs, windows, doors and skylights, plumbing leaks (especially toilets and showers), leaks from hot water heating systems, and condensation.

At left the floor was damaged by pet urine, then re-finished or re-coated without removing the stains.

Aquariums, room humidifiers or dehumidifiers, over-watering of plants, melting snow and ice from boots, etc. can all cause water damage.

Wood-based floors may discolor, cup, buckle, warp or rot as a result of exposure to water. Carpet may develop mold. Flooring may be stained by water, food spills, improper cleaning, dirt, sunlight, or other factors.

On 2022-01-30 by Inspectapedia Com Moderator - kitchen flooring laid off center

@Dave,

This sounds like an installation aesthetics topic unless you're telling me that the floor is actually damaged in some way.

If that were my floor and I were concerned that it didn't seem to align correctly with the walls, I would make some careful measurements first to see whether or not the room is out of square.

Quite obviously if the room is not square then the flooring cannot align perfectly with all of the walls.

On 2022-01-29 by Dave

Our engineered floor has been laid off centre. Is there any tolerances on this as the difference is 35mm from one end of the kitchen to the other over a 5 metre kitchen. The entire floor has been laid about 10 degrees off centre.

On 2021-10-22 by inspectapedia.com.moderator - how can I change the wrong color putty used to fill screw holes?

@R Jones,

Try carefully drilling out the mismatched putty and test some that is the right color

On 2021-10-22 by R Jones

Supposed carpenter said he could get rid of squeaks in our hardwood flooring. He's done work for us before so we trusted him. He used a ton of "Squeak No More screws about an inch to inch and 1/2 apart in the seam spaces between the boards then filled to holes with a putty too light in color.

Will those whole areas have to be pulled up and replaced as I assume there is no way to get those screws out after the tops are broken off?

On 2021-07-28 by inspectapedia.com.moderator - use moisture meter to investigate floor moisture problem

@Gianni,

The photo is not quite sharp enough for me to be sure, but in trying to zoom in on your images it looks to me as if there may be a moisture problem under this floor, and you may be seeing the result of that as damaged flooring or even a fluorescence seeping up at joints.

You could try doing some investigating with a moisture meter, and you could also investigate the history of any spills on to or water entry below the flooring.

We installed smart core wood laminate flooring and noticed that in high traffic areas the floor look bad and the creases look bad. Looking forward some assistance

@Cami,

Let's start with a point of clarification. If this is a vinyl floor then it's surface isn't painted but it may indeed have a very thin vinyl skin that imparts the color and texture.

In diagnosing the color or material loss that you mention I would look for the wear pattern to see if it's related to foot traffic and raised areas in the flooring and I would look at it under magnification to see exactly how the material has come off.

While this is by no means an authoritative opinion I would bet that the manufacturer will consider your complaint to be normal wear and tear. And it may be normal for their product.

On 2021-06-03 by Cami

I had lifetime vinyl flooring installed in December. It is Dynamic Hardcore 3DGE Shoal and the painted beveled edge is flaking up and trying to find out what is causing it. Personally I think it’s a defect in the painted edge and trying to find out if this is a common issue with this type of floor.

On 2021-03-09 by danjoefriedman (mod) - smaller visible termite damage may indicate much more extensive damage

@PHO,
You can be certain that if the termite damage is bad enough to come up through the finished surface of the floor, there is a good chance that it is long standing and quite extensive.

IF the building was successfully treated for wood destroying insects, then yes, they may not be active; but there is likely to be substantial hidden damage.

On 2021-03-08 by PHO

Pls see pics. Inspector said termites? Only 3 spots in whole floor and this is by far the worst.... others are just minor slits in wood. These have been in wood for awhile and havent gotten worse.

Gaps and ridges in Amitco Spacia flooring (C) InspectApedia.com ChrisChris:

Thank you for the helpful question about LVF flooring gaps and ridges: cause and (not so likely) cure.

I've seen this gap and ridge problem on most types of manufactured as well as other types of wood and plank and vinyl or engineered flooring, caused usually by temperature and humidity changes and occasionally by installation errors such as failure to leave a bit of space around the floor perimeter.

Let's compare the manufacturer's flooring installation instructions with what you know about your floor's installation to see if we can be more-specific. All of the warnings given below, excerpted from the Amitco Spacia installation instructions warn of conditions that might cause the gaps or ridge that you mention.

Take a look at the AMITCO SPACIA FLOORING INSTALLATION INSTRUCTIONS [PDF]

Here are a couple of examples to consider:

Mannington LVF flooring should remain at a temperature between 55°-85° F (13°-29° C) during its service life.

MATERIAL RECEIVING, HANDLING & STORAGE

1. All floor covering products require care during storage and handling. It is important to store flooring products in a dry, temperature-controlled interior area.

2. The temperature range should be between 65º F and 100º F, and the relative humidity should be controlled and maintained between 30% to 70%.

3. Material must be conditioned for at least 48 hours before beginning the installation.

4. Flooring materials that are shipped in cartons must also be stored properly. Cartons must be kept squarely positioned on the pallet to prevent distortion of the contents and to be fully supported. Do not store close to exterior walls, in direct sunlight or near HVAC vents

and

1. Before jobsite testing, the building envelope must be sealed (walls, roofing, windows, doorways etc., installed).

2. The installation area and materials to be installed shall be maintained at a minimum of 65°F (18.3°C) and a maximum of 85°F (29.4°C) for 48 hours before, during and for 48 hours after completion of the installation. Relative humidity level extremes should also be avoided.

General recommended humidity control level is between 35 – 55 %.

If a system other than the permanent HVAC source is utilized, it must provide proper control of both temperature and humidity to recommended or specific levels for the appropriate time duration.

Picture [above]

I have had an Amtico spacia fitted in a kitchen diner. Gaps have appeared between the plants some credit card size . A small ridge exists in the floor where the wall was removed. This has made the floor not level for a small part.

I'd check different areas of the flooring that have or have not been treated with the cleaners you've tried and for moisture level. If the floor surface was damaged by a cleaner containing a solvent, the resulting gummy top surface may not recover very well.

On 2016-08-28 by Nona

I have a newer vinyl floor. Not even 5 years old. I can't figure out why it has become sticky. We have air conditioners to help with humidity. And I mop the floor regularly. But even right after mopping the floor is sticky. Any ideas. I am used get an all purpose cleaner in water. I have also rinsed it with straight water.
