Floor damage catalog: here we provide a catalog of types of damage found to flooring in buildings, such as improper installation, buckling, burns, cracks, loose, sloped, squeaky floors, mechanical damage, wear damage, water damage, and special kinds of damage found on wood floors. We describe various causes of floor damage. We describe the wear and damage problems associated with different types of flooring materials such as carpeting, ceramic tile, vinyl or vinyl asbestos tile, resilient or sheet flooring, wood flooring.

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 (C) D FriedmanThe combination of broken cermaic 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 falll hazard, not be laid flat or torn, more trip hazards, or wet, rotted, and moldy, health hazards.

and CARPET STAIN DIAGNOSIS.

Also see CARPET MOLD CONTAMINATION for details.

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.

See FLOOR WOOD, DAMAGE DIAGNOSIS for examples and details.

 

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.

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

  • Burned resilient flooring under an overheating refrigerator compressor (vacuum the dust off of those coils!)
  • Cigarette burns on wood or resilient flooring.
  • Fireplace burns from heat or from coals or embers - possibly a fire hazard.

Cracked or Damaged Floor Tiles

MEthods for supporting tile flooring (C) Carson Dunlop AssociatesThe 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.

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

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.
