Can you install or refinish your own floors, or should you hire a pro?

Can you do your own flooring?

Some of it, safely. Clearing rooms, routine care and some prep are well within a homeowner's reach. Sanding a wood floor, tearing out old resilient flooring and working in a house built before 1978 are where the federal agencies' warnings pile up. Carpet and tile both have trade bodies that recommend trained installers, for reasons they spell out.

What can a homeowner reasonably do?

Routine care. The National Wood Flooring Association (NWFA), the hardwood trade's association, says routine cleaning is sweeping, dust mopping or vacuuming on the bare-floor setting, with spills wiped up at once. It warns against wet mops and steam mops, which it says damage the finish and the wood over time.
Getting ready for the installer. The Carpet and Rug Institute (CRI), the carpet industry's association, lists jobs a homeowner can sort out beforehand: moving breakables out, detaching electronics, finishing any painting or wallpapering first and agreeing who moves furniture and who takes away the old carpet and cushion. It also suggests vacuuming the old floor before it comes up, to cut airborne dust.
Inspecting the material. The CRI says to check new carpet for visible defects before it goes down. The Ceramic Tile Education Foundation (CTEF), a tile industry education body, says to look at several pieces of tile and be wary of choosing from an online image, since shade can vary a great deal from tile to tile.

Why is sanding a wood floor a job for a professional?

Because of the dust and the vapors, before skill even comes into it.

Wood dust. The Occupational Safety and Health Administration (OSHA) says wood dust becomes a potential health problem when particles from sanding and cutting become airborne, and that breathing them may cause allergic and other respiratory symptoms and cancer. It adds that the extent of these hazards, and which woods are involved, have not been clearly established.
Finish vapors. The U.S. Environmental Protection Agency (EPA) says varnishes and waxes contain organic solvents, that such compounds can cause eye, nose and throat irritation, headaches and nausea, and that indoor levels can stay high long after the work is done. It advises meeting or exceeding the label's precautions and, if a label says to use a product in a well-ventilated area, working outdoors or with an exhaust fan or open windows.
Fire. Investigators in Massachusetts traced a house fire to oil-based staining rags left overnight in a five-gallon bucket. The local fire chief said the oils give off heat as they dry and that rags should be left to dry individually outdoors, away from anything combustible.

Cutting stone tile or a concrete slab carries a dust risk too. OSHA says respirable crystalline silica is created when stone, concrete, brick and mortar are cut, ground or drilled, and that workers who breathe it are at increased risk of an incurable lung disease, lung cancer and kidney disease.

What should you never do to old vinyl flooring?

The EPA is direct about flooring that may contain asbestos, which it says can include vinyl floor tiles, sheet flooring backing and adhesives:

Do not sand it, or try to level it or its backing.
Do not use a power stripper on it, or abrasive pads or brushes to strip wax.
Do not dust, sweep or vacuum debris that may contain asbestos.
Do not take samples yourself. The EPA says sampling done incorrectly can be more hazardous than leaving the material alone.

Its preferred answer for worn asbestos flooring is to install new flooring over it if possible. Removal, where needed, should be done only by a trained and accredited professional; the EPA says improper removal may increase your family's exposure.

What if the house was built before 1978?

The EPA's lead rule does not generally apply to homeowners working on their own homes. It does apply if you rent out all or part of the home, run a child care center in it, or buy, renovate and sell houses. Even when the rule does not apply, the EPA recommends hiring a lead-safe certified contractor, and says a homeowner who goes ahead should use its do-it-yourself lead-safe practices: find out the home's age or assume lead is present, seal the work area with plastic, turn off forced-air heating and cooling and cover vents, wear a disposable N-100 respirator, and mist surfaces before sanding to keep dust down.

Its main concern is children. The EPA says young children who crawl and play on floors and put things in their mouths are most at risk from lead dust, and that even a small amount of dust from a project can pose risks.

Why do the carpet and tile trades say to hire installers?

The CRI calls carpet installation "a job for the professionals" and points to its installation standard, which requires carpet to be power-stretched and seams sealed. The CTEF says a quality tile job depends on a flat and rigid base, at least 80 percent mortar coverage under each tile in dry areas and 95 percent in wet ones, movement joints and proper cure time. Those are claims made by the industries concerned, but they describe the checks a homeowner would have to meet working alone.

Do Pennsylvania's rules change if you do it yourself?

The Home Improvement Consumer Protection Act excludes work an owner does without pay on the owner's own home, so its contract and deposit protections do not apply to you working on your own house. They apply when you pay a contractor for a job priced above $500. If you would rather hire, the steps are in how to choose a flooring contractor and the questions to ask are in questions to ask a flooring contractor. Businesses are listed on the flooring contractors directory page.
