Keep, refinish, cover or replace: how we decide
Refinish. A solid or engineered wood floor with enough wood left above the tongue can be sanded and refinished instead of replaced. No new flooring is made, shipped or thrown away. We refinish with Osmo Polyx-Oil, a plant-oil hardwax that is refreshed in worn spots later instead of sanded again; see natural oil refinishing.
Repair. Damaged boards, a stained patch by a door or a water-marked area in front of the sink can often be replaced board by board and blended in, which keeps the rest of the floor in service.
Cover. Many click floors can float over an existing hard floor that is flat, sound and firmly attached, when the manufacturer's installation guide allows it. That avoids demolition waste and dust. It raises the floor, so we check door clearances, transitions and appliance heights first. Carpet and cushioned floors always come out.
Replace. Replacement is the right call when the floor is too thin to sand again, the subfloor under it has failed, water damage has reached the core, or the floor is a material you want out of the house. Then the new floor is chosen by attributes you can check: renewable and natural materials, recycled content, or PVC-free construction.
Why refinishing with oil keeps a floor in service longer
A film finish such as polyurethane wears through in traffic lanes, and the usual fix is a full sanding, which removes wood each time. A hardwax oil can be refreshed in just the worn areas. Over the life of the floor that means fewer full sandings and more of the original wood left. The trade-off is lower resistance to standing water, so an oiled floor needs mats at sinks and prompt wiping.
Old floors in DC, Maryland and Virginia homes
Heart pine in Capitol Hill rowhouses and oak strip in Chevy Chase and Cleveland Park have often been sanded several times already, so the first measurement is the wood left above the tongue. Kitchens in older houses may hold several layers of resilient flooring. Resilient floors and adhesives from before the 1980s can contain asbestos, so we test suspect material before removal. Removing it is work for a licensed abatement contractor; an intact layer can often stay in place under a new floating floor instead.
Fitting the floor into a larger renovation
Flooring should go in after drywall, primer and any wet trades are finished, and once the HVAC runs so the house is at normal living humidity. Installing too early exposes a new floor to paint, plaster, water and heavy traffic, and a damaged floor replaced before move-in is the most wasteful outcome of all. We plan the sequence with you and, in occupied homes, keep one area usable while the rest is done. Our eco-friendly flooring installation page covers adhesives, dust control and disposal in detail.
Common questions
Is refinishing a wood floor more sustainable than replacing it?
Usually, when the boards have enough wood left above the tongue. Refinishing keeps the existing floor in service, and no new flooring has to be made or delivered. We measure before recommending it.
Can a new floor go over my old one?
Often, if the old floor is a single layer of flat, sound hard flooring and the new floor's installation guide allows it. Carpet and cushioned floors come out first, and we check door and appliance clearances.
What happens to the flooring you remove?
Removal is quoted per square foot by material. Clean wood offcuts, cardboard and metal trim are separated for recycling where local facilities accept them, and suspect older materials are tested for asbestos first.
