Hardwood floor refinishing can make a tired, scratched floor look close to new, but the job varies more than most people expect. Some floors need a full sand down to bare wood. Others only need a light buff and a fresh topcoat. And some floors that look like wood cannot be sanded at all. Quotes differ for the same reasons.
This guide is for homeowners and renters in the United States and the United Kingdom. It covers the two main options, how to tell what floor you have, finishes and cure times, dust and ventilation, how to hire a flooring pro on each side of the Atlantic, what sets the cost, and how the job usually runs from the first visit to the warranty.
Hardwood floor refinishing: sand and refinish, or screen and recoat
There are two main routes, and the right one depends on how deep the wear goes. A good flooring pro looks at the floor before recommending either.
| Job | What it involves | When it fits | What changes the time and price |
|---|---|---|---|
| Full sand and refinish | The old finish and a thin layer of wood are sanded off to bare wood, then an optional stain and several coats of finish. | Deep scratches, dents, grey or water-marked areas, finish worn through, or a new stain colour. | Floor area, condition, sanding passes, stain, number of coats. |
| Screen and recoat | The existing finish is buffed to roughen it, cleaned, and a new topcoat is applied. No bare wood. | Finish is dull or lightly scuffed, but has not worn through and the wood is undamaged. | Floor area, whether the old finish accepts a new coat, number of coats. |
| Repairs and board replacement | Damaged, loose or stained boards are cut out and replaced, gaps filled, raised nails set. | Pet stains, water damage, squeaks, missing or split boards. | Number of boards, matching the species and width, access. |
| Stairs and edges | Treads, risers and nosings worked largely by hand; edges and corners done with smaller machines. | Usually part of a whole-floor job. | Number of steps, spindles and detail work. |
A screen and recoat is quicker and involves less work, but it cannot fix damage that goes into the wood. If you can see bare or grey wood where the finish has worn through, a new topcoat will not hide it. The pro should also check whether the old finish will bond with a new coat. Floors that have been treated with some polishes or waxes may not accept one without a full sand.
DIY refinishing kits and rental sanders exist. A light recoat can be manageable for a careful DIYer, but a full sand is far less forgiving. A heavy sander held in one place can gouge the boards, and on engineered wood it can cut through the wear layer. If you are unsure, have a pro assess the floor first.
Know what floor you have before you call
Tell the pro what floor you have, or ask them to identify it on the first visit. It decides whether sanding is possible at all.
- Solid hardwood: one piece of wood all the way through. It can usually be sanded several times over its life, though each full sand removes some wood.
- Engineered hardwood: a top layer of real wood, the wear layer, on a plywood or similar base. It can be sanded only if the wear layer is thick enough. A pro can often check it at a floor vent, a threshold or the edge of a board.
- Laminate and vinyl: a printed surface, not real wood. They cannot be sanded or refinished. Worn areas are fixed by replacing planks.
If the floor has already been sanded before, say so. Visible nail heads or exposed board edges can be a sign that little wood is left, and a pro may suggest a recoat or repairs instead.
Choosing a finish
The finish is the protective layer on top. Each type looks and behaves differently, so ask to see examples.
- Water-based polyurethane: low odour, dries faster between coats, and stays close to the natural colour of the wood.
- Oil-based polyurethane: gives a warmer, amber tone, has a stronger odour and needs a longer cure.
- Hardwax oil: soaks into the wood for a more natural, matte look. Worn spots can often be touched up, but it may need more regular care.
Drying and curing are not the same thing. A floor can be dry enough to walk on in socks long before it is fully cured. Put furniture back and lay rugs only after the cure time the pro specifies, and follow the finish manufacturer’s guidance on cleaning products. Ask for the times in writing so everyone in the house knows them.
Stain and colour changes
A stain changes the colour of the wood before the finish goes on. Going lighter or darker means a full sand to bare wood; a recoat cannot do it. Ask for a test patch on your own floor, because the same stain looks different on different woods.
Dust, pets and ventilation
Sanding creates fine dust. Ask whether the pro uses a dust-containment sanding system, where the sanders are connected to a vacuum that captures most of the dust at the source. Even then, plan for some dust.
- Keep pets and children out of the work area, and ideally out of the house during sanding and finishing.
- Turn the heating and air conditioning off during finishing, so dust and fumes are not pulled through the house and onto the wet floor.
- Ask the pro to seal doorways to rooms that are not being worked on.
- Ask about ventilation and when it is safe to come back, especially with oil-based finishes.
Plan where you will stay: with a full sand and several coats, you may not be able to use the rooms, or even parts of the house, for some days. Ask for a day-by-day plan before you book, including when each coat goes on and when the floor will be ready for furniture.

Get two or three written quotes, ideally after a visit. A pro who quotes without seeing the floor cannot know its type, its condition or how much repair it needs.
In the United States
Licensing rules for flooring contractors vary by state, and sometimes by city or county. Check with your state or local licensing office what applies where you live. Whatever the rules, ask for proof of insurance before work starts. Ask for a written estimate per square foot that lists the steps: sanding passes, repairs, stain and the number of coats. That lets you compare quotes like for like.
In the United Kingdom
Ask for a written quote, not a verbal price, listing the rooms, the preparation, the finish and the number of coats. Ask whether the business has public liability insurance, in case furniture, skirting or the property is damaged. If you rent or live in a flat, check with your landlord or building management before booking.
In both countries
- Photos of previous work, ideally on floors like yours.
- A written warranty, and what it covers and for how long.
- Who will actually do the work, and whether they will be on site every day.
- When payment is due, and what happens if the schedule slips.
Hardwood floor refinishing cost: what sets the price
A figure from someone else’s home cannot price yours. These are the items that move the number:
- Floor area: square footage in the US; in the UK the quote may be by area or as one price for the job.
- Floor condition: deep damage means more sanding passes.
- Repairs and board replacement: especially where boards must be matched.
- Stairs: slow, detailed work, usually priced separately.
- Stain colour change: an extra step, and it needs a full sand.
- Finish type and number of coats: more coats mean more time.
- Moving furniture: whether it is included, and which pieces they will not move.
When you compare, check that each quote covers the same rooms, the same option, the same finish and the same number of coats. A low quote that leaves out repairs or counts fewer coats is not really cheaper. Then look at the job posts and local pros around you to see who is available.
How the job usually runs
- Visit: the pro identifies the floor, checks its condition and discusses options and finishes.
- Written quote: rooms, steps, finish, coats, timing and warranty.
- Preparation: furniture moved, rugs lifted, doorways sealed.
- Sanding and repairs: boards replaced, gaps filled, floor sanded or screened.
- Stain and coats: applied with drying time between each coat.
- Cure and handover: a walk-through, a written invoice and the warranty.
If you are also repainting walls or skirting, agree the order with both trades so new paint is not scuffed by sanders and drips do not land on a fresh finish. Our guide on how to hire a painter covers that side of the work.
Questions to ask a flooring pro
- Is my floor solid, engineered, or something else?
- Do I need a full sand, or will a screen and recoat do?
- Which finish do you recommend, and what are the drying and cure times?
- Do you use a dust-containment system?
- Can I have a written quote listing every step and coat?
- Can I see proof of insurance and photos of previous work?
- What does your warranty cover?

In short
Find out what floor you have before anything else. Choose a full sand for real damage or a colour change, and a screen and recoat for a worn but intact finish. Pick the finish for the look and the cure time you can live with. Ask about dust containment, keep pets and children out, and turn off heating and air conditioning during finishing. Get written quotes, check insurance and, in the US, your state’s licensing rules, and get the warranty in writing.
