Wood Floor Refinishing

Sanding, staining and recoating worn hardwood, with the build year and wear layer checked before any sander touches the floor.

Upland Wood Flooring has been doing wood floor refinishing in Upland, CA for more than 20 years, serving surrounding cities including San Antonio Heights, Claremont, Montclair, Rancho Cucamonga and La Verne. We sand worn hardwood back to clean wood, repair what needs it, and apply a new finish that suits the floor and the household using it.

A refinish is only as good as the decisions made before the sander starts. We confirm when the house was built, measure how much wood the floor has left, and check for damage that sanding would only hide. More than half of Upland’s homes were built before 1980, so many of the floors we see have been sanded before and need careful handling.

We also plan around your household. Dust containment keeps the sanding in the rooms being worked, and a written cure schedule shows which rooms close and when they reopen, so you can plan meals, pets and work around the job.

When a Full Sanding Is the Right Job

A full refinish takes the floor down to bare wood and removes everything above it: worn finish, gray traffic lanes, deep scratches, stains and old color. It is the right job when wear has reached the wood itself, or when you want a different stain color. The result is effectively a new surface on the original boards.

We work through a grit sequence with a drum sander on the field and an edger along the walls, then finish with an orbital sander or buffer to remove sanding marks. Each pass is lighter than the one before, which keeps the cut as shallow as the damage allows and saves wood for the next refinish.

When a Screen and Recoat Will Do

A screen and recoat lightly abrades the existing finish and adds a fresh coat without sanding into the wood. It suits floors that look dull or lightly scuffed but have no bare spots. It takes less time, makes far less dust and removes no wood, which matters on older or thinner floors.

The limit is adhesion. A recoat will not bond to a floor that has been waxed or treated with some polishes, and it can peel within weeks. We test the existing finish before recommending a recoat, and if it will not hold, we tell you rather than applying a coat that will fail.

Floors That Need Repair First

Some floors cannot be refinished well until they are repaired. Cupped boards, hollow spots, pet urine stains and water damage all show through a new finish. We repair or replace those boards first, matched to species and width, so the refinish covers a sound floor.

Repairs are woven into the floor rather than cut in as a square patch. New boards are staggered into the surrounding rows so their ends fall at different points, the way the original floor was laid. After sanding and finishing the whole room together, a well-woven repair is hard to find.

Checks Before the Sander Starts

Build Year and Painted Trim

The EPA RRP rule covers paint disturbed in homes built before 1978, and refinishing often reaches baseboards, shoe molding and stair trim. We confirm the build year before any sanding so we know whether that trim needs lead-safe handling. It is a simple check that prevents a serious mistake in an older house.

For a pre-1978 house, the answer changes how the room is set up. Painted trim that has to come off or be sanded is handled with lead-safe work practices, containment and cleanup, while trim that can stay in place is protected and left alone. We explain which applies before the job is scheduled.

Remaining Wood and the Engineered Wear Layer

Solid hardwood has a limit, set by the distance between the surface and the tongue. Engineered flooring has a harder limit, because only the top wear layer can be sanded. We measure both at a floor register or threshold before quoting, and if the floor cannot safely take a full sanding, we say so up front.

Insects, Moisture and Hidden Damage

Before sanding, we look for drywood termite frass, powderpost beetle holes, board gapping and moisture problems. Refinishing over any of them only hides a problem that will return. When we find one, we explain what it means and what should happen first, whether that is a treatment, a plumber or board replacement.

A moisture meter reading on suspect areas is part of every walkthrough. Boards that read wetter than the rest of the floor near a kitchen, bathroom or exterior door usually point to a leak or a drainage problem. Sanding a floor while it is still moving with that moisture leaves an uneven surface once it dries.

Stain, Finish and Sheen

Choosing a Color on Your Own Floor

Wood species decide how stain behaves. Red oak takes color readily, white oak shows more of its grain, and maple can go blotchy without careful preparation. We lay down sample patches of floor stain on your sanded boards, and where a darker color needs to take evenly, we use water popping to open the grain first.

Many owners simply want the orange tone of an aged oil finish gone. A clear waterborne finish on sanded red oak or white oak brings back a lighter, more natural look without any stain at all. We show you both options side by side before you decide.

Finishes That Meet Rule 1113

South Coast AQMD Rule 1113 sets a limit of 275 grams per liter for wood coatings in this air basin, and it applies to the products used on your floor. Every finish we use is chosen to meet it. That rules out some products sold in other states, but the compliant finishes available here perform well.

We work mainly with waterborne polyurethane, oil-modified polyurethane and hardwax oil. Waterborne finishes dry clear and fast and have a lower odor. Oil-modified polyurethane adds warmth, while hardwax oil gives a low-luster look and can be spot-repaired later without a full sanding.

Sheen Level and Everyday Wear

Sheen level changes how a floor looks and how it ages. Gloss shows every scratch and footprint, while satin and matte hide daily wear far better. Most households we work for choose satin or matte, and we can show you samples in your own light before the final coat.

The finish also sets how you maintain the floor. Polyurethane floors want a pH-neutral cleaner and an occasional screen and recoat once the surface dulls, while a hardwax oil floor is refreshed with maintenance oil. We leave written care instructions matched to the product, so the refinish lasts as long as it should.

Our Step-by-Step Wood Floor Refinishing Process

Step 1: Walkthrough and Written Scope

We inspect the floor, confirm the build year, measure the remaining wood, and test the finish. You receive a written scope listing each room, any repairs, the stairs by tread and riser, and the recommended finish.

Step 2: Containment and Protection

We move out what needs moving, seal doorways and vents, and protect cabinets and walls. Sanders run with vacuum extraction so the dust stays in the work area rather than traveling through the house.

Step 3: Repairs, Sanding and Filling

Board repairs come first, then the sanding sequence. Gaps and small defects are filled with wood filler or by trowel filling across the floor, and a final pass leaves the surface ready for color.

Step 4: Stain, Coats and Cure Schedule

Any stain goes down first, followed by the finish coats with light abrasion between them. We leave you the written cure schedule with the dates for walking, furniture and rugs, plus care instructions for the finish we used.

Frequently Asked Questions

How many times can a solid hardwood floor be refinished?

It depends on how much wood remains above the tongue and how hard earlier sandings cut into it. A standard solid floor that has been sanded carefully can often take several more. We check the remaining thickness at a register or threshold before quoting, rather than guessing from the floor's age.

Is a screen and recoat enough for my floor?

It is enough when the wear is only in the finish: dullness, light scuffs and fine scratches. If the finish has worn through to gray wood, or stains and dents reach the boards, a full sanding is the right job. We show you which areas fall on each side of that line.

Can you change the color of my floor?

Yes, once it is sanded to bare wood. We apply floor stain samples on your own boards so you see the color on the actual species in your light. Red oak, white oak and maple each take stain differently, which is why samples matter more than a brochure.

How are stairs priced when the rest of the floor is refinished?

Stairs are priced by the tread and riser, separately from the square footage of the rooms. Each step is sanded and finished by hand, so a per-step price reflects the actual work and keeps the room price from hiding it.

How long before we can walk on the floor?

Most finishes allow careful sock traffic within a day of the last coat, but furniture and rugs wait longer while the finish cures. The written cure schedule we give you sets out each of those dates for your finish, so there is no guesswork.

Do you refinish engineered hardwood?

We do when the wear layer is thick enough to sand. We measure it before promising anything, and when it is too thin for a full sanding we offer a screen and recoat instead of risking a cut through to the core.

What finish is most durable for a busy household?

A quality waterborne polyurethane in two or three coats holds up well to children and pets and stays clear. Oil-modified polyurethane gives a warmer color, and hardwax oil is easier to spot-repair. We match the finish to your traffic and how you want to maintain the floor.

Will refinishing remove pet stains?

Surface marks usually sand out, but pet urine stains that have turned black have soaked deep into the wood. We test a stained area first, and when the stain stays, we replace those boards before refinishing so the room finishes evenly.
