Bedroom oak floor refinished to a glossy finish by Costa Flooring, Union County NJ
Hardwood floor refinishing · Linden, NJ & Union County

Hardwood floor refinishing in Union County, sanded and finished like new.

Scratched, gray or orange floors in Linden and across North Jersey: the old finish and the worn top layer come off, and the scratches, wear paths and 1990s tint go with them. Most homes take 2 to 5 days.

What's included

Refinish instead of replace, and keep the floor you already have.

If you have solid oak, maple or pine, it can almost always be refinished instead of replaced. Every refinishing job includes:

  • Moving furniture out of the work area and sealing off doorways
  • Three-stage sanding (drum, edge, buffer) down to bare wood, with dust containment
  • Filling gaps and nail holes, minor board repairs
  • Stain samples applied on your floor if you want a color change
  • Two or three coats of finish: matte, satin or gloss
  • Cleanup and a walk-through with you before we leave
Refinish or replace?

Solid hardwood can be sanded several times over its life.

We check the thickness at a floor vent or threshold during the estimate, and tell you plainly which option makes sense.

Solid 3/4" hardwood

Enough wood on top to be sanded several times. If there's thickness left, refinishing is the better deal by a wide margin.

Engineered hardwood

A thick wear layer can often be refinished once. Thin-veneer engineered floors and laminate can't be sanded.

Too thin, rotted or water-damaged

If the floor has been sanded too many times or has serious damage, we'll say so and quote a repair or a new installation instead.

How it works

What the week looks like, day by day.

You get a written price and a written schedule before the sander comes in.

  1. Day 1: sanding

    The loudest, dustiest day, kept in check with containment equipment. Repairs and gap filling happen here.

  2. Day 2: color

    Stain samples on your floor, then stain if you chose a color. Natural floors skip straight to finish.

  3. Days 3–5: finish coats

    Two or three coats with drying time between each. You can walk in socks after the last coat dries.

  4. Walk-through

    We walk the floor with you before we call it done, then clean up. Furniture goes back in a few days, rugs in about two weeks.

You can usually stay in the house. Upstairs bedrooms are fine while we work on the main floor; if the whole house is being done at once, we'll plan the order with you.

Finish options

We recommend a finish based on how the room is used.

Water-based finish

Dries fast and stays clear, so light and white-washed floors keep their color instead of going amber.

Oil-modified polyurethane

The classic warm amber look on oak. Longer drying time between coats.

Sheen: matte to gloss

Matte, satin, semi-gloss or gloss. Satin hides small scratches best and is what we recommend for most homes.

FAQ

Refinishing questions we hear every week.

Surface stains, yes. Deep black urine stains that have soaked into the wood usually need the boards replaced, which we can do as part of the job.

If you want the same look, we stain to match. If you want a change, this is the moment to do it. See floor staining.

Yes. One room, a hallway, a whole floor or the whole house.

Usually yes. Upstairs bedrooms are fine while we work on the main floor. If the whole house is being done at once, we plan the order with you.

Engineered hardwood with a thick wear layer can often be refinished once. Thin-veneer engineered floors and laminate cannot; we'll tell you at the estimate.
