Hardwood is most of what we do and we do all of it in-house.
If you have oak, maple or pine under carpet or tile, there's a good chance it can be brought back instead of replaced.
Hardwood floor refinishing
Full sand, optional stain, and two or three coats of finish. Scratches, gray wear paths and old orange polyurethane gone.
Refinishing details
Hardwood & LVP installation
New solid or engineered hardwood, or luxury vinyl plank for kitchens and basements. Old floor removal and subfloor prep included.
Installation details
Floor sanding
Drum and edge sanding down to clean wood, with dust containment. The step everything else depends on.
Sanding details
Floor staining
Natural, light, gray-toned or dark. We test the colors on your sanded floor so you choose from the real thing.
Staining details
Floor repair
Board replacement, pet stains, water damage, gaps, squeaks, and patching where a wall or vent was removed.
Repair details
Stair refinishing
Treads and risers sanded, stained to match the floor and finished, or new oak treads over old steps.

A small hardwood crew out of Linden, New Jersey.
Costa Flooring is owner-run. The person who comes out to measure your floor is the person who sands it. No hand-off to a crew you've never met.
Most of our work comes from referrals in Union, Essex and Middlesex counties, which means the job has to be right the first time, and the house has to be left clean.

Hallway refinish with board repairs. Patched boards blended in, sanded to bare wood, stained and finished.
Pick your color on your own floor.
A chip in a store tells you almost nothing: oak, maple and pine take color differently, and your light changes it again. So we tape samples on your sanded floor and you choose from the real thing.
Tap a color. Tones are approximate; species and finish shift them, which is exactly why we sample on your floor.

Free on-site estimate
We look at the floor in person, check the wood thickness, measure, and give you a written price. No pressure to decide on the spot.

Prep and sanding
Furniture moved, work area sealed off, floor sanded to clean wood with dust-containment equipment. Repairs happen here.

Color samples and stain
Stain samples go on your actual floor. You pick, we stain. Skip this step if you want the natural color.

Finish and walk-through
Two or three coats of finish with drying time between. We walk the floor with you before we call it done, then clean up and go.

Questions homeowners ask us every week.
It depends on square footage, the condition of the wood, how many rooms and stairs are involved, and whether you want a stain color or a natural finish. We give a written price after a free on-site visit, and the price we quote is the price you pay.
Most homes take 2 to 5 days: sanding, stain if you chose one, and two or three coats of finish with drying time between coats. You get a written schedule before we start.
Usually yes, as long as you can stay off the floors being finished. We seal off the work area and use dust-containment sanders. Bedrooms upstairs are typically fine while we finish the main floor.
Solid hardwood can usually be sanded and refinished several times, and it costs a fraction of replacement. If boards are badly water-damaged, rotted or already sanded too thin, we'll tell you and quote a repair or new installation instead.
After sanding, we apply several stain samples directly on your floor so you see the real color on your wood, in your light. You choose, then we stain the whole floor.
Yes. We sand, stain and finish treads and risers, and we can install new oak treads over existing stairs. Stairs are quoted with the floor or on their own.
