Hardwood Floor Refinishing in Fremont, CA

Hardwood floor refinishing means sanding the floor to bare wood and building a new finish on top. It is the right job when the finish has worn through to gray wood in walkways, when there are deep scratches or pet stains, or when you want to change the color. Plenty of Fremont ranch homes from the 1950s and 1960s have oak strip floors that have been under carpet for decades and refinish well.

Signs your floor needs a full refinish

• Gray or bare spots where the finish is gone, usually in hallways, at the kitchen entry and in front of the sofa
• Scratches that catch a fingernail or go through the color
• Dark water marks or pet stains that have soaked into the wood
• An old orange or yellowed finish you want to replace with a lighter or darker tone

If the finish is just dull and lightly scuffed, a screen and recoat may be enough, and it costs much less.

How sanding works

We sand in stages with a drum or belt sander, starting coarse enough to cut through the old finish and moving to finer grits to smooth the wood. An edger handles the perimeter and a hand scraper gets corners and under radiators or cabinets. Between passes we fill nail holes and small gaps. Each pass removes a little wood, so we check board thickness first; floors that have been sanded many times, or engineered floors with a thin wear layer, may not have enough left.

Choosing a stain color

Natural red oak has a pink-tan tone; white oak is more gray-brown. Stain changes that, but it looks different on every floor. We apply sample patches on your sanded floor so you can see them in your own light before we commit. Fixr and Today's Homeowner both list staining as an add-on of about $1 to $3 per square foot.

Finish options and VOC rules

Most floors here get a water-based polyurethane or an oil-modified polyurethane. Water-based finishes stay clear, dry faster and have less odor; oil-modified finishes deepen the amber color of oak and take longer between coats. California limits volatile organic compounds in coatings (CALGreen sets 275 grams per liter for wood coatings, for example), and the Bay Area air district has its own coatings rule, so the finishes we use are formulated for those limits. If anyone in the household is sensitive to odors, tell us and we will plan the product and schedule around it.

Dust and timing

Modern sanders collect much of the dust, but not all of it. We seal doorways with plastic, cover vents and remove what we can from the rooms. Fixr lists dustless refinishing systems at about $6 to $8 per square foot, compared with $3 to $5.50 for standard sanding and refinishing. A typical job takes a few days: sanding on the first day, stain and coats of finish over the following days, then cure time before rugs and heavy furniture go back.
