Hardwood floor refinishing in Orlando: when to refinish vs. replace

Most hardwood floors can be refinished 4-6 times in their life. Once they are out of meat above the tongue, they are out. Here is how we tell whether your floor is a refinish or a replacement before we start sanding.

First check: what kind of floor is it?

The single biggest factor — and the one most homeowners do not know about their own floor — is whether it is solid hardwood or engineered hardwood. Solid is one species, 3/4 inch thick, can be refinished 4-6 times. Engineered is a hardwood veneer (1-4 mm) over a plywood core; depending on the veneer thickness it can be refinished 0-2 times.

Pull a vent register. Look at the cross-section of the board at the edge of the duct opening. If you see plywood laminations underneath the top layer, it is engineered. If it is uniform wood all the way down, it is solid.

Solid hardwood — usually refinish

Even with deep dog scratches, water rings, and 30 years of UV bleach, a solid floor with at least 3/16 inch above the tongue is a refinish candidate. We sand down to bare wood, fill gouges as needed, and recoat. Cost in Orlando: $3.50-$5.50 per sq ft. A 1,200 sq ft house runs $4,200-$6,600 for a full refinish.

Replacement cost for the same area in matching new solid hardwood: $12,000-$18,000 installed. The math is not close.

Engineered hardwood — usually replace

If your engineered floor has a thin veneer (2 mm or less, which is most pre-finished engineered installed since 2010), it is not really refinishable. We can do a light screen-and-recoat to refresh the finish, but the underlying wood is the underlying wood; you cannot sand it.

If the veneer is 4 mm+ (typical of pre-2005 engineered or the high-end stuff today), one refinish is possible. After that, replace.

Water damage — the make-or-break test

Cupping (boards arched up at the edges) and crowning (boards arched up in the middle) come from moisture. Mild cupping flattens after a few weeks once the source is fixed and the floor dries — we then refinish normally. Severe cupping or any black staining means the wood is compromised; replacement of the affected area is the only fix, and we have to color-match the new boards to the surrounding sanded floor.

Pet stains — the hidden problem

Cat urine in particular soaks deep and turns wood black. Sanding will not remove it because the stain is in the wood, not on it. We can sometimes bleach pet stains out with oxalic acid; for severe cases the boards need to be replaced.

Process timeline

A typical 1,200 sq ft refinish takes 4-5 days:

• Day 1: coarse sand (36-grit), then progressively finer (60, 80, 100).
• Day 2: edging (around the perimeter where the drum sander does not reach), corner sand, vacuum.
• Day 3: stain (if changing color) + first poly coat.
• Day 4-5: second + third poly coat, light buff between.

You can usually walk on the floor in socks 24 hours after the last coat. Furniture goes back 72 hours after. Rugs at 30 days (rugs trap solvents and can leave a haze).

Stain colors — what holds up in Florida

Light + medium tones (provincial, golden oak, natural) hold their look the longest because they hide UV-bleaching better. Dark espresso and ebony stains look great new but start showing scratches and sun-fade within 18 months in a Florida living room with east-facing windows. If you want dark, plan on a refinish every 5-7 years; if you want set-and-forget, go natural or provincial.
