Hardwood floor maintenance in Ontario

35 to 55 percent

That is the relative humidity band a hardwood floor wants. Ontario houses routinely miss both ends. A humidifier in January is cheaper than a refinish in April. Gaps in February are not a defect if the house is at 18 percent. They are physics.

A cheap hygrometer in the main living space is the single most useful thing a hardwood owner can buy. It turns an argument about whether a floor is faulty into a reading anyone can check, and it tells you when to run the humidifier rather than guessing.

What actually wears a floor out

Grit. Not heels, not dogs, not furniture — grit tracked in on shoes, which is sandpaper being walked across a finish. A mat at every exterior door and a habit of taking shoes off does more for a floor's life than any product sold to protect it.

After grit, the two big ones are UV and water. UV ambers oak unevenly, so a rug left in one place for five years leaves a shadow that only sanding removes — rotate rugs occasionally. Water sits in the seams at the dishwasher, the fridge line and the back door, which is where nearly every failure we are called to starts.

Cleaning, briefly

Dry first: sweep or vacuum with a hard-floor head. Then a barely damp microfibre with a cleaner made for the finish on your floor. That is the whole method.

Steam mops are not cleaning. They are a slow flood with a warranty exclusion attached, and most finish manufacturers say so explicitly. Vinegar and water is a folk remedy that dulls a waterborne finish over time. Oil soaps leave a residue that stops the next recoat bonding, which is a problem you discover years later when the recoat peels.

Recoat before you sand

A screen-and-recoat every four to eight years in a family house keeps the wear layer you already paid for. It is abrading the finish and adding a fresh coat, not touching the wood — a day's work rather than a week's, at a fraction of the cost, with no dust of consequence.

The window matters. Once traffic lanes have worn through the finish into bare wood, a recoat cannot fix it and the floor needs a full sand. The tell is a dulled path that stays dull after cleaning, usually from the back door to the kitchen. That is the moment to book a recoat, not to wait another year.

A full sand is for colour changes and for floors whose finish is genuinely gone. Solid hardwood has a limited number of sands in it; spending one on something a recoat would have solved is spending wear life you cannot get back.

Hardwax oil is a different relationship

An oil-finished floor is maintained rather than recoated: it takes a refresher oil periodically, and in exchange it can be spot-repaired without touching the rest of the room. A film finish cannot — a scratch through polyurethane means resanding to a break line.

Neither is better. One is lower attention with harder repairs; the other is higher attention with easier ones. Choose knowing which you are buying.
