How to Care for Hardwood & Custom Woodwork

Good woodwork is an investment — hardwood floors, custom cabinetry, built-ins and trim that were built to last decades. Looked after, they will. Neglected or cleaned wrong, they age far faster than they should. Here’s how to keep the wood in your home looking the way it did the day we finished it, from a carpenter who’d rather you never needed a refinish.

Understand your finish first

Before you clean anything, know what’s protecting it. Most modern floors and woodwork wear a hard surface finish — polyurethane, water-based or oil-based — that sits on top of the wood like a clear shell. Older or bespoke pieces may carry a penetrating oil or wax finish that soaks in and feels more natural but needs different care. The two are not cleaned or repaired the same way, so if you’re unsure, test in a hidden spot or ask whoever built it. Everything below assumes a surface finish unless noted.

The daily and weekly routine

The enemy of wood is grit and standing water. Grit acts like sandpaper underfoot, scratching the finish a little more with every step; water works into seams and lifts finish over time. So the routine is simple: sweep or dry-mop often, vacuum with a soft brush head, and wipe spills the moment they happen. Place mats at exterior doors to catch the sand and salt that Toronto winters track in — road salt is especially hard on floor finish.

For a proper clean, use a cleaner made for your finish, sprayed lightly onto a microfibre pad rather than poured on the floor. Never use a soaking-wet mop, and never use vinegar, ammonia, or oil soaps on a polyurethane finish — vinegar is a mild acid that dulls the sheen over time, and oil soaps leave a residue that ruins the look and interferes with any future recoat.

Ninety percent of premature wear on wood floors comes down to two things — grit that wasn’t swept and water that sat too long. Fix those two habits and your floors will outlast your mortgage.

Protecting cabinetry, built-ins and trim

Vertical woodwork lives an easier life than floors, but kitchens are the exception. Heat and steam are the main threats to cabinetry — run the range hood when you cook, and wipe cabinet faces near the stove and dishwasher where steam settles. Dust built-ins and shelving with a slightly damp cloth, dry immediately, and keep them out of direct blasting sunlight where you can, since UV slowly ambers and fades wood tone. For handled edges and trim near doorways, a periodic wipe keeps hand-oils from building up on the finish.

Humidity: the invisible factor

Wood moves with moisture in the air, and Toronto’s swing from humid summers to bone-dry heated winters is hard on it. In winter, forced-air heat can drop indoor humidity low enough to shrink boards and open small gaps between floorboards or panel joints; in summer, high humidity swells them shut again. Small seasonal gaps are normal and not a defect. But keeping indoor humidity in the 35 to 50 percent range year-round — a humidifier in winter, good ventilation in summer — dramatically reduces the movement and the stress on every glued and fitted joint in the house.

When it’s time for professional help

Surface finishes can often be screened and recoated — lightly abraded and given a fresh top coat — before they wear through to bare wood, which is far cheaper than a full sand-and-refinish. Watch for dulling in traffic lanes and catch it early. Deep scratches, water stains that have gone black, or worn-through patches usually mean a full refinish of that area. And a wobbly stair railing or a squeaking tread is a safety issue, not a cosmetic one — worth fixing promptly.
