Hardwood floors age differently in every home. Some GTA living rooms look immaculate fifteen years after installation. Others start showing wear after three. If you own a home in Pickering, Ajax, Whitby, Scarborough, Markham, or North York, the honest answer to "how often should I refinish my hardwood floors?" is: it depends — but here is exactly how to figure out your number.
What Refinishing Actually Means
Refinishing hardwood floors means sanding the existing finish down to bare wood and applying a new coat of sealant. It strips away surface scratches, dullness, minor water damage, and colour fading — and gives the floor a fresh start. A proper refinish restores the original grain, colour, and sheen.
It is different from a screen-and-coat, which only buffs and recoats the existing finish without sanding. Screen-and-coat works for floors with mild wear. Full refinishing is what you need when the damage runs deeper.
How Often Should You Refinish Solid Hardwood Floors?
For solid hardwood — the kind you can sand down repeatedly — most professionals recommend refinishing every 7 to 15 years, depending on three factors:
- Foot traffic: A living room with two adults and a dog will wear differently than a formal dining room nobody uses.
- Pets: Dog claws are the single biggest accelerator of hardwood floor wear. Homes with large or active dogs often need refinishing on the sooner end of that range.
- Maintenance habits: Regular sweeping, prompt spill cleanup, and using area rugs in high-traffic zones can push a refinish out toward the 15-year mark.
Solid hardwood floors like the Appalachian Medici Red Oak and Appalachian Natural Hard Maple are ¾" thick throughout. That gives you roughly 4 to 6 full refinishes over the floor's lifetime. That means a well-maintained solid hardwood floor can last 50 to 75 years or more.
Engineered Hardwood: A Different Calculation
Engineered hardwood has a veneer of real hardwood bonded over a plywood core. You can refinish it — but only if the wear layer is thick enough. Here is a practical breakdown:
- 3mm to 4mm wear layer: Can be sanded and refinished 2 to 4 times, depending on the professional and how carefully the job is done. Products like the European Oak Driftwood 4mm fall into this range.
- 2mm wear layer: Can typically be refinished 1 to 2 times, if at all. It is easy to sand through to the plywood if you are not careful.
- Thinner engineered or laminate: Cannot be refinished. When they wear out, they get replaced.
If you are unsure how thick your engineered hardwood's wear layer is, a flooring professional can measure it by removing a floor register or looking at a board edge. If you are buying new, check the spec before you commit — it determines the floor's long-term cost of ownership.
How Toronto's Climate Affects the Timeline
The GTA experiences some of the most dramatic humidity swings in Canada. Between January's bone-dry indoor heating and July's sticky humidity, hardwood floors expand and contract constantly. This seasonal movement puts stress on the finish and the floor itself. Over years, that stress shows up as:
- Small gaps between boards in winter
- Slight cupping or crowning in areas near exterior doors
- Finish checking or micro-cracking that lets water get under the surface
Keeping your home's relative humidity in the 35–55% range year-round (using a humidifier in winter if needed) is one of the best things you can do to extend the life of your hardwood finish. Homes in Scarborough, Markham, and North York with older single-pane windows tend to see more seasonal movement than newer, better-sealed homes.
5 Signs It's Time to Refinish Your Hardwood Floors
- The scratches go past the finish. If a scratch catches your fingernail, the finish is breached. Screen-and-coat will not fix it — you need full refinishing or board replacement.
- Water damage that has caused staining or warping. A one-time spill that was wiped up quickly is different from a chronically wet area near a patio door or bathroom.
- The sheen is completely gone everywhere. If the floor looks matte and flat even after cleaning, the finish has worn through across the majority of the surface.
- Dark spots that don't come out. These usually mean water or pet urine has penetrated the finish. If sanding reveals deep staining, you may need board replacement rather than — or in addition to — refinishing.
- You can feel the grain in high-traffic areas. This is called "faceting" — the low points of the wood grain are wearing faster than the high points, creating an uneven texture. Refinishing levels the surface.
The Refinishing Process: What GTA Homeowners Should Expect
A full hardwood refinish typically takes 3 to 5 days in a GTA home, depending on the square footage and whether any board replacement is needed. Here is the general sequence:
- Preparation: Furniture gets moved out, and the crew masks off doorways and vents. This usually takes half a day.
- Sanding: A professional uses a drum sander and edge sander to remove the old finish down to bare wood. Depending on the home size, this takes 1 to 2 days.
- Staining (optional): If you want to change the floor colour, the stain goes on after sanding and gets a day to cure.
- Sealing/Topcoat: Multiple coats of finish — usually polyurethane — are applied, with light sanding between coats. Each coat needs 4–8 hours to cure before the next one.
- Final cure: The floor should not have furniture placed on it for at least 24–48 hours after the final coat. Full hardness develops over about 7 days.

When It Makes More Sense to Replace
- The floor has been refinished 4 or more times already and you are approaching the tongue-and-groove limit.
- There is widespread water damage or black mold in the subfloor.
- The boards are cupped so severely they would need extensive structural work to fix.
- You want to change from hardwood to a different flooring type (like SPC vinyl) as part of a full renovation.
For most homeowners in Pickering, Ajax, and Whitby with solid hardwood floors that were installed properly and maintained reasonably well, refinishing will be the right call — and it is almost always cheaper than a full replacement.

FAQ — Hardwood Refinishing in GTA Homes
Rental floor sanders are available, but the learning curve is steep and the results show. A botched DIY refinish can cost more to fix than hiring a professional from the start. For most GTA homeowners, hiring a pro is worth the cost.
Look at the end of a board or pull up a floor register. If the hardwood layer is 2mm or thinner, refinishing is risky. If it is 3mm or more, you have options. When in doubt, bring a photo or a board sample to Top Floorings Depot and we can help you assess it.
Sometimes. If the squeak is caused by boards rubbing against each other or against the subfloor, re-securing the boards during refinishing can reduce squeaks. But if the squeak comes from the subfloor itself or from the joists, refinishing alone will not fix it.
Costs vary depending on square footage, whether staining is included, and the condition of the floor. For an accurate estimate, have a flooring professional assess your specific situation in person. Top Floorings Depot can connect you with trusted installation contractors who provide estimates for refinishing work.
You can, but it is inconvenient. The dust and fumes mean the rooms being worked on are not usable for several days. Planning to stay elsewhere or confining yourself to one area of the home is recommended during the work.
Prefinished hardwood has an extremely durable factory-applied finish (often aluminum oxide) that is very hard to sand through. If you try to refinish it, you risk leaving visible marks where the new coat does not bond well to the existing one. Most professionals recommend against refinishing prefinished hardwood unless the boards are severely damaged and need replacing anyway.
Dry winter air — especially in heated GTA homes — causes hardwood to contract and create small gaps between boards. These gaps are normal and usually close up in summer humidity. Using a humidifier in winter to keep relative humidity in the 35–55% range minimizes seasonal movement and extends the life of your floor's finish.
