What refinishing actually costs in 2026
Hardwood floor refinishing in Ontario currently runs $3 to $8 per square foot in 2026 for a standard sand-and-finish project. The final hardwood sanding price depends entirely on the condition of your floor and the finish system you select.
Our estimators see basic projects sitting at the low end around $3 to $4 per square foot. These are simple sanding jobs with a natural clear finish on a floor in good condition.
A full restoration with stain matching and three coats of premium Bona Traffic HD finish on a Toronto heritage property will sit at the higher end of $7 to $8 per square foot. Heritage restoration with intricate board repair and reclaimed material sourcing runs well above this band at $8 to $18 per square foot.
For broader context, the full Ontario hardwood flooring cost guide covers material, installation, and refinishing together. This specific guide focuses exclusively on refinishing.
We get asked about this single service more than anything else in the GTA. It provides the absolute strongest cost advantage over a full floor replacement.
Cost by room size
A standard 300 to 500 square foot Toronto living room will cost between $1,200 and $4,000 to refinish in 2026. Whole-house main floors generally run from $4,000 to $11,200.
We find that looking at total room costs is much more practical than staring at a refinishing price per square foot. Small rooms like bedrooms often have a slightly higher square-foot rate due to the minimum labor and setup times required by professional crews.
| Room Size | Square Feet | Refinish Cost Range |
|---|---|---|
| Bedroom | 150-250 | $600-$2,000 |
| Living room | 300-500 | $1,200-$4,000 |
| Open-concept main | 800-1,200 | $3,200-$9,600 |
| Whole house main floor | 1,000-1,400 | $4,000-$11,200 |
| Whole house with upstairs | 1,800-2,500 | $7,200-$20,000 |
These ranges assume a standard scope of work without deep water damage or pet stains. Significantly damaged floors, custom stain matching, staircases, and heritage board replacements will push the final bill beyond these standard brackets.
What’s included in the price
A standard Bona Certified refinishing project at our 2026 rates includes full dust containment, a multi-stage sanding process, and premium waterborne finishing. The proposal itemizes everything so you know exactly what goes into the final number.
- Dust containment setup. We attach a Bona DCS system to every sanding machine. A HEPA vacuum runs constantly to protect your home. Work zones are completely sealed off with heavy poly sheeting.
- Full grit-sequence sanding. The process involves 36, 60, 80, 100, and 120 grit passes on a drum sander, edger, and orbital buffer. The crew also trowel-fills minor cracks and gouges to ensure a flawless surface.
- Optional stain. A natural clear finish is the default choice. Custom stain matching typically adds 10 to 15 percent to the total project cost.
- 2-3 coats of premium finish. We exclusively use Bona Traffic HD waterborne polyurethane or Rubio Monocoat 2C hardwax oil for heritage spaces. Bona Traffic HD features very low VOCs under 150g/L and reaches a 100 percent cure in just 3 days, compared to a full 30 days for traditional oil-based poly.
- Baseboards and quarter-round. Reinstalling your existing trim is included in the base rate. Supplying and installing new material is quoted separately if the existing pieces are too damaged to reuse.
- Final cleanup. Our crews perform a thorough HEPA vacuum and surface wipe-down. This returns your living spaces to their pristine pre-project condition.
Common add-ons and what they cost
The most common add-ons for a refinishing project include staircases at $100 to $200 per step and subfloor moisture mitigation at $500 to $2,000. These elements fall outside a basic sand-and-finish scope because they require specialized labor and materials.
- Stairs: Expect to pay $100 to $200 per stair. Staircases require precision hand-tool work. Sanding and finishing each tread and riser takes five to ten times the labor of an open flat floor.
- Custom stain matching: This adds $200 to $500 in specialized labor. The fee covers sample iterations, on-site client approval, and custom blend formulation.
- Heritage repair (board replacement): Replacing major board sections costs $400 to $1,200. You will pay more for intricate parquet repair or sourcing specific reclaimed original boards.
- Subfloor remediation: We quote this separately based on our exact on-site findings. Self-levelling a concrete slab adds $2 to $4 per square foot. Correcting major moisture issues adds $500 to $2,000 to the total budget.
Why our pricing is fixed-price written quote
We provide a written fixed-price quote within 48 hours of our free in-home visit. The estimate locks in the total for the exact scope quoted.
You will see every line of the project itemized, from the sanding and stain to the premium finish and cleanup. The final price will not change unless hidden structural issues are uncovered during the work.
Finding a rotten subfloor during sanding or discovering high moisture readings on adjacent walls will require an adjusted scope of work. We only revise the quote if you request design changes or if these strict safety thresholds are breached.
Cost vs replacement value
A 500 square foot Toronto living room refinish runs $1,800 to $4,000 all-in, which is roughly 30 to 40 percent the cost of a full floor replacement. Ripping out an old floor and installing brand new solid hardwood typically costs between $9 and $25 per square foot in 2026.
We see comparable new solid hardwood installations running $4,500 to $9,000, plus an additional $500 to $1,500 just for the demolition and disposal of the old boards. Refinishing your existing wood is consistently the most economical choice. It also preserves the original heritage character of older Toronto homes.
