What is the average cost to refinish hardwood floors in New Brunswick per square foot?

Refinishing hardwood floors in New Brunswick costs $3–$6 per square foot on average, making it one of the best-value home improvement projects available to NB homeowners. A typical 1,000 square foot main floor refinishing project runs $3,000–$6,000 — roughly one-third to one-half the cost of replacing the floors entirely with new hardwood.

The refinishing process involves sanding the existing hardwood down to bare wood (removing the old finish, scratches, stains, and surface damage), then applying new stain (optional) and protective finish coats. The per-square-foot cost depends on several factors: the condition of the existing floors (heavily damaged or previously poorly refinished floors require more sanding passes), the type of finish you choose (oil-based polyurethane is the most common and affordable; water-based polyurethane costs more but dries faster with less odour; penetrating oil finishes are premium), and whether you're changing the stain colour (adding stain is an extra step and typically adds $0.50–$1.50 per square foot). Minor board replacement — swapping out a few cracked or damaged planks — adds cost but is far cheaper than full replacement.

Beyond the per-square-foot price, factor in furniture moving ($50–$200 per room), baseboard removal if needed for a thorough job ($2–$4 per linear foot), and the fact that you'll need to vacate the space during the process. Oil-based polyurethane requires 24–48 hours of cure time between coats (typically three coats total) and produces strong fumes, meaning the project takes 3–5 days with limited access to the rooms. Water-based finishes dry in 2–4 hours between coats and can cut the total project timeline significantly.

New Brunswick's humidity cycle directly affects the timing and success of hardwood refinishing. The ideal window for refinishing in NB is late summer through early fall (August–October), when indoor humidity is moderate and stable. Refinishing during the winter heating season, when indoor humidity drops to 20–30%, means the wood is in its most contracted state — gaps between planks are at their widest, and finish can seep between boards. Refinishing during NB's humid summer peak risks moisture interfering with finish adhesion and cure. Whichever season you choose, maintain consistent indoor humidity (35–55% RH) during and after the refinishing process for the best results.

Many older NB homes — particularly pre-1970s properties in Fredericton, Moncton, and Saint John — have original hardwood floors hidden under carpet that are prime candidates for refinishing. Solid hardwood floors can be refinished 3–5 times over their lifespan, making them a 50–100 year flooring investment with periodic maintenance. If your existing hardwood is still structurally sound with at least 2mm of wood above the tongue, refinishing is almost always the smarter financial and environmental choice compared to replacement.

Hardwood refinishing is a job that demands professional expertise. Drum sanders are powerful and unforgiving — a moment's hesitation or a wrong angle creates visible gouges and swirl marks that cannot be corrected without re-sanding. Professional refinishers also know how to handle the stain absorption differences between species, manage grain raise between coats, and feather transitions at doorways. The cost difference between renting equipment and hiring a professional is modest, but the quality difference is dramatic. Need help finding a professional flooring installer?
