How Much Does It Cost to Refinish Hardwood Floors?

Hardwood floors add timeless beauty and value to any home, but years of foot traffic can take a toll. Understanding how much sanding hardwood floors costs, the cost to refinish hardwood floors and other factors helps you budget for this home improvement project. Scratches, dullness and wear patterns eventually make wood floors look tired and dated. When your floors reach this point, refinishing offers a cost-effective way to restore the original luster without the expense of replacement.

The refinishing process breathes new life into worn hardwood by removing the damaged surface layer, then applying fresh stain and protective coating. Most homeowners find refinishing far more economical than installing new floors, and the results can last another decade or more with proper care.

How Much Does It Cost on Average to Have Hardwood Floors Professionally Refinished?

According to HomeGuide, refinishing hardwood floors costs $2 to $8 (CAD 2.82 to CAD 11) per square foot or $800 to $3,200 (CAD 1,128 to CAD 4,510) total on average for a 400-square-foot space. Most homeowners spend around $1,500 to $2,000 (CAD 2,114 to CAD 2,819) for a typical project covering several rooms.

Simple projects with floors in relatively good condition fall toward the lower end of this range. Larger areas bring down the per-square-foot price since contractors can spread costs across more space. Many flooring companies offer volume discounts when refinishing multiple rooms.

Complex projects can push costs higher. Floors with deep scratches, water damage or severe wear typically require more intensive sanding. Exotic hardwoods demand specialized techniques, and that increases the labor time. Premium finishing options like dustless refinishing can also raise the total expense.

Can My Hardwood Floor Be Refinished?

Most solid hardwood floors can be refinished multiple times throughout their lifespan. According to The Spruce, solid hardwood planks are typically able to withstand aggressive sanding throughout the plank's thickness. Depending on how aggressively the planks are sanded, they should be able to withstand multiple refinishing cycles before the wood gets too thin.

Engineered hardwood presents a different situation. These floors feature a thin hardwood veneer bonded to plywood layers beneath. Engineered floors with thick wear layers of one-eighth inch or more can typically handle one or two refinishing cycles. Those with thinner veneers may not survive even a single sanding and should be replaced instead.

Deep gouges that penetrate through to the subflooring, extensive water damage or widespread loose boards may indicate problems beyond what refinishing can address. In these cases, board replacement or complete floor replacement provides a better solution.

How Much Does Sanding Hardwood Floors Cost?

Sanding is one of the main components in the refinishing process, and the cost is typically included as part of the larger process. However, most contractors include sanding in their total refinishing quote rather than itemizing it separately. The sanding hardwood floors cost varies based on the floor's condition and the depth of sanding required.

Professional floor sanders use specialized drum sanders and edging tools to remove the old finish and smooth the wood surface. Light sanding for floors with minimal wear requires fewer passes with finer-grit sandpaper. Heavily damaged floors need aggressive sanding, starting with coarse-grit paper, then progressing through finer grits.

Wood type influences sanding difficulty and cost. Soft woods like pine sand quickly but clog sandpaper more frequently. Hardwoods like oak and maple take longer to sand but produce cleaner results.

How Much Does It Cost to Sand, Stain and Refinish Wood Floors?

Staining adds about $1 (CAD 1.41) per square foot to your refinishing project. This optional step allows you to change your floor's color or enhance the wood's natural tones. Many homeowners choose to restain when refinishing to update their home's look.

Professionals apply stain after sanding, allowing it to penetrate the wood before wiping away excess. Achieving darker colors often requires multiple stain applications, which increases both material costs and labor time.

After staining comes the finishing coat, which costs $2 to $8 (CAD 2.82 to CAD 11) per square foot. According to Family Handyman, polyurethane remains the most popular choice, available in oil-based and water-based formulations. Oil-based polyurethane costs less up front and provides excellent durability but takes longer to dry. Water-based polyurethane dries faster and produces fewer fumes but typically costs more per gallon.

Labor is the largest portion of refinishing expenses, accounting for up to 80% of the total project cost. Professional flooring contractors' rates vary depending on their experience level and your geographic location, with metropolitan areas typically commanding higher prices.

Materials like sandpaper, stain and polyurethane make up the remainder of project costs, with premium products increasing the total expense.

What's the Difference Between Hardwood Floor Refinishing and Restoration?

Refinishing and restoration serve different purposes and involve varying levels of work.

Refinishing focuses on the floor's surface. This process sands away the old finish and damaged top layer of wood, then applies fresh stain and protective coating. Refinishing addresses cosmetic issues like scratches, dullness and minor wear, but it doesn't deal with structural problems.

Restoration involves more comprehensive repair work. This service tackles structural issues like loose boards, gaps between planks and squeaking, along with surface refinishing. Restoration may include replacing damaged boards and filling gaps before refinishing the surface. Projects requiring restoration cost significantly more due to additional labor and required materials.

Can You Refinish Hardwood Floors Without Sanding?

Chemical refinishing offers a sandless alternative that costs less than traditional methods, but it only works in specific situations. The process uses chemical solutions to remove the old finish without sanding the surface of the wood. The floor must be in good condition with minimal damage to get acceptable results with this process.

Screening and recoating is another sandless option for floors that need only minor touch-ups. According to HomeGuide, screening costs $2 to $5 (CAD 2.82 to CAD 7.05) per square foot, making it the most economical choice when your floors need freshening but don't need to go through the full refinishing process.

Both sandless methods have limitations. They can't remove deep scratches, change the floor's color or address uneven wear patterns. Floors with significant damage will still need traditional sanding and refinishing.

How Long Does It Take to Sand and Refinish Hardwood Floors?

A typical room takes 2 to 5 days to completely refinish. Sanding usually requires 1 full day for an average-sized room, though larger spaces may need additional time. After sanding, it's time for staining and sealing, with each coat of polyurethane needing 24 hours or more to dry properly.

Most professionals apply two to three coats of finish, with drying time between each application extending the project timeline. Water-based polyurethane dries faster than oil-based formulas, potentially reducing the total project time. You'll need to stay off the floors during this curing period to prevent damage to the fresh finish.

How Long Will Wood Floor Resurfacing Last?

Properly refinished hardwood floors typically last 7 to 10 years before needing attention again. This timeframe varies based on foot traffic, maintenance habits and the quality of materials used. High-traffic areas like hallways show wear faster than bedrooms or formal dining rooms.

The finish type affects longevity. Oil-based polyurethane generally lasts longer than water-based formulations, though both provide excellent protection when properly applied. Regular maintenance, including prompt spill cleanup, furniture pads and periodic cleaning, helps maximize your refinishing investment.

Planning Your Floor Refinishing Project

Successful floor refinishing requires advance planning. Clear all furniture from the rooms being refinished before work begins. Some contractors offer furniture moving services for an additional fee.

Plan to stay elsewhere during the project if possible. The noise, dust and fumes make remaining in the house uncomfortable. If staying home is necessary, contractors can work on one section at a time.

Choose a qualified flooring professional with specific hardwood refinishing experience. Check references, verify licensing and insurance and review photos of completed projects. Getting multiple quotes helps ensure fair pricing.
