15,000+ Hands-On Hours
Big Bro Hardwood is an employee-owned hardwood flooring company serving Buffalo Grove and the surrounding suburbs. We install, sand, stain, refinish, and repair solid and engineered wood floors, starting around $3 a square foot. In 17+ years, we have completed 500+ floors across the area – pulling up carpet in 1970s split-levels and ranches to uncover strip oak worth saving, upgrading prefinished floors in 1990s colonials to wider-plank site-finished hardwood, and handling glue-down engineered installs in Buffalo Grove townhomes and condos where slab-on-grade is the norm.
The same small crew handles every Buffalo Grove job from the first measurement to the last coat – no rotating subcontractors, ever. We give you a clear, line-by-line estimate, control sanding dust with vacuum-assisted equipment, and finish with Bona and Loba products that are kid- and pet-safe once cured. Call or email us and we will have a free estimate to you within 24 hours.
Premium Results From $3/sq ft
Beautiful hardwood floors in Buffalo Grove don’t have to come with an overwhelming price. Our refinishing work starts at just $3, and installation pricing is straightforward with no hidden markups. Use our hardwood floor cost calculator to get a quick sense of your project before we even step through the door. We also provide free in-home estimates within 24 hours.
17+ Years of Hands-On Hardwood Experience
Since 2008, our crew has worked through more than 500 projects and logged over 15,000 hours on real hardwood floors. We’ve handled everything from original strip oak in older split-levels to wide-plank engineered installs in newer Buffalo Grove colonials. That depth of experience means we spot subfloor issues, moisture concerns, and finish problems before they become costly surprises.
Finish Options Matched to Daily Use
We don’t hand every household the same finish recommendation. Before we suggest a product, we ask about kids, pets, odor sensitivity, and how much daily traffic the space takes. Then we match a Bona or Loba system to those real conditions. We also walk you through cure timelines, cleaning routines, and when it’s safe to bring furniture and rugs back in.
Floors and Stairs Under One Scope
We handle installation, sanding and refinishing, staining, repair, and stair work as one coordinated project. That matters when you want treads, risers, and main floor boards to match in species, stain, and sheen. One crew, one plan, one consistent result from the entryway all the way up the staircase.
Complex Projects Planned, Not Improvised
Buffalo Grove homes built over basements or with slab-on-grade foundations each call for a different approach. We check subfloor flatness and moisture levels before any material goes down, and we map out the full sequence of prep, installation, and finishing before work begins. Transitions, moisture mitigation, glue-down systems, custom stain blends – none of it gets figured out on the fly.
Dustless Sanding Technology
Our vacuum-assisted sanding equipment captures 95% or more of dust at the source, so it doesn’t settle into your vents, furniture, or air. For families in Buffalo Grove with young kids, pets, or anyone sensitive to airborne particles, that’s a real difference in how livable your home stays during the project. Cleaner process, better air, same great floor.
From split-levels in established subdivisions to newer move-up homes near the Town Center, we handle every hardwood flooring need Buffalo Grove homeowners run into.
We’re a hardwood floor company based in the Buffalo Grove area, with 17+ years of hands-on experience in hardwood floor installation, floor refinishing, staining, and repair services.

Buffalo Grove's housing stock spans several distinct eras, and the local climate adds real seasonal stress to any wood floor. Here is how we adjust our approach depending on what we find in your home.
1
1960s-1980s Split-Levels and Ranches
Many Buffalo Grove neighborhoods grew up during this era, and these homes often have original strip oak under carpet or old vinyl. The plywood subfloors over 16-inch joists are well suited for nail-down solid or engineered hardwood. We check flatness and moisture before we commit to any fastening method, because a floor that moves or flexes will show it within a year.
2
1990s-2000s Subdivision Homes
Homes from this period were frequently built with prefinished oak and carpet. Owners often want to upgrade to wider-plank engineered hardwood or a site-finished look with a custom stain. We assess the existing subfloor condition first, then recommend the system that fits the structure and your goals.
3
Townhomes and Condos on Concrete Slab
Several townhouse and condo developments in Buffalo Grove sit on slab-on-grade foundations. Solid hardwood is not the right fit here. We use glue-down or floating engineered systems with proper moisture mitigation beneath, and we coordinate scheduling around HOA requirements to keep the process straightforward for you.
4
Basement Moisture and Subfloor Stability
Most single-family homes in Buffalo Grove are built over full or partial basements. That is generally good news for hardwood, but basement humidity can travel upward and cause cupping if the subfloor is not properly air-sealed and insulated. We test moisture levels at the subfloor before any installation begins, not after.
5
Buffalo Grove's Seasonal Humidity Swings
Winters here are dry and cold, summers are warm and humid, and hardwood reacts to every shift. We acclimate wood on site before installation and ask every client to keep indoor humidity between 30-50% year-round. That one habit does more to protect a hardwood floor than any finish or species choice.
In many Buffalo Grove homes the original wood is worth saving rather than replacing - the only way to know is to look at the subfloor and boards up close.

We do a final walkthrough, go over care and timing, and stand behind the work.
This one speaks for itself. A homeowner in Buffalo Grove reached out about floors in a 1970s split-level that had taken years of wear - deep scratches, scuffs, and a finish so dull the wood had lost all its character. We sanded them back to bare wood, repaired the damaged boards, and refinished everything in place. Same floors, no replacement. Take a look at the before and after and judge the results for yourself.

It really does. Buffalo Grove gets humid summers and very dry winters, which means your floors expand and contract with the seasons. We acclimate every board on site before installation and always leave proper expansion gaps around the perimeter. We also recommend keeping indoor humidity between 30-50% year-round – a whole-home humidifier in winter makes a big difference in preventing gaps, cupping, or squeaks.
Almost always, yes. Most 1970s Buffalo Grove homes have solid oak strip floors that can be sanded and refinished multiple times. We check the remaining wood thickness before we commit to anything. If there is enough material left, refinishing costs far less than replacement and the results are genuinely beautiful. We will tell you honestly if the boards are too thin or too damaged to save.
Yes, but the approach is different. Solid hardwood nailed into concrete is not a good idea, but engineered hardwood glued down or floated over a slab works very well. We check moisture levels in the concrete first, because slab moisture is a real concern in the area. With the right product and proper moisture mitigation, you can have a beautiful hardwood floor in a condo or townhome.
Basement moisture is the main thing to watch. Wood-frame subfloors over basements can absorb humidity from below, which leads to cupping or movement in the hardwood above. We check subfloor moisture and flatness before every installation. Air-sealing the subfloor and keeping the basement properly conditioned goes a long way. We follow NWFA guidelines on moisture control so your floors stay stable for years.
Refinishing starts at $3 per square foot, and we offer a flat rate for homes under 1,200 square feet. Installation pricing depends on the wood species, board width, and subfloor condition. Our cost calculator gives you a quick ballpark before we ever visit. We also provide free in-home estimates within 24 hours, with itemized line-by-line quotes so you know exactly what you are paying for.
If the wood is solid, structurally sound, and has enough thickness left after previous sandings, refinishing is almost always the smarter move. It costs less, takes less time, and keeps the character of the original floor. Replacement makes sense when boards are severely cupped, cracked beyond repair, or simply too thin to sand again. We inspect your floors during the free estimate and give you our honest recommendation either way.
Refinishing a typical Buffalo Grove home usually takes two to three days, including drying time between coats. Installation projects vary by square footage and subfloor prep needed. You do not have to leave, but foot traffic on the freshly coated areas needs to stay off until the finish cures. We walk you through the timeline before we start so you can plan around it comfortably.
Our vacuum-assisted equipment captures 95% or more of dust at the source, so your home stays remarkably clean compared to traditional sanding. We use Bona and Loba finishes, which are low-VOC and safe for kids and pets once fully cured. We let you know exactly when it is safe to bring everyone back in. No guessing, no surprises.
