The same small crew stays with your project from the first measurement to the last coat, no rotating subcontractors. We price everything line by line and keep dust down with vacuum-assisted equipment, though no setup removes it completely; edges and corners can leave a little fine residue. We finish with Bona and Loba products that are kid- and pet-safe once cured, and we’ll come measure your Winnetka home for a free estimate within 24 hours.

17+ Years of Hands-On Hardwood Experience

We’ve spent over 17 years working hands-on with hardwood, learning what each type of floor needs before problems show up. That long-term experience helps us choose the right approach, whether we’re looking at an original strip oak floor or a newer engineered plank.

Owner-Led From Start to Finish

Dan (Donatas) and the same small crew handle your project from the first walkthrough to the last detail. There’s no rotating subcontractors and no handoff between stages, so you always know who’s on site and your questions get answered directly.

Tailored for Winnetka Homes

Winnetka’s housing mix runs from early 1900s houses to newer custom builds and condos, and we plan around what each one actually needs. That means factoring in lake-effect humidity, dry winter heat and how your household really uses its rooms, not a one-size-fits-all approach.

Complex Projects Planned, Not Improvised

Tight hallways, concrete subfloors, custom color blends and tricky room transitions all call for a real plan. Before we start any Winnetka project, we work out access, prep, materials and sequencing in advance, so there’s less guesswork later and fewer surprises along the way.

GREENGUARD-Certified, Pet-Safe Finishes

We finish floors with low-VOC, water-based products only, including Bona and Loba products. Bona carries GREENGUARD Gold certification and Loba is EMICODE EC1 certified, giving Winnetka families and pets a finish that’s safe once fully cured, on solid or engineered hardwood alike.

Hardwood Flooring Services From Your Winnetka, IL Contractor

Big Bro Hardwood wood floor contractor offers all kinds of professional flooring services in Winnetka:

Hardwood floor installation in progress

Hardwood Floor Installation in Winnetka

We lay solid and engineered wood floors, prefinished or finished on site, in red oak, white oak, maple and more. Before anything goes down we check the subfloor for flatness and moisture and let the wood acclimate, so it stays tight through Winnetka's cold winters and humid summers.
Sanding and refinishing a hardwood floor

Dustless Sanding & Refinishing in Winnetka

Vacuum-assisted equipment keeps dust down while we take tired boards back to bare wood. Fresh color and new coats of finish bring dull, scratched or greyed floors back to life for a fraction of replacement cost, starting from $3/sq ft.
Worker staining a hardwood floor

Hardwood Floor Staining in Winnetka

We test color right on your own floor before anything is final, so you see the true tone on your actual wood, not a sample board. Natural, Jacobean, white-washed and grey tones are all on the table.
Hardwood floor repair

Hardwood Floor Repair in Winnetka

Water damage, rotted boards, deep scratches, dents and the seasonal gaps common in older Winnetka homes all get fixed. We match species, grade and board width so the patch disappears into the surrounding floor.
Worker installing hardwood stairs

Stair Installation & Refinishing in Winnetka

Treads, risers, railings and newel posts, built or renewed to match your floors. It's the hand-work that ties the steps to the rest of the house, done by the same crew that handles the rest of your project.

Hardwood Flooring Built for Winnetka, Illinois Homes

Winnetka's housing stock and climate change what works on the floors; here is how our specialists adapt the work by home type and condition.

1

Older Homes and Estate-Era Houses

Many Winnetka homes date back to the early 1900s through the 1930s, often with diagonal pine or mixed-species subfloors under the original red oak or maple. Those boards can usually be restored and recoated rather than torn out, even after years hidden under carpet. For homes built before 1978, we follow EPA lead-safe (RRP) rules during any dust-controlled work.

2

Additions and Rehabbed Spaces

When a Winnetka home gets a kitchen addition or a rehabbed family room, the new wood has to match the old in species, grade and board width. We hand-pick boards and lay patches so the seam between original and new flooring disappears, not just blends.

3

Newer Custom Construction

Winnetka’s newer custom homes, especially those built since the late 1990s, often call for wide-plank engineered or prefinished hardwood. Before any work begins, we check subfloor flatness and moisture levels so seasonal movement does not open gaps later.

4

Condos and Lower-Level Spaces

Homes near the lake and ravine areas, along with condos and basement-level rooms on concrete slabs, deal with higher moisture swings. Engineered hardwood with a glue-down or floating system handles that movement better than solid wood in these spots.

5

Lake-Effect Humidity Through the Seasons

Winnetka’s dry forced-air winters and humid summers push wood to expand and contract all year. We acclimate wood on site and recommend keeping rooms between 30-50% humidity to head off cupping, gapping and crowning before they start.

In many Winnetka homes the original wood is worth saving rather than tearing out, but the only way to know for sure is for a professional hardwood flooring contractor to look at your subfloor and the condition of the boards up close.

If you want your floors to look awesome, have it done reliably and have very fair pricing, contact BigBroHardwood. We had our floors redone prior to moving in, the former owners didn't take care of the floors at all and now they look brand new!

We hired Donatas to refinish hardwood floors in our 56-year-old Darien house last week and we are very pleased with the results. We dreaded the project because we had to shuffle furniture into other rooms and because of my preconceived notion that the entire house would be covered in sawdust. Well, I have to say it was nowhere near as bad as anticipated! Donatas sealed off adjacent areas and kept the dust down to a minimum, vacuuming up at the end of each day. We were very impressed with his attention to detail and overall work ethic, going out of his way to fix an unexpected issue resulting in a very long day for him. Ours was a week-long project, followed by a five-day curing period and Donatas made it as painless as possible for us. We feel very comfortable giving Big Bro Hardwood and Donatas in particular a five-star review and highly recommend them!

Dan transformed our 50 year old floors. They now shine as if they are brand new! We love the color of stain and the commercial finish he offered. Knowing we have a large dog this was a perfect choice and feel it is a great value. Again we are so happy with the results. Dan was prompt, professional and accommodating.

We would highly recommend Big Bro Hardwood!

We hired Dan after talking to 2 other companies and couldn’t be happier!!
He did a fantastic job, he showed up on time and his price was very reasonable.
He sanded and stained our 2nd story oak floors from golden oak color to a beautiful Jacobean stain. I really wish I had gotten “before & after” pictures. Our floors look absolutely beautiful and unlike the crew who did our 1st floor, Dan was very careful not to get ANY dark stain splatters on our white trim.
His hard work is impeccable and he’s a great credit to his craft!
I highly recommend him.

Couldn’t be happier with the job Big Bro did. The previous owners of our home installed bright red maple (who knows why), and I’ve wanted to change it forever. Maple is hard to work with, and Dan did a beautiful job. He worked with us on breaking up the project into two parts to inconvenience us the least, and was always on time and cleaned up. The project timeline went exactly as expected (a rarity these days). While refinishing floors is a hassle by default, Dan made it as painless as possible. Check out our before and after of one room for the big difference (still needs paint!)

Who actually shows up to do the work at my Winnetka home?

Dan (Donatas) is on every job, and the same small crew stays with your project from the first walkthrough to the final detail. We don’t bring in rotating subcontractors, so the people measuring your Winnetka floors are the same ones finishing them.
