Free In-Home Estimate Within 24 Hours

We come to your Wilmette home, walk the floors, check subfloor conditions, and talk through exactly what you want. Within 24 hours you receive a written estimate based on what we actually found, not a rough guess from a phone call.

Serving Wilmette and Nearby Suburbs

Big Bro Hardwood has been working with homeowners across Wilmette and 30-plus surrounding suburbs since 2008. We’re not a franchise passing jobs to whoever is available. It’s the same experienced crew on every project, which means consistent craftsmanship and straightforward communication from the first visit to the final coat.

Finish Options Matched to Daily Use

Choosing the right finish is about more than gloss level. We look at your wood species, foot traffic, whether you have kids or pets, and how sensitive your household is to odors and drying time before we make a recommendation. Every finish recommendation comes with practical guidance on when to bring furniture back in, how to clean your floors, and how to protect them for years ahead.

We install solid and engineered hardwood - red oak, white oak, maple, and more - in both prefinished and site-finished options. Before a single board goes down, we check subfloor flatness, test for moisture, and acclimate the wood on site so your floor stays tight through Wilmette's humid summers and dry winter months.

Hardwood Flooring Built for Wilmette Homes

Wilmette's mix of prewar colonials, mid-century ranches, and newer custom rebuilds means no two floors are quite the same - here is how we adapt our work to what each home actually needs.

1

Prewar and Early Postwar Homes

Many Wilmette homes from the 1920s through the 1940s have original red oak strip floors under decades of finish. We sand them back carefully, check for loose boards and nail pops, and refinish with low-VOC Bona or Loba coats. Because most of these homes predate 1978, we follow EPA Lead RRP protocols on every job – proper containment, HEPA vacuuming, and clearance verification before we leave.

2

Mid-Century Ranches and Split-Levels

The 1950s and 1960s ranches common throughout Wilmette often mix hardwood in living areas with carpet over plywood in bedrooms. We match species and stain when uncovering those hidden boards, and we check subfloor flatness and moisture before fastening anything new down.

3

Additions and Rehabs

Blending new wood into an older floor is one of the harder things we do. We source boards close in width and grain, feather the sanding passes across the seam, and stain the whole floor together so the addition does not look like a patch.

4

Finished Basements

Wilmette basements can see seasonal seepage and high humidity, so we moisture-test the slab before recommending any product. Floating or glue-down engineered hardwood is usually the right call below grade, with a vapor retarder underneath.

5

Lake-Effect Humidity Swings

Proximity to Lake Michigan means humidity can shift fast between seasons. We acclimate every board on site before installation and ask homeowners to keep indoor humidity between 30-50% year-round to protect the floor long after we are gone.

In many Wilmette 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.

Before & After: See a Recent Wilmette Refinishing Project

A homeowner in Wilmette reached out about the original hardwood in their 1950s brick ranch - the boards were worn through in the high-traffic areas, scratched up, and had lost any sheen they once had. We sanded them back to bare wood, repaired the damage, and refinished them from scratch. Same floors, no replacement. Take a look at the before and after photos below and judge the results for yourself.

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!)

Frequently Asked Questions

Most Wilmette homes were built in the 1940s-1960s. Does that affect my hardwood floors?

It does, and in mostly good ways. Those mid-century homes often have original red oak strip flooring under decades of carpet or old finish – solid wood that can typically be sanded and refinished several more times. We check board thickness and subfloor condition before recommending anything. Because many of these homes predate 1978, we follow EPA Lead RRP protocols – proper containment, HEPA vacuuming, and verification – so your family stays safe throughout the work.

Wilmette winters are brutal and summers are humid. How does that affect hardwood floors?

Lake Michigan proximity means your floors face real humidity swings – dry, freezing winters and warm, wet summers. Wood moves with those changes, so we always acclimate boards on-site before installation and recommend keeping indoor humidity between 30-50% year-round. A whole-home humidifier in winter helps a lot. We follow NWFA guidelines on fastening and expansion gaps specifically because Wilmette’s climate puts more stress on flooring than most people expect.

I have a finished basement in my Wilmette ranch. Can I install hardwood down there?

Solid hardwood below grade is risky in Wilmette basements – seasonal seepage and high humidity are common in homes from this era. We recommend engineered hardwood for finished basement spaces. It handles moisture variation far better than solid wood, still looks beautiful, and can be floated over the slab without adhesive in most cases. We always run moisture tests first. If readings are elevated, we discuss vapor retarder options before anything gets installed.

My 1920s Tudor near the lakefront has parquet and border details in the formal rooms. Can those be matched or repaired?

Parquet and decorative borders in those older Wilmette homes are worth preserving when possible. We assess each section individually – loose tiles, missing pieces, and worn finish are all repairable more often than people think. Where replacement pieces are needed, we source species and patterns that match closely. Spot repair combined with a full refinish is usually the most cost-effective path and brings the whole floor back to one consistent look.

What does hardwood floor refinishing cost in Wilmette, and how do I get a ballpark figure?

Refinishing starts at $3 per square foot. The final number depends on floor condition, square footage, number of coats, and whether staining is involved. For a quick estimate before we visit, try our cost calculator. For homes under 1,200 square feet we offer flat-rate pricing. Every in-home estimate is free, itemized line by line, and scheduled within 24 hours. First-time clients also receive 10% off when booking naturally finished floors.

How do I know whether to refinish my existing floors or replace them entirely?

We look at three things: board thickness, structural condition, and what you want the finished floor to look like. Most solid hardwood can be sanded 3-5 times over its life, so if there’s enough wood left and no serious damage, refinishing is almost always the smarter investment. Replacement makes sense when boards are cupped beyond repair, heavily damaged, or too thin to sand safely. We give you an honest answer at the free estimate – no upselling.

How long does the work take, and do we need to leave the house?

A typical refinishing job in a Wilmette home runs 2-4 days depending on square footage and finish coats. Installation projects vary by scope. You don’t have to leave, but finish fumes can be noticeable for several hours after each coat, so many families step out during application. We use low-VOC Bona and Loba finishes that are kid- and pet-safe once fully cured. We’ll walk you through the exact timeline before we start so there are no surprises.

What does your dust control actually look like, and is there a warranty on the work?

We use vacuum-assisted sanding equipment that captures 95% or more of dust at the source – walls, vents, and furniture stay clean. The same small crew handles your project start to finish; we never hand jobs off to rotating subcontractors. Every job is backed by a workmanship warranty covering craftsmanship faults, plus a 100% Satisfaction Guarantee. If something isn’t right, we come back and fix it. Emergency repairs are available within 48 hours for existing clients.
