(630) 418 4139Big Bro Hardwood is an employee-owned hardwood flooring company serving Wilmette and the surrounding North Shore 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 – restoring original red oak strip floors in Wilmette’s prewar brick colonials and Tudors, pulling up carpet in mid-century ranches and split-levels to reveal hardwood worth saving, and fitting engineered plank in finished basements where moisture calls for a smarter approach.








The same small crew handles every Wilmette 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 come out for a free estimate within 24 hours.

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.

Finish Options Matched to Daily Use
Choosing the right finish is about more than gloss level.

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.

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.
1
Call or send the form, tell us about your floors, and we’ll set a time to come look.
2
We measure, check the wood and subfloor, talk through color and options, and leave you an itemized estimate.
3
Our crew handles prep, sanding, install, stain, and finish on a dust-controlled setup, cleaning up daily.
4
We do a final walkthrough, go over care and timing, and stand behind the work.
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.

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.
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.
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.
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.
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.
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.
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.
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.
