Certified Pet- & Family-Safe Finishes
Repairs Before Refinishing
15,000+ Hands-On Hours
Big Bro Hardwood is an owner-operated hardwood flooring company working in Darien and nearby suburbs. We install, sand, stain, refinish, and repair solid and engineered wood floors, starting around $3 a square foot. In 17+ years, we’ve done 500+ floors around the area, including bringing 1970s oak back to life in Darien’s ranch and split-level homes, and matching new boards into older houses near Hinsbrook and Farmingdale where additions and sunken rooms meet the original wood.
The same small crew works your Darien floors from the first measurement to the last coat, no rotating subcontractors. We price everything line by line, keep dust down with vacuum-assisted equipment (it won’t eliminate dust and odors entirely, and edges and corners can leave a little fine residue), and finish with Bona and Loba products that are kid- and pet-safe once cured. We’ll come measure and give you a free estimate within 24 hours.
17+ Years of Hands-On Hardwood Experience
Seventeen-plus years of hands-on work means we recognize what a Darien floor needs before we start, whether it is an original oak floor from the 1970s or a newer engineered plank in a condo. That practical experience keeps surprises off your project.
On-Time, No-Stress Projects
Our crew keeps a steady schedule, treats your home with care, and answers your questions along the way. From the first visit to the final walk-through, Darien homeowners get clear communication and a process that never feels rushed or confusing.
GREENGUARD-Certified, Pet-Safe Finishes
We finish floors with low-VOC, water-based Bona and Loba products. Bona carries GREENGUARD Gold and Loba carries EMICODE EC1 certification, giving Darien families and pets a trusted, cured finish on both engineered and solid hardwood.
Premium Results From $3/sq ft
A beautiful floor shouldn’t cost a fortune. We start Darien projects from $3/sq ft without cutting corners on materials or craftsmanship. Curious what your room might run? Try our hardwood floor cost calculator for a quick ballpark number before your estimate.
Tailored for Darien Homes
Darien’s mix of older ranches, split-levels and newer builds each bring different flooring needs, from original strip oak to concrete slabs under townhomes. We plan around seasonal humidity swings and dry winter heat so your floors stay stable through every DuPage County season.
Finish Options Matched to Daily Use
Wood type, foot traffic, kids, pets and odor sensitivity all shape which Bona or Loba system makes sense for your home. We walk you through realistic cure times so you know exactly when furniture, rugs and daily life can return to the room.

Darien'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
1970s and 1980s Ranches and Split-Levels
Many Darien homes from this era have original oak under carpet or vinyl in living rooms and bedrooms. That wood can almost always be restored and recoated instead of torn out, even after decades covered up. We check the boards up close before deciding, since a full tear-out is rarely the first option.
2
Split-Level Transitions and Additions
Ranch and split-level layouts in Darien often mix hardwood with carpet, vinyl and tile, with uneven spots around additions, kitchens and sunken rooms. We match species, grade and board width so new wood blends into the old, and patches disappear instead of leaving a visible seam across the room.
3
1990s and Later Infill Homes
Newer Darien builds lean toward wide-plank engineered and prefinished hardwood over plywood subfloors. Before any work begins, we check the subfloor for flatness and moisture, since skipping that step is what leads to gaps or ridges once the seasons turn.
4
Townhomes and Condos on Slab
Attached townhomes and condos around Darien vary building by building, some on concrete slabs, others with engineered floor systems. We plan glue-down or floating setups to match what’s actually underfoot, follow any HOA scheduling rules, and use low-VOC finishes throughout.
5
Pre-1978 Homes and Lead-Safe Prep
A portion of Darien’s homes predate 1978, which means older finishes may need EPA lead-safe (RRP) containment before any wood is disturbed. We take the same careful approach whether we’re uncovering old oak or working around existing trim.
6
Humidity and Seasonal Movement
Darien’s cold, dry winters and humid summers push wood to expand and contract all year. We acclimate material on site and recommend keeping rooms between 30-50% humidity to help prevent cupping, gapping and crowning long after we’ve left.
In many Darien 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.

Our team worked in these Darien homes with a red oak dining room after water damage, a warm natural floor, white oak in a light white wash, and Classic Grey with a matching staircase.
This new Darien home got white oak hardwood in a light white wash under Loba 2K Duo. Our wood flooring experts ran it across the great room, the kitchen and the main level.
Classic Grey under Loba 2K Duo runs through the living room, the great room and the kitchen of this Darien home. Our expert hardwood flooring crew matched the stair treads, with white risers and new black iron balusters.

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!Read more

Yes. We’re based nearby and serve Darien along with Willowbrook, Burr Ridge, Hinsdale, Downers Grove, Western Springs and other nearby suburbs. If your Darien home sits near any of those towns, the same crew and the same pricing apply. We cover 35 cities and suburbs across the area in total, so distance is rarely a problem for scheduling your project.
Price depends on square footage, the condition of your existing boards, and the scope of work, plus building access for condos with elevators or limited parking. Projects start from $3/sq ft, and the exact number comes from a free in-home estimate, not a phone guess. For a rough idea before we visit, try our cost calculator.
Most Darien projects start about 2 to 4 weeks after the signed agreement, depending on our current schedule. Shorter jobs sometimes fit in sooner without the usual wait. We set the actual start date once we’ve seen your floors in person and agreed on scope, so you know what to expect before any work begins.
We come to your Darien home, walk the rooms, check the subfloor and existing boards, and answer your questions in person. Photos can give a rough preliminary number ahead of time, but the exact price always comes from this on-site visit. You’ll hear back with a free estimate within 24 hours of our visit.
The same small crew handles your project start to finish, with the owner on every job. There are no rotating subcontractors coming in and out of your Darien home. That’s true whether you’re in an original ranch near Hinsbrook or a newer build out toward Farmingdale, one accountable team the whole way through.
Tell us about your floors and we'll get back to you within 24 hours.
