How Our Hardwood Flooring Contractor Adapts to Oak Brook, IL Homes

Oak Brook'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

Mid-Century and 1970s Custom Homes

Most Oak Brook homes date from 1970 to 1989, and many still carry their original narrow-strip or plank oak. That solid wood can almost always be restored and recoated rather than torn out, as long as the boards are not cupped through or rotted from long-term water exposure.

2

Additions and Remodeled Spaces

Custom brick Colonials, split-levels and French Provincial estates in Oak Brook often get kitchen or family room additions over the years. We match species, grade and board width so new patches blend into the old floor, with no visible seam where the two meet.

3

Large Custom and Contemporary Homes

Bigger luxury properties around Oak Brook sometimes have higher-grade maple, walnut or ash alongside oak. These floors need careful subfloor checks before any work, since wood joists with plywood or dimensional-board subfloors behave differently than a slab.

4

Additions and Lower Levels on Slab

Concrete slabs show up under additions, lower-level living space, ranches and some attached housing. We check moisture conditions before any work on these sections, since a slab holds dampness differently than a wood subfloor and can affect how the floor settles.

5

Oak Brook's Humid Continental Climate

Cold, dry winters and humid summers push wood to expand and contract all year. We acclimate the wood on site and recommend keeping rooms at 30-50% humidity to prevent cupping, gapping and crowning as the seasons change.

In many Oak Brook 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!)

Frequently Asked Questions

Does Big Bro Hardwood follow lead-safe rules in older Oak Brook homes?

Oak Brook has a good number of homes built before 1970, and some of the custom brick Colonials and split-levels date back further still. When we work on floors in these older homes, we follow EPA lead-safe (RRP) rules, including proper containment and cleanup. Original solid oak in these homes is often worth bringing back to life rather than tearing out and replacing.

Can you work on a condo or townhome in Oak Brook without disrupting neighbors?

Yes. For condos and townhomes we provide a certificate of insurance, follow building rules and quiet hours, and protect shared hallways and entryways while we work. We’re fully insured, and the same small crew handles the job from start to finish, so there’s one point of contact for your building manager or HOA the whole way through.

Do you serve areas near Oak Brook, or just Oak Brook itself?

We work throughout Oak Brook and the surrounding area, including Western Springs, Hinsdale, Willowbrook, Downers Grove, Elmhurst and other nearby suburbs. Wherever the job is, it’s the same crew and the same approach, matched to whatever that home’s floors and subfloor need.

What determines the cost of a hardwood flooring project in Oak Brook?

Price depends on the size of the area, the condition of the existing boards, the scope of the work, and building access, since a detached home in Oak Brook prices differently than a condo with elevator logistics. Our work starts from $3/sq ft, and you get an itemized quote after we see the floors in person. Get a rough first number with our cost calculator before the visit.

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

The owner is on every job, start to finish, with one small crew and no rotating subcontractors. That means the person who measures your floors on day one is the same person overseeing the last coat, which keeps quality and communication consistent across the whole project.
