Before a single board goes down, we verify subfloor flatness and moisture levels and acclimate the wood on site, so your floor stays tight through Northbrook's cold winters and humid summers.

Hardwood Flooring Built for Northbrook Homes

Northbrook's mix of mid-century ranches, split-levels, and newer custom builds means the right flooring approach depends heavily on when and how your home was constructed. Here is how we adapt by home type and condition:

1

1950s-1970s ranch and split-level homes: These are the most common homes in Northbrook. Most have original red oak strip flooring that can be sanded and refinished rather than replaced. For any home built before 1978, we follow EPA Lead RRP protocols – proper containment, HEPA vacuuming, and clearance verification.

2

Partial slab sections in split-levels and lower levels: Ranch and split-level layouts often mix wood-framed areas with slab sections. On concrete, we use glue-down or floating engineered systems and address moisture before anything goes down.

3

Teardown replacements and custom new construction: Northbrook sees steady infill and teardown rebuilds. These homes typically use wide-plank engineered oak over advanced subfloor systems. We check subfloor flatness and moisture levels before installation so seasonal movement does not open gaps later.

4

Additions and remodels: When a room is added or a layout changes, we match species, grade, and board width so the new wood blends into the existing floor without looking patched.

5

North Shore humidity swings: Cold, dry winters from forced-air heat followed by warm, humid summers put real stress on hardwood. We acclimate wood on site and recommend keeping indoor humidity between 30-50% year-round to prevent cupping, gapping, and crowning.

In many Northbrook homes the original hardwood is worth saving rather than pulling out - but the only way to know for certain is to look at the subfloor and the boards up close.

Before & After: See a Recent Northbrook Refinishing Project

A lot of mid-century ranch homes in Northbrook still have their original hardwood floors hiding under years of wear. This one was no different - the boards were scratched, scuffed and had lost their finish almost completely. We sanded them back to bare wood, repaired the damaged sections and refinished everything in place. Same floor, no replacement. Take a look at the before and after photos and judge the results for yourself.

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

Can you refinish the original oak floors in my Northbrook ranch or split-level home?

Absolutely. Many mid-century ranch and split-level homes in Northbrook have original red oak strip flooring that has plenty of life left in it. We assess the wood thickness before we touch anything, and if the boards can take another sanding, refinishing is almost always the smarter call over replacement. We use vacuum-assisted dustless sanding and Bona or Loba low-VOC finishes that are safe for kids and pets once cured. Refinishing starts at $3 per square foot.

My Northbrook home was built in the 1950s. Do you take any special precautions?

Yes. Homes built before 1978 may have lead-based paint on baseboards, trim, or under old floor finishes. We are EPA Lead RRP certified, so we follow full containment, HEPA vacuum protocols, and post-work verification on every pre-1978 project in Northbrook. We will let you know upfront if your home falls into that category and walk you through exactly what that process looks like before any work begins.

Does Northbrook's climate affect hardwood floors, and how do you handle it?

It really does. The humid continental climate here means wide seasonal swings, cold dry winters and warm humid summers, and those shifts cause wood to expand and contract. We acclimate every board on site before installation and recommend keeping indoor humidity between 30-50% year-round. For lower-level spaces in ranch homes that sit on slab, we check moisture carefully and use engineered wood or glue-down methods where solid hardwood would not be stable long-term.

Do you install hardwood in the newer custom and teardown homes being built in Northbrook?

We do. A lot of the newer construction and teardown-replacement homes in Northbrook use engineered wide-plank oak over advanced subfloor systems, and that is work we handle regularly alongside classic nail-down installs in older homes. We check subfloor flatness and moisture levels before any installation, follow NWFA Technical Guidelines, and keep the same small crew on your project from start to finish. Contact us for a free in-home estimate within 24 hours.

How much does a hardwood floor project cost?

It depends mostly on square footage, the condition of the floors, and whether you’re refinishing or installing new. Refinishing starts around $3 per square foot; new installation costs more because of materials. You get an itemized price at the free in-home estimate, and you can get a rough number first with our online cost calculator.

How long does it take, and can we stay in the house during the work?

Most refinishing projects take 2–5 days, depending on size, stain, and number of finish coats. You can usually stay home – we seal off work areas and keep sanding dust to a minimum with vacuum-assisted equipment – but you’ll need to keep off the floors while the finish cures (water-based finishes are walkable sooner than oil-based). We give you a day-by-day plan before we start.

Do you require a deposit, and how does payment work?

For most projects, we take a deposit to cover materials and lock in your dates, with the balance due once the work is finished and you’re happy with it. We put the exact terms in writing at the estimate, so there are no surprises.
