Big Bro Hardwood is a hardwood floor refinishing company working in Oak Brook, IL, run by its owner. We sand and refinish solid and engineered wood floors in Oak Brook homes, bringing back floors that are dull, scratched, gray or water-marked. Oak Brook grew largely through the Del Webb Corporation from the 1960s into the late 1970s, so many houses still carry their original oak under old carpet or tile.

Wood Floor Refinishing Across Oak Brook Subdivisions

Our wood floor refinishing covers every corner of Oak Brook, since the village is made up mostly of residential subdivisions instead of a handful of named neighborhoods.

Hardwood Floor Refinishing Services Cost in Oak Brook, Illinois

Refinish, Recoat, Repair Boards or Replace?

Most floors can be saved with hardwood floor repair and refinishing. If you’re deciding whether to refinish or replace hardwood floors, keeping your floor is usually the more affordable choice: installation labor alone runs $3.00–$9.50/sq ft, before the new wood and $1–$3/sq ft to remove the old floor.

What You See on Your Floor	What It Usually Needs	How Often
Dull finish or light scratches, no bare or gray wood	Buff & recoat (sandless), also called screen and recoat	Every 3 to 7 years
Deep scratches, gray or worn spots, or you want a new color	Full sanding down to bare wood and new finish coats	Every 7 to 10 years
A few cracked or loose boards, or marks that soaked in deep	Board replacement as part of the refinishing job	As needed
Nail heads or tongues showing, boards cupped through or rotted	A new hardwood flooring installation; we tell you honestly when a floor can’t take another sand	Not applicable

Hardwood Floor Sanding in Oak Brook Homes Across the Decades

Oak Brook homes range from older subdivision houses to newer construction, and each era can add a step to a refinishing job. We check the finish, the floor type and the wear layer before quoting.

Pre-1978 Construction. With a median year built of 1979, many Oak Brook homes fall right at or before the 1978 lead cutoff. In those houses we follow EPA RRP lead-safe practices, with containment and HEPA cleanup, before any sanding starts.
Few Pre-1940 Houses. Only 0.4% of Oak Brook’s housing dates before 1940, so old wax or shellac finishes under the floor are rare here. When we do find one, it needs full removal before a new finish can bond, which adds a step to the job.
Newer Construction Since 2010. About 7.2% of homes were built in 2010 or later, and these often have factory-finished aluminum-oxide floors. That coating can’t simply be recoated like a site-finished floor, so we check the finish type before quoting.
Attached and Townhome Units. Attached single-family units make up 7.7% of Oak Brook’s housing stock, and many of these carry engineered wood floors. We measure the wear layer first, since engineered boards can only be sanded if that layer is thick enough.

Our Professional Hardwood Floor Refinishing Process and Timeline in Oak Brook

You can usually stay home during the work. Up to about 300 sq ft takes 1 to 2 days, and a one-day refinish may be possible. About 1,000 sq ft takes 3 to 4 days, since each coat must dry before the next.

Before Day 1: Estimate and Inspection

We measure the floor, check wear, damage, loose boards and squeaks, and go over color, sheen and what’s included. Buying a home? We can do a free estimate before you close, so the floors are done before the furniture moves in.
Day 1: Protection and Rough Sanding

We cover walls, cabinets and transitions and run an Atomic Dust Containment System with HEPA-filtered Festool vacuums, which captures 95% or more of the dust at the source, though edges and corners always leave some fine residue. Professional floor sanding starts in a controlled grit sequence across the field. Sanding is loud, so plan work-from-home days around it.
Day 2: Fine Sanding and Repairs

We detail edges and corners so the whole room looks even, fix damaged boards and small gaps, and clean the surface so color takes evenly.
Day 3: Stain

After hardwood floor sanding, we test stains right on your floor and apply the color you pick. On red oak, lighter browns bring out the red and darker colors show scratches more easily, and a perfect match with older or discontinued wood isn’t always possible. Without a color change, this day goes to finish coats.
Day 4: Finish Coats

We apply 2 coats of finish as standard, or 3 if you choose the extra coat. Our low-VOC water-based finishes give off far fewer fumes than oil-based polyurethane, which often means planning how long to stay out of the house after refinishing. Bona (GREENGUARD Gold) and Loba (EMICODE EC1) products are safe for families and pets once cured.
After the Last Coat: Walkthrough and Moving Back In

We walk the floor with you, do touch-ups and leave care instructions: knowing how to maintain hardwood floors keeps the new finish looking good longer. Light foot traffic is usually fine after about 24 hours, and pets can come back after 24 to 48 hours. Furniture goes back after 3 to 5 days and rugs after 5 to 7 days, because how long polyurethane takes to dry sets the pace for each stage. Put felt pads under furniture legs and lift pieces into place instead of dragging them.

Why Oak Brook Homeowners Choose Big Bro Hardwood as Their Floor Refinishers

Once you approve the quote, we get you on the schedule, usually within two to four weeks depending on our current workload.

Our professional wood floor refinishing crew is led by Dan, the owner, with Valdas (20+ years in hardwood flooring) and Slavek (37 years of stair and finish carpentry). We follow NWFA technical guidelines, our finish carries a 5-year warranty against peeling, and more than 80% of new clients come through referrals.

Subdivision HOA Notices

Subdivision homeowners associations are active across Oak Brook, and many set notice periods or allowed work hours for contractors. We confirm your subdivision’s rules before setting a start date, so there are no surprises on day one.

Wood Type & Condition First

Houses across Oak Brook were built through decades of subdivision development, so species and finish can differ from room to room. We check the wood type and condition before writing any quote, not after.

Pet- & Family-Safe Finish Options

Yards and driveways come standard with most Oak Brook houses, often with dogs, cats and kids tracking through. We pick finishes with controlled odor and tell you exact dry and cure times before work starts.

Driveway Access for the Crew

Driveway access matters for sanding equipment, and most Oak Brook houses are single-family homes with their own driveways. That makes loading our Festool vacuums and gear simple, without hunting for street parking.

Color Samples on Your Floor

Printed charts don’t show how color looks in your own rooms, so we test choices directly on a prepped section of your floor, under daylight and lamp light, matching Oak Brook’s many different subdivision styles.

Few Multi-Unit Buildings

Few homes in Oak Brook sit in attached or multi-unit buildings, so most of our refinishing jobs are standalone houses without shared hallways to protect. When we do work in a townhome, we still cover common areas and coordinate access.

We just had Big Bro Hardwood rip out the existing flooring in 2 rooms, tie into our existing hardwood and then had everything sanded and refinished. We could not be happier with the results. The Big Bro Hardwood team was professional, punctual, and the quality of the work was outstanding. Even the trim work was done with incredible attention to detail. My wife and I highly recommend Big Bro Hardwood to anyone looking to refinish their hardwood floors!

Frequently Asked Questions

Does Oak Brook Require an Inspection After Floor Refinishing?

No. Oak Brook doesn’t require a permit for floor covering work, so no inspection follows either. Once you approve the quote, we schedule the wood floor refinishing directly, with no building department sign-off to wait on.

Do Oak Brook Subdivision HOAs Ask for Proof of Insurance?

Some do. A few subdivision HOAs ask contractors for a certificate of insurance before work begins. We’re fully insured for houses and send that certificate ahead of your start date.

Does Oak Brook Sitting in Two Counties Affect Floor Sanding Work?

Not for the work itself. Oak Brook spans both DuPage and Cook counties, but our hardwood floor sanding process, dust control and finish choices stay the same on either side of the line.
