Big Bro Hardwood is a hardwood floor refinishing company working in Naperville, IL, run by its owner. We sand and refinish solid and engineered wood floors in local homes, bringing back floors that have gone dull, scratched, gray or carry old dark spots from spills. A lot of Naperville’s housing dates from the 1980s and 1990s, and many of those original oak floors have never been sanded down to bare wood, just recoated or covered over the years.

Wood Floor Refinishing Service Across Naperville

Our hardwood floor sanding service covers every part of Naperville, from newer subdivisions to the older core of town. That includes homes near the Naperville local historic district and the Naperville federal historic district, along with the newer subdivisions built up over the following decades.

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

Floor Sanding and Refinishing Across Naperville’s Home Ages

Naperville’s housing stock stretches from century-old homes to new builds, and the age of a house changes what we find under the floor. We check the finish, the wood and the construction before quoting.

Pre-1940 original floors. Homes built in 1939 or earlier make up 2.7% of Naperville’s housing. These older floors often still carry an old wax or shellac finish from before polyurethane was standard, and that old finish has to come off completely before new coats will bond, which adds a removal step to the job.
Mid-century homes, 1940-1979. This era accounts for 24.1% of Naperville’s housing stock. In homes from before 1978, our prep follows EPA RRP lead-safe practices, with containment and HEPA cleanup during sanding.
Multifamily units and condos. These buildings make up 36.7% of Naperville’s housing, often with engineered wood glued over concrete. Engineered floors can only be sanded if the wear layer, the real wood on top, is thick enough, so we measure it before quoting.
Homes built since 2000. About 21.1% of Naperville’s housing was built in 2000 or later, and many of these have factory-finished, aluminum-oxide-coated boards. That hard factory finish needs different sanding steps than an on-site finish, and it changes the price per sq ft.

Our Professional Hardwood Floor Refinishing Process and Timeline in Naperville

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 Naperville Homeowners Choose Big Bro Hardwood as Their Floor Refinishers

Naperville homeowners get a crew that respects the town’s daytime work hours and keeps dust and mess contained, whether your home sits near the historic core or out in a newer subdivision.

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.

Dust-Controlled for a Cleaner Home

Dust-controlled sanding keeps Naperville homes clean while we work, including older houses built before 1950 that still have original plaster walls and trim, though edges can collect some fine residue.

Daytime Hours Only

Naperville’s work-hour rule lets sanding happen only between 7 a.m. and 7 p.m., any day of the week, so we schedule the loud part of the job within that window every time.

No Permit Delays

Cosmetic interior work such as refinishing does not need a town permit in Naperville, so we can start your project as soon as the estimate and schedule line up.

Color Samples on Your Floor

Color samples go down right on your own floor, not from a printed chart, which matters in homes near Naperville’s historic district where original trim and oak tones vary from house to house.

HOA and Condo Scheduling

Condo and townhome buildings often ask for written notice and quiet hours before work starts, which we provide along with proof of insurance.

Pet- & Family-Safe Finish Options

Finishes get chosen with families and pets in mind for Naperville’s many single-family homes, and we walk you through odor, dry time and room limits before the first coat goes down.

We had existing hardwood refinished along with installation of new hardwood in a carpeted area of our house. We were very pleased with the work that was done. Donatas and his team were very easy to work with. I would highly recommend them.

Frequently Asked Questions

Why Do So Many Naperville Homes Built in the 1980s Need Full Sanding?

Naperville’s median home dates to 1989, and a lot of that original oak has only been recoated or covered over the years, never sanded down to bare wood. Once an old finish wears through or grays, a full sand becomes the real fix.

Can You Schedule Hardwood Floor Sanding on Saturdays in Naperville?

Saturday sanding works fine. Naperville doesn’t restrict construction noise to weekdays only, so we can plan the loud part of your job around a weekend if that suits your household better.

Are Original Floors in Older Naperville Homes Narrower Than Modern Oak?

Often, yes. The oldest homes in town tend to have narrower, hand-cut planks instead of today’s wider milled boards, which can make an exact color and width match harder when a board needs replacing.
