Big Bro Hardwood is a hardwood floor refinishing company working in Winnetka, IL, run by its owner. We sand and refinish solid and engineered wood floors in Winnetka homes and condos, bringing back floors that have gone dull, scratched, gray or marked with dark water spots. More than half of Winnetka’s homes were built before 1940, and many still hold their original oak floors under decades of old finish or wear, floors that are almost always worth saving rather than replacing.

Hardwood Floor Sanding Across Winnetka Neighborhoods

Our refinishing work covers every part of Winnetka. We take jobs in Hubbard Woods, Village Green, the Linden and Ridge historic corridor, Indian Hill, the East Side and the Central West Side, in houses ranging from century-old Victorians to mid-century ranches.

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

How Winnetka Homes Change a Floor Sanding Job

Winnetka’s housing runs from 1870s landmarks to homes built after 2010, and each age brings its own floor, from original oak to engineered boards. We check the floor type, the finish and the wear layer before quoting any refinishing work.

Pre-1940 Original Oak. Winnetka’s median home was built in 1938, so a lot of the oak under our sander is original, decades-old wood. Floors that age may have been sanded down before, so we measure the wear layer first and tell you honestly if another full sanding isn’t possible.
Pre-1900 Victorian Finishes. Winnetka still has houses built before 1900, and floors that old often carry an old wax or shellac finish under later coats. Removing that layer before sanding is extra work, priced as its own add-on so you see it on the quote.
Hubbard Woods Italianates. Hubbard Woods’ building boom started in 1872, when fourteen Italianate houses went up west of Green Bay Road. Floors from that era can carry years of old finish and uneven board color, so color testing on your own floor matters more than matching a sample chip.
New Construction Engineered Floors. Winnetka added 245 housing units in 2010 or later, and many of those newer homes have engineered wood floors instead of solid oak. We measure the veneer, the thin top layer of real wood, before quoting, since a floor can only be sanded if that layer is thick enough.
Hubbard Woods Ravines. Ravines near Hubbard Woods and the lakefront bring extra moisture to the air there. We hold the room at 60-80°F and 35-55% relative humidity through sanding and curing so the new finish cures evenly despite that moisture.

Our Professional Hardwood Floor Refinishing Process and Timeline in Winnetka

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 Winnetka Homeowners Choose Big Bro Hardwood as Their Floor Refinishers

Whether your Winnetka house is a 1920s bungalow or a Tudor Revival, you get a straightforward look at your floor’s condition and a clear quote before any sanding starts.

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.

Pet- & Family-Safe Finish Options

Many Winnetka homes went up between 1940 and 1969, the classic ranch and Colonial years families still raise kids and dogs in today. We pick finishes with cure times and odor levels that fit a house still in daily use.

Work Hours We Follow

Village rules limit construction work to 7 a.m. to 7 p.m. on weekdays and 9 a.m. to 6 p.m. on Saturdays, with no work on Sundays or holidays. We schedule sanding days around that window.

Parking on the Job

Parking on Winnetka streets is barred from 2 a.m. to 6 a.m., so we park our crew’s vehicles on site whenever we can and stay clear of your neighbors’ driveways.

Debris Kept Off the Street

Debris from a refinishing job stays on your property in a contained bin, so no street permit is needed. We keep the site free of leftover boards, packaging and sanding dust bags.

Dust-Controlled for a Cleaner Home

Several Winnetka landmarks date from the 1850s through 1937, with original millwork and trim worth protecting. Our containment setup keeps dust off those surfaces, though fine residue still settles at edges and corners.

Clear, Itemized Pricing & Scheduling

Houses here range from a log cabin dating to 1837 to homes finished after 2010, so no two jobs cost the same. Every line of the quote is spelled out before we set a start date.

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

Do I Need a Permit to Refinish Hardwood Floors in Winnetka?

Usually not for refinishing alone. Winnetka requires permits for interior remodeling, but the village doesn’t specifically call out floor sanding and refinishing as needing one. We check with the village before your job if there’s any doubt.

Can Your Crew Sand Floors on a Sunday in Winnetka?

Not for a full sanding job. Winnetka bars construction activity on Sundays and holidays, though minor construction work is allowed from 9 a.m. to 5 p.m. those days. We plan the loud, dusty sanding days for the regular weekday and Saturday windows.

How Do You Handle Condo Buildings When Refinishing Floors in Winnetka?

We get your building’s rules before scheduling. Condo buildings are part of Winnetka’s housing mix, and each one can set its own contractor requirements, so we provide a certificate of insurance and written dust-control documentation and plan around any posted quiet hours.
