We sand and refinish hardwood floors in Northbrook, where many homes date to the 1950s through 1970s with original oak underneath. One crew, owner on every job, no subcontractors, dustless sanding, free in-home estimate within 24 hours.
Big Bro Hardwood refinishes hardwood floors in Northbrook, IL, run by its owner on every job. We sand and refinish solid and engineered wood floors that have gone dull, scratched, gray or carry old water marks from the village’s history of flooding. Many Northbrook homes date back to the 1950s through 1970s, so we often find original oak hiding under carpet in these ranch-style homes.
Our wood floor refinishing service covers all of Northbrook, from historic homes near the Central Business District to newer subdivisions throughout the village.
Sanding and finishing most oak floors over 1,000 sq ft starts at $3–$4 per sq ft, so 1,000 sq ft of oak starts at about $3,000 to $4,000. Nationally, the cost to refinish hardwood floors runs $3–$8 per sq ft. Our prices stay affordable and competitive without cutting corners: Dan (Donatas), the owner, works on every job and treats each floor the way he would treat his own.

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: for new floors, 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 | About every 5 years |
| Deep scratches, gray or worn spots, or you want a new color | Full sanding down to bare wood and new finish coats | About every 10 years, sooner with large dogs |
| 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 | New hardwood flooring; we tell you honestly when a floor can’t take another sanding | Not applicable |
Northbrook homes span eras from 1940s ranches to newer condos, and each era can change what a sanding and refinishing job needs. We check the floor’s age, finish and wear before we quote a number.
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. Photos of your floor give us enough for a rough number; the exact price comes from this visit. Work usually starts 2 to 4 weeks after the estimate, and shorter jobs like a buff and recoat (1–2 days) can sometimes fit in sooner. Buying a home? We can do a free estimate before you close, so the floors are done before the furniture moves in. Clearing the rooms is up to you: we can help move a single sofa and recommend a moving company when a whole floor needs emptying.
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: Sanding
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.
Northbrook’s village permit page does not say sanding needs a permit, so we handle the paperwork questions upfront and tell you plainly if anything in your home changes that.
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.
Colonial Revival homes from the 1920s often hide original oak under layers of old finish. We test color choices right on your own boards in daylight and lamp light, so you see the real result before we commit the whole floor.
The village does not require a permit for floor covering work like carpet or tile removal, but its page stays silent on sanding existing wood floors. We check with the village before quoting, so there are no surprises mid-project.
Older ranches and colonials near the Central Business District often have tight hallways between rooms. We cover doorways, cabinets, trim and vents, and plan how our equipment moves through the house before sanding starts.
Many Northbrook homes still have original oak under newer flooring, and uncovering it stirs up decades of settled dust. We run dust-controlled equipment through the job and expect some fine residue at edges, which we plan to clean up.
Northbrook limits construction work to 7 AM to 7 PM on weekdays and 9 AM to 5 PM on Saturdays, with no work on Sundays or village holidays. We schedule sanding inside those hours every time.
The village has a documented history of flooding, including a 2011 storm that dropped over five inches of rain in a day. Where water has reached a floor before, we check the boards carefully before deciding what the floor can still take.

Big Bro Hardwood was an absolute pleasure to work with. BBH refinished our floors, installed new stairs and installed new flooring in our basement. They repaired a few areas as well. The end result is outstanding. I highly recommend. Thank you!Read more
Only about 2.4 percent of Northbrook homes predate 1940, many clustered near the Central Business District. These floors have likely been sanded many times already, so we measure how much wood is left before promising another full sand on original oak.
Yes, Northbrook has more than 2,400 housing units in buildings of 20 units or more, and many of those are condos with factory-finished or engineered floors. We check the finish type and HOA rules for elevators and shared hallways before quoting, since those add steps a single-family home doesn’t need.
It can. Northbrook’s condo stock runs from larger luxury units to smaller properties, and finish type and floor size change the approach more than square footage alone. We confirm the flooring material and any building rules before giving a number, on either size unit.
