Big Bro Hardwood is a hardwood floor refinishing company working in Downers Grove, 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 water marks. The median home here was built around 1974, and plenty of 1960s and 1970s ranches and split-levels still have their original oak under carpet or an old finish, which we check before quoting.
Our hardwood floor sanding service covers every part of the village. We work in Downtown Downers Grove, Randall Park, Prince Pond, Denburn Woods, Orchard Brook, Belmont and Downers Grove Gardens, along with the Maple Avenue and Main Street historic districts.
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: 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 |
Several things in Downers Grove homes can add steps, cost or days to a refinishing job, from old finishes to thin original oak. We check for each one before quoting your floor.
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.
Downers Grove runs from early Sears-kit houses to 1960s ranches to newer condo buildings, so your floor’s age and setup shape the plan before we sand a single board.
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.
Village code allows construction work from 7 a.m. to 7 p.m., Monday through Saturday, with no heavy construction on Sunday. We schedule sanding and finish days inside that window so your project stays on the right side of the rule.
Downers Grove requires job site debris in a covered dumpster or container set back five feet from the front and side lot lines, never on parkways or sidewalks. We plan where materials sit before work starts so cleanup never becomes a problem.
Many Downers Grove homes are 1960s and 1970s ranches and split-levels, often home to families with kids and pets underfoot. We pick low-VOC finishes and tell you exact dry times before move-back, not after.
Multi-unit buildings make up close to 30% of the village’s housing, many of them townhouses and condos with shared hallways. We check each building’s access and schedule around it before quoting the job.
Homes here range from Queen Anne and Craftsman houses to Prairie and Mid-Century designs, each built with different species and board widths. We check the wood and its condition on site before we quote a sand or a color change.
Prince Pond is mostly single-family detached homes from the mid-20th century, often with busy family rooms and high foot traffic. We match the sheen and finish to how hard the room gets used day to day.

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.Read more
We would highly recommend Big Bro Hardwood!
Yes, we work in Belmont’s condo and apartment buildings as well as its houses. Shared hallways mean we check building access before scheduling, since moving sanding equipment through a lobby takes more planning than a driveway job.
No, Belmont Park has no homeowners association bylaws or mandates, so there’s no board approval step before we start. We still confirm parking and work hours with you directly, the same as any house in the village.
Access changes the price. A ground-floor house is priced differently than a building with hallways, elevators or limited parking, which is common where Downers Grove has townhouses and condo construction. We quote per project after seeing the access ourselves.
Tell us about your floors and we'll get back to you within 24 hours.
