Big Bro Hardwood is a hardwood floor refinishing company working in Darien, IL, run by its owner. We sand and refinish solid and engineered wood floors in Darien homes, bringing back floors that are dull, scratched, gray or marked by old water damage. Nearly half the housing in Darien went up between 1960 and 1979, so a lot of these houses still have their original oak floors under layers of old carpet or a tired finish, and that wood is usually worth saving.

Hardwood Floor Refinishing Service Across Darien Subdivisions

Our hardwood floor sanding services cover every part of Darien. That includes the post-war subdivisions of Marion Hills, Brookhaven, Clairfield and Hinsbrook, along with the older Cass and Lace areas that trace back to Darien’s stagecoach-era settlement near Cass Avenue.

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 Darien’s Home Ages Shape a Hardwood Refinishing Job

Darien homes span decades of construction, and the build era often decides what’s hiding under the floor. We check for these before quoting any wood floor refinishing job.

Homes Built Before 1978. Darien’s median home was built in 1978, so a good share of the city’s houses fall right at or before that line. In those homes, our prep follows EPA RRP lead-safe practices, with containment and HEPA cleanup, before any sanding starts.
1940s and 1950s Houses. About 7.7% of Darien’s housing went up between 1940 and 1959, old enough that the original floor finish is often wax or shellac rather than modern polyurethane. That old finish has to be identified and stripped before new coats will bond, which adds a step most newer floors skip.
1980s and 90s Subdivisions. Nearly 38% of Darien homes were built between 1980 and 1999, and the oak in many of them has already been sanded once or twice over the years. We check how much wear layer is left before we commit to a full sand, since a floor can only take so many passes.
Townhomes and Multi-Unit Buildings. About 15.4% of Darien’s housing sits in buildings of 5 to 49 units, with another 2.4% in larger structures, and many of those floors are engineered rather than solid wood. Engineered boards only take a sanding if there’s enough solid wood on top of the plywood base, and we check that layer before quoting a price.

Our Professional Hardwood Floor Refinishing Process and Timeline in Darien

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 Darien Homeowners Choose Big Bro Hardwood as Their Floor Refinishers

Darien’s mature subdivisions sit next to newer builds, and no two jobs look the same, so we size up your floor on site before giving you a firm price.

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.

City-Set Work Hours

Darien allows construction work from 6:30 AM to 10:00 PM on weekdays and 7:30 AM to 10:00 PM on weekends, so we schedule sanding days inside those hours and never push past them.

Overnight Parking Rules

Overnight street parking is restricted in Darien between 2:00 AM and 6:00 AM, so our truck and trailer sit in your driveway or we get permission ahead of the job to avoid any issue.

Protection for Adjacent Areas

Covering doorways, cabinets, trim and vents matters most in Darien’s older ranch and split-level layouts, where narrow hallways mean equipment has to pass through finished rooms to reach the floor.

Wood Type & Condition First

Checking the species and finish comes first, even in Darien homes built after 2000, since newer construction can still mean engineered flooring or a factory finish that changes how we quote the job.

Debris Pickup Rules

Leftover flooring and old finish pulled from your home can sit at the curb no more than 24 hours before pickup under Darien’s rules, so we plan hauling around that window.

Pet- & Family-Safe Finish Options

Many of Darien’s oldest homes near Cass and Lace date to before 1939, and families there often ask about fumes, so we use low-VOC water-based finishes that leave no strong smell once cured.

We hired Donatas to refinish hardwood floors in our 56-year-old Darien house last week and we are very pleased with the results. We dreaded the project because we had to shuffle furniture into other rooms and because of my preconceived notion that the entire house would be covered in sawdust. Well, I have to say it was nowhere near as bad as anticipated! Donatas sealed off adjacent areas and kept the dust down to a minimum, vacuuming up at the end of each day. We were very impressed with his attention to detail and overall work ethic, going out of his way to fix an unexpected issue resulting in a very long day for him. Ours was a week-long project, followed by a five-day curing period and Donatas made it as painless as possible for us. We feel very comfortable giving Big Bro Hardwood and Donatas in particular a five-star review and highly recommend them!

Frequently Asked Questions

What Happens If Flooding Has Affected a Darien Basement Floor?

Flooding and rising water tables have caused basement and foundation problems in parts of Darien. Before sanding any floor near an affected area, we check subfloor moisture, since damp wood under the finish will cause new coats to fail even if the surface looks dry.

Does My Darien Subdivision's HOA Need to Approve the Refinishing Work?

Some Darien subdivisions have an active homeowners association that reviews contractor work. If yours does, we can provide a certificate of insurance and a written outline of the job before we schedule.

Where Do You Keep Tools and Materials During a Job in Darien?

Darien’s rules do not allow construction tools or materials to sit in a front or street-facing side yard. We keep our gear in the garage or on the trailer in your driveway for the length of the job.
