(630) 418 4139Big Bro Hardwood is an employee-owned hardwood flooring company serving Naperville and the surrounding suburbs. We install, sand, stain, refinish, and repair solid and engineered wood floors, starting around $3 a square foot. In 17+ years, we have completed 500+ floors across the area – refinishing original red oak strip floors in Naperville’s mid-century ranches and split-levels, adding hardwood to two-story colonials where carpet once covered plywood subfloors, and installing engineered plank with proper moisture control in newer production-built homes near South Naperville.








The same small crew stays with your project from the first measurement to the last coat – no rotating subcontractors, no surprises. We give you a clear, line-by-line estimate and a free in-home visit within 24 hours. Our vacuum-assisted equipment captures 95%+ of sanding dust, and we finish with Bona and Loba products that are kid- and pet-safe once fully cured.
Premium Results From $3/sq ft
Quality hardwood floors in Naperville do not have to come with an intimidating price. Our refinishing services start at just $3, and installation pricing is straightforward with itemized, line-by-line estimates so you always know what you are paying for. Use our hardwood floor cost calculator to get a quick sense of your project before we even step through the door.
Serving Naperville and Nearby Suburbs
We work with homeowners throughout Naperville and 30-plus suburbs across the area. Every project is handled by the same small, experienced crew from start to finish. There are no rotating subcontractors and no handoffs between strangers. You get consistent communication and consistent workmanship on every job, whether it is a single room or an entire house.
Floor Condition and Moisture Come First
Naperville’s humid continental climate puts real demands on hardwood. Before any installation or refinishing begins, we check subfloor flatness and moisture levels, look for existing damage, and confirm the conditions are right. Skipping those steps leads to cupping, gapping, and loose boards down the road. We would rather catch a problem early than have you call us back to fix something avoidable.
17+ Years of Hands-On Hardwood Experience
Donatas, Valdas, and Slavek bring over 17 years of combined hardwood experience to every project, covering installation, sanding, staining, refinishing, repair, and staircase work. That depth of hands-on practice means we recognize issues quickly, choose the right approach for your specific floors, and handle both older solid oak and modern engineered wood with equal confidence.
GREENGUARD-Certified, Pet-Safe Finishes
We use Bona and Loba products on every finish job. These are low-VOC formulas (Bona GREENGUARD Gold, Loba EMICODE EC1) that are safe for kids and pets once cured. Whether your floors are solid hardwood or engineered, you get a durable, beautiful result without harsh fumes lingering in your home long after the crew has packed up.
Tailored for Naperville Homes
Most Naperville homes were built during the suburban expansion of the 1960s through the early 2000s, and we know that construction well. From plywood subfloors in two-story colonials to concrete slab sections in newer townhomes, we adapt our process to what is actually under your feet. We also acclimate wood on site and follow NWFA guidelines to account for the seasonal humidity swings this area sees every year.
From newer two-story colonials in south Naperville to split-levels near the Riverwalk, we handle every hardwood flooring need with the same small, experienced crew from start to finish.





We’re a hardwood floor company based in the Naperville area, with 17+ years of hands-on experience in hardwood floor installation, floor refinishing, staining, and repair services. Our team is small, focused, and takes pride in doing every job right, from the first measurement to the final product.

Naperville's mix of mid-century ranches, two-story colonials, and newer subdivision builds each come with their own subfloor conditions and climate demands, so we adjust our approach before the first board goes down.
1
Mid-Century Ranches and Split-Levels
Homes built in Naperville’s earlier suburban expansion, roughly the 1960s and 1970s, often have original red oak strip or maple parquet flooring hiding under carpet. We check the boards and subfloor in person before recommending anything. If the wood is sound, sanding and refinishing is almost always the smarter call over replacement.
2
Pre-1978 Homes and Lead-Safe Work
Any Naperville home built before 1978 may have lead-based paint under old finish layers. We follow EPA Lead RRP protocols on every job where that risk exists: proper containment, HEPA vacuums, and verification before we leave.
3
Additions, Remodels, and Blended Floors
Naperville homeowners remodel often, and new sections rarely match the existing floor right away. We select species, cut, and stain to blend old and new as closely as possible, and we sand the whole area together so the transition disappears.
4
Newer Subdivisions and Production Builds
Homes built in Naperville’s south-side and master-planned communities through the 1990s and 2000s typically have plywood or OSB subfloors over wood joists. We check flatness and moisture content before installing wide-plank engineered or prefinished solid hardwood, because a subfloor that is even slightly off will show in the finished floor.
5
Townhomes and Slab-on-Grade Sections
Newer townhomes and some production-built homes near commercial corridors have concrete slabs under the main living area. On slab, we use glue-down or floating engineered wood with the right adhesive and moisture barrier, and we coordinate scheduling around HOA rules when they apply.
6
Humidity and Seasonal Movement
Naperville winters are dry and cold, summers are humid, and that swing puts real stress on hardwood. We acclimate every delivery of wood on site, and we advise keeping indoor humidity between 30-50% year-round to prevent gapping, cupping, and cracking after installation.
In many Naperville homes the original wood is worth saving rather than replacing - the only way to know is to look at the subfloor and boards up close.
1
Call or send the form, tell us about your floors, and we’ll set a time to come look.

We measure, check the wood and subfloor, talk through color and options, and leave you an itemized estimate.

Our crew handles prep, sanding, install, stain, and finish on a dust-controlled setup, cleaning up daily.

We do a final walkthrough, go over care and timing, and stand behind the work.
This one speaks for itself. A homeowner in Naperville reached out about floors in a late-20th-century two-story that had taken years of heavy foot traffic - the boards were worn down, scratched up, and had lost any real finish. We sanded them back to bare wood, repaired the damaged areas, and refinished them from scratch. Same floors, no replacement. Take a look at the before and after photos below and judge the results for yourself.

It actually works in your favor. Most Naperville single-family homes from the 1960s through the early 2000s were built with 3/4-inch plywood or OSB subfloors over wood joists, which is ideal for nail-down solid hardwood. We check subfloor flatness and moisture before any installation, following NWFA guidelines, so you get a stable result whether your home is a two-story colonial, a split-level ranch, or a newer executive-style build in a south Naperville subdivision.
It matters more than most homeowners expect. With January lows near 15°F and warm, humid summers, wood expands and contracts significantly across seasons. We acclimate every board on-site before installation and always leave proper expansion gaps. Once your floors are down, we recommend keeping indoor humidity between 30-50% year-round. A programmable humidifier in winter and air conditioning in summer go a long way toward protecting your investment here in Naperville.
Solid hardwood is not a good fit directly over concrete, but engineered hardwood is an excellent option. It can be glued down or floated over a slab with proper moisture control. We test concrete moisture levels before recommending any product or adhesive. Many Naperville homes also have framed main levels above a full basement, which are perfectly suited for nail-down solid or engineered wood. We will tell you honestly what works best for your specific subfloor situation.
Almost always yes, if enough wood thickness remains. Original red oak strip floors were built to last and can typically be sanded and refinished multiple times. We inspect the boards first to confirm there is enough material to sand safely. If the floors are sound, refinishing costs far less than replacement and restores the character that newer flooring simply cannot replicate. We have brought back many tired oak floors across Naperville and nearby suburbs to look genuinely beautiful again.
Refinishing starts at $3 per square foot, and we offer flat-rate pricing for homes under 1,200 square feet. Every project gets an itemized, line-by-line estimate so you know exactly what you are paying for, with no surprises. For a quick ballpark before we visit, try our cost calculator. We also offer 10% off for new clients. The best step is a free in-home estimate, which we schedule within 24 hours of your call.
Refinishing is the right call in most cases. If the boards are structurally sound and have enough thickness left to sand, refinishing costs significantly less than full replacement and produces a beautiful result. We look at board condition, existing finish depth, and any damage before making a recommendation. We only suggest replacement when the wood is genuinely beyond saving – warped, severely thinned, or rotted. Our goal is to give you an honest answer, not to sell you more work than you need.
A typical refinishing project takes two to three days. Installation timelines vary by square footage and scope. You do not need to vacate entirely, but you will need to stay off the freshly coated floors for 24 hours per coat while finish cures. We use vacuum-assisted dustless sanding that captures 95% or more of dust, which makes living around the work much more manageable. We will walk you through the schedule clearly before we start so there are no disruptions you did not expect.
We use Bona and Loba waterborne finishes as our primary products, both low-VOC and safe for kids and pets once fully cured. We also work with Pallmann and DuraSeal depending on the project. These finishes are durable, look great on Naperville homes, and do not off-gas harshly the way older oil-based products did. We are happy to walk you through sheen levels and finish options during your free in-home estimate so you can choose what fits your household best.
