Hardwood Floor Installation
Professional hardwood floor installation by Carpet Services Incorporated (CSI). Solid and engineered wood, nail-down and floating methods, installed by in-house crews across Chicagoland since 1979.
Hardwood Floor Installation Built for Chicagoland Homes
A hardwood floor installation is one of the most valuable investments you can make in your home or commercial property. Hardwood adds warmth, character, and lasting appeal that no other flooring type can replicate — and it increases property value more consistently than carpet, vinyl, or laminate. Carpet Services Incorporated (CSI) has been installing hardwood floors across the Chicagoland area since 1979, with in-house crews who understand the unique demands of Midwest climate and construction.
Chicagoland homeowners face specific challenges that affect hardwood performance: dramatic seasonal humidity swings that cause planks to expand and contract, road salt that corrodes finishes each winter, and subfloor conditions in older homes throughout Berwyn, Oak Park, and Cicero that require specialized preparation before the first plank is laid. CSI addresses every one of these factors during the planning and installation process, which is why our hardwood floors perform beautifully year after year.
Unlike contractors who subcontract portions of the job, CSI handles the entire project with one crew — from the initial estimate through subfloor preparation, acclimation, installation, and the final walkthrough. One company, one warranty, one point of contact. That is the way we have done it for over 45 years, and it is the reason clients across DuPage, Cook, Kane, and Will counties keep calling us back.
Wood Floor Installation Options for Every Space
Not every hardwood installation is the same. The right method depends on the wood product, the substrate beneath it, and the conditions inside the building. CSI installs every type of hardwood using the method that delivers the longest-lasting result for your specific project.
Nail-Down Solid Wood
The traditional method for installing solid hardwood, nail-down installation secures each plank to a wood subfloor using cleats or staples driven through the tongue at a precise angle. This technique produces the most permanent, secure bond and allows the wood to expand and contract naturally with seasonal humidity changes. Nail-down is the gold standard for solid oak, maple, hickory, and walnut installations above grade over a plywood substrate.
Glue-Down Engineered Plank
Glue-down installation bonds engineered hardwood directly to the substrate — concrete, plywood, or existing flooring — using a moisture-rated adhesive. This method is ideal for concrete slabs in basements and ground-level rooms where nail-down is not possible, and it provides excellent sound dampening and stability. CSI uses only manufacturer-approved adhesives that carry moisture-vapor barriers built into the bond.
Floating Click-Lock
Floating installation locks the planks together at the edges without fastening them to the substrate, resting instead on a cushioned underlayment pad. This is the fastest hardwood installation method and works well for engineered click-lock products over concrete, existing flooring, or any flat substrate. It also allows for easier plank replacement down the road if damage occurs in a single area.
Species and Grade Selection
The species and grade of wood you choose directly affects both the appearance and the performance of your floor. Oak remains the most popular choice in Chicagoland for its durability and grain character, but maple offers a tighter, cleaner look for contemporary spaces, hickory provides the hardest surface for high-traffic areas, and walnut delivers rich, dark tones for formal settings. CSI carries all major species in multiple grades and plank widths to match your design goals and budget.
Commercial Hardwood
Hardwood floors are no longer limited to residential settings. Restaurants, boutique retail spaces, hotel lobbies, and executive offices across Chicagoland use hardwood to create warm, high-end atmospheres that impress customers and guests. CSI provides professional hardwood installation for commercial projects with after-hours scheduling, phased installation plans, and product recommendations engineered for heavy foot traffic and commercial cleaning regimens.
Prefinished vs. Unfinished
Prefinished hardwood arrives from the factory with its stain and topcoat already applied, which means faster installation and no sanding dust in your home. Unfinished hardwood is installed raw and then sanded, stained, and sealed on site, which allows for a custom color match and a perfectly flush surface between boards. CSI installs both and helps you weigh the trade-offs based on your timeline, design goals, and tolerance for on-site finishing work.
From Estimate to Finished Hardwood Floor in Six Steps
A successful hardwood installation demands precise sequencing and proper acclimation. Rushing any step — especially moisture testing and wood conditioning — leads to gapping, cupping, or buckling down the road. CSI has refined this process across thousands of installations to deliver floors that stay flat and beautiful for decades.
Free On-Site Estimate
A CSI estimator visits your property to measure every room, inspect the subfloor, check for moisture, and discuss your wood species, plank width, and finish preferences. You receive a written, itemized estimate on the spot — every material, every labor cost, and any subfloor preparation required is documented so there are no surprises after work begins.
Material Delivery and Acclimation
CSE delivers your hardwood to the installation space and monitors the moisture content of both the wood and the subfloor using pin meters. Solid hardwood acclimates for a minimum of three to five days; engineered wood for at least 48 hours. This step is non-negotiable — installing wood that has not acclimated to your home's humidity level is the number one cause of cupping and gapping complaints.
Subfloor Preparation
Before the first plank is placed, the CSI crew prepares the substrate to manufacturer specifications. This includes verifying flatness within the required tolerance (typically 3/16 inch over 10 feet), addressing any squeaks or loose boards, applying moisture barriers on concrete slabs, and installing underlayment or felt paper as required by the installation method. A properly prepared subfloor is the foundation of a hardwood floor that performs for decades.
Hardwood Installation
Certified CSI installers lay your hardwood according to the method specified for your product and substrate — nail-down, glue-down, or floating. The crew works row by row, maintaining proper expansion gaps at walls and transitions, and installs any required transition strips between rooms and flooring types. If you chose unfinished wood, this phase also includes on-site sanding and finishing once all planks are laid.
Trim and Detail Work
After the flooring is installed, the crew adds baseboards, shoe molding, and transition pieces that give the project a finished, professional look. Every joint is tight, every corner is coped or mitered, and every transition between rooms is smooth. This attention to detail is what separates a CSI installation from a rushed job — and it is what you will notice every time you walk into the room.
Walkthrough and Warranty
The project manager conducts a final walkthrough with you to inspect every plank, every transition, and every detail. You receive a written warranty covering both materials and labor. If anything needs attention after the crew leaves, CSI returns promptly to make it right at no additional charge. Our hardwood installations are built to last — and we stand behind every one of them.
The CSI Difference in Hardwood Installation
-
One Crew, Every Phase CSI never subcontracted. The same crew that preps your subfloor delivers the wood, monitors acclimation, and installs every plank. No handoffs, no miscommunication, no finger-pointing between contractors when a board does not sit flush.
-
Moisture Tested, Always We test every subfloor with a pin meter and every concrete slab with a calcium chloride test before installing a single plank. Moisture is the number one enemy of hardwood, and Chicagoland basements and ground-level slabs are notorious for hidden vapor. We verify the numbers before we lay the wood — not after it cups.
-
Proper Acclimation Guaranteed Cut-rate installers skip acclimation to finish faster. CSI monitors wood moisture content against subfloor readings and will not begin installation until the numbers align. This discipline is what separates a floor that stays flat for thirty years from one that gaps and buckles in the first winter.
-
Written Warranty Included Every hardwood installation comes with a written warranty covering materials and labor. If anything goes wrong due to our workmanship, we fix it at no charge. That is the confidence 45 years of experience gives our clients — and the peace of mind you deserve.
-
Solid and Engineered Expertise Whether you are installing solid oak on a second-floor plywood subfloor or engineered hickory over a basement concrete slab, CSI has the product knowledge and installation experience to specify the right method. We install both product types every day and will never push a method that does not match your conditions.
What Our Clients Say About Hardwood Installation
"We had white oak installed throughout our first floor — kitchen, living room, and dining room. CSI matched the grain perfectly, acclimated the wood properly, and the nail-down installation is absolutely flawless. No squeaks, no gaps, and the finish is gorgeous. These guys know hardwood."
"Our 1960s ranch had carpet over the original subfloor, and we were nervous about what they would find underneath. CSI pulled the carpet, reinforced two soft spots in the plywood, and had hickory nailed down in three days. The subfloor prep made all the difference — the floor is rock solid."
"We needed engineered hardwood over a concrete slab in our finished basement and got three quotes. CSI was the only contractor who tested the slab for moisture before giving us a price. That told us everything we needed to know about how seriously they take the installation. The floor has been perfect through two full heating seasons."

Hardwood Floor Installation FAQ
Hardwood installation cost depends on the wood species, plank width, installation method (nail-down, glue-down, or floating), and the condition of your subfloor. Carpet Services Incorporated (CSI) provides free on-site estimates that itemize materials, labor, and any subfloor preparation so you know the full cost before work begins. Call (708) 222-8200 to schedule your assessment.
A typical 1,000-square-foot hardwood installation takes two to four days depending on the installation method, whether old flooring must be removed first, and the acclimation time required for the wood. Nail-down solid hardwood takes longer than a floating engineered floor. Your CSI estimator will provide a specific timeline during the free assessment.
Yes. Solid hardwood should acclimate in the installation space for a minimum of three to five days, and engineered wood for at least 48 hours, so the moisture content of the wood adjusts to your home's humidity level. CSI delivers the material to your property ahead of the install date and monitors moisture readings with a pin meter to confirm the wood is ready before the crew begins laying planks.
Engineered hardwood can be installed directly over concrete using a glue-down or floating method, provided the slab passes a calcium chloride moisture test. Solid hardwood over concrete requires a plywood subfloor or a floating floor system with a vapor barrier. CSI tests every concrete substrate before installation and recommends the best method for your specific conditions.
Nail-down installation fastens each plank directly to a wood subfloor with cleats or staples and is the traditional method for solid hardwood. Floating installation locks the planks together at the edges without fastening them to the substrate, using a click-lock or tongue-and-groove glue system, and is typically used for engineered wood. Nail-down provides the most secure, permanent bond; floating offers faster installation and can be placed over a wider range of substrates.
Most hardwood installation projects do not require you to vacate. However, you will need to stay off the newly installed flooring for the period specified by the manufacturer, which is typically 12 to 24 hours for glue-down products and a few hours for floating floors. Nail-down installations can accept foot traffic almost immediately. CSI coordinates the schedule to minimize disruption and advises you on any temporary access restrictions.
