Hardwood floor thickness is one of those decisions most buyers don’t know they need to make until they’re already standing in a showroom. The wrong choice doesn’t just affect how the floor looks; it affects how long it lasts, whether it can be refinished, and whether it will hold up in Colorado’s dry climate. Centennial, CO hardwood flooring has specific demands that not every product on the market is built to handle, and thickness plays a bigger role in that than most people expect.
At Floor & More, we’ve been helping Centennial homeowners work through exactly this decision for years. Here’s what actually matters.
What Hardwood Floor Thicknesses Are Available?
Hardwood flooring comes in three standard thickness categories:
- 3/8 inch: engineered hardwood, thinner profile, used in floating or glue-down installs
- 1/2 inch: engineered hardwood, mid-range stability, works well over radiant heat and concrete subfloors
- 3/4 inch: solid hardwood, the traditional standard, nail-down installation over wood subfloors
Each thickness serves a different application. The right one depends on your subfloor type, your installation method, and how long you plan to stay in the home.
Does Hardwood Floor Thickness Affect How Long It Lasts?
Yes, but not in the way most buyers assume.
Thickness doesn’t determine the surface durability of the floor. What determines that is the wear layer, which is the amount of usable wood above the tongue-and-groove joint that can be sanded and refinished over time.
- Solid 3/4 inch hardwood has roughly 1/4 inch of wear layer above the tongue. It can be refinished 4 to 5 times across its lifespan.
- Engineered 1/2 inch hardwood typically has a 3mm to 6mm wear layer. Depending on the product, it can be refinished once or twice.
- Engineered 3/8 inch hardwood has a thinner wear layer and is generally refinished once, if at all.
If you’re putting hardwood in a high-traffic area and want it to last 40 or more years, 3/4 inch solid is the right call, provided your subfloor supports it. If you’re in a basement or over a concrete slab, engineered is the correct choice regardless of thickness preference.
Which Hardwood Thickness Works Best for Colorado Homes?
Colorado’s climate creates a specific challenge for hardwood floors. The state’s low humidity, particularly in winter, causes wood to contract and expand more than in other regions. Solid hardwood is more sensitive to this movement than engineered hardwood.
Our recommendation for most Centennial homes:
- Main level over wood subfloor: 3/4 inch solid hardwood or 1/2 inch engineered. Both perform well with proper acclimation.
- Over concrete slab or basement subfloor: 1/2 inch engineered hardwood. The layered plywood core resists moisture-related movement.
- Over radiant heat systems: 1/2 inch engineered hardwood. Solid hardwood is not recommended over radiant heat.
Acclimation matters regardless of thickness. Hardwood should sit in the installation space for a minimum of 3 days before installation so the wood adjusts to the room’s humidity level.
What Is the Difference Between Solid and Engineered Hardwood Thickness?
Solid hardwood is milled from a single piece of wood, top to bottom. At 3/4 inch, it’s thick enough to nail directly to a wood subfloor and sand multiple times over its lifespan.
Engineered hardwood is a real wood top layer, called the veneer or wear layer, bonded to cross-stacked plywood layers underneath. The total thickness ranges from 3/8 inch to 3/4 inch, depending on the product. Because the plywood core is dimensionally stable, engineered hardwood handles humidity variation better than solid wood.
The surface of both looks identical once installed. The difference shows up in installation flexibility and long-term refinishing potential.
Does Subfloor Type Determine Which Thickness You Can Use?
Directly, yes.
- Wood subfloor (most main-level applications): Supports solid 3/4 inch, engineered 1/2 inch, and engineered 3/8 inch
- Concrete slab: Engineered hardwood only. Solid hardwood should not be glued or floated directly over concrete.
- Basement below grade: Engineered hardwood only, with attention to moisture levels before installation
Our team inspects the subfloor at every estimate. If there’s a moisture issue or leveling problem, we address it before any flooring goes down. Skipping that step is the most common reason hardwood floors fail early, and it’s a step a lot of installers skip.
Can Thicker Hardwood Be Installed Over Existing Flooring?
Sometimes. The main factors are door clearance and transition heights.
A 3/4 inch solid floor installed over existing flooring raises the finished floor height by more than an inch when you account for underlayment and the existing material. That can create problems at doorways, transitions to adjacent rooms, and appliance clearances in kitchens.
A 3/8 inch or 1/2 inch engineered product installed over a flat, stable existing floor often works without those clearance issues. Our team checks this during the estimate and lets you know before the project starts whether the overlay is viable.
How Does Hardwood Thickness Affect Installation Cost?
Thicker hardwood generally costs more per square foot for both material and labor. The reasons:
- 3/4 inch solid requires nail-down installation with a flooring nailer, which is more labor-intensive than floating
- Thicker material costs more at the product level
- Subfloor prep requirements are stricter for thicker installations
That said, the price difference between a well-installed 3/4 inch solid floor and a well-installed 1/2 inch engineered floor is often smaller than buyers expect, especially when you factor in refinishing potential and lifespan.

Frequently Asked Questions
What is the most common hardwood floor thickness for residential homes? 3/4 inch solid hardwood is the traditional standard for main-level installations over wood subfloors. Engineered hardwood in 1/2 inch thickness is the most common choice for basements, concrete slabs, and homes in climates with humidity variation.
Can I install solid hardwood in a basement? No. Solid hardwood is not recommended for below-grade spaces. Moisture levels in basements, even finished ones, create too much risk of cupping, gapping, and warping. Engineered hardwood is the correct choice for basement installations.
How long does hardwood floor installation take? A typical room takes one to two days. Larger projects or jobs requiring significant subfloor prep may take longer. Our team provides a specific timeline estimate before the project starts.
Does Floor & More install engineered and solid hardwood? Yes. We install both solid and engineered hardwood across all thickness ranges. Our team handles subfloor inspection, preparation, installation, transitions, and finishing details.
Can hardwood floors be refinished after installation? Solid hardwood can be sanded and refinished multiple times over its lifespan. Engineered hardwood can typically be refinished once or twice, depending on the thickness of the top wear layer. LVP cannot be refinished and must be replaced when worn.
Do you serve areas outside Centennial? Yes. We serve Aurora, Denver, Parker, Highlands Ranch, Littleton, Englewood, Castle Rock, Lone Tree, and 15 or more other Denver south metro communities.
