Basement Flooring Installation in St. Louis, MO
Waterproof, moisture-tested, and built for below-grade life. Kelly’s Flooring has been installing basement flooring across St. Louis — Ballwin, Wildwood, Chesterfield, Fenton, Arnold, and the rest of the metro — for more than 45 years.
Basement Flooring That Actually Works in St. Louis
St. Louis basements face challenges most rooms don’t: concrete subfloors, moisture rising from below, big humidity swings between summer and winter, and the occasional water event from heavy spring rains. The wrong flooring choice in a basement leads to warping, mold, adhesive failure, and a callback in a year or two.
Kelly’s Flooring only installs basement flooring we’d put in our own homes — waterproof or moisture-resistant materials, properly tested subfloors, vapor barriers where needed, and the right transitions at the stairs. Every basement install starts with a moisture assessment, not a sales pitch.
- Moisture testing on every basement subfloor before installation
- Waterproof and moisture-resistant materials only
- Concrete subfloor preparation, leveling, and patching
- Vapor barrier installation when readings call for it
- Finished basement, rec room, home gym, and walkout floors
- Free in-home estimate including the moisture assessment
Best Flooring for Basements in St. Louis
These materials are specifically chosen for their ability to handle moisture, humidity, and concrete subfloors common in St. Louis homes.
Waterproof Luxury Vinyl Plank
The number-one basement flooring choice in St. Louis. 100% waterproof, installs directly over concrete, available in convincing wood and stone looks. Brands we recommend most: COREtec, Shaw Floorté, and Mohawk SolidTech.
Explore Luxury Vinyl →Porcelain & Ceramic Tile
Fully waterproof, extremely durable, and a smart pick for basement bathrooms, laundry rooms, and walkout entries. Wood-look and stone-look porcelain styles let you keep the high-end look without the moisture risk.
Explore Tile →Carpet & Carpet Tile
Modular carpet tiles with waterproof backing are ideal for basement rec rooms, home theaters, and play areas. If a tile gets soaked, replace just that square. Plush wall-to-wall carpet is fine for dry basements with proper moisture mitigation.
Explore Carpet →Water-Resistant Laminate
Modern water-resistant laminate is a budget-friendly option for dry, tested-low-moisture basements. Quick floating installation over concrete with proper underlayment. Not a true waterproof product — we’ll tell you if your basement is a fit.

A predictable, moisture-aware process from estimate to finished floor.
1. Moisture Assessment
We test the concrete slab for moisture using calcium chloride or relative humidity probes. The results determine which flooring is safe to install — and whether a vapor barrier or moisture-mitigating primer is needed first.
2. Subfloor Prep
Cracks are filled, low spots are leveled, and high spots are ground down. A flat, clean slab is the foundation of a basement floor that lasts.
3. Vapor Barrier & Underlayment
When moisture readings call for it, we install a vapor barrier and the right underlayment to keep humidity from reaching your new floor.
4. Installation
Floating LVP, glue-down tile, modular carpet tile, or stretched carpet — installed by our own crews using the manufacturer’s required methods so the warranty stays in force.
5. Transitions & Trim
Stair noses, doorway transitions, and baseboards finish the job. Expansion gaps are maintained around the perimeter as required for each product.
6. Walkthrough & Care Guide
We walk every room with you, answer questions, and leave you with care instructions and the warranty paperwork before we go.
How Much Does Basement Flooring Cost in St. Louis?
Basement flooring cost depends on three things: the material you choose, how much square footage you’re covering, and the condition of your concrete subfloor.
Luxury vinyl plank is usually the most cost-effective waterproof option for a full basement — comparable to carpet on a per-square-foot basis once installation and pad are included. Porcelain tile sits at a higher price point because of subfloor prep and labor. Carpet tile and traditional carpet are typically the most affordable, with the trade-off being water vulnerability.
The biggest variable in any basement flooring quote is subfloor prep. A flat, clean, dry slab installs quickly. A slab that needs leveling, crack repair, or moisture mitigation adds time and material. That’s why we always do the moisture assessment and subfloor inspection as part of the free in-home estimate — so your quote is the actual price, not a guess.
