Indianapolis' most requested flooring upgrade

Luxury vinyl plank (LVP) has become the single most requested flooring installation we do across Indianapolis and Central Indiana — and for good reason. It gives you the visual warmth of hardwood or the texture of natural stone, without the maintenance headaches or moisture vulnerability of either. For homeowners balancing style, durability, and budget, LVP consistently comes out as the strongest all-around choice.

We install LVP using manufacturer-spec methods, starting with a proper subfloor assessment — not just laying planks over whatever's already there. That distinction matters more than most homeowners realize: a beautiful LVP floor installed over an uneven or moisture-compromised subfloor will show problems within a year or two, no matter how good the material itself is. We handle the prep work most installers skip, because it's the difference between a floor that looks great at the walkthrough and one that still looks great five years later.

What we do

Subfloor prep is what separates a floor that lasts decades from one that starts showing problems in two years.

Self-Leveling Compound

For concrete or wood subfloors with low spots, dips, or uneven sections, we apply self-leveling compound to create a flat surface that your new floor can sit on without rocking, cracking, or developing hollow spots over time.

Luan Installation

Luan is a thin plywood underlayment applied over existing subfloors to create a smooth, even surface — particularly useful for vinyl and laminate installations over older wood subfloors with imperfections that self-leveler alone won't address.

Plywood Subfloor Repair & Installation

Wood subfloors that are soft, squeaky, or structurally compromised need to be addressed before any new floor goes in. We secure, replace, or supplement plywood subfloor panels as needed to give your new floor a solid foundation.

Sanding Down High Spots

High spots are just as problematic as low ones — they cause floating floors to rock, tile to crack, and hardwood to telegraph unevenness. We grind or sand down high spots on both concrete and plywood subfloors to meet the flatness tolerance required by your floor type.

Moisture Barrier Installation

We install thin-film plastic moisture barriers over concrete subfloors for LVP and laminate installations where ground moisture migration is a concern. We also use moisture-resistant underlayment systems for specific applications.

Concrete Subfloor Prep

Concrete subfloors require their own preparation process — grinding high spots, filling cracks and low areas, testing for moisture, and applying primer before self-leveling compound where needed. We handle all of it.

Common subfloor problems we fix

Uneven or sloped subfloors

Settling, old construction, or previous poor installs can leave a subfloor out of level — we correct this before new flooring goes down.

Moisture issues

Especially common in basements — we test moisture levels and address the source before it becomes a problem under new flooring.

Squeaky floors

Loose subfloor fasteners are the usual culprit — often fixable without replacing the subfloor entirely.

Old adhesive or residue

Leftover adhesive from a previous flooring install needs full removal — new material won't bond correctly over it.

Damaged or rotted sections

Water damage or rot requires cutting out and replacing the affected subfloor section before anything new goes on top.

Where subfloor prep matters most

Basements top the list, given how common moisture issues are below grade. Older Indianapolis homes are next — decades of settling and multiple past flooring installs often leave a subfloor that needs real attention before anything new goes down. Kitchens and bathrooms carry their own risk from water exposure over time.

Subfloor prep is included as part of every installation we do — LVP, tile, laminate, hardwood, and carpet all start here — but it's also available on its own if your subfloor needs work independent of a flooring replacement.

Common questions about subfloor prep

How much does subfloor prep cost?

Costs vary widely based on what's needed — minor leveling runs less than major moisture remediation or section replacement. It's included as a transparent line item in your free estimate rather than a flat rate.

How do I know if I need subfloor prep?

Squeaks, visible unevenness, soft spots, or a musty smell in a basement are common signs. If you're unsure, we assess subfloor condition as part of every free in-home estimate.

Does subfloor prep delay my flooring project?

It can add time depending on the extent of the work, but skipping needed prep to save time almost always costs more later when the new flooring fails prematurely.

Is subfloor prep included in my flooring estimate, or billed separately?

It's assessed and quoted as part of your free estimate for any flooring project, so there are no surprise line items once work begins.

Can you fix squeaky floors without replacing my flooring?

Often yes — many squeaks come from loose fasteners that can be addressed without removing the existing flooring, depending on access.

How does moisture testing work?

We use a moisture meter to check subfloor moisture content before recommending flooring types or prep work, particularly important in basements.
