The foundation of a floor that lasts
What our subfloor preparation service delivers
A gorgeous new floor can still fail if what is under it is wrong. Prep is what keeps a floor flat, quiet and solid instead of squeaky and gapped.
We evaluate and prepare every surface first, correcting unevenness, moisture and old adhesive. It matters most over the concrete slabs common here.
Workmanship guaranteed

We stand behind every job and keep your product warranty valid, then stay a local phone call away.
The details
Why homeowners trust us with subfloor preparation
Here is what sets our subfloor preparation apart, and why Valley homeowners keep choosing State 48 Floors to handle it.
Flat floors, no surprises
Small dips and high spots make planks flex, click and gap. We level and smooth the subfloor so your floor feels solid everywhere.
Moisture done right
Concrete slabs can release moisture that ruins flooring from below. We test levels and add the proper barriers where they are needed.
Why it matters most in Arizona
Slab construction, temperature swings and dry air make prep critical. Cutting this corner is exactly how rushed, low-bid installs fail.

What prep your floor needs
Every home and project is different. A few things move the number, and we walk you through all of them before any work begins.
Slab moisture
High readings call for a moisture barrier to protect the floor from below.
Flatness
Uneven slabs need leveling compound or grinding before install.
Old adhesive
Residue from previous flooring has to be scraped and cleaned away.
Transitions
Height changes between rooms are smoothed so the new floor flows.
