Why moisture testing matters in Florida
Before covering a concrete slab or wood subfloor, check the moisture conditions underneath. Orlando's humidity, rain, and air-conditioning cycles can affect a building even when its floor looks dry. Concrete can release moisture long after its surface feels ready. A previous leak, poor drainage, or moisture entering below a slab can also create problems that a quick visual inspection misses.
Installing over an unsuitable surface can lead to cupping, damaged joints, adhesive failure, or mold where conditions allow it. Waterproof flooring does not make the slab or the space beneath it waterproof. Testing helps identify a concern before materials and installation labor are committed.
Most manufacturer warranties require testing before installation
Many flooring and adhesive manufacturers require documented moisture testing before installation. The exact requirement depends on the selected product, installation method, substrate, and adhesive. We check the applicable instructions rather than treating one reading or limit as suitable for every floor.
Keep the results with your product and installation records. Testing is not a promise of warranty approval: the manufacturer's complete requirements still apply, including preparation, site conditions, and ongoing moisture control. Ask us to review your selected flooring before work begins.
How we test
We test concrete slabs and wood subfloors with calibrated moisture meters and, when a manufacturer requires it, in-slab relative-humidity (RH) probes. We will confirm the method required by your flooring, adhesive, and substrate before scheduling the assessment. These methods are not interchangeable.
We review the floor area, signs of previous water damage, and the installation instructions with you. The estimate should identify the agreed testing scope. Any required conditioning period, test locations, and acceptance limits must follow the chosen method and product instructions, not an assumed universal number.
What happens if readings are high?
We discuss the cause and suitable next steps before installation proceeds. An active leak or drainage problem may need attention first. Depending on the product and substrate, the installation system may require an approved moisture barrier, underlayment, or sealing treatment. A barrier cannot replace repairs to an active water source.
See our subfloor preparation and repair service, SPC/WPC moisture barrier, and flooring accessory options. Product compatibility must be checked before purchase; not every underlayment is a moisture barrier, and attached padding alone does not establish moisture protection.
Which floors need moisture checks?
Discuss testing before LVP installation, laminate installation, or hardwood installation. Floating floors and glue-down systems have different requirements, but neither should be installed over unresolved moisture conditions. Existing flooring can conceal a problem, so allow for assessment when planning removal and replacement.
Moisture testing FAQs
Does waterproof vinyl still need a moisture check?
Yes. Check the installation instructions: waterproof planks do not prevent moisture beneath the floor or remove the manufacturer's substrate requirements.
Can you install immediately after testing?
Scheduling depends on the method, results, and any preparation needed. We confirm the next steps after reviewing the product requirements.
Does an old slab need testing?
Age alone does not prove a slab is suitable. Leaks, drainage, and building conditions can change over time.
How do I arrange an assessment?
