CDS Hardwood Floors
Hardwood Floor Moisture Testing in MD, VA & DC
Quick Answer
Moisture testing measures water content in subfloor, slab and hardwood material before installation — the single most important step for preventing cupping, gapping and delamination.
The DMV has severe seasonal humidity swings — 65%+ in summer, 15% in winter with heat on. Hardwood installed at the wrong moisture content will fail no matter how skilled the installer.
We test every job with calibrated pin and pinless meters, calcium chloride tests on slabs, and RH probes when required. Numbers get documented in your project file.
Key Takeaways
