We noticed our laminate floor near the kitchen had started to cup and figured it was just age. The subfloor underneath was actually damaged from a slow leak. They pulled up the affected section, dried it properly, and matched the new flooring well.

Good to know
Floor & Subfloor Mold Removal in Waltham, MA: common questions
How do I know if my floor has mold underneath?
Warping, cupping, soft or spongy spots, and a persistent musty smell near the floor are the main signs. Discoloration where flooring meets a wall or appliance is another clue worth checking.
Will you install new flooring after removal?
We handle removal, subfloor assessment, and drying, and can coordinate flooring replacement to match your existing material as closely as possible.
What flooring types are most at risk?
Laminate and vinyl plank tend to hide subfloor damage the longest since the surface looks fine until the base underneath has already softened. Tile and hardwood usually show warning signs a bit earlier.
Is the floor & subfloor mold removal you do in Waltham to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across Middlesex County.
Can the subfloor always be saved?
Not always. Plywood that's only been briefly damp can often be dried and reused. Particleboard subfloor that's absorbed water usually swells and loses strength, and typically needs replacement.
Is this an emergency if the leak has stopped?
It's less urgent than an active leak, but the affected area should still be checked reasonably soon, since trapped moisture under flooring can continue causing damage even after the original leak is fixed.
Do I need to leave my Waltham home during the work?
Usually no. We seal the work area under negative air, so most of the Waltham home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Do you serve Waltham?
Yes. We cover all of Waltham, including Bemis, West Newton, Nonantum, and the rest of the Waltham area. We are based in Auburndale, about 5 minutes from our Auburndale base, and answer our own phone around the clock.
