A slow dishwasher supply leak fed months of hidden moisture under the sink cabinet and kitchen island. Here’s how Mold Pro found it, removed it, and prepared the kitchen for reconstruction.
The homeowner first noticed a musty smell that lingered near the sink cabinet and kitchen island. It wasn’t strong, but it didn’t go away — even after deep cleaning the kitchen.
Mold Pro’s investigation revealed a slow leak from the dishwasher supply connection, combined with long-term moisture accumulation beneath the cabinetry and island structure. Moisture had become trapped beneath the toe-kicks, cabinet bases, lower drywall sections, and portions of the subfloor — creating ideal conditions for mold amplification. By the time the smell was noticeable upstairs, the damage was already extensive.
This is a common pattern in Gaithersburg single-family homes: dishwashers and refrigerator water lines develop pinhole leaks that go unseen for months because the cabinet walls hide them. A periodic mold inspection with thermal imaging is the most reliable way to catch hidden moisture before it becomes a remediation project.
All work completed in strict accordance with the ANSI/IICRC S520 Standard for Professional Mold Remediation, the same protocol followed on every mold remediation service we perform. Each phase documented with photos and moisture readings throughout.

Porous materials with confirmed mold penetration must be removed — typically drywall, insulation, cabinet backing, and affected subfloor sections. Non-porous materials like countertops, plumbing fixtures, and metal framing can usually be cleaned and treated in place.
Kitchen mold exposure can cause respiratory irritation, allergic reactions, and aggravated asthma — especially concerning because kitchens are high-traffic areas where families spend significant time. Once detected, prompt professional remediation is recommended.
Typically yes, if the leak was sudden and accidental (supply line burst, connection failure) and reported promptly. Gradual leaks from deferred maintenance or worn gaskets may be excluded. Mold Pro provides insurance-ready documentation including photos, moisture readings, and itemized scope.
Install leak detection sensors behind dishwashers, refrigerators, and under sinks. Use braided stainless steel supply lines (not rubber). Inspect connections annually. Maintain adequate ventilation and address any moisture or condensation issues promptly.
