BELFOR Property Restoration | Damage Restoration & Mold Remediation in Seattle

In Seattle's damp climate, HVAC systems produce more condensate than in drier regions. When the drain line becomes clogged with algae, dust, or debris, or if the drip pan cracks, the overflow can saturate ceilings, walls, and flooring. This is especially common during warmer months when air conditioning runs frequently. If left unchecked, the moisture can lead to mold growth within 24-48 hours.

Signs of a slab leak due to freeze-thaw cycles include unexplained warm spots on the floor, a sudden increase in your water bill, low water pressure, or the sound of running water when all fixtures are off. You might also notice cracks in the foundation or damp areas on flooring. In Seattle's winter, repeated freezing and thawing can cause pipes under concrete slabs to rupture, leading to hidden water damage.

After an appliance leak like an HVAC overflow, the first step is to stop the water source and dry the area completely. BELFOR then conducts a thorough inspection for mold, using moisture meters and thermal imaging. Mold remediation involves containing the affected area, removing contaminated materials (like drywall or carpet), cleaning with antimicrobial agents, and ensuring proper ventilation. Finally, we apply sealants to prevent future growth and restore the area to a safe, healthy condition.
