Mold Removal & Remediation in Gig Harbor, WA

My Gig Harbor house is fairly new. Why is there mold in it?

Newer construction does not make a house immune to moisture. Half of Gig Harbor's homes were built in 1996 or later, according to Census-derived figures, and tighter homes from that era can trap humidity from showers, cooking and laundry when fans are undersized or rarely run. Through the wet months from October to April, that moisture condenses on cold window frames, on closet walls along the north side, and on the underside of roof sheathing. Add a slow roof or plumbing leak and drywall and framing stay damp long enough for growth. The age of a house matters less than whether water is getting in and whether it can dry out.

Does living near the bay or on a slope change the job?

It can. The city sits on the shore of Gig Harbor bay, and its critical areas code regulates flood hazard areas alongside landslide, erosion, bluff and ravine hazard areas. Homes cut into slopes may see groundwater pushing through lower walls or collecting in crawl spaces after long rains, while houses facing open water take wind-driven rain on their exposed sides. A capable company traces that water first. If the source is grading or drainage, you may need a drainage contractor as well as the mold work.

How do I know the company is doing it right?

Washington has no state mold license or certification, so check what the state does require: registration with Washington L&I as a construction contractor, which you can confirm on L&I's Verify a Contractor tool. Then look for these steps in the written scope:

• The moisture source is named, with a plan for who repairs it.
• The work area is sealed with plastic sheeting and kept under air filtration.
• Moldy drywall, insulation and carpet are cut out and bagged rather than sprayed and painted over, which EPA warns against.
• Moisture readings confirm the area is dry before anything is closed up.
• Payment follows completed phases, as L&I recommends.

A local note on rebuilding

If removal leaves open walls or damaged framing, the City of Gig Harbor Building & Fire Safety Division issues building permits inside city limits, including repair permits, through its online permit portal. For health questions, the Tacoma-Pierce County Health Department's Healthy Homes program offers mold resources, and the Washington Department of Health keeps a mold page of its own.
