Mold remediation in Portland typically runs between $1,200 and $3,800, depending on how much of your home is affected and how deep the problem goes. Older homes like many in Portland (the median house here was built in 1950) are especially vulnerable, and our wet climate doesn't help - the area gets about 47 inches of rain yearly. When you're shopping for a contractor, you'll want someone who carries proper insurance and holds a relevant contractor license. Look for IICRC S520 certification, which shows they know what they're doing, even though Maine doesn't require a specific mold remediation license.
Mattra Inc. is a mold remediation contractor serving Portland homeowners dealing with this issue. Before you call anyone, get a few quotes so you understand what you're paying for. When you talk to Mattra Inc. or any contractor, ask them to verify their insurance coverage and whether they hold that S520 certification - it's a straightforward way to confirm they're qualified for the job.
