What customers say about Octagon Cleaning & Restoration
Octagon Cleaning & Restoration holds a 4.7-star rating across 190 Google reviews, which is solid validation in a region where mold risk runs high. Portland's climate - 72% average humidity and 47 inches of annual rainfall - combined with the median home built in 1950 creates ideal conditions for moisture problems. That track record suggests the company has handled the kinds of jobs that matter most to local homeowners dealing with older properties in a damp environment.
Before you call, understand that Octagon is listed as a mold inspector, which creates a potential conflict of interest under industry standards - the same firm profits from finding problems and then fixing them. Maine doesn't require a specific mold remediation license, so verify the contractor holds a relevant state license and current insurance. Ask whether they hold IICRC S520 certification, the recognized standard for mold remediation professionals. A standalone mold inspection in this region typically costs $200-$600, so get that quote upfront and consider getting a second opinion from an inspector who doesn't also do remediation work.

Note: may also offer remediation services
This company's listed services suggest it may also perform mold remediation — confirm directly before booking an inspection. Industry standards recommend using a separate inspector and remediator to avoid a conflict of interest: an inspector who may also profit from remediation has less incentive to give an unbiased report.
