Square One Home Inspections, LLC. - Home Inspections and Radon/Water Testing

Square One Home Inspections, LLC holds a 5-star rating across 770 Google reviews, which carries real weight in Portland's challenging climate. With 72% average humidity and 47 inches of annual rainfall, plus a median home age of 1950, mold and moisture issues are genuine concerns for local homeowners. That consistent five-star track record suggests the company has earned trust handling the exact conditions that plague older Portland properties. When you're evaluating inspectors in a region where water intrusion is common, a long list of satisfied reviews is a meaningful signal.

Before you hire, know that Square One is listed as a mold inspector - and this matters. Industry standards flag a conflict of interest when inspectors also perform remediation work, since they'd profit from finding problems. If you need a mold inspection, verify the inspector holds IICRC S520 certification and carries appropriate insurance. Maine doesn't require a specific mold remediation license, so contractor licensing and insurance are your main safeguards. A standalone mold inspection in this region typically costs $200-$600; get that estimate upfront and confirm the inspector isn't also bidding on the fix.
