About us

Most contractors jump straight to the fix — spray something, install something, and move on. When the problem comes back, you're left wondering what went wrong. Mattra Inc. starts with a free expert inspection. We come to your home, assess the situation, and walk you through what we're seeing — so you understand the problem before anyone talks about solutions. If deeper diagnostics make sense, we'll explain why. If they don't, we'll tell you that too. We handle the full scope: mold remediation, insulation, air sealing, energy audits, and rebuild when needed. BPI Certified. Efficiency Maine Registered Vendor. Over 30 years of experience. Whether the project starts with mold, moisture, or energy loss, the work that solves the root cause often qualifies for Efficiency Maine rebates. We handle the paperwork. Based in Lewiston-Auburn, serving homeowners across Maine. Call to schedule your free inspection.

Spray Foam Insulation Installation
Without a doubt, this one of the best, if not the best, companies I have contracted with recently. They present with honesty, integrity and a performance that is reliable and efficient. This company has something very special going with their employees. It has been a true pleasure to work them. You will not go wrong doing business with them.
