In Business Since 1994

Mold. Insulation. Air sealing. Energy. All under one roof ? because these problems are connected.

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.

How We Got Started

I chose to work in this industry because We saw too many homeowners paying for fixes that didn't last because nobody took the time to figure out why the problem was happening. Over 30 years ago, we started Mattra to change that — diagnose first, then fix the whole system, not just the symptom you can see..

We started in this industry in 1996.

We describe our business as Family owned and operated

What makes Mattra Inc. different from other contractors?

We connect mold, moisture, insulation, and air movement as one system — because that's how your home actually works. Most contractors treat one symptom. We find the root cause and fix the whole picture under one roof, backed by over 30 years of building science experience. If you don't need something, we'll tell you that too.

Install Spray Foam Insulation

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.

Find More Pros

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

To find more licensing information for your state, visit our Licensing Requirements page. Note that some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

HomeAdvisor's Screening Process

HomeAdvisor uses an extensive screening process to screen businesses and business owners/principals. We perform this screening when a business applies to join our network and, if the business is accepted, whenever concerns are brought to our attention. If you have concerns that a pro in our network doesn't meet these standards, please contact us to investigate. We're committed to maintaining a network of trusted home service businesses, and those who don't meet our criteria will be rejected or promptly removed from our network.

Criminal Background Check

Who does HomeAdvisor background check?

The owner or principal of each business in HomeAdvisor's network (with the exception of Corporate Accounts) must pass a background check. Unfortunately, we cannot perform a background check on every employee of a business—the background checks are performed only on the owner or principal. As always, we recommend that you conduct your own research on the businesses you hire, including making inquiries directly with the businesses regarding their employee background check policies.

What does the background check cover?

We use a third-party vendor to conduct a criminal records search in the county in which the business owner or principal works. Our third-party vendor uses a national criminal database ("NCD") to screen service professionals. Business owners or principals with felony arrests that carry a pending decision or who are convicted of felonies in the past 7 years ago will not be admitted to the network. Businesses or owners convicted misdemeanors or felonies, or who have dismissed charges or arrests on their records involving rape/incest, sex offenses, or lewd and lascivious behavior at any point in time will not be admitted to our network.

Our background check does not exclude service professionals unless the crime at issue is a felony.

*The comprehensiveness of the NCD varies by state. Please be aware that the reporting in the NCD is particularly limited in the following states: AL, CO, DE, GA, ID, IL, KS, LA, ME, MA, MI, MS, MT, NE, NV, NH, NM, SD, UT, VA, VT, and WY. After initial admission to the HomeAdvisor network, businesses are re-screened if a concern is reported to HomeAdvisor.

Corporate Accounts

Some businesses are employees, franchisees, dealers or independent contractors ("Corporate SP's") of larger national or "Corporate Accounts". When this is the case, we may match you with the Corporate Account or with one of their Corporate businesses. The above screening process does not apply to Corporate Accounts, as HomeAdvisor does not screen Corporate Accounts or Corporate businesses.

Verify Trade License HomeAdvisor checks to see if the business carries the appropriate state-level license. Verify Insurance As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services. Verification of State Business Filings For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located. Criminal Records Search HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business. Sex Offender Search We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located. Bankruptcy Search We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them. Legal Search for Civil Judgments We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them. Liens Search We use 3rd party data sources to check the principal/owner of the business for liens placed against them. Identity Verification (SSN) HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities. Identity Verification (Reverse Phone Lookup) We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
