did a nice clean job

Definitely choose Terra Insulation! Josh, Dylan, and Brandon were all fantastic to work with. They removed existing insulation in two attics that was covered in mouse droppings, sanitized both, added baffling, sealed holes, blew in cellulose insulation, and sealed all entry points. They explained all the options and pricing clearly, gladly answered my MANY questions with patience, took care of the rebates with the utility companies, which significantly reduced the total cost, were super flexible with scheduling, very clean, and professional. There were no surprises or hidden costs. I was extremely happy with Terra's workmanship and professionalism and would hire them again without question.

Terra Insulation was great to work with. We knew the upstairs of our 50 year old house was cold and needed more insulation. Dylan came by and after looking in the attic said we needed at least 12 more inches and some other improvements to make a difference. He gave us a quote which was one of the higher of the 3 we got but then told us about the Pepco program that provided funds for improvement. They came out and conducted a blower test to see if we qualified for a energy improvement program. We ended up paying 1/3 of the quoted cost with the Pepco incentive. Out of the three contractors, Terra Insulation was the only one certified and worked with Pepco Home performance ENERGY STAR program. They were fast, completed the project in one day and cleaned up after themselves. We put 1/3 down before the job and when finished we accidental paid the full amount. When we realized what happened we called and they refunded the first 1/3 immediately. Honest and reliable. If you need insulation, you want to call Terra Insulation and ask about the ENERGY STAR program. You won’t be sorry. Thank you Terra Insulation. Our house is much warmer and bills are lower this winter.

Friendly skilled crew. They were efficient and very tidy, despite the messy nature of the work. They took photos of the attic throughout the process. Extremely glad I hired them

I needed a company that would blow insulation into the walls of my basement. Terra Insulation did the job for me. The technicians were expert at drilling the holes, adding the insulation and clean up. They were professional and informed me of when they were taking a break, etc. They even replaced the disks and added drywall paste to ready the walls for my painter. I highly recommend this company for its dependability and expert installation.

They were on time and kept things clean throughout the process. Great bunch of guys. I would use them again.

They took the time to explain the options and inform my decision-making. They answered all of my questions with patience and good humor. I believe I have received great value for the money I have spent. They were flexible when I wanted to make a change once work had begun. Since the house has been air sealed and insulated we have been warm and comfortable. I highly recommend Terra Insulation for your insulation needs.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. 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.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
