5.0 John J. Hampton, NH

Mike was one time and very professional. Completed the job much quicker than expected. Would hire him again. Will be sending him referrals.

5.0 Earl F. Merrimack, NH

Canâ t go wrong hiring this company. Outstanding service and the job looks great. Spoke to Mike the day before and he was out the next morning on time. Very professional and high high quality work. I will be sending him many referrals over the years and will call him whenever I need something done. I suspect his calendar books up quickly in the spring/summer. I would absolutely 100% recommend you contra t with this company.

5.0 John / laurie G. Amherst, NH

Mike was personable, efficient, and VERY responsive to our needs. In fact, he scheduled and completed the work WEEKS ahead and competitively priced with identicai quality materials to the competition. The work was done efficiently and, best of all, there was not a speck of waste or mess left behind. We would definitely contact and use them in the future if they do the work required.

5.0 Melanie R. Newton, NH

Great work and very friendly. Also very responsive. We noticed an immediate change in temperature in the house. So much more efficient with heating our home now.

3.0 Michael M. Kingston, NH

Nice kid, showed up on time and seemed to know what he was doing but quality of work not great. Cut a $300 corner board 3/8 short, leaving a gap at the top and short on the bottom. Used what looked like a pair of left handed scissors to cut the aluminum and did not follow instructions on part of the job. Refused to split a $300 difference because he did not add correctly on his quote, so in principle, $150 cost him a $4k siding job and other work which looked desperate. The deal he gave me on the work was hard to justify when his quote amount was the same as a 2nd estimate and ultimately paid him an hourly rate most doctors and lawyers would be proud of.

Response from Company:

All of this was discussed in person after the job was completed so it is disheartening that you would take the time to write a review such as this to attempt to create a different narrative. Feel free to contact me directly if you now have issues with the job that you originally assessed and approved so the issue can be remediated!

5.0 Robert P. Epping, NH

Mike was awesome. Professional, courteous, and knowledgeable. Also a fellow veteran. Excellent work!

5.0 Michael B. Derry, NH

Mike was very friendly and easy to work with. He responded quickly and took care of my job within just a few days. After a catastrophic leak in my roof he removed all of the wet insulation in my attic crawlspace And then blew in new insulation. The job was completed quickly I have no complaints at all. I would have no hesitation about doing business with him again.

5.0 Stefanie M. Manchester, NH

This company and Mike are great!! They were able to quote and get us completed prior to winter, at a reasonable price. Very respectful of us and our cat and didnâ t leave anything behind! we have already noticed a difference because the heat kicked on only once last night!! insane what good work can do for your house- highly recommend!

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.

    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)
