From first estimate visit to final project completion, Fairfax Insulation Systems demonstrated superb customer service and trustworthiness to do the job right. I am very pleased with their work and would recommend them to anyone who wants a straightforward competent company working in their home.

Fairfax Insulation just completed a job for us and I cannot say enough good things about them. We had a bathroom remodel scheduled and got short notice that our contractor would start in a week, and we had to get the spray foam insulation right after the demo so they could put the walls up without delaying the job. Our spray foam insulation contractor couldn't get us scheduled on such short notice. I contacted every place I could find that did spray foam insulation and Fairfax Insulation came through for us on very short notice. Will came out, was very nice and professional and gave us an estimate and got us on the schedule the day we needed the work done. After the demo, we discovered some problems inside the walls that needed more insulation, both sprayed and batting. Will came back that day, measured everything again and adjusted the estimate. The following day, Pedro and Marbin came and did the spray foam insulation. They were very nice and professional, did a very good job with the spray foam coverage and left the area clean. They had to send someone else to install the batting insulation so they squeezed us into their schedule to have that done. I received a call from Juan Cruz, who would come to install that. By the time he completed his regularly scheduled jobs, it was 6:30pm, but he came out from DC, was very polite and professional, and did an excellent job completing and securing the insulation. We are very happy with all of the people with Fairfax Insulation and would highly recommend them.

Workers showed up on time, they did the job but I had to be behind them to clean but my problem is the job completion paperwork that I have asked for, they have not provided to me.

5.0 Robert T. Round Hill, VA

They (Rauol andWalter) we’re great! Showed up on time, took great care of all areas of the house, did what the contract specified. We are very pleased with the look of our attic and look forward to the $$ saving in heating and cooling for years to come. The tent and baffle placement as well as the blown in insulation materials will serve us well in the coming years. Thanks for the great job!

5.0 Tm H. Fairfax, VA

Fairfax Insulation Systems LLC did an excellent job of removing old blown-in, sanitizing, sealing, adding baffles, and installing mineral wool bait in attic. The cleanliness and professional job received from this crew is highly recommended. They provided photos throughout this insulation process. Treating others with respect and appreciation works both ways. Great job!

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.
