Our project was installing gas lines in an existing house along with an on demand water heater and gas stove. Home advisor doesn't have categories for gas so the type of service is not quite right and it was hard finding someone to do the work. I can't say enough about FOSS' professionalism. Mark impressed me with the bid by crawling through every nook and cranny in the house to evaluate how the installation would be done. I had one other bidder who was a slight bit lower but the evaluation was not nearly as detailed and they were going to hire other contractors with no firm price. When install time came FOSS worked around the gas company meter install and the first day the owner came out to assure the install would be the best possible. He had changes made to make the exterior install look as good as it could. It looks fantastic. Far better than I had thought it would. They handled everything, including electrical, plumbing, cement drilling and painting. These guys are very professional and I highly recommend them. I will be using them for my regular annual maintenance too.

The representative explained everything throughly. We were given all the details up front and he helped us make the right choice for our home. The installers were very efficient and fast. We would recommend them to everyone.

Project: Install Electric Furnace / Forced Air Heating System
They had a very good sales; prompt, efficient and comprehensive. Work crew was hard working w/ a good sense of humor. And the Tec was just the same. Foss is exactly what you expect when you hire for this type of 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.

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.
