Great service to estimate cost, clear cost outline, and fast, quality work. Post-service communication has been good after a few reschedules. The owner really takes good care of his customers and cares a lot. They run a solid operation.

I wish I had snapped photos during the process to show you how clean and sanitary and professionally this company works. The crew arrived at exactly the right time as promised and lined their trail with either paper and plastic to seal off rooms. They went into my attic and found that the previous company had not done what they were supposed to have done And took photographs of it for me. I’ll deal with that at another time. They sucked every bit of old insulation out of my roof and it was spotlessly cleaned and sanitized , then they installed new insulation and I have over 50 recessed lights and they carefully enclosed each one and sealed with foam. every screen was replaced to make sure that no rodents could enter through my attic. Under my home, they dug next to my foundation 14 inches deep to be sure that no more rodents could tunnel under the foundation they installed wire and bolted it to the foundation. My project was done with scrupulous attention to detail, and Axel will return to my home next week to pick up the traps that were left in the event any rodents were captured in the house during the sealing. The communication with Rywen is exceptional. As for Price, it is fair for the quality of work that they do. I can’t wait to sleep through the night without hearing rats, digging under my house! I feel this is a tremendous upgrade to my home, and I have terminated my monthly rodent contract contract, which did absolutely nothing for controlling rodents!

Tony Galicia inspected our house after we found a dead rat in the crawl space. He found another rat in the attic. Both rats died several weeks ago. Tony was diligent and thorough, looking for how the rats could have accessed those spaces. He proposed a second inspection with a small crew to try again to discover the rats’ entry points.

I was very pleased with the attention to detail and workmanship that Rywen has given to the project. Rywen was very knowledgeable about the process and did an excellent job repairing the exterior siding on my home.

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
