5.0 Liz R. Newburyport, MA

All excellent

5.0 Zoni W. Lynn, MA

Very prompt, friendly and efficient. They did an inspection and gave me some advice that I didnâ t think of.

5.0 Sharon W. North Reading, MA

Ants had moved into our kitchen wall and were invading our food cabinets. Cornerstone responded to our call right away and we got an appointment quickly. Within a week after treating the countertops with gel (toxic to ants but safe for people/pets), as well as the foundation outside, we are happily ant free.

5.0 Collette D. Hudson, NH

They were prompt, polite, informative, reassuring and reasonably priced. Not only did they take care of my carpenter ant issue but they also addressed my mice issue with boxes on the outside of the house. The whole process took less than an hour and now I can sleep again without poison in my hands ready to strike. And it's consoling to know that they will be here every three months during the year to make sure that these menacing bugs aren't still bugging me. And If you divide the total bill , the cost per day is only $1.37. Works for me! ð ð . You're the best !

5.0 Paula B. Groveland, MA

They were prompt in getting back to me. I have a severe bee allergy and with a massive nest in our attic, I was afraid of getting hurt. I reached out on a Sunday and they called me within an hour or so and they were at my house the next day as promised. Very reasonable pricing and very kind and thorough. They answered all my questions and I would highly recommend them to others.

5.0 Paul B. Wakefield, MA

So far they deserve five stars.

5.0 Cheryl H. Pelham, NH

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

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.
