Mr. Harwood arrived on time, assessed the situation, fixed the problem, and then for no extra charge inspected the rest of my house, my grape arbor and my detached garage, finding and repairing two additional termite sites. He was very low key, straight forward and his charge was reasonable. He seemed to be very experienced and found termite holes I hadn't ever noticed.

I can't say enough good things about Doyle. Within minutes of booking an appointment through Home Advisor, Doyle called to confirm, and to obtain more information about my situation. He was prompt for the inspection appointment, and even early for the actual treatment appointment. He was very thorough in both the inspection and treatment, he explained everything very clearly, and unlike every other termite professional I had encountered over the past 22 years, Doyle did not try to up-sell us on services we didn't need. His extensive experience was very important, since the infestation was in a bathroom, where the risk of drilling into a pipe was high. He knew how to avoid the plumbing and drainage pipes, and his work was clean and careful. He also used a highly effective pesticide (Termidor), ensuring that the treatment would be as successful as possible. Doyle noticed that our backyard sloped towards the house, placing us at greater risk for subterranean termites during periods of heavy rainfall. He gladly took the time to discuss possible remedies for us to consider, and made recommendations that we could easily do ourselves. I am very thankful to have finally found a termite professional who is very honest and professional. The price he charged was very reasonable and worth every penny. He charged but a fraction of what the other companies have charged us in the past for similar services. As another reviewer noted, "Call Doyle he will take care of you! You will be satisfied"

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.
