Quality of work and efficiency was great. They were simply a little late getting here due to previous job taking longer than expected. Very happy with the result.

Use DEFENDER GLASS BLOCK, you will not be disappointed in any way! SPECIFIC FACTORS WHY: 1. Answers and returns calls/text right away. 2. Owners Zach – dark haired and Luke – wearing hat (pictures attached) extremely professional, great personalities and honest business practices. 3. Very reasonably priced. 4. Measure and installation within days. 5. No extra work, unless discussed with customer prior. 6. Leave work area clean and installation took about an hour for two windows. When I called Zach (pictures included) answered on the second ring. Was out the same day to measure, and by Saturday, Zach and Luke had two glass block basement windows installed. We will use DEFENDER GLASS BLOCK for all our glass block needs. Highly Recommended!

Zach and Luke did a fantastic job! I've got a 100 year old house so no 2 windows were the same size but they handled the challenge! They were courteous, cleaned the job site up and did a fantastic job. I extremely pleased with the work.

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.

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.
