5.0 Marilou O. San Francisco, CA

They were very pleasant to work with. They communicated with me and kept me in touch with updates on the work to be done. They were understanding when things came up before work started. They were courteous and thoughtful when it came to dealing with the customers they have. I highly recommend Cota Glass!

5.0 Andy M. San Bruno, CA

Excellent work!

5.0 Jeffery Gersick Google Review

The seals on some of our Insulated Glass slider windows had failed, causing several to get cloudy and stained between the two layers. I like to support small family businesses so chose Cota Glass, and was rewarded by Ryan doing a first rate job in replacing the panes. Rapid, reliable, moderately priced and flawless installation performed by an affable professional - what more could you ask from a company?

4.0 Roger L. San Francisco, CA

Ryan did an excellent job. He replaced a broken pane, left the place perfectly clean.

5.0 Andreas Djokic Google Review

We're incredibly happy with the help and work Ryan provided! We called initially to help investigate a potential leak in our older windows. He identified issues with a hastily done paint job on top of the older caulking, and helped re-open and patch up/caulk the exterior in no time. He then helped investigate the interior (and even checked our attic to see how the insulation might affect the humidity and condensation we were seeing on the windows), and provided some incredibly helpful recommendations. He was very easy to work with, and his wife Albee helped make coordinating a breeze! They provided an initial inspection and a quote, while making sure we were on board with everything and on the same page timing wise. Would highly recommend!

I am so glad we found Ryan to restore the original wood casement windows in our 1926 home. It’d been difficult to find a craftsman for this type of job. They had gaps and misalignment (with visible light!), were unable to close securely, and letting in drafts. Scheduling and communication with Ryan and his wife/business partner Albee was so easy. Ryan was able to give us a clear estimate and returned to complete the project in one day. Each window is now fully functional and more importantly, weather tight! Ryan was meticulous in his attention to detail and thoughtful and considerate of his workspace and our home. I couldn’t recommend him more highly and plan to hire again.

Ryan did a great job with our drafty and leaky front wood windows and turned a fixed wood window into one we can now open. He was a joy to work with and the results are fantastic.

5.0 Joel A. Google Review

Ryan cut and installed a large frameless shower door for my master bathroom and did an excellent job. He's personable and thorough with his work. I would hire again.

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.
