Hired on Thumbtack

Sayed was absolutely amazing. He was incredibly friendly, knowledgeable, and took the time to recommend the best solution for my needs. He went above and beyond by thoroughly checking for leaks and ensuring everything was perfectly sealed before finishing. I truly appreciate the attention to detail and high level of service. Highly recommended!

What a pleasure to work with Sayed. He is thorough and does impeccable work. He helped replace 2 toilets and repaired other related components. He explained everything and cleaned up well afterwards. Sayed is a gem!

Sayed has fixed some plumbing issues in my bathroom. He was very professional throughout, explaining clearly what happened and how he was going to proceed. He was ponctual. Actually, even early than appointed. I would definitely recommend his services.

Sayed was kind enough to come on Easter to replace the toilet fill valve. He came on time and worked quickly. Thank you, Sayed.
