Mr. Elsayed is Unbelievable. I check all 5 items. Couldn't ask for a more professional plumber. I ordered the wrong kitchen faucet. We went to The Home Depot to return the wrong faucet I bought. Mr. Elsayed new exactly which faucet I needed. Installed new faucet. Works great. Also, he is a VERY safe driver…
I had three things to take care of and he did them all efficiently. He showed up early-- which I requested--and got to work right away. I'm very pleased with the results.
Wow, Elsayed is the best contractor I've ever worked with in Boston. He came on a Monday to quote a washer/dryer plumbing project, took detailed measurements, asked great questions, provided a competitive, straightforward quote, and did the work on Thursday morning of the same week. I got 4 other quotes for this project, and not only did he have the best price, but he quoted doing it right rather than an easier / lazier way. High quality workmanship, incredibly kind man, and I cannot wait to work with him again. For anything plumbing and electrical around the house, OSA is the best choice for anything plumbing and electrical around the house, OSA is the best choice.…
The technician was extremely careful not to track dirt into my house. He fixed the leaking sink for both bathroom quickly and left the bathroom cleaner than he found it. Highly recommend for anyone who values a tidy workspace & respectful professional.
Good construction company.
