This pro was thorough and seemed extremely knowledgeable. He explained everything to me in detail. He was professional and followed through with everything he promised. He was a pleasure to deal with. His price was fair. I have no complaints and strongly recommend him.

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.

Literally went out of his way to help me. Did a great job, was friendly, respectful, punctual, professional, and was able to do an add-on request I needed as well! Very happy with his ability to work with me and get the job done.

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.

OSA construction went above and beyond on my bathroom project. They built my bathroom from scratch and they did it in two weeks. It turned out amazing. They did it in a small space and at a great price. They also added details to accommodate my needs to maximize my space. I can not wait to use them on my next project!
