William was great to work with. Came in originally to get my garbage disposal to be replaced and noticed there was a clog with the pipes. He was able to snake the piping which helped unclog whatever was blocking the pipes. He cleaned up after himself and was considerate of cleaning up the mess he made. Would highly recommend.

Details: Yes, the existing disposal needs to be replaced • Continuous feed (most common) • Yes I will provide the garbage disposal

William was prompt and on time, and he did a great job replacing our toilet. He also took the time to look at our shower lever—while he couldn’t fix it right away, he explained the issue and offered to help us find the replacement part. Professional, honest, and helpful! We will definitely use him again and recommend him to others.
