Report
Incredibly fast and efficient. They fixed a main line clog in 5 minutes. Which wouldn't be super impressive if the previous plumber (specializing in drain cleaning) didn't waste two days of work and still wasn't able to fix it. East End Plumbing guys are just great - fast, efficient, friendly. Service: Outdoor plumbing system repair

Report
I had a major plumbing problem and called East End Plumbing Saturday night. I had a return phone call first thing Sunday morning and an appointment scheduled a few short hours later to start to diagnose the problem. The plumber was not only polite but did everything he could to resolve the problem. Unfortunately they had to come back again today to conduct more problem solving. I cannot recommend East End Plumbing enough, they are amazing and do what it takes to get the job done all while keeping their customer's as their number one focus. You will not be disappointed in their service!

I had a leak in my kitchen that resulted in my needing to shut the main water line off. They had someone out to my house less than 2 hours after my call. The repair was fixed in under an hour and the price was less than a competitor's for 'just showing up.' Very professional. For future plumbing issues I know who I'm calling.
