I called about a leaky valve under our sink. Bill, despite being very busy, sent Jesse out to our house. He was extremely professional, friendly and knew what the problem was within minutes. The repair was done and the price was very tolerable. I can't recommend this company highly enough!

A concerning review from an experienced renovator.
1. Quote was reasonable
2. Invoice was 65% higher than quote for a straightforward job
3. One man job but two men did the work (can live with that)
4. Actual time in my residence was 3.25 hours. Was billed for 5 hours.
5. Did not arrive with any parts so you would think they would send the 1st year apprentice to buy them while the journeyman starts work - NOPE they both go for parts; thereby costing me 45 mins in labour charges for a parts pick up that they should have already. Was not a unique job.
6. Back to the parts. They used five basic

Amazing experience! We had a major flood and had to turn our water off. This was the only plumbing company that could come quickly. Two great guys came and fixed the problem in a matter of minutes and the price was more than reasonable. Highly recommend!

Wow, what a gem of a repair place! We brought in our Hayward pool pump to be fixed on the recommendation of our pool store. Bill not only looked at it and fixed it while we talked to him but also problem solved other questions we had about the pump leaking etc. He put a new cap on it and replaced some screws free of charge. We walked away in 15-20 mins with a fixed pump, proper cap to stop the leaking and so much knowledge, all for $20!!! We will be going there for more than just pool pump needs in the future. Highly recommend this place!!

My landlord uses this company, and every time Ive had to call them they would come out (worker is very young) attempt to look at the issue leave for another week or so and in the meantime lied to my landlord about what needs to be done yet when face-to-face claims they did not say that.
Ive had issues with my tub and each time takes well over a month for a 10 minute unclogging job. This time because I own a mastiff mix puppy, the worker refused to even step anywhere near my apartment Door. And was very belligerent and demanding to crate my dog, not just put them in my room but a crate
