Recommended Customer Reviews

I spoke with Norma over a week ago about the issue we were having with our water heater and she quoted me prices on what the job would cost depending on what the problem turned out to be. She even gave me the number for the manufacturer to see if the appliance was still under warranty (which it wasn't). Now a week later I called her back to see if someone could come back to look at it and a technician arrived a few hours later. He was there for approximately 30 minutes, fixed the problem and we were charged exactly what we were quoted! Would definitely recommend this company.

Water heater, brand new, was not working. Called Collier and they showed up on time and very professional. They did a great job, kept it clean and my water heater is working now. Highly recommend they guys.

Elderly abuse company. If you do business watch out. Marian is very rude and obnoxious. Installed a sensor in 5 minutes and charged $165. Sensor was defective. New sensor received under warranty and Collier wanted $90 to install. Rheem water heater rep said too much. Big time rip offs for elderly. Classic case of abuse.

Did not replace the whole valve. They have to sent me a new valve and a new labor code.

I spoke to John on Friday 5/24, he told me I shouldn't worry that my check was stolen out of his truck. My personal information is already on the Internet, so it's not a big deal. Perhaps he doesn't realize anyone can do anything with a routing # and checking account #, let alone my personal information (name & address).
Anyway, please note that when you are paying this company they will keep checks in their vehicle for days until someone safely brings it back to the office. And! If your check goes missing because of their blatant lack of responsibility - it'll be your responsibility to call your bank for a check stop (which they will charge you a fee for) and they'll expect you to drive your happy self to their office to pay them. They will take zero responsibility. They offer no apology, they will simply say it was the ""thief's fault not theirs"".

We bought our home 10 years ago and have been using Collier Plumbing ever since for everything from broken garbage disposal, new water heater, water leaks, hose bib repair, clogged drains, new sinks, etc. I've called around to other plumbers and Collier's rate is always the lowest. Yes, plumbers can be expensive but they are very reasonably priced, quick and always arrive on time. My husband even uses Collier for his commercial business. I'd recommend them 100%.

Called to schedule an appointment to come the next day & estimated 3-4PM it is now 6:30PM & they never came. Guess they don't want business? Called and they never picked up.

If you want a company that has great response time and honest quotes, then this is who you want!
My 9yo water heater pilot light had gone out and it wouldn't stay lit. We called a company based on Yelp reviews, they came out and basically said he didn't have any parts IF the thermo coupler was the problem. Otherwise we might have to replace the whole thing... got quoted at $350 to fix and up to $2200 to replace the whole unit. I said NO WAY...BYE!
I called Collier and they were out within 2 hours and the technician, Austin, determined within a minute that it was the thermo coupler and he replaced it... within 15 minutes! And at a great service fee, plus $15 for the part! Norma in the office was great! Austin was awesome! Thank you, thank you, thank you!

Prompt response time was appreciated for our water-heater repair. Great service provided by Dylan! Price was what was quoted originally. This is true Plumbing professionalism. We will use this service again if faced with any new issues.
Thanks again for the service.

My favorite plumber in the area! Professional, friendly, fast, prompt and very reasonably priced. I've worked with John and his friendly staff for 15 years now and I have always been given the best service every single time! HIGHLY RECOMMEND!
