Recommended Customer Reviews

The tub faucet leak has bothered me for a long while. I have had two plumbers come but no fix. Finally I found United Plumbing. They were very
responsible, fast and professional. Alex spent a lot of time finding the matching part but it did not work. They followed it through the next morning
with new parts and fixed the problem quickly. They have an excellent team work and expertise. I am very happy with their 5-star services and would recommend them to everyone! Thanks so much for fixing my problem!

Just because they have a contract with Hague Quailty Water, doesn't mean you'll get quality work! We had United Plumbing Contractors (Hague Quality Water of Los Gatos) install our system many years ago and we have always ""had"" to use them because I didn't realize there was someone else to use instead. I've had questionable service over the years. There are several problems with HQW of Los Gatos 1) Kim doesn't return phone calls in a timely manner. 2) They overcharge customers! This last time, I needed my unit serviced. I was told it was going to be over $500 for the RO filter changes, a check on the water softener and as well as a flush on the water heater (We just had our house repiped and I wanted it to all be working with the new pipes). When Kim didn't return my calls, I looked on Yelp, and found a different authorized Hague dealer and called him. He returned my call in less than 2 hours, scheduled an appointment within days AND today, when they finished, my bill for the exact same thing was MUCH LESS! Won't be calling UPC ever again! Trust in UPC was waning, but now it's gone gone gone!

I was compelled to write this. They wouldn't provide me with a written bid or quote. I was bullied, harassed, intimidated and disrespected by email and text. I called office manager and owner and emailed the owner contractor.. I never received any acknowledgement.nor an apology for horrible treatment and experience. They don't care about you as a customer. I would not recommend working with Troy Burchby. They wanted to charge me over 700.00 above what the job was for. . Always get your bid and work in writing.

I was very disappointed with their service. They over charged me even according to their written invoice. They broke things. They promised to pay me back for the extra charges on the new service. They said they would come and give me bid for the new service but they never came back. I went with another company for the new service after waiting for them call.

Avoid At All Costs.....
(this was also posted at Hague - Los Gatos)
We sold our home in south San Jose, but before the title changed hands, we needed to get a permit for our water heater and water softener. Who knew?
Since the softener was originally installed by Hague shortly after our place was built in 2003, we called them. Too bad I didn't read my own advice from October 2017.
Long story short.....We mostly spoke with Kim in their Los Gatos office. However, the job appeared to be outsourced to United Plumbing Contractors in Campbell. Cody, a nice and relatively young guy, came to our house at the appointed time and dealt with my wife since I was at work (although she called me with all big decisions).
Listen to this: For the water softener to pass inspection and gain a permit, they claimed it needed to be vented from the garage (where it sat) through the roof. That's 2 floors and an attic above the garage...at a cost of ""a few thousand dollars"". I told Cody to take the softener out.
There's more: For the water heater, Cody (or the person he was getting instructions from. He was on the phone many times with his home office), said we needed to attach a separate piece of equipment at a cost of ""several hundred dollars"". ""You need it to pass inspection"". We're not plumbers so we said yes.
And more: At least a week after the work was done and bill paid, Kim said ""Cody didn't have all the insulation needed for the water heater when he worked on it. He'll come by tomorrow. Should only take 15 minutes"". He came and charged $50 plus $10 for material. Would it have cost less if he did it the first time?
I wasn't even going to write a review, but we just had our final inspection. The verdict? Nothing needed to be done to the water heater to pass and get a permit. The softener? To quote the inspector...""I've never heard of the need to vent through the roof. You had a perfectly good softener and now it's gone"".
Maybe we misunderstood the recommendations, but isn't it better to play it safe? Go somewhere else.

Excellent service today. Found leak in sink and fixed my faucet. Arrived on time. Plumber was extremely nice and helpful.

UPC got to us through a call we made to our home warranty to replace the pressure valve. they quoted up to $500 for us to pay out of pocket ""to be safe since the job might include access work up to half a day"".
They ended up not needing to do all this access work. the whole job took less than 1.5 hours. Nonetheless, they took advantage of my wife being home alone to wait for them and charged her almost $500 on top of the $300 the warranty paid.
I called and talked to Kim who promised to look into this and call me back ""Monday"". Never heard back. I called 4-5 other times over a few weeks and left messages. Never heard back. Their mailbox is now full and not even receiving new messages. Not sure if they went out of business or just ignoring their customers across the board now.

(I posted this review for Hague Quality Water as well, because I believe it's the same company that did the work described below)
I have been impressed from the second I've been in touch with United Plumbing Contractors. We had a backup in our cleanup that they came out and diagnosed to be pipe misalignment at a connector (from a previous cleanout installation). They were able to come out the next day to do the repair work (a LOT of digging) and did an outstanding job.
Every single person I've dealt with at Hague has absolutely been phenomenal. Kim, Christian, and Casey were friendly, prompt, explained everything I needed to know, and answered all of our questions.
They've made a new customer for life.

Pete and the UPC team did all our custom plumbing for our kitchen remodel, bathroom addition and later, our utility room renovation. We were very pleased with the work. Quick, professional, punctual, and fair prices.
When we had a leak from our old galvanized pipes on the side of the house that was not updated, Pete came out the same day, crawled under our house and fixed the problem and with a fee that was way below what we expected.
When we had our reverse osmosis (RO) filter changed with Hague, there was a big leak all behind our cabinets and leaked through the floor and into the kitchen. Hague came after 4 calls or one call to Pete. I'm still unclear if Hague Water Quality and UPC are the same company.
We had another unrelated clog in the RO system and we texted Pete to have it looked at and he had Arthur out in an hour to repair it. The RO system gives us the best tasting quality water with our highly mineralized tap water, but has given us more problems that we would like to deal with. Luckily UPC is very responsive, fixes the problems quickly, and with excellent customer service.

Had a leaking water heater needing replacement 5 yrs into 6 yr warranty. Called the original installer who quoted close to the price of a new water heater to replace this under warranty. Looked at other dealers for this AO Smith unit and found UPC. I called them and they were very helpful, making a service call and quickly getting me a fair quote for replacing the heater under warranty, no charge for the inspection visit as I agreed for them to do the job. As soon as they got the replacement heater in, they came out, got the whole job done in 2 hours, doing a top job of cleaning up afterwards. Very polite and thorough, showing excellent craftmanship in the copper pipe sweating etc. Out came the bill and they charged me at the low end of their quote range. From front office communications to the job site work, these guys impressed me and I would definitely use them again if need arises.
