Dempster Plumbing

We found Bill Dempster using Yelp. He came in for what we thought was our kitchen sink clogging up. It ended up being a much bigger problem. He made time in his schedule to come back the next day will all the equipment and piping that was needed and fixed the issues. We haven't had a clog since.

Since this was so unexpected, he gave us a good deal. I will definitely call him for any future plumbing needs.

I'm a real estate broker and have gone through a lot of plumbers. Until now, I haven't been able to refer any plumbers out to my clients because there wasn't any one that I could trust.

Then, I was recently referred to Bill Dempster and his team by a client of mine. I was so impressed with the quality and finish work in my clients bathroom (which was practically a full remodel) that I called him to open up my bathtub walls to check out some water damage and install a shower enclosure. They did a great job of identifying the problem, salvaged the marble tiles and did a beautiful job patching, sheetrocking and reattaching the marble.

They also did an amazing job putting the enclosure on. I have seen so many shotty jobs that I know it's not as easy as it seems. His team even noticed that the new glass door was slightly chipped so they took it back to Home depot for me and got a new one and the installation was spot on!! They vacuumed and cleaned and it was like they were never there! Thanks Bill, Vallen and Brian!! You guys are awesome!

Recently, I just sent him to quote out another clients home of mine and he was very professional with the seller and gave me a fair assessment (even showed up before I did!) He returns your calls and shows up on time and does a superb job!

I called Bill for a leak. He said all the pipes were ready to go and we needed a re-pipe (the house had old galvanized pipes). Before I hired him, I got estimates from other plumbers. They confirmed his assessment, but he was much more thorough than the others.

Then I called many of his references (I found Bill through Yelp). All of his references gave glowing reviews. Several were property managers, so they've worked with him on multiple jobs throughout the years.

When you find a good contractor, hang on tight'; they're difficult to come by. Bill and his team are these rare gems. They take pride in their work, their prices are excellent, and the whole process of working with them has been a pleasure.

I can't recommend Dempster Plumbing highly enough. I'll definitely have Bill do any plumbing and bathroom remodel work in our next house.

Work performed: full re-pipe, retile of two bathrooms: floor and shower & tub/shower. Oh, and they fixed our front door and tightened a loose faucet while they were here--free of charge.

My water heater recently started leaking, and after contacting my home warranty company and having a bad experience with the plumbers they referred, I decided to contact Bill, who I found through yelp. Since he had the highest reviews, I decided to give him a call about replacing my water heater.

I found that he was very knowledgeable and thorough about my inquiries about a tankless vs. tank water heater. I ended up going with a standard, tank water heater which he installed at a very competitive rate. Him and his crew did a very thorough, clean job.

I had no problems with setting up an appointment with him or getting my questions answered. He was always very quick in responding to both emails and phone calls.

I would highly recommend Bill for his exemplary customer service attitude, knowledge, and his ability to get things fixed quickly.

We found Dempster Plumbing online--nice site, good reviews, and the option to contact by email...very cool. We'd already had poor service with two previous plumbers/contractors trying to fix a bad leak in one bath (draining into our living room) and a broken/leaking shower handle/spout in the other. We had drywall damages too and we'd already spent over $750!

Bill, Vicente and team did a really great job. Not only did they do exactly what they said they would, but they kept their appointments, moved quickly and even took compassion on our situation--giving us a really good price with a free shower part and some free drywalling repairs to boot!

We are really pleased with the work--no more leaks and all the drywall is repaired--even textured to match for when we repaint. Bill is the real deal and we are so glad to have met him. Thanks, Bill and team!!

I found Bill Dempster though a recommendation from a co-worker, and after reading the existing reviews here and on on Angie's List decided to talk to him about my re-pipe needs. He was quickly able to set up an appointment, and gave me what I believe to be a reasonable quote for the work.

He and his team did a wonderful job with the re-pipe, and quickly corrected the few problems that were discovered (one caused by an earlier partial re-pipe of the home). They kept the site clean, both by tarping all areas of the house they entered and by sweeping the garage after every day. The drywall they had to remove for their work is almost surgical, and even though they were not contracted for the drywall repair, they replaced all but one piece that was too damaged to re-use (prior water damage in the bathroom). They made sure I had water every night, and even repaired my dryer vent for me while they were under the house. They also replaced a shower valve at my request and neatly dressed the water filter lines under the kitchen sink. The re-pipe and tankless water heater install went well and on schedule.

I highly recommend Bill and his company, and would definitely use him for any plumbing needs in the future.

I suddenly noticed that water was dripping from my kitchen ceiling. I called Bill and he said he would drop by in a couple of hours. Bill then called saying he would be late. While he did keep me waiting for a long time, atleast he called to inform saying he would be late.
Bill came in and looked at the ceiling and my master bath tub above. He immediately noticed that the problem was that the overflow valve was loose. He tightened it and tested it to ensure that there was no other leak. I was mentally prepared for big repairs and was agonizing all day. Bill was extremely honest and only charged me for gas to get to my place.

Update to the previous review - After my first experience with Dempster plumbing, I called them back to replace a toilet. This is supposed to be a fairly simple project - Bill sent an assistant to fix the toilet. He did a demo on the toilet and left. I tried the flush again and noticed a leak - so I called him back. He came back immediately and fixed the leak. A few weeks later I noticed that the ceiling on the level below had a water stain. Furious I called again. They were very professional and said they would fix the toilet and the ceiling below. They handled it very well - no complaints on the way it was handled. A few weeks later - I notice the leak again. This is my guest bath and isn't used often - so I didn't even notice it. I called him and once again someone came to fix the job.

In summary - they handle issues well but there just shouldn't be so many issues with a toilet being replaced.

Bill Dempster and his crew repiped our entire house, replaced the 40+ year old water heater and installed a booster. He did all this in under two weeks and with little disruption to our daily lives. He was always professional and kept us up-to-date on the progress. After calling three other plumbers who told us they would not undertake this project, Bill agreed to go forth.

We never could have imagined the difference the work Bill did would make such an impact on our lives! Our water is running through clean pipes, and we can flush the toilet, run a load of laundry and shower all at the same time! This is important for a family of five!

Bill stands behind his word and immediately came to our home and free of charge replaced the booster when it stopped working. His crew is polite and hard-working. They show-up when they say they are going too.

I highly recommend Dempster Plumbing.

I had been using a seemingly professional, but unlicensed, contractor to add a 1/2 bath in my 1908 Victorian home near downtown San Jose. He originally told me that the entire job would take approximately 7-10 working days. Fast forward 7 weeks! The job was at his pace at least 2 weeks to completion, over 3 times the original timeframe. ""How can that be?"", you ask - because almost every task he did, he did wrong, and then he had to re-do the work! I was beyond frustrated and had already paid the guy $5500 of the $8K I agreed to, but the one thing I knew for sure was that the utilities had to be right and had to be to code. This contractor did one thing or another to the plumbing on at least 5 separate occasions and each time there were leaks, missing or incorrect straps or non-level pipes and he had to re-do it in an attempt to get it right. I had enough of this guy with his excuses and shoddy work, so I found Dempster Plumbing in an on-line review. He was a licensed, bonded, and insured plumber and he had 20 reviews that were 5 out of 5 stars. Could this guy help me out? Well let me tell you - all I can say is ""Incredible!""

I called Bill Dempster, the owner. He returned my call within an hour, met me 3 hrs later at my home and gave me a written estimate, which included observations of 4 code violations from the other guy, then showed up with a 5 man crew the next day. He and his crew tore out the other contractor's shoddy plumbing, salvaged almost 100% of the copper material to save me money, re-installed the copper pipe plumb and level with correct strapping and routing (the piping is so secure, you can do pull-ups off of it!), installed an external pump from a new washing machine sink in the basement to my existing sewer, installed the pedestal sink and toilet, AND tore out and re-installed new tile because the first contractor installed my new tile incorrectly - all in 9 hrs! They even put the 1/2 bath baseboard back up for me with their nail gun free of charge. Did I mention that Bill Dempsters brother Val is a floor installation expert? I had showed Bill my badly installed tile floor the day before and he brought his brother along just in case I wanted that work done. It was a good thing, because that tile floor job from the other guy looked horrible! All of this work was done for a fair price, which I know because I had gotten quotes for this kind of thing at the start of this 1/2 bath install 7 weeks prior.

Bill Dempster and his crew are BAD ASS. The reviews do not lie. Bill is the real deal. The work he did for my home looks absolutely ""Cherry"" and is of the highest quality. If you need any plumbing work done for a fair price in a timely and professional manner, call Bill now. I guarantee you won't regret it. My lesson learned - Hire licensed contractors and find one like Bill that has great reviews.

Bill is top-notch!
We had him do some gas line work and re-pipe a portion of the house that still had old galvanized supply lines. Bill and his crew did a high-quality job, fully explained what the problems were and what was going to be done to fix it. The fee was fair and the work was done quickly.

Without a doubt, I'm calling Bill the next time I need plumbing work done!
