I recommend Scott highly. I found him on Yelp (tons of stellar reviews), after having a severe clog affecting the whole house. I left a message and right after that, I also contacted a friend to ask who they used for their recent remodel. By coincidence, they responded Grant Plumbing, and couldn't say enough good things. I told them I had just contacted him.

He had a new $800 snake and it broke in half while he was trying to unclog this pipe issue and he was so chill about it. I felt horrible. He spent a long time trying to get the clog fixed, but in the end, it was so severe, we needed a company with a heavy duty video camera. He recommended the company (Brandt Plumbing).

He felt bad that I also had other issues with the plumbing, due to a recent remodel that hadn't gone that well. He ended up charging me about 1/4 of what he should have, and he broke his new pricey piece of equipment, to boot.

I have used him since and he always responds immediately. Very honest, very good at what he does. Great prices. Nice guy.

Having experienced numerous plumbing issues in my home and my rental homes in the Bay Area for over two decades, I've had the dubious pleasure of interacting with many plumbers in the area. Some can be pretty unscrupulous operators.

My experience with Grant Plumbing however, was very professional and reaffirmed by faith in good honest plumbers. The blockage in my mainline was expertly resolved at a very reasonable cost. Thanks Miguel!

I also got an extremely competitive quote for an outside outlet to circumvent the awkward messy process, due to the plumbing construction of my house, which requires removing my toilet whenever I need to snake out the mainline.

Had an emergency plumbing issue -- didn't want large firm but wanted someone who was local to San Mateo and experienced. Reached Scott directly -- over the phone he was very knowledgeable about the issue and how to fix it. Called a few other places but got either answering services or telesales. Decided to go with Scott -- after showing up, he and his worker were very efficient at fixing the issue and Scott also fixed another minor issue we had in our bathtub. Turns out Scott is a great guy (w family and kids), been in business for 10 years, got his experience working at a big company, does a mix of residential and commercial work and is quite knowledge about everything from plumbing to bathroom/kitchen renovation.

They unclogged outside drainage pipes at our home and did a very good job. They arrive on time and completed the project in a reasonable time with a fair fee. We will use them again if have any plumbing problems. Thanks for your good work!

Well, it was time for a new toilet- turned out the old one had been leaking for quite some time. Could have been a nightmare situation. Scott, Dave and Miguel put in the toilet, a new bathroom floor, and ceiling fan in one day with very little stress on me- a busy working mom..
They were a joy to have in our home!!
Way to go Grant Plumbing!!!

I have been using Scott for several years after being referred to him by my sister-in-law. My prior plumber had retired and I spent many years looking for someone I felt was reliable, high quality, trustworthy and fairly priced. Well I finally found him and his name is Scott Grant and he has done minor and major jobs for me. I never wrote an online review of anyone but latest service by Scott is just too good to go unnoticed. On Friday evening at about 7:00 PM I called Scott because I had a leak under my kitchen sink. Scott knew I was in a bind but unfortunately he was not available on Saturday but he could send someone from 10 to 11. The person arrived about 10:15 and within an hour I had the problem resolved. Scott, thanks again for saving the day. My only regret is that you deserve more than the 5 stars that Yelp lets me give you.

Fantactic Service!!! He will be the only plumber that we ever call again. Scott was so accomodating to us after having such a bad experience with another plumber. He came out right away for us and was able to do the job first thing. Thank you so much for everything

I recently closed escrow on a house in San Mateo that is over 50 yrs old. Usually the plumbing still can be in decent shape, but because this particular house is against a hillside, water from the hill passes under the house. The presence of moisture accelerated the corrosion on the cast iron sewer main in the crawl space. I called a few plumbers. Scott has over 13 years of experience and his estimated price was very competitive, so I hired him to replace my sewer main. My crawlspace is very moist and 18 inches from soil to joists, which makes this job very difficult. Scott and his crew promptly came to the house, finished the job in 2 days, and even located water accumulation by the side of my house that needed attention. Now I have a new sewer main that will hopefully last another 50 years. Overall, I thought Scott was very professional, and he successfully completed the project without any hiccups. I highly recommend Grant Plumbing.

As an update...Scott did text me and showed up the following day to do his estimate and emailed it to me within 24 hours. His pricing is very fair and he also gave me some honest advice. I had mistakenly thought the water heater had to be elevated off the ground 18 inches to be up to code. Another plumber tried to charge extra for this without saying anything, but Scott told me the newer water heaters did not have to be raised off the ground anymore. Will update if we use him.
