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. read more

Grant Plumbing has a great team that does basic plumbing to top-tier level plumbing (copper re-piping, sewer work, water heaters, etc). We called Scott for help with a fine finish installation and help with some new appliance consulting and installation. The cost was solid, and the work was very clean. Scott and his team are San Mateo / Foster City locals. They are professional, informative and extremely helpful. We will use Grant Plumbing again for a job of any size or requirement. read more

Scott Grant is probably the best and most affordable plumber you're gonna find in the area. He and his guys are top notch and they know what they're doing. I've had the do a number of jobs around our home. He showed up fast and fixed fast and properly. I highly recommend this company and have told my neighbors about him when a conversation of plumbing comes up. read more

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. read more

I'd give these guys zero stars if Yelp allowed. My tankless water heater stopped heating water, so I called Grant and Scott (the owner) spoke with me on the phone. He claimed that they were knowledgeable about these and could find the problem. Scott himself did NOT come to the job, instead he sent someone else. This guy clearly knew little to nothing about water heaters in general. He opened the unit looked around, pulled a tube and pretended he knew anything at all. After 15 minutes he got on the phone with Scott and spend a good 20 minutes or so on and off on the phone. Then he told me that the problem was the COMPUTER, but that I was better off fixing it. I asked for quotes and he "called his supplier" (later he contradicted himself and said he called Scott) and said they would get back to him shortly. Then he said: "Well you have me hear for another 20 minutes as you pay for the hour, so let me poke around more". 20 minutes precisely later, he asked me to pay the $120 of his "inspection visit" and promised me that I'd have a quote for fixing the unit as well as installing a new one within the day. It's been two days and I'm yet to hear back. I had a second plumber come by and within 15 minutes, he'd diagnosed the problem, showed it to me and the unit is working right now! Bottom line is, Grant just wants to collect money from plumbing visits as Scott and his team really don't have a clue of what they are doing (they can probably do easy things like unclog toilets). tl; dl; Grant plumbing is going to try to cash money from you for no work, don't call them! read more

As a property manager I'm always looking for a great plumber. Scott Grant is now my go to plumber for all my properties. He's extremely knowledgeable, responsible and tries to save you money wherever he can. He does a very thorough job and makes sure the plumbing issue is completely resolved instead of just doing a quick fix that may not resolve the problem. Just recently I had him come out to take a look at a leak in an apartment. He was able to quickly isolate the root of the problem, fix the problem and take steps to repair the damage that was already done (including personally calling several sources to get me a great price on renting a large heater to dry out some badly water damaged areas behind the walls). He's a wonderful plumber and has a great easy-going personality which doesn't hurt! read more

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! read more

I didn't think professionals like this existed anymore. I hired Grant Plumbing for 2 jobs. My husband has ALS and I was desperately combing the internet for the right kind of toilet for him. Then I made a few calls and ended up speaking with Grant Plumbing. They helped me find what I needed and did the install. Sometimes there are angels. Then we needed a faucet replaced. Grant Plumbing did the job well and fast. These are not big jobs but they were done cheerfully and quickly. Thank you Scott and Dave! You make a difference! read more

Having just sold a house and bought a new one, I have been dealing with many different service people. Scott stands out a one of the best - great communication (including email), prompt, efficient, knowledgable, personable, honest and practical. He helped me review plumbing items flagged in our home inspection report providing advice on which items were genuine issues worth addressing and which were not. He then took care of the remaining items. He also identified and corrected an improper fitting on our tankless water heater that resulted in greater flow and faster hot water. We will continue to rely on Grant Plumbing for our future needs. read more

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. read more

I am still trying to get Scott to return my calls about the shoddy job he performed on my clogged toilet to the tune of $700.00. Even my contractor called him and got no response. He apparently poked a small hole in the clog and then assumed it was fixed. When that didn't work, he did come back and did the same thing all over again. But this time when he replaced the toilet, he didn't seal it properly and when it backed up yet again the backup came under the hardwood floor and ruined that and the subfloor. This guy is not to be trusted to do dependable work and I am now investigating how in the world I can get my money back! I've had RotoRooter and my contractor inspect his work and both came to the same conclusion. Patty Kovas, Atherton, CA read more

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 read more

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. read more

I Robert Pollock at R J Pollock Concrete Service just did a concrete job for Scott Grant Plumbing and saw his work at 320 Nimitz Ave, Redwood City CA. He is great at what he does and is very responsible . I really would hire Scott Grant for any plumbing job I have. Great Guy !!! read more

I've worked with Scott over the past three years on a variety of home plumbing needs both planned and emergency. He's always been dependable dedicated and a great experience to work with. Almost don't want to leave this review as he's already busy enough, but I feel I owe him for the great service he's provided read more

scott provided very responsive and professional service. i've dealt with several plumbers, and he has been by far the best.

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. read more

I have used Grant Plumbing three times, once at a rental property and twice at my residence. I am more than happy with the results on all three jobs. They were reliable, courteous, did great work and their pricing was competitive. Grant is my go-to for plumbing needs. read more

Scott came out to gives us an estimate. He was very professional, kind, considerate and KNOWLEDGEABLE. We went with Grant Plumbing after 4 previous estimates. Scott ran a 2 inch pipeline from the kitchen and laundry abandoning the the old one. They had to dig a trench to tie to the mainline. We were very satisfied with the end result. I highly recommend Grant Plumbing to anyone!! These guys know their stuff!!! read more

I had a sewer line backup yesterday. Was lucky that Scott had a gap between jobs. he and his partner came within 20 mins. They quickly identified the problem and solved it very quickly and professionally. His price was very reasonable. I am very happy with his service. Will definitely use his service again in the future. read more

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. read more
