"So far so good. Snaking of kitchen sink with very old pipes. Hopefully snake did not poke pipes. Only time will tell. Keeping fingers crossed. They did a good job explaining and triple checked for leaks before they left. Of course they tried to upsell and gave us a metal trap they did not quote us upfront for. We would have chosen it over plastic, but price difference would need to be cleared upfront. That's the only negative. Otherwise, thus far we are very happy with the result. Thank you for coming on such short notice and on time! Super appreciated. 4.5-5 stars."

We started Better Water Heaters to provide fair pricing and quality service to the customers seeking water heater service or replacement. The truth is, most companies overcharge because they know you need hot water immediately and will probably pay a lot to get it quick. My typical customer is one who has price shopped the competition and have decided most companies either charge way too much or are hard to pin down to a firm price. We understand. You simply need a water heater and don’t want to deal with a sleazy salesman…you want to talk to a plumber….so give us a call and we’ll talk. At Better Water Heaters we do something quite rare in the plumbing business- install water heaters for a fair price. We grow our business one satisfied customer at a time; we don’t take advantage of a plumbing emergency and charge unreasonably. Your referral is important to us that is why we always will work to insure your complete satisfaction. We’re a small company and we keep our overhead low, because of this we don’t need to charge unreasonably. Of course we are licensed, bonded and insured and are very experienced at water heater installation and repair. We are experts in convention water heater repair and replacement, Tankless water heater installation, and other plumbing issues. We are the only water heater installation company in northern California that has earned the prestigious DIAMOND CERTIFICATION. We are also member of the Better Business Bureau. Our advertised prices include a quality water heater, basic installation and disposal of your old unit; Extra parts and labor required to do the job right, are additional. Call us for all your water heating needs. Estimates are always free and we never charge extra for nights, weekends, or holidays.
"Better Water Heater installed our tankless water heater incorrectly, creating a significant safety hazard for our tenant, an African American family of 5 with 3 small children. After a contractor from AHS reviewed the installation, they confirmed multiple issues, including code violations and fire risks. Major Problems with the Installation: Unsafe placement in a closet - The condensate has no proper drainage, which could lead to mold, rust, and fire hazards. Improper use of an evaporator pan - This pan is not intended for water heaters, creating a fire risk in an enclosed space. Oversized unit for our home - The Rinnai RU160iN is designed for larger homes. It's far too big for our 1-bed, 1-bath house, making it inefficient. Insufficient gas line - According to AHS, the gas line is too small to support this oversized unit, which could lead to gas flow issues or even pose a fire hazard. The city won't allow this installation to pass inspection because the gas line doesn't meet the required capacity. Permit/code violations - The installation was done without a permit and violates multiple building codes. When we confronted the company, they insisted their work was done correctly. Their "solution"? If we wanted the job to be done legally, we would have to pay for both the permit, their time working with inspectors, and additional costs to fix their mistakes--$995 for a bigger gas line to support the oversized unit. On top of that, they quoted us $585 for permit costs, even though the city building department told us the permit fee is only $150. Bottom Line: If you want a safe, legal, and code-compliant installation, DO NOT trust Better Water Heater. They cut corners, refuse accountability, and expect customers to pay extra to fix their mistakes."

TJ's Plumbing has been in business for over 10 years we specialize in residential and commercial Plumbing systems. We pride ourselves on the quality work we provide, while delivering great customer service! Call -or- click to schedule your estimate today!
"Though I am happy with the final result, I feel that TJ did a bit of a bait and switch. The person who showed up, Felipe, was from a different company. "TJ" quoted me $900 for the job and $300 to move washer and dryer to access the main valves. That's $1,200. In the end, washer and dryer were not moved. But I did ask them to replace a faucet cartridge in my bathtub, which they did. But before that, Felipe had managed to turn off the water to my unit without moving washer and dryer. He then had to cut into drywall to locate the outbound pipes, but made a mistake. The next cut he made found the water pipes but these were the wrong pipes. An emergency water shutoff to the building was required. In the end, the bill was for $1,800. They did not take credit card. No receipt was given to itemize work done. These guys, from Moor Plumbing Solutions, did work hard and got the job done but there was a serious lack of transparency from the very beginning, not to mention a near disaster."

FAQs for water heater service projects in San Mateo, CA
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.
It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.
It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.
