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."

"Our experience is identical to what other reviewers shared. And yes, you should run from this company as fast as you can. Do not buy what Abraham shared that the payment must be made when the inspection is passed. Check the Business and Professions code yourself, the payment only needs to be made when the job is completed. It is very COMMON that the job is not even done or poorly performed even the inspection is passed. Here are the issues that multiple families including us run into with this company:: The project was delayed for over 9 months. No one manages the job. He often employs young men from his own Jewish community. They are enthusiastic but had no prior experience. The worse part is that they don't get paid. Two of them even set up a new construction business knowing Abraham will never pay them. Subcontractors can put your house on lien also. Many reviews you see on Yelp, Google, Angi are NOT genuine. Even the references are fake with hindsight, we were given 2 references. One reference shared the exact same accent as the PM. The other reference was initially happy with their work, but then reached out to us and shared a similar horror story with them like what we experienced. You will lose a lot of $$$ on materials as the subcontractors will somehow leave a thousand dollars worth of quartz at home. Maybe they want to compensate for the money Abraham owed them? Let me tell you, reordering materials is not fun."

We have 7 year experience on plumbing we are very clean and we use heavy duty materials. To get the best quality project.

"Fernando was very responsive - he returned my request very fast with a confirmed time to come to my house to repair ... both cold water and hot water under the kitchen sink were leaking. He showed up at my house at the exact time he said, and replaced both valves to stop the leakage. Excellent quality of work and professionalism. We hired him again second time to 1) install a new water heater tank and a new kitchen sink faucet, and 2) a full house plumbing inspection to ensure if any unseen leakage or issues ... we are very satisfied with his services."

FAQs for plumbing installation for a remodel or addition projects in San-gregorio, CA

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
