We Provide Water Heater Repair, Replacement & Installation

Yes. Water heater problems rarely happen at a convenient time, so we staff for emergencies from 5 AM to 11 PM, seven days a week — evenings and weekends included. If you’re dealing with a leaking tank, a gas smell, or no hot water at all, call us and we’ll get a technician to you as quickly as we can. While you wait, there are a few steps that can help. If water is leaking, turn off the cold water supply valve at the top of the heater. For an electric unit, switch off the breaker; for a gas unit, turn the control knob to “off” or “pilot.” If you smell gas, leave the house right away and call your gas utility, such as Atmos Energy or CPS Energy, or 911 before calling us. Texas weather can add to the urgency, whether it’s a hard freeze stressing fittings or a summer leak in a hot garage. Our offices in Garland, Round Rock, and San Antonio help us reach homes across DFW, Central Texas, and the San Antonio area. Every emergency visit starts with our $125 service call, and we confirm the full price in writing before starting work.

Rainstone serves homeowners and businesses from three offices across Texas. Our Garland office covers much of the eastern Dallas–Fort Worth area, including Garland, Rowlett, Sachse, Mesquite, Richardson, Wylie, and Rockwall. From Round Rock, we serve Central Texas communities such as Georgetown, Pflugerville, Cedar Park, Leander, Hutto, and north Austin. Our San Antonio office reaches neighborhoods across Bexar County and nearby areas, including Stone Oak, Alamo Heights, Helotes, Converse, Schertz, Boerne, and New Braunfels. Having local teams in each region means our technicians know the conditions that affect water heaters in your area. North Texas homes often deal with freeze-related issues in winter, Central Texas has seen rapid growth with many newer builds and tankless installs, and the San Antonio area draws notably hard water from the Edwards Aquifer, which speeds up sediment and scale buildup. If you don’t see your city listed, give us a call. We may still be able to help, and if you’re outside our service area, we’ll let you know right away so you’re not left waiting.

Yes. Rainstone stands behind its work with a workmanship warranty, which covers the labor and installation we perform. This is in addition to the manufacturer’s warranty that comes with new water heaters and replacement parts, which typically covers the tank or major components for a set number of years depending on the brand and model. When we finish a job, we’ll explain what your warranties cover, how long they last, and what to do if something goes wrong. For new installations, we can help register your unit with the manufacturer, since some brands require registration to activate full coverage. Keep your invoice somewhere safe, as it serves as your proof of service. Warranty terms can vary based on the type of work, so a repair may carry different coverage than a full replacement or a new tankless installation. Routine maintenance, like annual flushing, can also help protect manufacturer coverage, since some warranties may be affected by neglect or heavy sediment buildup. If you have questions about a warranty on a unit we installed, just call your nearest Rainstone office.

The cost depends on what’s wrong with the unit, the parts required, and whether it’s a tank or tankless system, gas or electric. A simple fix, like replacing a thermostat, heating element, or thermocouple, generally costs far less than repairing a gas control valve or addressing a leak. Tankless repairs and descaling are priced differently again, based on the model and the condition of the heat exchanger. Rather than guessing over the phone, we start with an on-site diagnosis so we can see what’s really happening. Once we know the cause, we’ll give you a clear, upfront quote before any work begins, so there are no surprises on your bill. If a repair would cost close to the price of a new unit, or your water heater is around 10 years old or more, we’ll tell you honestly and walk you through replacement options too. Many Texas homeowners find that age, hard water, and sediment play a big role in whether repair or replacement makes more sense. Either way, the decision is yours, and there’s no pressure to commit.

Yes. In Texas, water heater installation and repair is regulated by the Texas State Board of Plumbing Examiners (TSBPE), and the work must be done by or under the supervision of a licensed plumber. Rainstone’s technicians hold TSBPE plumbing licenses, and you’re welcome to ask for a license number when we arrive or verify it on the TSBPE website. We also carry liability insurance, which protects your home and property while we’re working. Hiring an unlicensed or uninsured handyman to replace a water heater can lead to code violations, failed inspections, voided manufacturer warranties, and safety risks, particularly with gas lines and venting. Cities like Garland, Round Rock, and San Antonio generally require a permit for water heater replacement, and we can take care of the permitting process for you. Rainstone is also accredited by the Better Business Bureau, which reflects our commitment to transparent pricing, clear communication, and resolving customer concerns. Choosing a licensed, insured, and accredited company gives you confidence that the job is done safely, to code, and with accountability if you need support afterward.
