Arizola Plumbing & Home Services is a small local business located in Fredericksburg Tx. Founded in 2020 by Fredericksburg local, Ricky Arizola. We started as a very small plumbing company and have successfully grown into a fully capable home services company. We offer same day, next day services and free estimates.

"I have had an appointment that was scheduled for nearly a month. I had to close my business to have this job done. I called a couple hours before the show up time and they said that someone should have called to let me know the person that was going to do the job quit. No one had ever called to let me know. Then they said they would send someone to do it but no one came and that was scheduled for two hours ago. I have lost business today and the job was not done. I am very disappointed. They do not answer phone calls. The only text I got was that they were sorry that no one told me they were not going to come."

"Expo Home did a fantastic job from beginning to end. Maurice our sales representative came to our home and very thoughtfully walked us through everything. He helped us to make a difficult and expensive purchase decision. The contract was signed Friday evening and the work was completed by Thursday afternoon. The installers Ricardo and Omar arrived promptly on install day morning at 8am and worked quickly to do all the work by 4pm. They respected our home and kept work areas clean with tarps. Omar especially kept me informed of the progress of the project throughout the day. Ricardo as the lead installer was very skilled in performing the work and knowledgeable about all the details of the project. I would highly recommend Expo Home for your next tub to walk in shower conversion. Thanks to everyone at Expo Home team and satisfied to be member of their family."

Genie Bath Systems provides homeowners with custom bath remodeling solutions, to include a full-line accessibility needs. All of our products are custom made in the USA. Factory Certified Installation.Lifetime Warranty.100% Financing . PLEASE NOTE: WE DON"T PERFORM KITCHEN REMODELS

"Last October, my sister, an elderly veteran living alone, contracted Genie Bath Systems to remodel her master and guest baths. She was diagnosed cancer and passed before the remodel was complete. Which, to be fair as we were not able to work with Genie while attending to my sister. The contract was expensive. Very expensive. The cost of the remodel is close to 1/4th the value of her home. I noticed there were issues with the remodel that showed a surprising lack of attention to detail. Genie sent people to address the issues twice. Yet issues remain. My calls to my contact at Genie are now being ignored. Also, the only document I have for the remodel is the contract my sister signed. It is not detailed. I have and continue to ask for a breakdown of the cost. An estimate or work order. This request is also being ignored. I am disappointed and have to wonder why Genie will not provide this information. I have several other questions for Genie that I will not go into here. But based on my experience, I cannot recommend Genie. In fact I would warn anyone considering Genie to be very careful about the cost of the contract."

Tankless water heater installations FAQs

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
