"We had a great experience working with Don at Seek Design & Renovation on the upgrade of our guest bathroom. The project included installing a vent through the attic, new tiling, a new bathtub, new floor and sanding down our walls to get a more modern look (its an old house with textured walls). All the work was completed in 8 days, everyone in Don's crew was efficient and pleasant to work with. I would definitely work with this company again and I highly recommend them!"

We are a kitchens and bathrooms company. We specialize in custom showers, custom cabinets and counter tops. We staff high end professionals and use sub contractors only when necessary. We also give a very detailed estimate, action oriented so you only pay for the work preformed and gives control to the homeowner.

"These guys were fantastic. They are one of the few companies out there that that actually do what they say will do. They send you daily emails around 830 am describing the activities for the day and who will be inside your house. Their communication is great - they always answer emails and texts in a very timely matter. The master bathroom we had remodeled looks great and was done in the time period they indicated at the beginning of the process. Sure, you could probably find someone cheaper and does inferior work, however we wanted it done right the first time. Nic and Sarah and the entire team exceeded our expectations!"

"On the recommendation of our realtor, we hired OnCall Home Services to remodel the kitchen in our new house. In our previous house, we were burned by a different contractor, so we were a bit nervous entering into this project. Turns out we had nothing to worry about! Beau and his crew were great to work with from the beginning of the project to the end. Whenever we had a question or concern, Beau was prompt to reply or came by the house to discuss. There were no hidden surprises in the costs because Beau was always transparent and kept us apprised about any issues or needed adjustments that came up. He and his crew were courteous, professional, and showed up on time, every day. The project was completed on schedule and we're extremely happy with the results.

FAQs for tankless water heater installation projects in League City, TX

Yes, although they have a higher upfront cost compared to traditional units, tankless water heaters can be worth the investment for many homeowners. They heat water on demand, eliminating standby energy losses and leading to 24% to 34% greater energy efficiency for homes using up to 41 gallons of hot water daily. Tankless units last longer—around 20 years with proper maintenance—and require less space than traditional units. They also reduce the risk of leaks and water damage since there's no tank to corrode and fail.

Tankless water heaters, including gas-powered models, do require electricity to operate components like the ignition and control systems. This means they won't function during a power outage. If you live in an area prone to outages and want to ensure a continuous hot water supply, consider installing a battery backup system or generator to keep your tankless water heater running when the power goes out.

You should set your tankless water heater to 120 degrees Fahrenheit for optimal safety and efficiency, as recommended by the U.S. Consumer Product Safety Commission. Setting the temperature at 120 degrees prevents scalding accidents, particularly for children and the elderly, and reduces energy consumption. Temperatures above 140 degrees increase the risk of burns and promote mineral buildup, which can decrease the system's efficiency.

A 20-minute shower uses 50 to 60 gallons of water, assuming a flow rate of 2.5 to 3 gallons per minute. A typical whole-house tankless water heater can produce 4 to 8 gallons of hot water per minute, providing continuous hot water for long showers. By installing low-flow showerheads and reducing shower time, you decrease water consumption and energy costs, maximizing the efficiency of your tankless system.

With proper maintenance, a tankless water heater lasts around 20 years, significantly longer than conventional tank water heaters, which last between 8 and 12 years. Regular inspections and timely repairs can further extend its lifespan. To keep your tankless system operating efficiently, have it inspected or serviced annually and address any minor issues promptly by contacting a local tankless water heater repair service.
