General contractors, exterior siding, roofing, thermal walls and thermal windows. Complete interior remodeling. Kitchens and bathrooms, flooring and painting. Foundation repair and custom patios

"Alex Blaker and his team were referred to me by ADU small home sales person in Austin Tx. My project was creating additional barrier walls in a home for the PadSplit app. We had to add 3 electrical outlets, as well as connect a clothes washer that required all lines electrical and water to be ran. Alex was cordial, easy to work with and genuinely cares about the work and level of craftsmanship that goes into the project. You will meet Dario and others on his team who are incredibly polite, clean, and efficient. Project was completed in a little over a week. Budget: initial bid around $7800 + taxes, two owner approved add ons elevated the project around $600. (Plug relocation, and dryer vent routing) Payment was made in 3 payments over the life of the project. I like this as it lets you see the project be started first. Alex kept me in the loop every day and came over in person to inspect, and recommend updates to the job. Happy to work with Alex and his team and look forward to working with them on future projects!"

"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.

Tankless water heater installations FAQs

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.
