"Rafael and his crew were amazing to work with. The initial visiting for a quote was free and very informative. He was quick to understand my sketches for a totally different deck design, asked really helpful questions, and gave clear recommendations. They were able to start promptly. All of the crew members were very professional in their communication and planning and updates. They were highly skilled and did excellent quality work. I am so happy with my new deck! When work was done, they honored their quoted price. For my project they did not ask for any payment upfront, just payment in full upon completion to my satisfaction. They do take other payment methods but prefer cash so I suggest you ask about your payment options upfront. For the whole process, this company was great to work with. The craftsman of the finished work was excellent quality. I recommend them to everyone."

Family owned business with over 15 years of experience handling Remodeling - General - Remodeling - Kitchen & Bathroom - Room Additions- concrete, framing, land clearing, etc.

"Manny and his team were competent, conscientious, and at all times professional and friendly. We described the shower transformation we wanted, the floor tile pattern, and the backsplash change, and they delivered precisely what we asked for. For a relatively small up-charge they even hung the custom shower doors we purchased, which saved us considerable money. I can easily recommend NW Highland."

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.
