K2 is proud to have received Angie’s List Top Honors for 14 years running. We design & build custom bathrooms, custom kitchens and outdoor entertainment spaces. We are now well into our second decade in business and have always carefully crafted beautiful spaces - and relationships - with people just like you. Are you ready to do something amazing with your home? Our innovative approach to design, material sourcing, and on-site construction helps you save money, gets projects finished quickly and leaves a mountain of value behind.
"We've had the pleasure of working with K2 twice now. They helped us with a kitchen remodel on our starter home years ago, designing an incredible kitchen in our tiny postage-stamp available space. When we moved again years later into a dated kitchen direly in need of upgrades, of course we called K2! Both times we worked with Teresa on a design and floorplan that made the best sense for how we utilized the space, and she brought practical ideas that worked with our budget and our wish-list. When the project came around, the contractors were all helpful and friendly. The project managers were always a quick call away if anything ever came up. Some project highlights include: - A giant picture window to bring as much light into a previously-dark kitchen as possible, - A half-wall to create a more open space, - Cabinet improvements to create more storage, - Lighting improvements (gross, outdated hospital-like fluorescents to sharp new LED fixtures), - Electric range to gas-range updates, with a hanging hood, - Flooring (hardwood refinishing and tile.) Kitchen models can be such a headache especially with a house full of kids and dogs, but working with K2 helped things go as smoothly as possible."

"Let’s just say communication was stellar from the get-go! We met with Tom to go over what work we wanted to do and there’s just something about making a personal connection with someone that makes you feel confident that the work they’re going to do for you is going to be great, and it was! Can’t say enough about Tom and his brother Jesse‘s professionalism, knowledge and skill!! Along with countertops, we were also installing some unfinished cabinets and we didn’t even know it was an option, but Tom offered without us asking to prime and paint them for us as well, AND he even went and matched the paint so the new cabinets matched the old ones we were keeping, which was great because we were under a time crunch to get this work done before family was coming to stay with us. Tom and Jesse worked with us to make sure everything was completed and that we were 100% satisfied in the short amount of time they had to get it done for us. Everything looks beautiful and we would definitely work with Tom and Jesse again in the future! Actually, hoping to have them come back and do some laminate flooring for us as well! Highly recommend these guys, they are great guys, great communication, 100% trustworthy and I guarantee they will do a great job for you!"

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.
