"I love my new shower surround from Bath Planet of Arkansas! Chris was very helpful from the beginning through the end of the installation. I went into the showroom with only a vague idea of what I wanted. Chris helped me figure out a beautiful fit for my bathroom. When the installers came to my house they were kind and very respectful of my home. They covered up all the floor surfaces where they walked in and out of my home.

"This was amazing! I had no idea this service existed. After searching and contacting various repair places for my washer, this was the most cost effective option. I figured if it didn't work, my machine is old and I would be out $40, not the $100+ to have a tech come out and just diagnose the problem. I am pretty handy and my washer is old anyway, so if it is broken, I have to get a new one anyway. My tech, Steve, was great! He predicted what was wrong after listening to the machine, calmly walked me through dismantling the machine and when we got down to the motor, he was right! He sent me a link to the part I would need, and let me know to contact them again if I needed help installing it. My machine works even better than before it broke, its beautifully quiet and efficient. I will definitely be saving this company for any future repairs on appliances I may need. The service was $40 + the part cost, which was about $8."

Established in 1933, Olshan Foundation provides cost-effective foundation solutions to residential and commercial property owners. Services are backed by an available lifetime warranty, friendly customer support and convenient financing options. Free, no-obligation structural assessments are performed by Certified Structural Technicians. Since no two homes are alike, our Technicians carefully inspect the problems affecting your home before developing a comprehensive repair plan designed uniquely to your property. Olshan is the exclusive provider of the Cable Lock ST Plus repair system. This hybrid design combines the penetrating power of concrete with the long-term durability of steel, providing a longer, deeper more secure repair. We also offer drainage and root barriers to help prevent foundation damage. Schedule a free, no-obligation assessment now. Your home’s structural integrity depends on the strength of your foundation. It supports everything else – walls, windows, floors, doorways, roof – so when your foundation is damaged, it can cause serious problems throughout your home. Like most things in life, your foundation is subject to environmental stress. Expanding and contracting soil, excessive moisture and inadequate drainage are some of the most common threats to your home’s foundation. Over time, environmental stressors can cause a foundation to shift, crack or settle unevenly. And homeowners often miss early warning signs of foundation damage. Homeowners spend about $4 billion annually stabilizing faulty foundations, and those costs may increase as more homes are built in areas known for shifting soil. Understanding risk factors and signs of foundation problems can help you protect your most valuable asset from irreversible damage.

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.
