Tankless Installation FAQs

Installing a tankless water heater usually takes 4 to 8 hours, depending on the job's complexity and any needed changes to gas lines or venting. We aim to finish most installations in one day to minimize disruption to your home.

Key benefits include unlimited hot water, lower energy bills, space savings, longer lifespan, and less risk of water damage. They also increase home value and are often more eco-friendly than traditional tanks.

Tankless water heaters need less maintenance than traditional tanks, but yearly servicing helps them work best. This usually involves cleaning out mineral buildup and checking the burner and venting. We offer maintenance plans to keep your system running well for years.

Cost depends on the unit size, whether it's gas or electric, and any gas line or venting changes needed. We give a free, upfront estimate after a site evaluation, so there are no surprises.

Tankless systems offer continuous hot water and typically lower energy use, though they cost more upfront than a traditional tank. We'll help you weigh the tradeoffs based on your household's hot water needs and budget.

Our hot water heater was leaking. They came the same day to do a quote and then installed a new water heater the SAME DAY. Did an excellent job.

Called them about plumbing leaks under the sink. They were responsive, came out next day for a free quote, and got to work. Informative, personable, and the work is superb. Others were shocked at how good the price was.

My husband had a fall and needed a new grab bar for his shower. Todd came within a few days and put a new grab bar in, and I am so grateful for the quick, caring service.
