FAQ

Water Heater Installation & Repair — FAQ

How long does a water heater installation take?

Most standard tank replacements are completed in 2-4 hours. Tankless conversions and gas line upgrades can take longer — we'll give you a firm time estimate before we start.

Do I need an expansion tank?

If your home has a check valve or pressure regulator on the main line, most plumbing codes require a thermal expansion tank on a closed water system. We test for this on every job and install one when needed.

Tank or tankless — which is right for me?

It depends on your household's hot water demand, available space, and fuel type. We'll walk you through the trade-offs in plain language and recommend the option that fits your home and budget.
