Overview

Tank & Tankless Water Heaters Done Right

A properly sized, professionally connected water heater is the difference between reliable hot water and constant service calls. We install and repair both traditional tank units and high-efficiency tankless systems.

Every installation includes new braided stainless steel supply connectors, code-compliant expansion tanks and shutoff valves, and a full leak test at the manifold before we consider the job complete — exactly the setup pictured here.

Running out of hot water fast, hearing popping or rumbling from your tank, or seeing rust-colored water? Those are all signs it's time for a replacement, and we offer same-day swaps for most standard tank units.

FAQs

Water Heater FAQs

Tank or tankless — which is right for me?
Tankless units offer endless hot water and lower standby energy use but cost more upfront; tank units are more affordable to install. We'll walk you through both based on your household size and budget.
How long does a water heater last?
Most tank water heaters last 8–12 years. If yours is past that age, is leaking, or is rusting at the fittings, replacement is usually more cost-effective than repair.
Do you install gas and electric units?
Yes, we install and service both gas and electric tank and tankless water heaters.
Can you replace my water heater the same day I call?
In most cases, yes — we carry common tank sizes on our trucks for same-day replacement.
