Water Heater Repair & Installation

No hot water is never convenient. We repair most tank and tankless units same-day, and when replacement makes more sense, we size the new unit to your household — not to whatever was there before.

How it works

Our process

1

Diagnose or assess

We test the unit and tell you honestly whether a repair is worth it or replacement makes more financial sense.

2

Flat-rate quote

Repair price or replacement options — tank vs. tankless, sizing — laid out before you decide.

3

Same-day work

Most repairs and standard tank swaps are completed the same visit.

4

Test & explain

We run hot water at full flow before we leave and walk you through the warranty paperwork.

Pricing

Diagnostic is a flat fee, waived when you approve the repair. Standard 40–50 gallon tank replacements typically run $1,400–$2,600 installed; tankless conversions run higher due to gas line and venting work — always quoted before we start.
