Overview
Water Heater Installation & Replacement in Longmont
When it is time for a new water heater in your Longmont home, the install matters as much as the unit. Mayer Plumbing sizes, supplies, and installs standard tank, high-efficiency, and tankless water heaters—hauling away your old unit and leaving everything clean and code-compliant.
We help you choose the right system for your household size, hot-water demand, and fuel type, then handle the full installation: proper venting, gas or electrical connections, expansion tanks, drain pans, and permitting where required. Every Longmont water heater installation is backed by manufacturer warranties and our own workmanship guarantee.
Already dealing with a unit that keeps breaking down? Start with our Longmont water heater repair service and we will tell you honestly whether a fix or a full replacement is the better value.
Mayer Plumbing is based just up the road in Berthoud and has served Longmont homes for years—from historic Old Town bungalows to newer builds in Prospect and out toward Hover Acres. That local knowledge is why water heater installation from a trusted neighbor beats calling a big out-of-town outfit that does not know Longmont plumbing.

FAQ
Frequently Asked Questions
Answers to the most common questions from Longmont homeowners.
A standard tank swap is usually completed in 2–3 hours. Tankless conversions take longer because they may require new gas lines, venting, or electrical upgrades, but most are finished in a single day.
For many homes, yes. Tankless units deliver endless hot water, take up far less space, and last longer than tank models—often 20 years or more. We will assess your usage and home setup and tell you honestly whether the upgrade makes sense for you.
It depends on how many people are in your home and your peak hot-water demand. As a rough guide, a 40-gallon tank suits 1–3 people and a 50-gallon suits 3–5, but flow rate matters more for tankless. We size every install to your specific household.
