Water Heater Replacement in Northeast Texas

When the tank is split, or the unit is old enough that the next part isn’t worth it, replacement is the job. Underwood installs tank and tankless water heaters across Collin, Grayson, Fannin, Hunt, and Lamar counties.

Tank Split? We'll Schedule the Replacement.

Shut the cold supply to the heater if water is running out of it. Call (903) 449-1677 and we’ll get a replacement on the schedule.

Our Water Heater Replacement Process

Call or request a quote: Gas or electric, tank or tankless, and how many showers the house runs at once.

Size it: The old unit’s recovery and the house, not a bigger tank because it was on the shelf.

Explain the install: Where it sits, the vent, the pan, and the shutoff. You approve it before the old one comes out.

Swap it: Most replacements finish in one visit. The units we install most are staged so we aren’t waiting on a warehouse.

Fire it and test: Hot water at a tap, no drip at the fittings, the T&P and the pan drain checked.

Haul the old unit: The failed heater leaves with us. The closet gets dried out.

The Underwood Water Heater Standard

A leak from the tank itself, or a unit old enough that the next part costs more than it’s worth. We’ll put both prices in front of you.

Often, yes, if the gas line and the vent can carry it. We’ll say so on site if the closet can’t take the change.

Homes across Collin, Grayson, Fannin, Hunt, and Lamar counties, from offices in McKinney, Bonham, and Sherman.

A straight tank swap is usually the same day. A tank-to-tankless change can take longer if the vent or the gas line has to move. We’ll tell you before we start.

Yes. Water heater replacements are financed, subject to credit approval. See the Financing page.

I needed a sewer tank cover replaced due to it being hit by the lawnmower. These guy fixed it in less than 30 minutes. Chad also suggested putting landscaping stuff around the 4 tanks to prevent this happening again. Totally happy with their service.
