Oil tank replacement across New Hampshire.

THE WALSHCO DOUBLE-WALL PACKAGE
$3,600installed package
Roth or Granby 2-in-1
A double-wall tank, installation, permit coordination, old-tank removal and cleanup, with oil transfer and reconnection where conditions allow. Your written estimate confirms the manufacturer, model, capacity and complete scope.
Access, piping, relocation, fuel handling and additional work can affect the final price. We review the details with you before booking.
Read the full package informationYOUR PROPERTY. A CLEAR PLAN.
A tank replacement planned for your property.
A replacement starts with the whole setup: the existing tank, where the new one will sit, the piping and the route through the property. Photos help us review these details before confirming equipment or a price. Let us know whether the tank is in a basement, garage or outdoor location.
Room for the tank—and a route to it.
The available floor space is only part of the picture. Doorways, bulkhead stairs, ceiling height and tight turns can affect which tank fits and how the work is planned. If you know the current tank’s capacity or model, include it. Photos of the label and the surrounding space are useful too.
Considering a different location or a larger tank? Tell us at the start. Changes to the fill, vent or oil line can affect the installation scope. Steel tanks and double-wall options can be discussed alongside the space and access you have.
Statewide work, with the visit planned ahead.
We travel throughout New Hampshire. Include any driveway, parking or access constraints and your preferred timing when you request an estimate. For an outdoor tank, show its position and the surrounding area. We confirm the work arrangements and installation date with you after reviewing the project.
Local permit arrangements checked.
Permit and inspection arrangements are confirmed for the town where the work takes place. WalshCo coordinates the required steps within the agreed scope. For example, Keene’s fire prevention information lists tank installation and removal permits. We check the requirements for your property rather than assume every New Hampshire town uses the same process.
BEFORE YOU BOOK
New Hampshire tank questions.
Do you travel beyond Cheshire County?
Yes. We serve all of New Hampshire, including the Monadnock region, Merrimack Valley, Seacoast, Lakes Region and northern New Hampshire. Send your town so we can discuss the project and scheduling.
Can you remove the old tank and transfer the oil?
Yes, with the removal and oil-handling arrangements confirmed in your estimate. Tell us how many tanks you have and approximately how much oil remains. Transfer depends on the fuel and site conditions.
Can I change tank capacity or location?
Ask us to include that in the review. Available room, the route into the property and changes to piping all matter. We confirm the tank model and any relocation work before you book.
