Septic system replacement in New Boston, NH

When a septic tank, a leach field, or the whole system has failed, C.J. Burke Enterprises can replace it. We are a New Boston company, and Carson Burke is a New Hampshire licensed septic installer (NHDES permit #5889). Replacement is common in this area. Many homes are on older systems, and most of the towns we serve have no municipal sewer, or sewer only in part of town.

Call or text 603-303-1543 if you already know the system has to come out, or if you are still trying to figure out how bad the problem is.

When replacement is the right path

Some problems can be repaired. Others cannot. Replacement is usually in front of you when:

  • The leach field is failed — for example, effluent is surfacing, or the field will no longer take the flow
  • The tank is deteriorated, collapsed, or no longer structurally sound
  • The system is undersized for the house as it is used today
  • A buyer, a lender, or the town has required a new system before a sale or a building change
  • A previous installation was not finished correctly and has to be taken back out and reset

We will look at what you have and be direct about whether a repair is realistic. If the system has to be replaced, the new work still has to follow a current, NHDES-approved design. An old system cannot simply be “put back the way it was” if the rules, the soils, or the house have changed.

What the work looks like

Replacement often means removing the failed components, hauling unusable material off the site, and installing a new tank, a new leach field, or both, on the approved plan. On some lots the new field can go in the same general area. On others, the design has to find a different location because of soils, setbacks, wells, or wetlands.

Access matters as much on a replacement as it does on a new install, and sometimes more, because the house, the driveway, and the landscaping are already there. We have taken out old fields on tight lots where material had to be moved in stages and hauled on a smaller truck, then brought the new material back in the same way. The equipment should fit the site, not the other way around.

We also see jobs where a previous contractor left the work unfinished or set a tank at the wrong elevation. That kind of correction is still a replacement job: the tank has to come out, the excavation has to be made right, and the connections between the house, the tank, and the field have to be completed as they should have been in the first place.

Permits for a replacement

A replacement system needs a permitted designer and NHDES approval, just as a new system does. If you already have a designer or a set of approved plans, we can start from those. If you do not, we can help you understand the sequence before anyone puts a machine in the ground.

Please do not have an unpermitted installer “just swap the tank” or bury a problem. That tends to cost more later, and it can complicate a sale or an inspection.

Towns we work in

New Boston, Milford, Amherst, Wilton, Brookline, Mason, Hollis, Merrimack, Bedford, Mont Vernon, Goffstown, Weare, Francestown, Dunbarton, and Lyndeborough.

In Milford, Wilton, Merrimack, and Bedford, sewer covers only part of the town. If your address is outside those areas, you are likely on a septic system, and replacement is often the only option when that system fails.
