Delaware Township is the quiet stretch of countryside between Flemington and the Delaware River, with the village of Sergeantsville at its center and Green Sergeant's Covered Bridge on the road down toward the Wickecheoke. Much of the housing is old — stone and frame farmhouses with additions, low headroom and mechanical spaces that were never designed for modern equipment. Fitting new systems into buildings like that is a design problem as much as an installation, and we plan it before anyone starts cutting.

What We See in Delaware Township Homes & Buildings
- Stone and timber farmhouses often have shallow crawlspaces and stone-walled cellars, so equipment placement, venting routes and condensate drainage all have to be worked out in advance.
- Homes here are typically on septic, and how a drain problem is cleared matters — we camera the line first rather than pushing a heavy volume of water toward a tank and field of unknown condition.
- Ductwork is simply absent from many of these houses, so ductless heads and compact high-efficiency boilers are the practical route to comfort without tearing out plaster and lath.
Sections of Delaware Township we serve include Sergeantsville, Rosemont, Locktown, along with every other part of the township.

Delaware Township Plumbing & HVAC FAQs
We are on septic. Will clearing a drain cause a problem with the tank?
Not if it is done thoughtfully. We identify what the blockage is first, then choose a method that clears the line without dumping an unnecessary load into the tank, and we will tell you honestly if what you actually need is a septic contractor.
Our old farmhouse has no ducts. How can we add air conditioning?
A ductless system is usually the cleanest answer, with wall or ceiling heads in the rooms that need cooling and a small outdoor unit. Where there is usable attic or closet space we will also price a compact ducted option so you can compare.
Do you cover Sergeantsville and the smaller roads, or only the Flemington area?
The whole township, including the outlying roads. Our trucks are already coming into this part of Hunterdon, so an address off a back road is scheduled the same way any other one is.
