Hightstown is a small borough completely surrounded by East Windsor, built around Peddie Lake and a compact main street of nineteenth-century frame houses and storefronts. Housing that old usually means radiator heat, original waste piping, and additions that were tied into systems never sized to carry them. The low ground near the lake and Rocky Brook also puts basement water high on the list of things people here ask us about.

What We See in Hightstown Homes & Buildings
- Victorian-era frame houses in the borough commonly still run on a boiler with radiators, and whatever cooling exists was added decades later.
- Low-lying properties near Peddie Lake and Rocky Brook have taken water in major storms, so pump sizing, battery backup and a properly routed discharge are worth discussing before the next one.
- Downtown buildings with apartments over storefronts often share one drain stack and one water service, which changes how a repair has to be scoped and who it affects.

Hightstown Plumbing & HVAC FAQs
We own a building with an apartment over a storefront. Can you work on both?
Yes, and we plan it as one building rather than two jobs. Where a stack or a water service is shared, we tell you up front which units will be affected and for how long.
Why does our hot water run out so quickly in a house with one bathroom?
In older houses it is usually sediment in an aging tank cutting the usable capacity, or a failing dip tube or lower element. We check the tank before recommending anything, because a flush and a part sometimes buys years.
Is Hightstown too far south for you to come out?
Not at all — Mercer County is part of our regular service area even though we are based up in Bergen County. We schedule Mercer visits in batches, so give us a call and we will set a time within 24 hours of booking.
