Demarest is a small, heavily wooded borough in the Northern Valley with large lots, mature trees and a housing stock that ranges from mid-century homes to substantial newer builds. The tree cover is beautiful and hard on underground piping, so sewer line problems and outdoor water service issues come up more here than in towns with newer infrastructure.

We offer same-day service, on-time arrival and upfront No Worries Pricing on every job, and we handle residential and commercial work.
What We See in Demarest Homes & Buildings

Demarest Plumbing & HVAC FAQs
Can a sewer line be replaced without tearing up the yard?
Often yes. Trenchless pipe repair lets us rehabilitate or replace a lateral with far less excavation, which matters on wooded lots with mature landscaping.
How do you find out what is wrong with a buried line?
We run a camera through it. A sewer video inspection shows the pipe material, the location of any break or root mass, and the depth, so the repair plan is based on facts rather than guesses.
It takes forever to get hot water at the far bathroom. Any fix?
A recirculation pump or a point-of-use approach can cut that wait substantially. Which one makes sense depends on the piping layout and where the water heater sits.
