Montgomery covers a wide stretch between the Sourland Mountain and the Princeton line, taking in Belle Mead, Skillman, Blawenburg and Harlingen along Route 206. Lots here are generous, many of them an acre or more, and a good share of the township handles its own water and wastewater rather than relying on public lines. Long buried service runs and private well and septic systems together account for a large share of the work we do in the township.

What We See in Montgomery Homes & Buildings
- Acre-plus lots mean long buried water and gas runs between the street and the house, so a leak can go unnoticed until the meter or the pressure gives it away.
- Much of the township is on private wells and septic, and groundwater hardness here shortens the life of water heaters and fixture valves unless it is treated.
- Larger newer homes often carry two or three separate systems, and getting those zones balanced matters more than installing the biggest equipment that will fit.
Sections of Montgomery we serve include Belle Mead, Skillman, Blawenburg, Harlingen, along with every other part of the township.

Montgomery Plumbing & HVAC FAQs
How do you find a leak in a water line that runs a few hundred feet to the house?
We start by isolating the house from the buried run so we know which side is losing water, then use pressure testing and acoustic listening to narrow the location before anything gets dug up. That usually turns a long trench into a short one.
Should we test and treat our well water before replacing the water heater?
It is the right order to do it in. Knowing the hardness, sediment and iron levels tells us what treatment the house needs, and a new tank installed behind proper treatment simply lasts longer.
Our house has two systems and the temperature is never the same upstairs and down. Can that be balanced?
Yes, and it is usually a commissioning problem rather than an equipment problem. We measure airflow and temperature split on each system, adjust dampers and fan settings, and correct thermostat placement or staging before recommending any new equipment.
