Randolph is a hilly, wooded township of larger lots and winding roads, with Route 10 and the Sussex Turnpike carrying most of the traffic. Much of the housing went up between the 1960s and the 1990s as colonials, splits and contemporaries set into slopes, often with walkout basements and long driveways. Sloped sites and mixed utility service make this one of the more varied towns in the county to work in.

What We See in Randolph Homes & Buildings
- Some parts of the township are on private wells and septic systems rather than public utilities, which brings pressure tanks, well pumps and hardness treatment into play.
- Houses built into hillsides with walkout basements and multiple levels frequently suffer uneven heating and cooling from a single-zone system.
- Long driveways and setbacks mean water service and sewer lines can run a long way from the street, so leaks get located with equipment before anyone digs.
- Contemporary designs with cathedral ceilings and large glass areas need capacity calculated on the real heat gain rather than square footage alone.
Sections of Randolph we serve include Shongum, Mount Freedom, Center Grove, along with every other part of the township.

Randolph Plumbing & HVAC FAQs
The top floor of our hillside house is always warmer than the walkout level. Can that be evened out?
Yes, and it rarely takes new equipment. Multi-level houses here usually need a return-air or duct correction, zoning, or a mini split on the level that loses the fight. We measure airflow at each level before recommending anything.
How do we know whether we are on a well or on public water?
Look for a pressure tank and a well pump control in the basement or utility room instead of a water meter. If you are unsure, we identify it on the first visit and explain what it means for your water heater, fixtures and any treatment.
Do vaulted ceilings and big windows change how you size a system?
They do. Glass area, ceiling height and orientation drive the load, so we run a heat loss and heat gain calculation instead of sizing from square footage. Oversized equipment short cycles and leaves rooms humid.
