Replacing aging driveways and walls in Florham Park
Florham Park is a long-established community, and in older neighborhoods the driveways, retaining walls, and drainage that went in decades ago are wearing out. A big part of what we do here is tearing out cracked, failing work and rebuilding it to last, often on tight lots where access takes real care.
We also do a fair amount of site work where older properties are being rebuilt or expanded. That is a big part of what we do here, but it is far from the only thing. We still handle sewer and water lines, septic, grading, driveways, and emergency digs across town.

What tends to be in the ground in Florham Park
Florham Park has no one dominant building era. Its 4,914 housing units are spread across the decades, with the 2010s the largest single share at 19%.
Roughly 37% dates to the 1940s through early 1970s. That is the Orangeburg window, and pipe from it is past the age where it can be counted on.
With 31% built since 2000, a good part of Florham Park is newer, and there the work is usually drainage and grading rather than pipe.
Housing-age figures: US Census American Community Survey 2019–2023 5-year estimates, table B25034. Pipe service lives are documented industry figures. What is actually under any one property varies, so we confirm it on site before we quote a replacement.
Florham Park is split between public water and private wells
About 91.3% of Florham Park’s land area sits inside a public water purveyor’s delivery area, shared between 3 different systems. The largest is Florham Park WD, then NJ American Water - Short Hills. Outside those pockets most properties are on a well, sometimes their own and sometimes one shared with neighbors, and the three situations are different jobs with different rules. Which one you are in is the first thing to settle, and your bill settles it faster than any map.

NJDEP maps actual delivery areas for public community systems, meaning fifteen or more year-round connections; smaller shared and association systems are real but do not appear. Percentages are share of land area, not share of homes, and a state file can lag a change of ownership. The name on your bill beats any map, including this one.
The part that changes the job here
the Borough of Florham Park, which owns both the water and the sewer
Florham Park publishes more about its own infrastructure than almost any town we cover, and it is worth reading before you dig here. Four wells on the Buried Valley Aquifer, two tanks holding 1,250,000 gallons between them, about 48 miles of distribution main, 485 hydrants, 1,250 valves and seven interconnections with other purveyors, serving 3,470 meter accounts across 7.6 square miles. The sewer side is the borough's too: one plant at 1.4 million gallons a day design flow, seven pumping stations, thirty miles of collection pipe, discharging to the Passaic. One caution though: owning a system is not the same as being the only one in town. Roughly two thirds of the borough sits in the municipal delivery area and about another quarter is New Jersey American Water, so the name on the bill still decides who you call.
Most of Florham Park is inside a sewer service area
About 76.5% of Florham Park’s land area falls inside a mapped sewer service area. The largest share goes to Florham Park Sewer Utility STP, with 2 smaller works alongside it. A service area is where sewer is planned and permitted, not a promise that a main runs past your house, so the only way to settle it for one address is to look. Outside it, septic.
Sewer connections, laterals and septic work are all things we do, and which one you need is usually settled in one phone call. Sewer and water line work.
