Originally inhabited by the Lenape Native Americans, Randolph became known in the 18th century for its iron mining and farming, with forges and mills along the Black River powering early industry.
By the 1800s, the town had grown into a resort destination, with hotels and summer camps around Shongum Lake and Millbrook bringing visitors from across New Jersey and New York.
Today, Randolph balances its past with modern development, home to landmarks like Freedom Park, Hedden Park, and the Randolph Museum.
But Randolph’s geography makes basements and foundations especially vulnerable. With an average of 51 inches of rainfall and 33 inches of snow annually, plus sloping terrain and dense clay soil, many homes face water intrusion and shifting foundations year-round.
Historic houses near Ironia and Millbrook often feature older block or stone foundations with minimal drainage, while newer developments in Shongum or Center Grove can still experience water seepage from nor’easters, rapid snowmelt, or saturated ground.
That’s why United Waterproofing installs a patent-pending basement waterproofing and foundation repair system engineered for Morris County’s climate and soil.
Our waterproofing system guarantees a dry basement for years to come and will never fail, even during the worst nor’easter storms. Here’s what makes our waterproofing system different:
In Randolph, the primary cause of a wet or leaky basement isn’t flooding—it’s hydrostatic pressure. When heavy rain or snowmelt soaks into the soil around your foundation, that water pushes outward with thousands of pounds of force. Over time, this leads to:
Many homeowners dismiss small cracks as “cosmetic,” but in Randolph’s wet climate, they rarely stay small for long. Once water finds a way in, it accelerates damage, and repair costs only climb higher.
That’s why United Waterproofing addresses both water intrusion and the structural causes of wall cracking. By combining drainage, reinforcement, and repair, we protect your home before costly foundation replacement becomes necessary.
Unlike companies that rely on patchwork solutions, United Waterproofing delivers comprehensive protection designed for New Jersey’s challenging climate. Our system stops water at the source while reinforcing your foundation for lasting stability.
Our solutions include:
With 25+ years of expertise, all installations are performed by in-house crews—not subcontractors—and backed by our 3-Year Workmanship & Materials Warranty.
