What We Do — Proven Waterproofing That Works
At United Waterproofing, we’re known for solving real water intrusion issues, not covering them up. Our full-service team handles everything from inspection to final cleanup.
Interior Basement Waterproofing
We install sump pumps and drainage systems that stop flooding from the inside. Our interior basement wall waterproofing options are ideal for finished basements & help protect your investment.
Exterior Basement Waterproofing
We create a full barrier around your home with exterior waterproofing systems. Using membranes, drains, and sealants, we stop water before it gets close to your foundation.
Storm Water Management
Our systems direct stormwater away from your foundation. Stop erosion, protect your slab, and avoid costly slab waterproofing and basement finishing services.
Sump Pump Installation
We install high-performance sump pumps with battery backups. You’ll get 8+ hours of runtime, an alarm system, and long-lasting protection.
Mold Mitigation
A wet basement can lead to mold growth in less than 48 hours. Our mold control services are fast, safe, and reliable.
Crawlspace Encapsulation
Seal your crawlspace to prevent moisture, odors, and pests. We’ll create a dry, healthy environment under your home.
