Cherry Hill & South Jersey
Permanent solutions for wet basements, seeping walls, and foundation cracks in Cherry Hill, NJ.
A wet basement is more than an inconvenience. Left unaddressed, water intrusion weakens your foundation, creates mold conditions, and reduces your home's value. Basement Waterproofing Cherry Hill installs drainage and sealing systems designed to keep your basement dry through every New Jersey rain season, not just the next one.
We install perimeter drain channels along the inside of your foundation footing that capture water as it enters and direct it to a sump pump. This is the most effective long-term solution for most South Jersey homes.
A properly sized sump pump is the heart of any waterproofing system. We install submersible pumps with battery backup options so your basement stays dry even during power outages — common in NJ storm seasons.
Hairline and structural cracks in poured concrete or block walls are sealed using polyurethane or epoxy injection. This stops water at the source without excavation in most cases.
Dimple-board or drainage matting installed against basement walls directs water down to the drain channel rather than allowing it to pool on the floor or wick into finishing materials.
When the exterior membrane has failed or the grading sends water directly toward the foundation, we excavate and apply a waterproof coating and new drainage board around the outside of the foundation wall.
Basement windows that collect water during heavy rain need proper drainage below the well. We install gravel beds and drain pipes that prevent window well flooding from pushing water into the basement.
Costs vary based on the size of the basement, the type of solution required, and the severity of the water problem. Below are general ranges to help you plan. A free inspection gives you an exact number.

We are not a general contractor who also does waterproofing. It is all we do — so every diagnostic and every system we install reflects deep, specific experience.
The owner inspects every job before a proposal is written. You get an honest assessment, not a sales pitch based on upselling a larger system than you need.
Camden County's clay-heavy soil holds water against foundations differently than sandy coastal soils. Our systems are selected and installed for what actually works here.
Every completed waterproofing system comes with a written warranty. We review terms before you sign and stand behind the work after we leave.
Tom visits your home, assesses the source and severity of the water issue, and documents what he finds — no charge, no obligation.
You receive a clear, itemized estimate with system options, timeline, warranty terms, and total cost — before any work begins.
Most interior drainage jobs are completed in one to two days. We protect your space, clean up fully, and confirm everything is working before we leave.
We check in after the first heavy rain season to confirm the system is performing. Questions after install are always answered — no hand-off to a call center.
