Our story
A dedicated waterproofing division, built on a 20-year reputation
RDC Waterproofing didn’t start from scratch. It grew out of the RDC brand — the New Jersey company homeowners have trusted for over 20 years and rated five stars more than a thousand times. As demand for basement waterproofing and foundation work grew, we built a dedicated division for it: specialists who do nothing but keep water out and foundations sound, with the same crews, the same standards, and the same reputation behind every job.
That heritage matters because waterproofing is a trust business. A wet basement is stressful, the work is invisible once it’s finished, and too many companies sell one expensive system to every house. We built RDC Waterproofing to be the opposite of that — a team that diagnoses the real problem first, recommends only what your home needs, and warranties the fix for the life of the structure.
Meet the founder
Russell Calderone, Founder
Russell Calderone has directed basement waterproofing and foundation repair across New Jersey for more than 20 years. He is known for one thing above all: finding the true source of water intrusion instead of upselling a system the homeowner doesn’t need.
- Diagnosis first: Russell trained the RDC crews to trace exactly how water enters — hydrostatic pressure, cracks, the cove joint, or grading — before recommending a fix.
- Named methods, real engineering: interior French drains to a sump, polyurethane and epoxy crack injection, carbon-fiber straps, wall anchors, piers, and exterior membrane systems.
- Accountability: our own crews on every job, a written warranty, and a fixed price with no surprises.
How we work
We fix the source — we don’t upsell
The philosophy behind every RDC inspection, quote, and installation.
Fix the source, not the symptom
We trace where water actually gets in and fix that — so you’re not bailing out the same basement every spring. Reviewers routinely say we found the real cause others missed.
Honest diagnosis, no upselling
If a $400 crack repair solves it, we won’t sell you a $12,000 system. Our reviews are full of homeowners who paid less than they expected.
Our own crews, every job
No rotating subcontractors. Trained RDC technicians do the work, so quality and accountability stay in-house.
Warrantied for life
Interior waterproofing systems carry a lifetime transferable dry-basement warranty — and it stays with the home when you sell.
Fixed price, in writing
Itemized, fixed-price quotes with no hidden fees and no day-of surprises — plus flexible financing on approved credit.
Free inspections, 7 days a week
We inspect inside and out and diagnose the source at no cost, any day of the week, with zero pressure.
