Basement Waterproofing Contractors You Can Trust
Protect Your Home, Your Health, and Your Investment
When water finds its way into your basement, it doesn’t just stop there. It seeps into your foundation, damages floors and walls, and creates the perfect breeding ground for mold. As one of the most trusted basement waterproofing companies in New York, Zavza Seal helps you stop moisture at the source – and keep it out for good.
Why Basement Waterproofing Matters
A wet or damp basement is more than a nuisance – it’s a sign your home is under threat. Water intrusion can weaken your foundation, lower your property value, and expose your family to dangerous mold spores. The longer you wait, the worse (and more expensive) the damage becomes. That’s why Zavza Seal offers complete basement waterproofing services tailored to your home’s specific needs.

Basement Waterproofing FAQ
Q: How much does basement waterproofing cost?
A: The cost varies based on the size of your basement, the source of the leak, and whether you need interior or exterior waterproofing. We provide free estimates tailored to your specific situation.
Q: What is the difference between interior and exterior basement waterproofing?
A: Interior basement waterproofing manages water after it enters your home — using drains, sump pumps, and sealants. Exterior basement waterproofing stops water before it gets in by sealing the foundation from the outside.
Q: Does waterproofing my basement increase home value?
A: Yes – a dry, mold-free basement improves your home’s value, livability, and appeal to potential buyers. It also prevents costly future repairs.
Q: Is waterproofing basement paint effective?
A: Waterproofing paint can help with minor dampness but isn’t a solution for serious water intrusion. For lasting protection, a full system is often necessary.
Q: How long does basement waterproofing last?
A: With Zavza Seal’s expert workmanship and high-quality materials, our solutions are built to last – and we back them with a 50-year warranty.
Q: How do I know if I need basement waterproofing?
A: Common signs include damp walls, mold, musty odors, visible cracks, or water pooling after rain. If you’re unsure, we offer free inspections.
Q: How long does a basement waterproofing project take?
A: Most projects are completed in 1 to 3 days, depending on the size of your basement and the complexity of the solution.
Q: Can I waterproof my basement myself?
A: DIY waterproofing may offer short-term relief, but without professional tools and expertise, it often fails to address the root cause. Professional service is more reliable.
Q: Will basement waterproofing stop all moisture?
A: When done properly, basement waterproofing significantly reduces – and often eliminates – moisture issues. Our solutions target the source to ensure long-term results.
Q: Is your 50-year warranty transferable to new homeowners?
A: Yes, our 50-year waterproofing warranty is fully transferable, adding value to your property if you choose to sell.
Q: Do you offer financing for basement waterproofing?
A: Yes, we offer flexible financing options to make your waterproofing project more affordable.
Q: Can waterproofing fix existing foundation cracks?
A: Yes, we repair and seal foundation cracks as part of the waterproofing process to prevent further water intrusion and structural damage.
Q: Do you use sump pumps as part of interior waterproofing?
A: Absolutely. Sump pumps are a one of the core components of interior basement waterproofing systems and help redirect water safely away from your home.
Q: What kind of maintenance is needed after waterproofing?
A: Minimal maintenance is required. We recommend annual check-ups of sump pumps and drainage systems to ensure they function properly.
Q: Are your materials environmentally friendly?
A: Yes, we use high-quality, low-VOC and environmentally conscious products whenever possible to protect your home and the planet.
