Here's Exactly What Happens

First, we’ll come out and actually look at your specific situation. Not a quick glance – a real assessment of where water’s getting in, why it’s happening, and what needs to happen to stop it.

You’ll get a clear explanation of what we found and what we recommend. Interior waterproofing, exterior waterproofing, or both – whatever your basement actually needs, not what’s easiest for us.

Then we do the work using professional-grade sealers and materials that are designed to last. You’ll know exactly what’s happening and when, because nobody likes contractors who disappear for days without explanation.

What You Actually Get

Complete basement waterproofing services that address your actual problem. Interior basement waterproofing for existing water issues. Exterior basement waterproofing when the problem needs to be stopped at the source.

Professional basement wall sealer application that creates a real barrier against moisture. Not the stuff you can buy at the hardware store – the materials that actually work for Long Island conditions.

Emergency response when your basement floods and you need someone there fast. Because water damage doesn’t wait for business hours, and neither do we when you’re dealing with an urgent situation.

Interior basement waterproofing handles water that’s already getting through your foundation walls. We apply professional-grade sealers to the inside surfaces and can install drainage systems if needed. Exterior waterproofing stops water before it reaches your foundation by sealing the outside walls and improving drainage around your home. Many Brightwaters homes need both approaches because of our clay soil conditions. Interior work is less disruptive and often handles most water problems, while exterior work is more comprehensive but requires excavation around your foundation.
Professional basement waterproofing should last 10-15 years minimum when done correctly with quality materials. The key is using the right approach for your specific situation and not cutting corners on materials. We use commercial-grade basement sealers that are designed for Long Island’s conditions, not consumer products that might last a year or two. Your results depend on factors like your home’s age, soil conditions, and drainage around your property. We’ll give you realistic expectations based on what we see during our assessment, not generic promises that don’t mean anything.
Yes, but we need to address why it keeps flooding first. Repeated flooding usually means the previous attempts didn’t identify the real source of water intrusion. We’ll assess your foundation, drainage, and soil conditions to understand what’s actually happening. Sometimes it’s failed exterior waterproofing, sometimes it’s inadequate interior sealing, and often it’s both. The good news is that even basements with a history of flooding can be permanently fixed with the right combination of interior and exterior waterproofing approaches. We’ve solved water problems for plenty of Brightwaters homeowners who thought their basements were hopeless cases.
First, turn off electricity to the basement if there’s standing water – safety comes first. Remove any belongings you can safely reach, then call us for emergency service. We respond quickly to water emergencies because time matters when you’re dealing with flooding. Don’t try to seal walls while they’re actively leaking – that’s a temporary fix that usually makes the real problem worse. We’ll help you stop the immediate water intrusion and then develop a plan to prevent it from happening again. Emergency waterproofing is about stopping damage now and solving the underlying problem permanently.
Basement waterproofing costs depend on your specific situation – the size of your basement, severity of water problems, and whether you need interior work, exterior work, or both. Interior basement sealing typically costs less than exterior waterproofing, but many Long Island homes need comprehensive solutions. We provide detailed estimates after assessing your basement because generic pricing doesn’t help you make an informed decision. What we can tell you is that professional waterproofing costs significantly less than dealing with repeated flooding, mold remediation, or structural damage from ongoing water problems.
Yes, we stand behind our waterproofing services because we use proven methods and quality materials. The specific warranty depends on the scope of work and materials used, which we’ll discuss during your estimate. What’s more important than warranty length is doing the job right the first time with proper assessment and appropriate solutions. We’ve been waterproofing basements in Long Island long enough to know what works and what doesn’t. Our goal is waterproofing that lasts so long you forget you ever had water problems, not work that barely makes it past the warranty period.
