What a Dry Basement Actually Gets You

You’ll walk downstairs without that knot in your stomach wondering what you’ll find. No more musty smell hitting you at the bottom of the steps. No more moving boxes to higher shelves every time rain’s in the forecast.

Your basement becomes actual usable space again. Whether that’s storage you can count on, a workshop that stays dry, or finished living space that doesn’t make guests wrinkle their nose. The air upstairs gets cleaner too since you’re not dealing with moisture and mold spores cycling through your home’s ventilation.

And when those heavy spring rains hit or the snow starts melting fast, you’ll actually sleep through the night instead of lying there listening for the sound of water where it shouldn’t be.

Groton Foundation Waterproofing Experts

We Know Groton Basements Inside and Out

We’ve been handling foundation and waterproofing work in Groton and surrounding areas for years. We’ve seen what happens to basements here when the water table rises in spring, when those sudden summer storms hit, and when freeze-thaw cycles create new cracks in older foundations.

Most of our calls come from homeowners who’ve tried the DIY route or hired someone who didn’t understand how water moves around New England foundations. We get it right the first time because we know what works in this area and what doesn’t.

You’re not getting a sales pitch from us. You’re getting an honest assessment of what’s causing your water problems and what it’ll actually take to fix them permanently.

Our Basement Waterproofing Process

Here's Exactly How We Stop the Water

First, we figure out where the water’s actually coming from. That means looking at your foundation walls, checking for cracks, examining how water flows around your house, and understanding what’s happening below ground. Most water problems have more than one cause.

Next, we address the source. That might mean sealing cracks with professional-grade foundation sealers, applying waterproof sealant for basement walls, or installing proper drainage systems. Sometimes it’s interior waterproofing, sometimes exterior, often both.

We use materials that are designed for New England conditions – products that can handle freeze-thaw cycles and won’t fail when the ground shifts. Then we test our work to make sure water goes where it’s supposed to go, which is anywhere but your basement.

What's Included in Real Waterproofing

You get a thorough assessment of your specific water problem, not a one-size-fits-all approach. We look at interior and exterior factors, check your foundation’s condition, and identify every point where water might be getting in.

Our waterproofing work includes crack repair using professional-grade sealers, application of waterproof barriers where needed, and proper drainage solutions if that’s part of the fix. We’re not just slapping some sealant on your walls and calling it done.

You’ll understand exactly what we’re doing and why. We explain what caused the problem, how our solution addresses it, and what you can expect going forward. No surprises, no upselling, no coming back in six months because the fix didn’t hold.

How much does basement waterproofing cost in Groton?

The cost of basement waterproofing depends on what’s actually causing your water problem and how extensive the solution needs to be. Simple crack sealing might run a few hundred dollars, while comprehensive interior and exterior waterproofing can cost several thousand. Most Groton homeowners spend between $1,500 and $5,000 for permanent solutions. We give you an honest assessment upfront so you know what you’re looking at. The real cost is what happens if you don’t fix it – damaged belongings, mold problems, and foundation issues that get worse over time.

What's the difference between interior and exterior basement waterproofing?

Interior waterproofing works from inside your basement – sealing walls, installing drainage systems, and managing water that’s already trying to get in. Exterior waterproofing stops water before it reaches your foundation walls by applying waterproof barriers and improving drainage around your house. Interior is usually less expensive and easier to access. Exterior is more comprehensive but requires excavation. Many Groton homes need both because our soil conditions and weather patterns create pressure from multiple directions. We’ll tell you which approach makes sense for your specific situation.

How long does basement waterproofing take to complete?

Most interior waterproofing jobs take 1-3 days depending on the size of your basement and what needs to be done. Exterior work takes longer – usually 3-5 days – because we need to excavate around your foundation. Weather can affect timing, especially for exterior work. We don’t rush the job because shortcuts lead to callbacks. You’ll know the timeline upfront, and we stick to it unless we discover something unexpected. The disruption is temporary, but the results last for decades when done right.

Will waterproofing work if my basement floods every spring?

Yes, but only if we address what’s actually causing the flooding. Spring flooding in Groton usually happens because of rising water tables, poor drainage around the foundation, or cracks that let groundwater through. We need to figure out your specific cause and design a solution that handles it. That might mean exterior drainage, foundation sealing, interior water management, or all three. Band-aid fixes won’t work for recurring floods. You need a system that can handle Groton’s spring conditions year after year.

Can you waterproof a basement that already has mold problems?

We handle the waterproofing part – stopping the moisture that’s feeding the mold growth. The mold remediation needs to be done by specialists, either before or after our waterproofing work depending on the situation. What we can tell you is that waterproofing without fixing the mold problem first sometimes traps moisture and makes things worse. And mold remediation without waterproofing just means the mold comes back. The two need to work together. We can coordinate with mold specialists or recommend when to sequence the work properly.

Do you guarantee your basement waterproofing work?

Yes, we stand behind our waterproofing work because we use proven methods and quality materials. The specific warranty depends on what type of work we’re doing – crack repairs, sealant applications, or drainage systems all have different expected lifespans. We’ll explain exactly what’s covered and for how long before we start. What we don’t do is make unrealistic promises about stopping every drop of moisture forever. We guarantee our workmanship and materials, and we’ll come back if something fails that shouldn’t have. That’s how you know you’re working with contractors who do this right.
