Basement Waterproofing

Connecticut homes get wet basements. It’s not bad luck. It’s geology. Clay-heavy soil, ledge rock, high water tables, and freeze-thaw winters create the perfect conditions for water to find its way into your foundation. CT Dry Basements has been solving that problem for homeowners across Connecticut for over 35 years.

We’re a locally owned, Connecticut-based company. We show up on time, give you honest options, and back our work with a lifetime guarantee. No upselling, no scare tactics, just real solutions that work.

Understanding the Problem

Why Connecticut Basements Get Wet

Connecticut’s housing stock is one of our greatest assets. Colonials, Cape Cods, Ranches, and Craftsman-style homes built throughout the 20th century. But those homes were built on stone or poured concrete foundations that have had decades of New England weather working against them.

The problem isn’t just age. Connecticut’s soil is heavily clay-based, which means it absorbs and holds water rather than letting it drain away. Add in the ledge rock that deflects groundwater toward your foundation, naturally high water tables throughout Hartford and New Haven counties, and the freeze-thaw cycles that hammer foundations every winter — and it’s a near-perfect recipe for a wet basement.

Clay Soil & Poor Drainage

Water saturates the soil and finds its way through the path of least resistance — your foundation walls.

Foundation Cracks

Both poured concrete and stone foundations crack and shift over decades, opening water entry points.

Hydrostatic Pressure

Saturated soil pushes against your foundation walls and forces water through floor joints.

Failed or Aging Sump Pumps

Many West Hartford homes have outdated pump systems that were never quite adequate — or have simply worn out.

Leaking Hatchways & Windows

Improperly sealed entry points let water in every time it rains — and they’re often overlooked.

Spring Snowmelt

When Connecticut winters break, the resulting runoff hits foundations hard and fast.

What We Do

Our Basement Waterproofing Solutions

We take a custom approach to every job. After inspecting your basement, we’ll walk you through exactly what’s happening and what options make sense for your home and budget.

White insulated pipes run along a concrete ceiling in an industrial utility space.

Interior Drainage Systems

Perimeter drainage channels collect water before it damages your floor or belongings, and route it safely to a sump pump. Not a patch — a permanent fix.

Sump Pump Installation

Dependable sump pump systems, including battery backup units so you’re protected when the power goes out — right when you need it most.

Foundation Crack Repair

We repair cracks in poured concrete and stone foundations with methods designed to hold — not just cosmetically cover the problem.

Crawl Space Encapsulation

Commercial-grade vapor barrier, sealed walls, and drainage solutions — so your crawl space stays dry, mold-free, and properly sealed year-round.

Mold Remediation

Water plus time equals mold. We handle remediation as part of the waterproofing process so you’re starting completely clean — not just dry.

Hatchway & Window Repair

Leaking bulkhead doors and aging basement windows are a common, fixable problem. We seal or replace them so every entry point is tight.
