SEAL OUT LEAKS
Basement Window Replacement & Sealing
Old or poorly sealed basement windows are a hidden source of trouble in many homes. Cracks, corrosion, and unsealed edges can let in water, cold air, pests, and humidity—leading to mold, structural damage, and higher energy costs. Replacing these windows and sealing them properly is one of the simplest ways to improve your home’s comfort, efficiency, and protection. Homeowners throughout Western Massachusetts and Northern Connecticut trust this upgrade to prevent leaks and keep their basements dry, clean, and secure.

Basement windows might be small, but the problems they cause when left unsealed or damaged can be anything but. These windows sit low to the ground, which means they’re more exposed to rainwater, snowmelt, and soil moisture. If the seals around them break down—or the glass or frame is cracked—it creates an easy entry point for leaks, drafts, humidity, and even pests.
Replacing or sealing basement windows protects more than just the opening itself. It helps prevent mold, reduces moisture buildup, improves air quality, and makes your basement more energy efficient. Whether you use your basement as storage or living space, properly installed windows keep it dry, secure, and comfortable year-round.
Signs You Need to Replace or Seal Your Basement Windows
Many homeowners don’t realize their basement windows are the source of their moisture problems—until it’s too late. A small crack or loose seal may seem minor, but it can lead to water damage, air leaks, and mold buildup if ignored. Knowing what to look for can help you avoid expensive repairs down the road.
Signs you need to replace basement windows:
Water pooling or streaks near the window frame
Glass that’s foggy, cracked, or hard to see through
Noticeable drafts or temperature swings in your basement
Rust, rot, or flaking paint on the frame or sill
Pests, insects, or moisture getting in through visible gaps
Mold, mildew, or musty odors near the window area
If any of these sound familiar, sealing or replacing your basement windows could be the solution. It’s a small upgrade that can make a big difference in how your basement looks, feels, and performs.
What We Do & How We Do It
Built to Seal, Built to Last
When it comes to basement windows, a quality install is about more than just putting in new glass. We take the time to assess the full area—inside and out—so your new windows do what they’re supposed to: keep water out, keep drafts out, and stay solid for years to come.
Our process starts with a thorough inspection of your existing window, frame, and surrounding masonry. If replacement is needed, we carefully remove the old unit and prep the opening for a clean, secure fit. We then install high-quality basement windows that are properly sized and designed to resist moisture and weather exposure.
Each window is professionally sealed with waterproof caulking and insulation to prevent air leaks and water seepage. If there are signs of drainage issues or previous water damage, we’ll recommend additional solutions to protect the area. You get peace of mind knowing your basement is better protected—inside and out.

FAQ's
Basement Windows FAQ's
Replacing or sealing basement windows can raise a lot of questions—especially if you’re not sure where the problem is coming from. Here are answers to some of the most common things homeowners ask us before getting started.
Can I seal my basement windows without replacing them?
In some cases, yes. If the window is structurally sound but leaking around the edges, resealing may be enough. We’ll inspect the area and let you know what makes the most sense.
Will new basement windows help prevent leaks?
Absolutely. New windows that are properly installed and sealed keep moisture out and help protect your basement from future water damage.
What kind of windows do you install?
We use high-quality, moisture-resistant windows made specifically for basement conditions. They’re built to be durable, energy-efficient, and secure.
Do you also fix window wells or drainage issues?
Yes. If your leaking window is caused by poor drainage or a faulty window well, we can repair or replace those too as part of a complete waterproofing solution.
How long does the installation take?
Most basement window replacements can be completed in just a few hours. We work efficiently and cleanly so there’s minimal disruption to your home.
