bulkhead doors that are secure, durable and weather resistant

An old or poorly fitted bulkhead door is more than an eyesore — it’s an open invitation for water, pests, and cold air to move into your basement. Gaps around the frame, deteriorated seals, and warped panels are among the most common and most overlooked contributors to wet, drafty basements. Keller’s bulkhead door installations start with the right fit for your specific entry — whether your access is flat to the ground or set into a sloped grade — and finish with a door that locks tight, sheds water, and stands up to whatever your climate demands. With a range of styles and colors to choose from, you don’t have to sacrifice curb appeal to get real performance at your basement entry.

Turn Your Basement Into Legal, Livable space

We Saw Cut Openings and Install Egress Windows With Wells

A finished basement is only as valuable as it is legal — and without a proper egress window, that bonus bedroom, home office, or in-law suite may not meet code. We handle the entire process from start to finish: precision saw cutting through your foundation wall, installing a code-compliant egress window, and fitting a properly sized window well so the space is safe, bright, and ready for whatever you have planned. No subcontracting, no guesswork — just a clean installation done right from New England professionals with over 50 years of experience.

Full-service installation — we handle the saw cutting, window installation, and window well placement so you have one contractor, one timeline, and one point of accountability
Precision concrete saw cutting creates a clean, structurally sound opening without the mess and risk of jackhammering or improper demo
Meets IRC egress requirements — minimum opening size, sill height, and well dimensions are built into every installation, keeping your project code-compliant and insurable
Transforms non-conforming basement rooms into legal bedrooms — a single egress window can unlock thousands of dollars in appraised home value
Window wells keep the opening protected — properly installed wells prevent soil erosion, water intrusion, and debris buildup around your new window
Dramatically increases natural light in spaces that previously had no window at all
Critical life-safety feature — in the event of a fire or emergency, egress windows provide an accessible escape route for occupants and an entry point for first responders
Pairs seamlessly with our vinyl window installations for a finished, uniform look throughout your basement

Professionally Installed Basement Vinyl Windows

Let The Light In; Keep The Elements Out

Your basement shouldn’t feel like a cave. Our professionally installed basement vinyl windows bring in natural light while delivering serious performance — double pane glass with Low-E coating keeps your basement comfortable year-round, reduces energy loss, and adds real value to your home. Whether you’re finishing your basement, replacing aging single-pane windows, or simply upgrading for efficiency, we have the right opening style to fit your space and your needs.

Double pane insulated glass creates a thermal barrier that keeps cold air out in winter and heat out in summer — reducing strain on your HVAC system
Low-E (low emissivity) coating reflects infrared and UV light, protecting your belongings, flooring, and furnishings from sun damage while cutting energy costs
Vinyl frames never rot, rust, or need painting — a low-maintenance solution built to last in the damp, variable conditions of a basement environment
Improved natural light transforms dark, uninviting basement spaces into functional, livable areas
Enhanced moisture resistance helps protect against condensation buildup — a common problem with older single-pane basement windows
Tight seals and weather-stripping reduce drafts and keep pests, moisture, and outdoor air where they belong — outside
Increased home value — energy-efficient windows are a recognized selling point that appeals to today’s buyers
Code-compliant egress options available for finished basements requiring safe emergency exit points

Things You Need To Know About Basement Waterproofing

What types of basement opening services does Keller provide?

Keller handles everything related to your basement’s connection to the outside world. We install double pane, Low-E basement vinyl windows in a variety of opening styles, saw cut new openings and install egress windows with window wells, and supply and install secure, weather-resistant bulkhead doors for both flat and sloped entries. Whether you need one service or all three, we manage the entire installation from start to finish.

How do I know if my basement needs an egress window?

If you have — or plan to have — a sleeping area in your basement, building code requires an egress window that meets minimum size, height, and accessibility standards. Beyond code compliance, egress windows are a critical life-safety feature, providing an emergency escape route for occupants and an entry point for first responders. If your basement currently has no window or only a small utility window in that space, it almost certainly doesn’t meet egress requirements.

What does the saw cutting process involve, and will it damage my foundation?

Saw cutting is a precise, controlled process that uses professional-grade equipment to create a clean opening through your foundation wall. When done correctly it does not compromise your foundation’s structural integrity — the opening is properly framed and reinforced as part of the installation. This is very different from older methods like jackhammering, which create unnecessary stress and mess. Our crews are experienced in foundation cutting and take every precaution to protect your home throughout the process.

What is Low-E glass and why does it matter in a basement?

Low-E (low emissivity) glass has a microscopically thin coating that reflects infrared and UV light while still allowing natural light to pass through. In a basement, this means reduced heat loss in winter, less heat gain in summer, and protection for flooring, furniture, and stored belongings from UV damage. Combined with double pane construction, Low-E windows significantly outperform older single-pane basement windows on both comfort and energy efficiency.

Can a poorly fitted bulkhead door really contribute to a wet basement?

Absolutely. Gaps around the frame, deteriorated seals, and warped or aging panels are some of the most overlooked entry points for water intrusion in a basement. A bulkhead door that doesn’t fit properly for your specific entry — whether flat or sloped — will allow water, drafts, and pests inside regardless of what else you’ve done to waterproof the space. Proper installation with the right door for your configuration is the only way to ensure a tight, lasting seal.

Does upgrading basement windows, adding an egress window, or replacing a bulkhead door add value to my home?

Yes — all three can have a measurable impact on your home’s value and marketability. An egress window can convert a non-conforming room into a legal bedroom, which directly affects your appraised square footage. Energy-efficient vinyl windows are a recognized selling point with today’s buyers. And a clean, secure, properly fitted bulkhead door improves curb appeal and signals to buyers that the home has been well maintained. Together, these upgrades signal a basement that’s been treated as livable, protected space — not an afterthought.
