Egress Window Wells in Denver: What They Are and Why You Need One

What Is an Egress Window Well?

If you’re a Denver homeowner looking to finish a basement bedroom or improve your home’s safety, you’ve likely heard the term “egress window well.” Simply put, an egress window well is the metal, concrete, or polypropylene structure that sits outside your basement window, below grade. It creates a space that allows the window to open fully, providing a safe exit route in an emergency.

In Colorado, building codes are strict about egress windows because of fire and carbon monoxide risks. The window well itself must meet specific size and depth requirements to ensure a person can climb out easily. For most Denver homes built before the 1990s, original basement windows are too small to meet modern code — which is where egress window well Denver installations come in.

Why Denver Homeowners Need an Egress Window Well

Denver’s building codes (based on the International Residential Code with local amendments) require every basement bedroom to have at least one egress window. The window well must be at least 36 inches wide and 36 inches deep, with a net clear opening of at least 5.7 square feet. If the well is deeper than 44 inches, it also needs a permanently affixed ladder or steps.

Beyond code compliance, here’s why you need one:

• Safety first: In a fire or gas leak, basement occupants need a second way out besides the stairs. An egress window well provides that escape route.
• Increase home value: A legal basement bedroom with proper egress can add significant resale value, especially in Denver’s competitive housing market.
• Natural light and ventilation: A larger window well allows more light into your basement, making it feel like a true living space. Plus, you can open the window for fresh air — something small basement windows rarely allow.
• Insurance benefits: Some insurers offer discounts for homes with proper egress, as it reduces risk during emergencies.

Denver-Specific Considerations: Soil, Weather, and Installation

Denver’s unique environment affects how egress window wells are installed and maintained. Here’s what you need to know:

Soil Types and Drainage

Denver sits on a mix of clay, sand, and gravel soils. Clay-heavy soil expands when wet and contracts when dry, which can shift window wells over time. That’s why we at Affordable Egress Co. always install a proper gravel base and drainage system — typically a perforated pipe connected to your home’s footing drains — to prevent water pooling. Without good drainage, a window well can become a mosquito haven or, worse, a source of basement flooding during spring snowmelt or heavy summer thunderstorms.

Front Range Weather

Colorado’s Front Range experiences freeze-thaw cycles, hail, and intense sun. Metal window wells can rust if not galvanized properly. Polypropylene wells are popular in Denver because they resist corrosion and UV damage. Concrete wells are durable but can crack over time if not reinforced. We recommend heavy-gauge galvanized steel or high-density polypropylene for most Denver homes — both hold up well against our climate.

Concrete Cutting Challenges

Many Denver basements are poured concrete or concrete block. Cutting a hole for an egress window requires precision — you need to avoid rebar, utility lines, and structural supports. Affordable Egress Co. has been doing this since 1999, so we know exactly how to cut cleanly and safely. Most of our installations, including concrete cutting, window installation, and window well placement, are completed in a single day. That means minimal disruption to your schedule.

What to Expect During an Egress Window Well Installation

If you’re considering a project, here’s a step-by-step overview of what happens:

1. Free estimate: We visit your Denver home, assess the basement layout, check local code requirements, and provide a written quote. No pressure, just honest advice.
2. Permitting: We handle all necessary permits with Denver or your local municipality. This ensures your installation passes final inspection.
3. Excavation: We dig out the area outside your basement wall, typically 4–6 feet deep, depending on your window placement.
4. Concrete cutting: Using a diamond-blade saw, we cut a precise opening in your foundation wall. This is done with minimal vibration to protect your home’s structure.
5. Window and well installation: We install a code-compliant egress window (usually a casement or sliding style) and secure the window well. We also add drainage gravel and a ladder if needed.
6. Backfill and finishing: The excavated area is backfilled, and we ensure proper grading so water drains away from your foundation. Most jobs are done by late afternoon.
7. Final inspection: We schedule a city inspection to confirm everything meets code.

Because we’ve been in business since 1999, our crews are efficient and experienced. You don’t need to worry about weeks of construction — just one day of work, and your basement is transformed.

Common Mistakes to Avoid When Choosing an Egress Window Well

• Going too small: Some contractors try to cut corners with undersized wells. Always verify the clear opening meets the 5.7 sq ft minimum (or 5.0 sq ft for floor-level windows).
• Ignoring drainage: A well without proper drainage will collect water and debris. Make sure your contractor includes a gravel base and drain pipe.
• Skipping permits: Unpermitted work can cause issues when you sell your home. Always insist on a permitted installation.
• Choosing the wrong material: Cheap plastic wells can crack in Denver’s sun. Invest in quality materials that last.
