Basement Windows

Basement Windows in Portland, Oregon

Basement windows are often overlooked when it comes to home design and remodeling—but they shouldn’t be. These small but mighty features play a big role in how your lower level functions, feels, and even smells. Whether you're updating an existing home or finishing a basement for the first time, installing or replacing your basement windows is one of the most valuable upgrades you can make. From better natural light and airflow to increased energy efficiency and resale value, the benefits speak for themselves.

At Portland Egress Window, we specialize in high-quality basement window installation throughout the Portland metro area. Every window we install is tailored to your home’s architecture, your specific goals, and the needs of your space. We’ve been in the construction and remodeling business for years, and we take pride in every basement window we install—because when done right, they don’t just perform better, they look better too.

Why Homeowners Upgrade Their Basement Windows

Basements are notorious for feeling dark, damp, and cut off from the rest of the house. A big reason for that is outdated or undersized windows. Many older Portland homes have small, single-pane units that barely let in light and don’t open easily—if at all. Over time, these windows become sources of drafts, leaks, and even mold.

Modern basement windows solve these problems by letting in more daylight, improving ventilation, and creating a stronger seal against moisture and cold. The result is a more livable, enjoyable basement space. For families looking to finish a lower level into a game room, guest suite, or home office, new windows are often the first step toward transforming that space.

Our Process: From Window Selection to Final Trim

At Portland Egress Window, we handle every part of the basement window installation process. From the initial site visit to the final trim work, our in-house team makes sure nothing is overlooked. We’ll walk you through the options for window type, size, frame material, and placement, and then get to work measuring and ordering your custom units.

Most of the time, we replace basement windows with insulated vinyl sliders, which are energy efficient, easy to clean, and designed to last. We install windows that fit the existing opening, or we can enlarge the window as part of a broader remodel. If your old windows are set in concrete or block walls, we’re fully equipped to handle the cutting, framing, and waterproofing necessary to ensure a tight fit.

Once installed, we finish out the trim and interior framing so that the window looks like it’s always been part of the home. We also make sure the area around the window is properly sealed, flashed, and graded to help protect your basement from water intrusion.

Designed for Portland Homes

Basement windows in the Pacific Northwest have to work a little harder than in other parts of the country. Between the rain, the damp winters, and the older housing stock found across Portland, we see a wide range of challenges in the field. That’s why our windows are designed with local conditions in mind.

We use materials that can stand up to constant moisture, including rot-resistant frames and proper drainage solutions. We’re also familiar with the quirks of Portland’s older homes—from post-war bungalows to mid-century ranches—and we know how to match the style and proportions of your home so your new windows look like they belong.

Whether you’re in Southeast Portland, Beaverton, Gresham, or out in Lake Oswego, we bring the same level of care and craftsmanship to every job.

Better Light. Better Air. Better Basement.

Even if you don’t spend a lot of time in your basement, the quality of your windows can make a surprising difference in how your entire home feels. Replacing old or damaged windows can help reduce musty odors, minimize condensation, and eliminate hot or cold spots.

But more than anything else, homeowners love the difference in light. You’ll be amazed at how much brighter and more welcoming a basement can feel once new windows are installed—especially when you choose larger units or open up the window well to bring in more sunshine.

Egress Window Well Installation

In some cases, we pair basement windows with new or updated window wells. If your current well is rusting out, doesn’t drain properly, or just looks like an afterthought, it might be time for an upgrade. We install galvanized steel, concrete, or decorative stone-look wells that are deep enough to meet code and designed to handle water runoff.

For customers planning to use the basement as finished living space, window well upgrades are a must. Not only do they improve the look from the inside and outside, but they also help keep water and debris away from the home’s foundation.

Full Remodel or Simple Swap? We Do Both.

Some clients come to us as part of a larger basement remodel, while others just want to replace a single broken window. No matter where you are in the process, we can help. We regularly work with homeowners, designers, and contractors to make sure the right windows go in the right places.

Need to turn a small, outdated hopper window into something more modern and functional? We’ve done that more times than we can count. Want to expand a narrow slider into a wide picture window with operable sides? We’ll design it, cut the wall, and install it to perfection.

City of Portland Rules & Requirements

If you’re upgrading or enlarging basement windows in Portland, it’s important to understand the local building codes. While simple replacements may not require a permit, cutting into the foundation, altering the structure, or adding egress features will.

Portland requires that all habitable basement spaces have proper light, ventilation, and emergency escape options. If your basement window serves a bedroom or living space, there are specific requirements around window size, sill height, and well dimensions. We help guide you through the process and ensure everything is up to code and ready to pass inspection.

As a licensed and bonded general contractor and FIR-approved installer, we work closely with Portland’s inspectors to keep projects moving and compliant.

Egress vs. Standard Basement Windows

Wondering what the difference is between a regular basement window and an egress window? It comes down to size, access, and safety. Egress windows must meet minimum width and height dimensions to allow for emergency escape. They also require a window well with proper clearance and a ladder or steps if the depth exceeds 44 inches.

Not every basement window needs to be egress—but if you’re creating a bedroom or adding finished square footage, it’s often required. We can help you determine which windows need to be upgraded and walk you through the options for bringing your space into compliance.
