How to Repair and Replace Egress Windows in Portland, Maine

Repairing or replacing an egress window is much more challenging than dealing with a regular window in your Portland, Maine, home. That’s because you’ll need to comply with building codes, which specify strict requirements for window size and access.
While a do-it-yourself approach may sometimes work, consider working with an egress window professional who will handle the heavy lifting and provide lasting results.
What Are Egress Windows?
An egress window provides a safe means of escape from a home in the event of a fire, flood, or other emergency. Typically located in basements, they swing in and out to open and close like a door.
There are strict requirements for egress windows. Here in Maine, an egress window in a building constructed after 1976 should provide 5.7 sq. ft. of net clear opening with a minimum width of 20″ and a minimum height of 24″.
Complying with these rules is essential. If an egress window isn’t up to code, your home might fail an inspection if you sell it. Incorrect window measurements can also pose a safety risk in an emergency.
What Egress Window Problems Require Repair?
Here are some common egress window problems and how to fix them:

Cracked Window
A glass repair kit from the hardware store might be all you need to fix small cracks in an egress window. However, for larger cracks, we recommend contacting an expert. Placing window sealant over big cracks is a temporary fix, and you might need to replace the window entirely.
Leaky Window
A leaky window allows the outside elements, including rain and snowmelt, into your home, so you’ll want to fix it as quickly as possible. Caulk or weatherstripping may repair small gaps and drafts, but basement window replacement might be necessary for more extensive damage.
Sticking Window
If your window gets ‘stuck’ and doesn’t open or close properly, try cleaning its hinges and other hardware with a brush and soapy water. This could remove any dirt and debris that’s preventing the window from functioning.
Sticking windows (or doors) could indicate something more serious with your property, such as foundation damage, so you might want to have a professional check this out.
How Do You Replace an Egress Window?
You may decide to replace your entire window in the following circumstances:
- Your current window doesn’t meet building regulations
- The window has extensive damage, such as widespread cracks
- You don’t get enough insulation from your window
- The window is constantly leaking
Replacing an egress window will typically involve the following:
Removing the Original Window
This can be complicated, especially if the window is old or damaged. You’ll need to remove the original trim, cut through any existing sealing or caulk, and pull out the window’s frame.
Installing the New Window
Installing a new window requires sliding it into place and aligning it properly. Improper alignment can lead to drafts and leaks, so make sure it’s level and centered.
Sealing the Window
Sealing your new window can also prevent drafts and leaks and ensure heat doesn’t escape your home. Expandable urethane foam might provide you with additional insulation.
As you can see, the repair process can be complex, and it’s best to rely on professional egress window installers for the right solution.
