Egress Window Frequently Asked Questions

How much does an egress window cost?

The cost of an egress window varies based on its specifications and other installation variables, but the Bright Idea Egress solution is specifically designed to be more cost effective than traditional solutions, with our complete egress window kits starting at $1300 and install process engineered for additional cost savings.

The Bright Idea Egress window kit design requires less excavation than any other solution. The most significant labor component in egress window installation is excavation, which involves not only digging the dirt out but a corresponding effort in backfilling and hauling excess dirt away. The amount of dirt removed not only translates into cost, but also into potential risk to your foundation. Our patented steel Exo-Frame and unique window well design with interior flanges involve significantly less excavation than any competitive solution, thereby resulting in a lower total cost.

If you're a capable DIY handyman and complete all the work, including excavation, the foundation cut and using one of our kits, your basic egress window starts at $1300.

If you do the dig, but outsource the foundation cut and egress kit installation to a contractor, we typically see a total installation cost using one of our kits starting at $2600.

And if you outsource all of the work, including excavation, to a contractor, we typically see a total project cost starting at $3600, including the use of our kit.

Please note that these estimates are using our smallest egress window kit, using a 29″ x 47″ European Tilt & Turn, and do not account for construction cost variances across local markets. We are happy to clarify any details of these estimates and answer any questions, please do not hesitate to ask!

How should I measure for an egress window?

Egress window code is a requirement intended to ensure a person can escape a building through a window in an emergency. Most codes also require windows to be large enough for a firefighter with his pack on to enter through them. The minimum standards of egress window sizes are uniformly dictated by building code requirements of the 2015 International Residential Code (IRC). The key concerns to conform with building code include:

  • A minimum clear opening width must be at least 20"
  • A minimum clear opening height must be at least 24"
  • A minimum clear opening size must be at least 5.7 square feet
  • The sills on egress windows can be no higher than 44 inches from the finished floor

This diagram illustrates these egress window minimum size and code requirements:

 

There are also the following code requirements for both natural light and ventilation in basement settings.

For natural light, the glass area, in square feet, must be at least 8% of the total floor area that the egress window is servicing. For example: If you had an egress window that has a glass area of 48" x 48" or 16 square feet, that would service an area up to 200 square feet. 16 square feet = 8% of 200 square feet. If the basement area you wish to have serviced by an egress window is larger than this 8% rule allows, you can use multiple egress windows to achieve the minimum 8% of glass area for natural light.

For ventilation, the window's clear open area, in square feet, must be at least 4% of the total floor area that the egress window is servicing. For example: if you had an egress window that has a clear opening of 24" x 48" or 8 square feet. That would be able to service an area no greater than 200 square feet. 8 square feet = 4% of 200 square feet. If the basement area you wish to have serviced by an egress window is larger than this 4% rule allows, you can use multiple egress windows to achieve the minimum 4% of clear opening size for ventilation.

How is the egress window kit shipped to me?

The Bright Idea Egress window kit is packed and wrapped on a shipping pallet, with our smallest kit size weighing in at approximately 300 pounds. When we calculate shipping costs, we ask if you require liftgate delivery at your shipping destination, or alternately if you can pick up the kit at a nearby shipping terminal. The latter option saves you some shipping cost involved with liftgate service.
