Egress Window Installation London Ontario

Installing a basement egress window may sound easy, but there is a lot more to it than just cutting a hole and installing the new egress window. There are structural concerns, especially when increasing the existing window width or cutting in a new opening, and the wall and header must be addressed to meet building code requirements for an egress window.

There is also drainage concerns, the egress window area has to be excavated all the way down to the base of the homes foundation or footing to tie into your homes existing drainage system, then a drainage tile from the egress window well area is installed into the existing drainage system to prevent the window well from flooding into the basement or holding water that might freeze the window shut in the winter. There will also have to a good amount of gravel used after excavation, again to aid in the drainage of the egress window well system.

  • The Basement Egress Window opening must be a minimum of *3.8 (24″ x 24″) to *5.7 (24″ x 36″) square feet. Not the window itself, but the escape area when fully opened. The egress window type also plays a big role here, a 32″ X 40″ slider window may seem to be large enough, but when you subtract the window frame, sash frames, screen frames and the fact that a slider window will slide open less than half the overall width it would be too small to meet egress window code requirements.
  • The Egress Window opening must be minimally *17 inches to 20 inches at the smallest width or height.
  • Egress windows must be easy to open from the inside without any advanced brainpower or strength-training. It must be the natural operation of the window and not a tilt in for cleaning opening size such as in a tilt-in slider that requires additional window usage understanding that may not be known or easy to operate for some individuals.
  • The Egress Window should not be a hopper type that opens to the inside from the top down, you don’t want to have to crawl over a glass sash to get out of the egress window.
  • You must have a large Egress Window Well. Minimum 36″ wide from the glass of the opened egress window to the outside of the area well. At least 9 square feet of clear space in the area egress window well is required.
  • Egress Window Wells installed more than *36 inches to 44 inches deep should have steps or ladder to climb out.
  • TThe Egress Window Well should extend at least *4 inches on all sides of the window to prevent water damage and wood rot around the window, and it is better to use a vinyl window installed to the foundation without wood exposed to the exterior on the frame.
  • There must be at least one basement egress window on the basement level, some municipalities allow for a common basement egress window and other municipalities require a basement egress window in each bedroom. Where there are more than one apartment in a basement area there will always have to be a basement egress window in each apartment.
  • There MUST be proper egress window well drainage including excavating down to the base or footing of the foundation and tying into the existing drainage system around the home.
