Question:
We will be adding on to our home with a full basement under the addition. Friends have recommended we consider egress window, but we cannot find a lot of information on them. Do they cause increased
security or drainage problems? Are they worth the extra expense? What are the options for the area well? Are there Companies that make custom grates or guard rails for them?
Answer:
The first question you should
ask yourself is will the basement area ever be used for sleeping? If not, an egress window may not be worth installing. If the basement will be used for sleeping, Wisconsin code requires 2 exits, one being the stairs and the
other may be a window.
However, there are a number of guidelines that must be followed to install an egress window to code.
1.) Naturally, the window, screen & storm must be able to be opened from the inside.
2.) The window opening must be at lease 20 inches wide by 24 inches tall (nominal size).
3.) No stops, stools, rails or operating arms can infringe on the required opening (except a moveable sash).
4.) The window opening must not be more than 46 inches off the floor or permanent platform.
5. ) If a platform is used, it must be as wide as the window with steps at a minimum 9 inch tread and 8 inch risers maximum.
6.)
The exterior well area must be at least as wide as the window, not more than 46" deep (below grade), and a minimum of 3 feet out from the basement wall measured perpendicular.
7.) The well must be constructed to prevent rainfall from entering the dwelling.
As long as you follow those guidelines, all the other decisions are yours. As far as security and drainage, the home is no less secure
because it has a window below grade. If thieves want to get in, they will get in with or without an egress window. If you install a grate over the opening (which you should), it is probably more secure than the other windows in
the house.
Yes, drainage could be a problem if the well is not constructed properly. The bottom of the well may need to be tied into the drain tile with gravel for proper drainage. I suggest you leave it to the
professionals if you are going to have it done.
The options for the well area are many. The standard and best way to go is with a masonry well (block & concrete), but it is also the most expensive. We recently did
one with railroad ties. You can use your imagination within reason, as long as a person can get out - that is the important thing. You may also want to construct a couple steps up for the smaller people.
I am not aware
of a Company who specializes in grates or guardrails for window wells. We always have had ours custom made to meet the specific needs of our clients. You will have to let your fingers do the walking there.
As far as
being worth the added expense, that depends on the individual. Will there ever be a fire? , maybe not. Is the safety of your family or guests worth a couple thousand dollars? Those decisions are yours. Just remember that if
your are going to do it, do it right, and check out your Contractor!
