Egress windows, basement windows and basement doors in Airdrie

Fitting windows and doors to Airdrie walls

Most Airdrie homes are recent, and for anyone choosing a basement window or door that is good news. The bulk of the houses we see here were built from the 1990s on, over poured concrete walls with steel in them — not the block or unreinforced concrete found in older Calgary neighbourhoods. A poured wall is uniform, so the new opening comes out square and true, and a window frame or door unit can be fitted and sealed against it without shimming around voids. It still is not guesswork: the rebar gets located before we fix the window’s position, because the bar pattern limits where the opening can go and what the steel lintel above it rests on. Wall thickness and reinforcement are confirmed on the visit, before any quote.

Where Airdrie really differs is under the lawn. North of Calgary the soil is a heavy clay that soaks up water, swells when wet and pulls back in dry weather, so the basement wall is already under seasonal pressure. Put an egress window in that wall and you have to dig a well right against it. Give that well no way out for water and snowmelt, downspout runoff and a lawn that slopes the wrong way all collect in it, the gravel at the bottom clogs with fines, and the new window ends up sitting at the bottom of a tank.

Undrained wells are the problem we get asked to fix in Airdrie more than any other — some never had a drain, others had one that silted shut. That is why, on this soil, the well is chosen along with the window instead of after it. We check for a working weeping-tile connection or build a sump that genuinely drains, backfill with clean stone rather than the excavated clay, fit a cover where snow and rain would otherwise pour in, and regrade the yard so water runs away from the opening. Sandier ground forgives a sloppy well for years. This clay does not.

What Airdrie homeowners are after

Airdrie calls about legal secondary suites more than any other place we serve. Plenty of commuters here pay Calgary-sized mortgages, and renting out the basement is a sensible way to carry one. What holds most of them up is the bedroom window the builder installed: fine for daylight, too small to count as egress. Either the clear opening with the sash open is under 0.35 m² (3.77 sq ft), or its narrower side is below 380 mm (15"). You cannot tell that by standing in the room, so most owners find out from an inspector, and then call us for a larger egress window and often a separate suite entrance door as well.

The other calls come from families adding a proper bedroom downstairs — for a teenager, or a parent moving in — and from sellers whose agent has said the lower room cannot be listed as a bedroom. The window that solves it is the same in each case. The priorities are not: a suite owner needs paperwork an inspector will accept, while a seller needs the yard put back before the photographer comes. At the site visit we tell you plainly which schedule is achievable.
