How long does egress window installation take?

Egress window installation typically takes 1-2 days for most Ottawa basement projects, though this can extend to 3-4 days depending on foundation conditions and weather.

The timeline breaks down into several phases. Day one usually involves the most intensive work - cutting through your foundation wall, which can take 4-6 hours depending on whether you have poured concrete, block, or stone foundation. Older Ottawa homes (pre-1960s) often have thicker stone foundations that require more time to cut through safely. The excavation outside your home adds another 2-3 hours, and contractors need to be mindful of utilities - many Ottawa neighborhoods have shallow gas lines or electrical services that require careful hand-digging around the window area.

Day two focuses on installation and finishing work. Setting the window well, installing the actual egress window, and ensuring proper drainage typically takes 4-5 hours. The interior finishing - framing, insulation, and drywall - adds another few hours. Weather plays a significant role in Ottawa's climate; rain can delay exterior work, and winter installations (while possible) take longer due to frozen ground conditions and the need for temporary heating during concrete work.

Several factors can extend the timeline beyond two days. If your basement sits below the water table (common in areas near the Rideau River or in Kanata's clay soil), additional waterproofing measures may be required. Homes built before 1980 might need asbestos testing if disturbing old window frames or insulation, adding 1-2 days for lab results. Access issues - like tight side yards or mature landscaping - can slow excavation work significantly.

Professional installation is essential for egress windows since they're life safety features that must meet Ontario Building Code requirements. The window well must be properly sized (minimum 9 square feet of opening), and the window sill can't be more than 44 inches above the basement floor. ESA permits aren't required unless you're adding electrical, but building permits are mandatory for egress windows in Ottawa.
