What You Need to Know About Basement Windows in Alberta

Get a permit through City of Calgary

Before installing a basement window or cutting through a foundation in Calgary, you’ll need to obtain the appropriate permits from the City of Calgary. Foundation modifications and new basement windows—including egress window installations—must comply with the Alberta Building Code and local fire and building safety regulations. Obtaining a permit ensures your project is professionally inspected, meets all required safety standards, and is approved by the City of Calgary, helping protect your home’s structural integrity and value.

How to obtain an egress window permit

Many Calgary basement window contractors can apply for your City of Calgary building permit on your behalf for an additional administrative fee. However, you’ll still need to provide the required documentation, including a site plan, basement floor plan, and written homeowner consent.

Since you’ll already have these documents prepared, many homeowners choose to apply for the permit themselves to save money. The City of Calgary’s online permit system makes the application process straightforward for most residential basement window and egress window projects.

Once your City of Calgary permit has been approved, your basement window installation or foundation cutting project can begin.

Contractor Experience Matters

Not all egress window contractors have the same level of experience. While egress windows have become increasingly popular over the last two decades, concrete foundation cutting requires specialized training, equipment, and expertise.

At CanWest Concrete Cutting & Coring, we’re often called to repair or replace improperly cut basement window openings after homeowners hired the lowest-priced contractor. In many cases, the contractor lacked the experience needed to safely cut concrete foundations or meet Alberta Building Code requirements.

When comparing egress window installation companies in Calgary, look for a contractor that:

• Has 30+ years of concrete cutting experience
• Specializes in foundation wall cutting and basement window installations
• Can provide photos of completed projects
• Understands Alberta building and fire code requirements
• Uses professional concrete cutting equipment

Choosing an experienced contractor helps ensure your project is completed safely, accurately, and to code the first time.

Egress Window Size Options

Not every contractor offers the same selection of egress window sizes. Before signing a contract, confirm they can supply and install the specific window dimensions that best suit your basement renovation and meet Alberta code requirements.

Alberta Egress Window Requirements

To comply with the Alberta Building Code, an egress window generally must meet the following requirements:

• Minimum unobstructed opening of 0.35 m² (3.77 sq. ft.)
• Minimum width or height of 380 mm (15 inches)
• Window well must project at least 760 mm (30 inches) from the foundation wall
• Window well should extend at least 2 inches above finished grade and generally no more than 6 inches
• Egress requirements may not apply where an approved sprinkler system is installed
• Windows installed beneath a cantilever must meet clearance requirements
• Windows installed beneath a deck require a minimum 2.1 m (7 ft.) clearance

Building code requirements can change, so always confirm current regulations with your contractor and local permitting authority.

Ask What’s Included in Your Quote

The lowest quote isn’t always the best value.

Some contractors only complete the exterior portion of the installation and leave homeowners responsible for:

• Interior framing
• Drywall repairs
• Interior trim
• Painting and finishing

This can make one quote appear less expensive while increasing your overall project cost. Always ask exactly what is included before work begins.

Discuss Window Well Drainage

Proper window well drainage is an important part of every egress window installation.

Depending on your property, contractors may recommend drainage solutions such as:

• Gravel drainage systems
• Drain tile connections
• Proper grading around the window well
• Drainage improvements to reduce water buildup

While no drainage system can eliminate every risk, an experienced contractor should explain your options and recommend the best solution for your home.

Make Sure Your Contractor Uses Professional Equipment

Installing an egress window involves much more than cutting a hole in a foundation.

Professional contractors should use track-mounted wall saws that are securely fastened to the concrete foundation. This allows for:

• Straight, accurate cuts
• Level window openings
• Minimal vibration
• Clean corners with little or no overcutting

Removing the concrete section safely is equally important. Foundation wall sections can weigh well over 1,000 pounds, making proper lifting equipment essential.

Experienced contractors use equipment such as:

• Cranes
• Excavators
• Skid steers
• Other specialized lifting equipment

Using the proper equipment helps protect your home, your property, and everyone on the job site.
