Stage 1: Assess Your Foundation and Window Placement

Before bringing in the heavy machinery you need to verify exactly where the new window will sit on your foundation wall. Planning the location carefully prevents hitting buried utility lines or compromising the structural integrity of the house.

• Utility Locates: Call the local municipality to mark all underground gas electrical and water lines before anyone puts a shovel in the dirt.

• Interior Layout: Check the basement ceiling clearances and ductwork to ensure the proposed window location works with your future bedroom floor plan.

• Drainage Evaluation: Inspect the grade of the yard to ensure the new window well will not act as a catch basin for heavy rain runoff.

Stage 2: Schedule the Excavation Team

Booking your concrete cutters and excavation crew in the late fall requires acting fast before their schedules fill up with emergency winter repairs. Getting the dirt out now saves you from paying massive winter heating surcharges for concrete work.

• Machine Access: Clear the side yard of patio furniture and debris so the compact excavator can safely reach the foundation wall.

• Dirt Removal: Decide whether the excavated soil will be hauled away in a bin or graded out over the rest of the backyard.

• Concrete Cutting: Hire a specialized team to cut the foundation cleanly which prevents structural cracking and leaves a perfect opening for the new window frame.

Stage 3: Protect the Site Before Frost Sets In

Once the hole is dug and the window is installed the exterior well must be secured properly. Leaving an open pit in the winter invites frost heave and serious water damage to your foundation.

► Backfilling the window well with proper drainage gravel immediately after excavation is the only way to prevent winter rainwater from freezing and cracking the foundation glass.

• Install the Well Liner: Secure a galvanized steel or heavy duty plastic well liner to the foundation to hold back the surrounding dirt.

• Add the Gravel Base: Fill the bottom of the well with at least a foot of clear crushed stone to allow water to drain down to the weeping tile system.

• Mount a Clear Cover: Attach a sloped polycarbonate window well cover to keep heavy snow and freezing rain out of the egress pit all winter long.

Frequently Asked Questions

Do I need an egress window for a basement bedroom?

Yes you absolutely need an egress window for any basement room designated as a bedroom. Building codes mandate this safety feature to ensure occupants have a direct escape route during a fire and to give heavily geared firefighters a way to enter the structure quickly.

How deep does a window well need to be for egress?

An egress window well must be deep and wide enough to allow a person to climb out safely. The well must provide a minimum clearance of thirty six inches projecting away from the window and if the well is deeper than forty four inches it must include a permanently attached ladder or steps.

Can you dig a basement egress window in winter?

You can technically dig a basement egress window in the winter but it is significantly more difficult and expensive. The crew must use specialized frost rippers or ground thawing blankets to break through the frozen soil which adds major labor costs and delays to your basement finishing budget.
