Basement Safety & Code Compliance
What Is an Egress Window?
An egress window is an emergency escape and rescue opening for finished basements and below-grade bedrooms. It gives your family a safe way out and gives first responders a clear way in during a fire or emergency.

As an Andersen-certified contractor with more than 20 years of experience, we handle code review, permits, excavation, window well installation, waterproofing, and inspection coordination.

Code Requirements
New Jersey Egress Window Requirements
Local requirements vary by municipality, but New Jersey generally follows IRC Section R310 for emergency escape and rescue openings.
Our Process
Our Egress Window Installation Process
Site Review
We evaluate the basement layout, foundation, soil conditions, drainage needs, and code requirements before recommending a window size and location.
Permits
Our team handles permit applications and coordinates inspections so the project is documented correctly from the start.
Installation
We excavate 3-4 feet below grade, cut the foundation opening, install the egress window and well system, waterproof the opening, and finish the interior and exterior details. The well extends at least 36 inches beyond the window per IRC R310 for safe escape and rescue access.
Final Check
Every installation is reviewed for operation, drainage, safe access, and inspection readiness before we consider the job complete.
Window Well Options
Egress Window Well Options
Choosing the right window well protects your egress window, keeps debris out, and provides safe access. Here are the most common options for South Jersey homes.
Metal Wells
Galvanized steel or aluminum corrugated wells are the most common and cost-effective option. They are durable, lightweight, and available in standard sizes. Metal wells work well for most residential egress installations and can be painted to match the exterior.
Concrete Wells
Poured or precast concrete wells provide maximum strength and a built-in, permanent appearance. They resist corrosion, impact, and soil pressure better than metal or polymer options. Concrete wells are ideal for deeper installations and heavy soil conditions common in parts of South Jersey.
Polymer Wells
High-density polyethylene (HDPE) or fiberglass wells resist rust, corrosion, and cracking. They are lightweight and often feature a textured stone or brick finish for a more decorative appearance. Polymer wells require less maintenance over time and are a popular choice for finished basement spaces.
Well Covers & Drainage
All window wells should include a properly fitted cover to prevent falls, keep out debris and pests, and protect the well from water accumulation. Drainage gravel or perforated pipe at the base of the well directs groundwater away from the foundation. Cosello Construction includes well covers and drainage as part of every egress window installation.
Pricing Factors
How Much Does Egress Window Installation Cost?
Egress window installation cost depends on foundation type, excavation depth, drainage, window size, well configuration, and local permit requirements. For most standard basement projects in South Jersey, homeowners can expect costs in the $2,500 to $5,000 range. Complex installations involving reinforced concrete cutting, deep excavation, extensive drainage work, or custom window wells typically range from $5,000 to $8,000 or more.
Cosello Construction provides free estimates so homeowners can price the work accurately before starting. Standard projects can often be completed in one day, while deep excavation, complex drainage, or structural conditions may extend work to 1 to 2 days.
Because excavation, permits, and waterproofing can affect total cost, homeowners can review window replacement financing while nonprofit or security-focused projects can also review available window and door improvement grants.
