What Bilco Doors Can We Install?

Steel Basement Doors

These feature:

• Rugged steel construction with a weather-resistant powder-coated or primed finish
• Gas spring lift assistance for smooth, one-handed operation
• Multiple size options 
• Emergency egress capability

Correct sizing for steel basement doors depends on the existing basement opening and foundation configuration. Frame alignment, fastening, flashing, and caulking also need to be evaluated because an exterior finish doesn’t replace proper installation and weather sealing. As your door installer,  will handle all of this. 

Polyethylene Basement Doors

These feature:

• High-density polyethylene construction that resists rust and rot and does not require painting
• A simulated wood texture in a driftwood color
• Optional side-panel inserts for light or ventilation

Polyethylene basement doors can suit homeowners who don't want to deal with extra exterior maintenance. Side-panel options should be considered alongside the opening layout and the amount of light or ventilation desired for the basement access area.

Sloped Wall Basement Doors

Designed for homes with sloped sidewalls, Bilco's sloped wall basement doors provide secure, weather-resistant access to the basement. The appropriate configuration depends on the foundation profile and the shape of the existing areaway.

Important features include:

• Easy Operation: Gas spring lift assistance allows smooth, one-handed opening and closing.
• Weather Protection: The sloped design sheds water, snow, and debris away from the door surface.
• Heavy-Duty Steel: Concealed hinges and rugged steel construction support dependable operation.
• Custom Finishes: Multiple powder-coated colors coordinate with different home exteriors.
• Secure Access: Internal mounting flanges and slide-bolt locks support exterior security.

Cellar Door Accessories

Available accessories include:

• Keyed lock kits for exterior security.
• Weatherstrip kits to help block drafts, dirt, and pests.
• Stair stringers for basement access.
• Foundation plates for a clean foundation connection.

Accessory compatibility varies by installed door model and opening conditions. Lock kits, weatherstripping, stair components, and foundation plates should be selected as part of the complete installation plan rather than treated as interchangeable additions.

Egress Window Well Systems

Bilco manufactures two distinct egress window well systems for finished basements, remodeling projects, and new construction. Suitability depends on the window’s clear opening, well dimensions, access features, foundation connection, drainage, surrounding grade, and applicable building requirements.

StakWEL® Emergency Egress Window Wells

Standard features and benefits include:

• Safety: A built-in ladder provides an emergency access route when the complete installation meets applicable egress requirements.
• Inviting Design: The system allows natural daylight and ventilation into lower-level living areas, while its earth-tone color complements many basement interiors.
• Durable Materials: Maintenance-free components resist rust and rot.
• Modular Assembly: Modules slide together to create the window well height required for the foundation.
• Foundation Attachment: Mounting flanges are designed for direct attachment to the foundation wall.

ScapeWEL Egress System

ScapeWEL features include:

• Egress Access: The system can support emergency egress when its dimensions and complete installation meet applicable requirements.
• Terraced Step Design: Terraced steps provide an access route and can also hold flowers or greenery.
• Durable Construction: Maintenance-free, high-density polyethylene resists rust and rot.
• Natural Daylight and Ventilation: The open design brings daylight and ventilation into lower-level living spaces.
• Modular Installation: Snap-together components are designed to simplify system assembly.

Castle Windows Stair System Options

Basement stair planning should begin with the selected door model, foundation opening, available areaway depth, and the items that need to pass through the entrance.

Basement Door Stair Stringers

Stair stringer options include:

• Purpose-Built Components: Galvanized steel stair stringers are designed to fit compatible basement door models.
• Heavy-Duty Construction: Each stringer uses 14-gauge galvanized steel.
• Removable Treads: Removable treads create additional room for moving furnaces, freezers, pool tables, televisions, and other bulky items.
• Multiple Sizes: Options range from 3 to 8 treads, with listed compatibility for E, SL, O, B, and C door sizes.

Stringer length alone doesn’t determine fit. The stair layout should account for rise, run, landing conditions, areaway depth, door clearance, and foundation geometry before installation begins.
