BILCO® Basement Doors · Sizes B, C, O & SL
Classic Series Basement Doors
Give your basement its own outside entrance. The BILCO Classic Series makes it easy to move furniture, storage and equipment in and out, and helps you add code-compliant living space to your home — professionally installed by DFS In-Home Services.
Direct Basement Access
Get the Full Use of Your Basement
A wide-opening BILCO door turns a hard-to-reach basement into space you can actually use. Bulky items — game tables and furniture for a finished room, or patio sets and pool supplies for storage — pass straight through without a struggle down the interior stairs.
Choose a primer finish ready to be painted to match your home, or upgrade to a factory-applied powder coat in one of six colors. Either way, our crew handles the measuring, installation and clean-up.

Optional Upgrade
Powder Coat Paint Finish
This factory-applied polyester resin coating is tougher and far more scratch-resistant than conventional paint — and because it arrives finished, there’s no painting required after installation.
Powder coat is offered on Sizes B and C in six standard colors chosen to complement any home. Powder-coated doors can also be supplied with a keyed lock kit and pre-punched holes for a cleaner installation.
Finish warranty: one year against flaking, peeling or blistering under normal conditions. Damage from installation, falling objects, scratching, abrasion or misuse is not covered.
Primer finish: doors with the standard primer finish need a finish coat of paint after installation.
Building Code
Meets IRC Emergency Egress Requirements
Section R310 of the International Residential Code applies to one- and two-family homes. It calls for a second way out of any basement living space, so the people inside can escape if the main stairway is blocked during a fire, and so firefighters have direct access to the basement.
BILCO basement doors meet these emergency escape and rescue requirements for finished basements. The IRC is revised every three years and each state adopts it on its own schedule, so check with your local building department for the version enforced where you live — or ask us during your free in-home consultation.
