Finish your Glendale Heights basement so it heats and cools like the rest of the house, with the water handled and the permit pulled before the walls close.
We begin with a moisture check and take care of any drainage or sump work before a single wall gets covered. Framing goes up on treated bottom plates, with room left around the furnace and water heater for service and combustion air. The outside walls get insulated, the electrical gets roughed in, and so does plumbing for a bath or wet bar if you want one. Drywall, ceilings, flooring, doors, trim and paint finish the job, plus a code egress window if a bedroom is planned.
Glendale Heights is on our regular route, and the crew reaches it on North Avenue, Bloomingdale Road, Glen Ellyn Road and Army Trail Road. The village sits in DuPage County with Glen Ellyn, Carol Stream and Bloomingdale around it. If your basement only has a couple of heat registers off the main trunk and no return, a finished room down there will run cold in winter and stuffy in summer. We plan added supply and return runs before the ceiling closes, so that work happens while everything is still open.

Seepage, sump and drainage get checked and fixed before framing starts.
The mechanical area keeps its service clearance and the combustion air the furnace and water heater need.
Supply and return runs get planned while the ceiling is open, so the finished rooms stay comfortable.
Basement-rated insulation over the concrete and treated bottom plates under every wall.
Circuits, lighting and outlets to code, plus drain and water lines for a bath or bar.
Drywall, ceilings, flooring, doors, trim and paint, and an egress window for any bedroom.
We visit, check the basement for water and look at how the furnace and ductwork are laid out before we write the estimate. The scope is free and in writing, and changes or hidden conditions get a written price you approve before the work happens. Our crew pulls the permit where the village requires it, and the job follows the inspection order from rough-in to final. The last step is a room-by-room walkthrough with you.
