Finished basements along the Cermak corridor
Nearly every Berwyn house has a basement and a good share of them are finished, which makes the basement the default media room along the Cermak corridor and through South Berwyn. Two walls live down there and they behave nothing alike. Interior partitions are framed with 2x4s and take lag bolts. The perimeter is drywall or paneling on 1x2 furring strips laid over foundation block or a poured foundation, and furring holds nothing on its own. Your installer drills through it and seats 1/4-inch Tapcons about 1-1/4 inches into the concrete or the face shell of the block, which is masonry work and carries the +$99 surcharge. Moisture is the other half of the job. Freeze-thaw drives water through hairline foundation cracks most springs, so the bracket and every connection sit above any past waterline, cable is CL2-rated, and the receiver goes on a shelf off the cold exterior wall. A dehumidifier held near 50% keeps the gear and the cable happy through a humid July. Berwyn basement installs run 60 to 90 minutes.
