"FoamCo recently insulated our basement walls. Before, we couldn’t use the basement in the winter time. We noticed an immediate difference once the insulation went in, and now our basement is our favorite cozy hangout spot in the house. They were great at explaining exactly what kind of insulation I needed and were actually the best priced bid we got."

"St. Louis Insulation did a great job with insulating and ventilating both the attic and basement of our 123-year-old house in STL city. Zac was very knowledgeable and helpful and the service was affordable. The job was done quickly and efficiently. I highly recommend them for any insulation needs in the city."

"He was very knowledgeable and professional. After the audit we received an estimate to correct any areas that were discovered. Unlike what we originally thought our issues were not the windows and doors. The estimate was for $4000 to add insulation to the attic, increase airflow in the attic, install foam insulation around our fireplace and throughout the basement as well as removing the attic fan and adding drywall. 
The price is the estimated price for projects to be completed.

"The BATH UPSTAIRS   had a window that needing bracing, a bath that had black mold behind the horrible VINYL wall, and had to be insulated with MOISTURE proof materials and RE-TILED - the walls, under the window and behind the tub and around the laundry chute opening.  The Downstairs Bath also needed the window braced and tiled as it was falling and splitting from the ceiling due to POOR WORKMANSHIP by someone NOT on Angies List back in 2003!!   SO, Siding Repair Systems -  They did it all, with their contractor Thomas Morton.  What a really fantastic job - on BOTH these Bathroom windows, Tiling and securing/supporting.  EXCELLENT WORK!!  Clean and neat - it looked like they had a MAID SERVICE come in and clean up after them.  Honestly.  So neat and clean they were.  Thanks for a Really good job.   "

FAQs for insulation service projects in East Saint Louis, IL

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
