"Well, the was too much on the second floor but Aladdin solved that with blown insulation. I look forward to the cool savings in the summer and warm savings in the winter. The house has not added insulation since it’s manufacture in 1989. We have been here for 4 years. Should have done it four years ago. Thank you Aladdin!"

"One of the best experiences we've had with work done in our home. Zac and the team from Foam Co went above and beyond for our project - removing the old insulation from our attic and installing new insulation. They arrived exactly at the agreed on time, took care to protect our home from any mess or damage, and completed the entire project in just a few short hours. All of the team members were polite and kind. They went above and beyond to clean up at the end of the project and to make sure we were satisfied with their work. We will absolutely hire them again in the future!"

"I chose Carico Drywall because of his attention to detail, the fact he came out to give me an estimate, and the fact that he uses Union Drywall Installers. He was my 3rd bid in my buildout for my garage, and he was the highest bid by far. But the fact that he came to my house, met with me, explained and asked good genuine questions proved to me that he was the correct person to do the job. My garage is 1500sqft (30 ft deep , 50 ft wide) ceiling height is 18ft. At the peak, its roughly 22ft. I used R21 batting in the walls and 6 to 7 inches of open cell spray foam in the ceiling. The shop was drywalled with 5/16 inch drywall, no real need for anything thicker since the insulation keeps most sound dampened. I didnt tackle the drywall, because I felt like that would have taken me forever. Would i recommend Carico to do more projects? Yes I would."

Insulation questions, answered by experts

Several types of professionals handle insulation service across MO. Dedicated contractors focus strictly on installing and removing materials. Certified energy auditors assess your whole home to recommend efficiency upgrades. HVAC professionals wrap ductwork and seal attic air leaks to improve heating performance. For older brick and stone homes common in St. Louis, spray foam specialists handle irregular cavities. General contractors also manage these upgrades during larger historic home renovations.

Helpful?

In St Louis, you’ll find contractors specializing in spray foam, blown-in cellulose, and batt insulation, as well as HVAC professionals who offer energy audits and weatherization services. Some roofing contractors also handle attic insulation upgrades. Choosing a contractor with experience in older St Louis homes ensures they understand local building materials and common issues like brick construction or outdated wiring.

Helpful?

Schedule your insulation service during the mild St. Louis spring or fall to allow safe, open-window ventilation. Keep children and pets entirely out of the house during the project. Older homes contain hazardous lead paint, asbestos, or rodent droppings in attics. Professional contractors will test for these dangers and safely seal off work zones. If applying spray foam, your family must vacate the home while the materials cure.

Helpful?

For basic insulation service in St. Louis, keep a moisture meter and flashlight on hand to inspect your vapor barriers. Because the city experiences severe freeze-thaw cycles and high summer humidity, you must regularly check for shifted materials and damp spots. Keep a ruler to measure material depth to ensure your home meets local R-value requirements. Always wear a protective mask and gloves when checking attics or crawl spaces.

Helpful?

St Louis homes built before 1980, especially those with brick exteriors or located in historic neighborhoods, often lack adequate attic insulation. Signs like uneven room temperatures, persistent drafts, or high energy bills suggest your home could benefit from an energy audit and insulation upgrade. Checking insulation depth in the attic or walls is a quick way to spot if improvements are needed.
