"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!"

"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."

"I hired this company to clean the air ducts and spray for brown recluse spiders which our other pest control company had not been able to eliminate in 15 months. Healthy Home cleaned the duct work which I was very pleased with. They were neat and clean with their work, prompt and efficient. I can't say that I'm as pleased with the bug spraying. They put powder down around the baseboard in the closets. It was EVERYWHERE and so thick. I cleaned it up some but left some around the baseboards to poison the spiders. The spray in the rest of the house was all over my hardwood floors. We had gone for a very heavy treatment to get the brown recluse so I excused this. However, I just had a quarterly spraying done and I had voiced my concerns to the technician about the spray on the hardwood and asked that he be more restrained in the spraying. The spray was again on the hardwood but not quite as bad but I have spray ON my desk, the bathroom cabinets, the kitchen cabinets, my china cabinet. I have had to clean all of this off and then he also sprayed in front of the TV cabinet, the china cabinet, the buffet so the spray is all over the hardwood floor but not near the baseboard. Who sprays in front of the furniture? The brown recluse travel around the baseboard, not out in the middle of the floor. THe smell of the spray when I disturb it when cleaning it up travels throughout the entire house. VERY disappointed but I will voice my concerns to the company. So yes, I would strongly recommend them for duct work cleaning but the bug spraying is still very much in the air.. but I've only seen one brown recluse so that's good."

"A fabulous experience in workmanship, pricing, cleanup and follow-up on meeting expectations. I spoke to three companies and immediately selected the best. Call PEC We had foam, new baffles and more insulation to be R-49 rated. As new retirees, our ROI is due to increased energy cost by 25% compared usage from 2020 to 2021. With energy costs rising we have to be proactive. We made an intelligent decision"

"Estimate./proposal done by Bryan. Knowledgeable and professional. Did have to reschedule appointment due to equipment problem on a job prior to my estimate. Scheduled the work with office staff (Chris) for a couple of weeks out. Got a call the afternoon before installation that they would need to move to the next day due to having to stop an attic blow in install because of rain. Very apologetic. Bryan and Tammy arrived a bit later than scheduled due to back up at the warehouse where they were picking up the spray foam tanks. Bryan and I walked through the job and made sure we both were fully aligned on the areas to be insulated. Job went smoothly and was done professionally. He did a good job of covering under a bay window to be sure it was fully insulated. Cleaned up the area very well after they were done. They use a fully automated system to schedule and sign off on the contracts. You will need to be somewhat capable technologically through smart phone, tablet or computer."

FAQs for spray foam insulation projects in Saint-Louis, MO

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
