"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."

"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."

"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 Hartford, 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.
