"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"Everything was fine until I got the final bill. The estimate they gave was different and the final bill was different. They had put extra charges. When I called them about it, they didn't back down. They also said that because of the extra insulation they used they did they couldn't reduce the cost. Other than that, the job was done fine. At one point, the insulation had blown in, they had a little problem, but that was worked out."

"Contacted a few different companies and had two come out to inspect a large crack in the foundation. First company came out and indicated that the foundation had failed and needed piers put in to stablize the foundation. Crawlspace Solutions came in and indicated that they felt there was nothing failing with the foundation and that they could inject the cracks and warranty the work regardless of if there was a larger issue that required piers. Scott was the person that estimated and completed the work. He was extremely responsive and did a very good job of injecting the cracks. When Scott came to quote the work he also offered a price to apply spray foam to the walls and the sill to replace the fiberglass insulation that the previous owner of the house had on the crawlspace walls. Price included in review was to inject 2 cracks and apply the spray foam. Really glad we had the foam insulation put in. Way cleaner, durable and sealed up some areas that the other insulation could not take care of. Scott also spent extra time explaining some other areas to keep an eye out on to help ensure the foundation area is well managed from any further potential issues like down spout discharge locations, hose connections and just general drainage of the property. One of the concerns we had was if we spend all this money on the injection and the foundation ends up needing to have piers put in, how would that impact the warranty. Scott assured us that if any additional settling occurs and the repair fails, they would come back and repair the injected cracks after the foundation was stable."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

FAQs for insulation service projects in Mendota, 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.
