"Gus (owner) came out to provide an estimate. He was in the attic for about a half hour looking over the space so that a complete estimate could be provided. Several weeks later Gus came out and added blown in fiberglass insulation which made the area an R-60. While Gus insulated the attic, he took pictures on his cell phone and showed me the completed work."

"I recently had Attic Pro of New Lenox, IL install blown-in insulation as an upgrade to my existing attic setup, and the results have been fantastic! My main reasons for doing this were to boost energy efficiency and cut down on those skyrocketing heating and AC bills—our old insulation just wasn’t cutting it anymore, especially with Illinois winters and humid summers. Within the first month, I’ve already noticed a huge difference: the house stays warmer in the cold without cranking the heat, and cooler in the heat. For the first time I am looking forward to seeing my next utility bills. The team at Attic Pro was top-notch from start to finish. They provided highly personalized service and paid incredible attention to detail—inspecting every nook, sealing air leaks, and ensuring the blown-in material was evenly distributed for maximum R-value. No cookie-cutter job here; they tailored everything to my needs."

"Greg, the owner, came out on two occasions to discuss the crawl space and drain tile. He is extremely knowledgeable and experienced in the crawl space industry. We had a few options and he told me about the new spray product he was using. It is this unique seamless liner that is sprayed on after preparing and insulating the area.
His crew was very professional and easy to talk to. We had some scheduling conflicts that were easy to work around and get the job done when we needed it to be finished.
The difference we noticed in the smell in our basement, the effect the insulation and seamless lining had on the air conditioning in our family room (which is above the crawl space) was immediate. We feel cooler air coming through the duct work since it isn't losing energy traveling through a non insulated space anymore and they basement smells and feels normal since the dirt and concrete is now completely covered by the new liner.
That new product is great.
Greg's company also did drain tile work in our basement. It was a different crew than the group who did the crawl space, but they were equally as professional and easy to work with. Rather than break up the job into 3-4 days they stayed late the first day to get everything ready and prepared so they could complete the job quicker. The job was done the next day. The price was very fair and the crew was extremely clean throughout thew whole process.
We now have a water tight, well insulated basement and we couldn't be happier with the results.
I have told several friends about the experience and would recommend them anytime. From Greg down to each of his crew members they really know how to do a good job and work with the customer."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Wilmington, IL

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
