"I submitted for insulation quote on Friday and Neil called and came Saturday for estimate. They completed the work on that following Friday, one week later! Already notice a difference in the comfort levels in areas of the house. Before there were 5-8 degree differences in certain rooms, now those rooms are only 1-2 degrees cooler than rest of house. We will be able to turn 4 space heaters throughout the house off now. Should offset the cost of install pretty quickly. Thanks Neil Umphress Construction!"

"USA Insulation came out and blew in the pink stuff up to R49. The crew arrived on time, was professional and very thorough with what they were going to do before starting, communicating during of their progress and then a 'show and tell' after the work was completed. Cleanup afterwards let my house cleaner than before they showed up and only took them around 1 1/2 - 2hrs from start to finish (for a 1425 sq ft attic). The entire process, from start to finish, exceeded my satisfaction and we will most certainly be recommending USA Insulation to our friends and family."

"This company did very careful and professional work.  As I said, it's a huge job.  They draped the rooms with plastic sheeting so that we wouldn't have too much plaster dust everywhere (some always escapes, but it was minor).  They patched all the holes that they made. My recollection is that they did the job in 2 - 3 days.  (I'm writing this review several years later).
One issue we ran into, which was not their problem, but you should consider it, is that when they started spraying in the foam, we discovered that we needed tuckpointing done, as the foam started oozing out like toothpaste in a few spots on the outside.

"I would totally recommend this company! Ariel went above and beyond for me when replacing my roof and gutters! Ariel would call me and let me know he was on the way or if he was running even 5 minutes behind. My house looks great and I will be using them again come spring to start replacing some of my windows. Thank you Ariel! Your crew was great, too."

"Extremely well. We had a wrap around deck removed from our backyard as it was becoming a habitat for skunks and other undesirable critters. Once the deck was removed, about 3' of the foundation was now exposed. We contacted Apex to install stone siding to the exposed concrete and improve the look. We were happy that they did this kind of work. Since it wasn't a full siding job, finding providers willing to do the job was very difficult. Apex stepped up and did a great job. We're very pleased with the results."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Dekalb, 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.
