"We badly needed insulation in our attic. We got three quotes. Weather Shield was not only the most reasonable, but the only company in which the owner both gave us the quote and installed the insulation with colleague. We could not have asked for more professionalism or better service. Would highly recommend Gus."

"We chose Attic Pro after getting a few quotes. Their representative, Ryan, was incredibly thorough. He performed a energy audit for us. The consultation was professional and informative, with clear explanations of the process and expected values. We are pleased with the work that was done by them. If you are dealing with a drafty house or high energy bills, a professional insulation upgrade is a game-changer. I highly recommend Attic Pro. Thanks again Ryan! Cesar C. "

"Green Attic did a fantastic job! They showed up when they said they would and completed the project on time. The crew was professional and friendly. The project manager shared pictures of their work throughout the day and at the end of the project. They cleaned up each day, so the home was left spotless. Big shout out to the crew that included Edison, Keiman and Ronaldo. If you’re looking for a great company to handle big or small insulation job, call Green Attic. They may not be the least expensive, but they will do the best work."

"PermaSeal is the Best. The consultant clearly explained the options for my project, the scheduling and cost. The installers were on time, explained questions I had about the basement crack sealing and Permafoam installation , completed the project in a timely manner and were friendly. This is the second project PermaSeal has completed for me. I would call them again, for sure."

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