"The roof and trim were done, and look great. But I have a couple of issues .The crew was very unfriendly. I came out just to say hi, and they sneered at me and walked away without a word. Also, after they left I found out that they apparently cut an electric wire as I had a tripped breaker and now some of my electric baseboard heaters don't work. This was in an area where they replaced sheathing material right over my breaker box. I contacted the rep, who acknowledged my issue and I am waiting to hear back."

"I have hired Permaseal to fix my unleveled patio concrete floor that was and still causing rain water to get to my basement, I have paid them $2,014.33 as down payment, they showed up one month later for the job, which is injecting foam under the concrete slab to lift it back to its original correct level. I came back home that day to find out that they have left and that the concrete slab was not only still unleveled, but they cracked it and patched it on multiple locations. I have called their customer care number more than a dozen times in attempt to understand what is going on, and on each occasion, I was told that the project manager was going to contact me back, which never happened until i made the next call, They have finally explained to me over the phone that it was the best they could do and that they could not fix my patio floor. I asked for a refund and did not hear back. I have documented pictures of before and after showing that the job was not done and cancelled the check with the remaining balance. I have not heard anything back from them since then, until i started getting debt collectors' emails on December the 5th from a business called FCR Services."

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.
