"Perma-Seal was out to insulate my attic this week and did an excellent job. David did a thorough inspection, explained everything, answered our questions, and even told us that we didn’t need certain work that we thought we needed. He was very honest, polite and personable, and gave us a fair quote with some options without being pushy. Luis and his crew began the work two days later. They were prompt, courteous, professional and knowledgeable. Luis explained how the project would be done and shared progress photos with me along the way. He even curtained off the area around the attic ladder to contain any waste and cleaned up everything perfectly. I would highly recommend Perma-Seal to anyone who is considering their services."

"Steve Gavin, the owner came out and provided me with a great price that was inclusive of the entire scope of the project. During our meeting he took the time to explain the process that his company uses. Once the permits were issued the crew arrived the next morning at 7:00 a.m. as promised. The crew met the deadline for a 1:30 inspection from the Village of Deerfield. They not only met the deadline but they passed the inspection without any issues to be corrected. The crew worked until 7:00 p.m. completing the job. I would also note that they left my home spotless!"

"First of all, we are happy with the finished product of our master bathroom and walk-in closet. We are NOT happy with the owner of this business and his handling of our project. Jeff took time to design our space over several meetings. He promised that he would be available to choose tile/granite/light fixtures/plumbing fixtures whenever we needed him. Timeline was discussed with a 6 week from contract start and a project time of 3 weeks. Permit submission was done by myself with plans drawn by Jeff. We failed the permit process with 14 items that were not addressed due to insufficient drawings. Additional time/effort was required by Jeff and us to meet the requirements to meet code, which pushed our project back several weeks. We also paid more for the project due to Jeff needing to insure his workers for our village (a cost he should have known upfront). With new drawings, we re-submitted and were approved for work to begin. I can't say enough about the FANTASTIC workers that Jeff has on his team. They were courteous and did excellent work and even suggested design modifications that made sense. One of our first tasks was to pick out a granite surface. Jeff gave us the name of a granite place and that he'd meet us there. He NEVER showed. We picked granite on our own that day. We ordered tile - on our own. We chose lighting, plumbing, fixtures, and paint colors - on our own. The next time and ONLY time we saw Jeff for the duration of the project was when he delivered the vanity and asked for money (same visit). The total project ended up taking over three months to complete. Due to various project modifications/additions, we had no idea what our final invoice would be. We waited and waited for some type of final figure. 8 months after the project was completed we finally received a remaining balance invoice for over $11,000. We were shocked to receive this invoice so far after the project was completed. Jeff explained that COVID and not having an office manager were reasons behind us not getting an invoice before then and that we fell between the cracks. While we don't argue the price, we did not appreciate the length of time it took him to get the job done, nor the amount of time before we received a final invoice. When we offered to pay $2,000 each month for the next six months we were sent a very threatening email offering us three options for payment in full NOW. Suddenly this money is due NOW when he has carried this receivable for 8 months already? We will NEVER recommend Artistic Kitchen Concepts (Jeff) to anyone in the future. His involvement in the project started out well, but dropped off to the point where we never saw him, had no further input from him, and didn't receive an invoice until 8 months after the project was completed."

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.
