"I recently hired Sebastian and his company to install new fiberglass insulation and Densepack in my attic. I found them to be extremely professional. They did the work as quoted, cleaned up after they were done and took all the trash away. I would highly recommend them."

"This was a wonderful experience. We had a price range of around $3,000, and we got quotes from several places. All of them seemed very ho-hum about everything; no personal touches or even pleasant exchanges. Master Attic, however, had great customer service from start to finish. The pricing was competitive, the communication was excellent, and the workers were beyond professional. I'd recommend them to anyone needing extermination or pest control services. Thank you, everyone at Master Attic!"

"Acorn did a great job insulating my home. John explained the entire process and highlighted all the areas of focus. The crew arrived when they said and were very thorough and respectful. There was alot of dust, which was expected and his team covered as much as they could to help with the clean up. It's been over a week now and I have been monitoring heat usage thru Nest. There is a clear difference in the number of hours a day the furnace is on. I highly recommend John and the Acorn team for insulation work."

"I highly recommend this company for any type of insulation work. The salesman gave a very thorough presentation on all the available options for me, along with a rough estimate at the end of the meeting. I went with the option of removing & installing new rolled insulation (R30). The crew arrived on the scheduled installation date and got right to work. Sealed off everything properly, removed the old insulation, cleaned & cleared out the space, and then installed the new insulation. It was all completed in about 4 hours. I was very impressed."

"WE hired this company from this site. They are very dependable, hardworking people. Our office is located in CT 3 hours away from the work project. We had to hire someone we could depend on doing the job right. WE had to have them do some painting, installing new doors, repairing minor things. I would recommend this company to anyone . Excellent communication, knowledgable about construction. He also repaired a roof leak in another apartment of ours."

"They did an excellent job. They did spray foam insulation on the underside of our attic roof, as well as removal of old batt insulation in attic floor. Sean and Liron arrived on time, were professional and friendly, and installed the products promised. We would recommend this company to friends or family if they were looking for similar work."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Denville, NJ

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.
