"Sebastian and Team, They arrived on time and ready to work today. They removed the old insulation and trucked it away in sealed bags. The fiberglass was placed in their truck and they installed the new foam insulation. They took several pictures and send them to my wife and she was very pleased. Sebastian charged a fare price and would recommend him as a insulation Pro."

"We had a freezing bedroom in our house as well as a freezing entry way. Turns out it was above the garage with zero insulation. Mike came out and from the start understood what was creating the issue. Not only he is highly knowledgeable about home construction in general, he was an absolute pleasure to work with and hilarious! The team at Acorn was able to schedule us in 2 days before Christmas. If you were in the North East around Christmas 2022, you experienced that deep freeze that came through. If you want to know if your home was insulated right, nothing like freezing temps to show you. Acorn did a thorough and professional job and installed blown and fiberglass insulation. Our room was toasty with no indication of how cold it was outside. I cannot thank them enough!"

"My parents and I live in a old brick apartment building in Hoboken that is from the 1880s. The bathroom in our apartment had not been updated since the 1940s. We needed help ASAP. We checked out Cesar s page and wanted to hire him immediately. The reviews speak for themselves. When he came into our apartment to give us a quote we knew that this was contractor we needed to get the job done. Cesar is affordable, friendly, and very accommodating to any issues or concerns you have before starting the project. Two massive issues with our project were that my dad has spinal & walking issues, so we needed the floors clear of all tools and materials at the end of the each day so that father could walk efficiently through the apartment. The other big issue was that we only have 1 bathroom, so Cesar agreed to work with us on pulling the toilet off and on as every day finished so that we did not have to leave our building to use the toilet. Him and his crew are the best and take pride in their work so that owner is happy with the final result. We brought the bathroom down to the bare bones and rebuilt it back up. I worked with him every step of the way to make sure that he needed all materials to get the job done in the time we needed. This project was an intense remodel with some of the hardest demo and substrate materials that an old bathroom can have. He didn t think anything of it. He has veteran experience in the field and this remodel only took 3 weeks. We are very impressed with Cesar s craftsmanship and professionalism and we will be hiring him again for any future interior projects."

"We had done nothing for insulation for decades because we thought it a lost cause. Sean promptly came to do an assessment and told us exactly what we need at a more than reasonable price. They cleaned out the old installation/debris, sealed the openings, placed batt insulation where needed, performed blown insulation and put the spray foam on the rafters in one day! We are extremely happy."

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