"I wished if it were be able for me to give this company more than 5 stars for my review. Right after I realized that we have Raccoon residence in my attic I sent an email at midnight to Attic Fanatics. I got a call at 8 from Coby who said someone will come within a hour. Mike Bruer showed up on time and did a thorough inspection. He advised me that the Raccoon may have been in my attic for awhile. I decided to replace all insulation. He provided me a reasonable quote which I accepted right at the spot. He also helped me to file a claim with my homeowner insurance company. On the very next business day there was a crew of 5 people showed up on time. They are very professional and did a neat job. Being a picky person like me I am totally satisfied of their work. They sealed the openings to prevent the Raccoon from return. After they left I found out there is one Raccoon was still in the attic so they came back right away and chased it out then resealed the soffit vents with heavy gauge mesh. Great job!"

THE START Turning Your Home Green, the insulation specialist, is a family business dedicated to making your living space a more comfortable, eco-friendly environment. My father started a residential renovation company in New Jersey 35 years ago. Over the years, almost every house he entered was inadequately insulated. He evaluated the living space and provided a solution to correct the problem.

"Gene was very responsive to my request for an evaluation of my home to find opportunities to address cold/ drafty rooms. He performed a free assessment which was nice (not all in this business do). He made several recommendations after an in depth examination, and wrote up a detailed quote breaking out each line item. I appreciated the cost transparency. We decided to take the initial step of applying spray foam to insulate the duct work in the basement and attic. Gene used good ventilation techniques and the end result was very neat. He cleaned up well. He shared the before and after data in terms of the surface temperature of the duct work. It is clear it is making a difference in terms of the evenness of the heating in the home. I will definitely hire again."

FAQs for spray foam insulation projects in Mahwah, NJ

Yes, you should remove old insulation if it's damaged, contaminated, or deteriorated. Signs like water damage, rodent droppings, mold, or gaps mean removal is essential to maintain energy efficiency and a safe living environment. If the insulation is intact and functioning well, removal isn't necessary. However, compromised insulation can increase energy costs and pose health risks.

Attic insulation lasts 80 to 100 years; however, its performance starts to decline after 15 years. Insulation loses effectiveness as materials like fiberglass become dirty, wet, or affected by mold and other contaminants. Regular evaluation is critical because reduced insulation performance leads to higher energy loss. A professional inspection confirms when replacement is necessary, ensuring that your home maintains peak energy efficiency and comfort.

Excess attic insulation does not enhance energy efficiency beyond an optimal threshold. When insulation surpasses the necessary level for your region’s climate, additional material does not improve heat retention and may cause moisture buildup. Maintaining the correct balance is essential because over-insulation can lead to unintended issues without lowering energy costs. A professional assessment ensures that the amount of insulation is ideal for performance and efficiency, and helps avoid unnecessary expenses.

R-value is the measure of a material’s ability to resist heat transfer and directly determines insulation performance. A higher R-value means the material retains heat efficiently during winter and minimizes energy loss in warmer months. Selecting insulation with the appropriate R-value for your specific location is essential because environmental conditions and installation areas significantly influence energy efficiency. Over time, external factors like moisture may degrade the R-value, which underscores the importance of periodic evaluation.

Insulation damage occurs in several forms, including mold growth, pest infestations, water intrusion, and electrical harm. Damaged insulation compromises heat retention and significantly increases energy expenses while posing serious health risks. Immediate removal and replacement of compromised insulation are imperative to restore optimal performance and ensure the safety of your home. Regular inspections will identify these issues early, allowing for swift corrective action that maintains efficiency and protects occupants.
