"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!"

"I had the pleasure of working with Abdias Montalvo from AMC Interior Contracting Corp. recently, in order to repair an ornate plaster ceiling that had partially collapsed. The ceiling was original to my over 100 year-old Brooklyn brownstone and I was careful to contract the work to someone who would do the work right and try to maintain as much of the original character. Needless to say, Abdias delivered by providing guidance on how best to maintain the integrity of the ceiling, without compromising too much of the original detail. He guided me through the process, always communicated openly, and respected my opinion. The final product is a testament to Abdias' craftsmanship. He is someone who takes pride in doing quality work and making his clients happy. I would highly recommend AMC Interior Contracting Corp. as an honest, reliable, and brilliantly qualified contractor."

Insulation questions, answered by experts

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.

No, you shouldn’t wrap a towel, old T-shirt, or other porous fabric around your faucets. These materials absorb water, which can make your faucet more likely to freeze. Instead, you want to use waterproof, insulative covers that can seal tightly around the spigots for the best protection against frozen outdoor faucets and pipes.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.
