"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

2x4 walls can hold R-13 or R-15 batts of insulation, which is usually about 3.5 inches thick. You should also check with your local building codes to see if there’s a required thickness you need to adhere to. 

You can also use R-value maps to determine the best thickness and ratings for where you live. For example, someone in Texas doesn’t need as thick of insulation as someone in Montana. Energy Star has a good one you can reference.

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

Yes, many services include adding insulation for energy efficiency. Confirm with your contractor.
