"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED .

"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

PEX pipe does not need to be insulated if passing through interior walls or insulated external walls. However, despite its resistance to cracking, you should still insulate PEX pipe in unheated areas if you experience cold winters in your local area. Otherwise, repeated freezing and thawing may weaken the pipes over time and create the risk of bursting.

Yes, products made from renewable resources and with reduced chemical impacts.

Homeowners insurance covers some damage caused by ice dams, but it depends on the type of damage. Insurance policies will often cover things like interior water damage, roof collapse, and actual shingle damage resulting from ice formation, but it depends on your policy. Check your coverage information or contact your insurer to find out what your plan covers. Keep in mind that any damage caused by implementing a DIY solution to remove ice dams likely won’t be covered.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

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.
