"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 . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

"Anthony Nastasi, hired by me to rebuild our decaying bay window, did a terrific job. When he came out to survey our prospective job, he listened closely to what we wanted, took notes, did measurements, and made suggestions. Later that day he sent my a proposal, detailing the materials and total cost of the project. Ultimately, the final cost was only about $300 more as additional material was needed. Mr. Nastasi worked a full day each day he was here. He also was honest and direct - he told me when he would arrive in morning, and he did. He told me when he had to complete another job so he might have to leave early or miss a day. Many Subs aren't professional enough to simply tell the truth. He always did. I am extremely happy with the quality of the work he did, the time frame in which he completed the job and, most importantly, how it looks. I would unequivocally recommend Anthony Nastasi to anyone. John Loughrey"

"Score Construction completed a clean tile installation for me for a reasonable price. They took care of all the extras such as old tile disposal and also did some painting to to complete the job. I am very happy with the work performed. The easiest that I've found to communicate with throughout the job and a clear payment accountability system."

"Armor Insulation and More was timely, courteous, and efficient throughout the entire process. The owner went out of his way to make sure that I understood exactly the services I was to be receiving, and his team was nothing but respectful and left the house as clean as it was when they arrived. I would feel more than comfortable recommending them to family and friends."

Insulation questions, answered by experts

Yes, guiding choices between open-cell and closed-cell foams based on needs.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

Winterizing your outdoor plumbing keeps your outdoor spigot from freezing and potentially bursting. This includes draining residual water out of the pipe and spigot after turning the valve off, then removing garden hoses and other attachments from the spigot before winter comes. Insulating the pipe that leads to the spigot and installing a freeze-proof faucet also help, as does installing an outdoor faucet protector.
