"Moshe and his team at Attic Kings are amazing! When I contacted them, they got back to me almost immediately with a date and time for an estimate to install insulation. Moshe was very communicative, texting and calling to let me know when he would arrive. On installation day, Moshe made sure to keep everything as clean as possible, and everything went incredibly well. They are all so kind--would definitely hire again!"
