We had soundproofing done in the basement ceiling using Roxul Safen'Sound insulation and a combination of 5/8" drywall and QuietRock drywall. Abe's workers were fast and efficient and cleaned up afterwards. We were especially impressed with the skill of the mudding and taping guys. Just the right amount of mud, which means minimal sanding and minimal dust. Abe himself was a really nice guy to deal with and was able to accommodate some last minute changes that we requested. Highly recommended.
