Juan and his crew did a fantastic job. It is not easy to find anyone at all to do soundproofing work, but Juan knew exactly what to do. It is also not easy to find someone who will call you back to meet with you, or if they meet with you, to give you an estimate. Juan showed up promptly to meet with us and gave us an estimate in a timely manner. (We never heard back from anyone else!) He and his crew are very hard working and very efficient. In one day, they managed to put up at least 80% of the drywall, and finished everything else (tape, spackle, sanding) within another few days. After they were done, he had a person come in to clean and make sure that the loft was left in good condition. The amount we paid might have been slightly higher than another drywall specialist (of course we will never be certain because we could never get anyone else to give us an estimate!), but we cannot stress enough that Juan represents peace of mind and a guarantee that customers will be happy with his work. We have already recommended him to others, so we hope he will be kept very busy!
