Great service and attention to detail! We had 2 days of work including spray-in insulation, foam board, and fiberglass. McMahon planned the work well, communicated the project plans well, arrived on time and did all the work on time. They used drop cloths and booties to keep the area clean and cleaned up well at the end of each day. Very happy with the results and would definitely use McMahon again.

Mike McMahon and his team are the best! These guys totally buttoned up my 115 year old house – which when they started pretty much had no insulation in it – and they figured out how to tackle several unique intricacies and nuances that presented them with some unusual insulation installation challenges. Of equal importance, they were instrumental in helping me maximize my cost savings opportunity with Mass Saves – which in my case proved to not be straight forward, and required extra effort and attention on their part to substantiate and minimize my out of pocket costs. Something Mike was more than willing to take on and push through for us. Thanks Mike to you and your team – you guys are awesome!!
