"Simply stated, these guys were fantastic. My wife and I have dealt with numerous contractors throughout the process of remodeling this building and Mass Energy Lab was by far the best company we've dealt with. Their prices were much less than I expected, the installation went very well, and the customer service was perhaps the best I've ever received in any purchase I've made in my life. Moreover, when problems with the building arose unexpectedly and threatened to derail the plans, Mass Energy Labs worked out a solution, performed the extra labor required and did not charge a penny more on the bill. I am a very, very happy customer." Read more testimonials.
