This is a referral for a window replacement performed by Kastlebridge. We could not be more pleased with the results. We live in Beacon Hill, on a very noisy road, that also has significant wind. The challenge was to replace 32 outdated windows to effectively block out traffic noise and the strong winds, while still conforming to BHAC historical commission rules. Don and Maria provided several options, and we followed their recommendation for insulated, laminated glass. The sound mitigation and thermal insulation was amazing. Don also took care of all permits and historical approvals. Despite the high quality and extreme attention to detail, the price we were quoted and paid was lower than the other bids we received. We now have beautiful windows that enhance our luxurious, historical unit, and in addition we have significantly lower energy bills, easier to control climate, and peace from outside noise.
