What our customers are saying
About our services and us
Leonard A. Weiss2024-04-11 Suffolk Weatherization did a great job insulating my 1908 home, from both the exterior and interior. The work party (Rob and Steve) was respectful of the property, minimizing the disruption and mess, while maximizing the effectiveness of the effort. They kept me in the loop for the entire process, making on-site recommendations that were not included in the initial specs by MassSave. Omar Sacirbey2024-03-09 Great experience. Pedro and Ramone were thorough and knew their stuff so we got a great insulation job. We felt the difference in terms of warmth in our house immediately. In addition, they were very professional, courteous, and flexible. Manny Isehenrien2024-02-14 Suffolk Weatherization did an amazing job, the crew of Pedro & his Co-part was very professional. Did the job in a timely manner as stated, respected my living area, very communicative and friendly. I will definitely recommend them. Kimberly Foley2024-02-13 This company is terrific. The team who came to my house couldn’t have been nicer. Spencer and Ulysses politely and patiently indulged my curious nature by answering my many questions about the weatherization process and the equipment they were using. Besides doing a great job installing the attic insulation and weathering the doors etc., they did a great job cleaning up too! I highly recommend Suffolk for your weatherization needs. Robert Larkin2023-12-24 I highly recommend Suffolk Weatherization. The owner, Rob, and his team are excellent. They did a thorough job. Bridget Cooney2023-12-08 I highly recommend Suffolk Weatherization. The owner, Rob, and his team are excellent. They did a thorough job weatherizing my home and the temperature difference is quite dramatic. I am now semi-looking forward to the cold winter months ahead. This company is MassSave certified, and so they understand the program requirements and how to navigate that process. Big thanks to Suffolk Weatherization for a seamless experience and excellent work quality. Highly recommend. John Lally2023-11-17 P Bare2023-11-08 Rob's crew were great. No more drafts, sitting here with no heat on (43 degrees out) and not freezing! Thank you! Oliver Herman2023-09-24 The guys at Suffolk were incredibly helpful in being flexible with our schedules and getting the work done with high quality. Would definitely recommend Rob and team to anyone looking to get insulation work done (they fixed our bathroom fan as well, which was nice). Tom Ciulla2023-03-29 Insulated all my walls. They were very professional and courteous. I was happy they cleaned everything up when they were done and covered all my rooms in plastic to keep the dust down. Rob, Ulysses, Ramon, and Pedro are first class. Thank you. I highly recommend them.
