“Last winter’s snows caused 40 feet of gutter & soffit & fascia to be ripped off the roof. After several problems with other contractors, I contacted The Sullivan Company (TSC) What an improvement. They set a date promptly, quickly gave me a fair estimate (which was approved by the insurance company), and set a date to begin the work. They arrived on time and completed on time, leaving the site completely clean.”
I’m really happy with the work done. Communication was always prompt and clear. The quality of the craftsmanship was excellent, and the final result exceeded my expectations. On top of that, they were courteous and friendly, making it a truly positive experience. I’d definitely recommend their services!
Got the job done as requested and for a fair price. Would hire again.
