    Phelps, NY

    We are extremely happy with the professionalism and friendliness we experienced with Marshall Exteriors. A family member and neighbor used Marshall Exteriors and the financing options were a big benefit. The products were ordered, received, and installed within a short period of time. The installers were very careful and left our job-site neat and cleaned up. Jeremy the estimator did a nice job, and the owner Adam's follow-up and attention to details was a strong point in favor of Marshall Exteriors's company image.

    Customer Testimonial

              A storm pulled up a lot of shingles on the roof. The hail chipped the windows and siding pretty bad. Calling Marshall's exceeded her expectations from the beginning because when she called, Adam was in the area and came right over to talk to her about her home. The crew showed up promptly at 8am and were gone by 4pm. The crew did a great job cleaning up after themselves leaving no nails in the yard.

Having a 2nd story balcony and sliding glass door removed and replaced with a sliding window allowed for the installation of a new Betterliving Awning. Having crews that worked specifically on their specialty was very impressive to the homeowners. The coordination of all the work with specialty crews was perfectly timed.
