Sentry Exteriors installs seamless eavestroughs with hidden hangers. Our seamless eavestroughs come with a 20 year to lifetime warranty. Each eavestrough piece is measured and made on site to fit your home. Seamless eavestrough in a continuous run means no leaking, and we guarantee it! Sentry also uses a hidden hanger fastening system, not the traditional spikes. This installation method means the eavestrough is held to the fascia board with a screw which holds much tighter, and you will see no nails on the front of the eavestrough. We offer downspouts in various shapes and sizes to match our eavestrough systems.
