Window Well Screens – The plastic or fabric in the window wells screens is easily shredded by mice/voles/moles who fall into the window wells and try to claw their way out. Windows & Doors by Brownell can replace the damaged screens with the same plastic or fabric but if you want a more animal and weather resistant screen, Burlington Glass ( 1860 Williston Road, S. Burlington) can replace the screening with gray aluminum for about $16 a screen.
