Why Deer Park Homeowners Choose Us
Deer Park is a centrally located Suffolk community with affordable split-levels and ranches primarily built in the 1960s and 1970s. These homes typically have a large number of smaller windows across multiple levels, including basement hopper windows that are often overlooked during renovations. Our Deer Park whole-house replacement projects include custom-sized basement windows and spray-foam insulation around every frame opening to eliminate drafts and maximize energy savings from top to bottom.
