FAQ

Our experienced estimators will work with you to explore and recommend products that will not only showcase your home’s beauty, but make it the place you want to show off.
With a multitude of factors that contribute to the overall price of the project, such as the number if windows and doors, and materials selected, arriving at a generic cost is not accurate. Our sales team will help you narrow down options, and get exact measurements using state of the art software to get you the most accurate pricing possible.
Scope of work and quantity of windows and/or doors to be installed vary greatly between projects. We will give you realistic expectations on installation times and schedules keeping you in the loop on any changes that might arise.
We don’t want to disturb your normal routine. We will provide a Realtor type key box at the start of the project that allows us to access your home as needed.
Most of the product lines we offer from doors to windows have lifetime warranties on the material, and then we add on our 10 year workmanship warranty giving you not only a quality end result but the associated service to back it up.
