Most projects are completed in just one day. Our small, experienced crews typically install 8–10 windows per day and work one opening at a time, carefully measuring each opening and window as they go. This approach minimizes disruption to your routine while ensuring precise, professional, high-quality results.
Pricing for made-to-order doors varies based on a number of factors. Door style is the most significant factor in determining front door and patio door pricing. The materials used, quality, glass package, and brand also affect the final cost.
