How long does a typical window or door installation take in Burke?
Most single window or door replacements are completed in a day, while larger projects like a full home’s worth of windows or a multi-door exterior upgrade may take several days depending on scope. We’ll walk you through a specific timeline for your project during your free estimate.
Does Landmark handle disposal of my old windows or doors?
Yes. Removal and disposal of your old materials is included as part of every installation — you won’t be left to handle cleanup or hauling anything away.
What's the difference between window replacement and full-frame replacement?
Standard window replacement fits a new window into your existing frame, which is faster and less invasive when the frame is still in good condition. Full-frame replacement removes the old frame entirely when there’s rot, water damage, or you’re changing the window’s size. We’ll assess which your home needs during your free estimate.
