Replacement windows have pre-drilled holes in the frame to allow easy installation into an existing outer frame. They are delivered in the exact dimensions ordered to allow a tight fit.

Mezzo Replacement Single Hung Window
Our flagship replacement vinyl window, with a fixed top sash and a bottom sash that slides up. Pre-drilled holes and precise sizing make for a tight fit into your existing outer frame, with no disturbance to the surrounding trim.
Mezzo Replacement Double Hung Window
Both sashes slide vertically and tilt inward, so you can open the top, the bottom, or both, and clean the outside of the glass from indoors. Delivered in the exact dimensions you enter for a tight fit into the existing frame.
Mezzo Replacement Sliding Window
The sash glides horizontally along a track rather than vertically, which suits openings wider than they are tall and takes no space outside the wall when open. Made to your measurements for a direct swap.
Mezzo Replacement Picture Window
A fixed unit with no sash hardware and no seal to break — the largest area of glass and the tightest air seal of any configuration. The usual pick where a view matters more than ventilation.
What are replacement windows?
Replacement windows fit into the outer frame of a window you already have, rather than into open wall framing. They have pre-drilled holes in the frame and are made to the exact dimensions you order, so the existing frame, siding and interior trim stay where they are.
What configurations are available?
Mezzo replacement windows come in Single Hung, Double Hung, Sliding and Picture/Fixed. Each is customizable in size, color, glass and grid pattern in our online configurator, with the price updating as you go.
How do I measure for replacement windows?
Measure the existing frame, not the glass, and take the width and height in three places each — the smallest of the three is the one to use. The dimensions you order are the outer dimension of the unit, so measure carefully: see our measuring guide before you order.
What is the lead time?
Mezzo replacement windows are typically ready in about 30 days after final order confirmation. See our lead time page for the latest estimates.
