Windows explained
Window work ranges from repairing a damaged sash to replacing whole units. A replacement window can go into the existing frame as an insert, or the entire window, frame and trim included, can be removed and replaced, which allows the opening to be inspected and flashed. A window only performs well when the opening around it is properly sealed and flashed, because most window leaks are installation leaks rather than glass failures. Choices include style, frame material, glazing, and finish. In co-ops, condos, and landmarked buildings, rules may limit what you can install or how it should look, so approvals come before ordering.
Options and materials
Insert replacement windows
A new window unit installed within the existing frame. Faster and less disruptive, and suitable when the frame and surround are sound.
Full-frame replacement
Remove the old window and frame, inspect and repair the opening, then flash and install a new unit. Best when there is rot or leaking.
Sash and glass repair
Repair or replace broken glass, sashes, and hardware when the window is otherwise sound and worth keeping.
Trim, sill, and sealing work
Replace rotted sills and trim and renew exterior sealing and flashing at the window to stop water entry.
Window style changes
Different styles such as double-hung, casement, or fixed can be considered where the building and approvals allow.
Our process
- Survey the windowsWe check each window's condition, frame, sill, and surrounding wall for rot or water damage, and measure each opening carefully.
- Choose style and materialsWe review styles, frame materials, and glazing options with you, along with any co-op, condo, or landmark requirements.
- Written scope and schedulingYou receive a written estimate listing units, trim, and flashing work. Custom windows have lead time, and we explain it up front.
- Remove old windows and inspectOld windows are removed carefully, and the opening is checked for rot or damage, which is repaired before the new unit goes in.
- Install, flash, and sealNew windows are set level and plumb, flashed, insulated around the frame, and sealed to shed water.
- Trim, adjust, and clean upInterior and exterior trim is finished, the windows are tested for operation, and the site is cleaned.
What affects the price
Number and size of windows
Larger windows and larger orders change material and labor, and custom sizes cost more than standard ones.
Window type and style
Double-hung, casement, bay, and specialty shapes differ in price and installation effort.
Frame material and glazing
Frame materials and glass options change the unit cost and performance.
Insert versus full-frame
Full-frame replacement with trim and flashing takes more work than an insert into a sound frame.
Hidden damage
Rotted sills, framing, or wall damage found behind old windows adds repair work.
Floor level and access
Upper-floor windows, street frontage, and limited access can require added equipment or protection.
