Window sashes are a vital part of your window system, ensuring smooth operation and proper insulation. Over time, sashes can wear out, warp, or rot due to exposure to weather, leading to energy loss and difficulty in opening and closing the window.

Sash replacement can resolve these issues without the need to replace the entire window, which is much cheaper. We specialize in custom sash replacements that fit seamlessly with your existing windows, maintaining both their aesthetic and functionality. This not only improves insulation and saves money, but also extends the window’s lifespan.

What You Need to Know About Sash Replacement
1
Regular maintenance and inspections can extend the life of your windows, and sash replacement is a key part of that process. In most cases, this procedure is quick and non-invasive, with minimal disruption to your home.
2
Sash replacement is often more cost-effective than replacing the entire window, especially if the frame is still in good condition. It can drastically improve insulation, reducing drafts and lowering energy bills.
3
New sashes can also enhance the overall security of your windows. Common signs that a sash needs attention include a significant amount of rotten wood, difficulty in operation, or broken glass. If you have older windows, updating the sash can maintain their historic appearance while improving functionality.
