Original sash, wood frames, and true divided lights can be difficult to match with modern replacement products, especially in a historic district. Once a homeowner starts changing sash profiles or opening sizes, the project can move well beyond a simple window job.

With interior storm windows, the existing window stays in place and the storm layer goes on the inside, where it is less visible from the street. If the sash operate reasonably well and the glass is intact, interior storms can extend the useful life of the entire assembly.

When Interior Storm Windows Are Better Than Replacement

What To Confirm Before Ordering Storms

• Are the frames and sash still in good enough shape to preserve?
• Do you need seasonal removal, or a more permanent installation?
• Does the design fit around the current details without trimming the house to fit the window?
• Is the installer familiar with historic homes and local approval concerns?

Why Fit And Detailing Matter So Much
