Retrofit Window Installation Advantages and Disadvantages

FAQ: What Are the Advantages and Disadvantages of Retrofit Window Installation?

Q: What are the advantages of retrofit installation?

1. Cost-Effective

Retrofit installation is generally more affordable than full-frame or brick-to-brick methods, making it a popular choice for budget-conscious homeowners.

2. No Interior Work Required

The original interior casing and jamb extension (ledge) remain in place, so there’s no need to replace or repaint interior trim.

3. Shutters and Blinds Can Usually Be Reused

Most existing shutters and blinds will still fit after the installation.

Note: The depth of the window ledge must be verified to ensure the shutters can fit between the jambs without obstruction.

Q: What are the disadvantages of retrofit installation?

1. Hidden Structural Issues May Go Undetected

Because the original frame remains, any rot, mold, or water damage in the wall studs is not exposed and may go unnoticed during installation.

2. No Additional Insulation

Since the wall cavity is not opened, it’s not possible to add insulation between the window frame and the studs for improved energy efficiency.

3. Smaller Window Size

The new window fits inside the existing frame, slightly reducing the visible glass area and natural light.

4. Bulkier Exterior Look

The combination of the existing brickmould and new window frame, both wrapped in aluminum, can create a thicker and more prominent exterior profile compared to full-frame installations.
