Our Process

Installation Process

Professional, clean, and fast — see exactly how we replace your windows step by step.

90%

of Chicago area projects are insert replacements

We keep the existing window frame and interior casing, remove the old sashes, and install a new vinyl window into the opening. Outside, we finish with custom aluminum capping and color-matched caulking.

BEFORE INSTALLATION

Professional Field Measurement

After your online estimate, we schedule a field measurement to verify sizing and finalize window details before manufacturing your custom windows.

Check rough opening: width, height, squareness, sill condition, and frame stability
Confirm style & egress: proper ventilation and safety requirements where needed
Select final options: Low-E glass, Argon, warm-edge spacer, and exterior capping details
Final quote & scheduling: no pressure, no upselling, transparent pricing

Which Method Is Right?

Insert vs. Full-Frame Replacement

Most Chicago-area projects use insert (retrofit) replacement. Full-frame tear-outs are only recommended in specific cases.

Default Method

Insert (Retrofit)

Best when the existing frame is solid and rot-free.

Preserves interior casing and wall finishes
Custom exterior aluminum capping in matching color
Faster installation with minimal disruption
Lower cost than full-frame replacement
Works well for most standard replacement projects

When It's Needed

Full-Frame

Old frame completely removed; new unit installed with new jambs and trim.

Frame is rotted, warped, or water-damaged
Structural issues are present
Homeowner wants to change window size or style
Opening needs more extensive repair

Note: Full-frame projects take more time and may require additional carpentry. We recommend them only when truly necessary. In Chicagoland, most homes are well-suited for insert replacements. We'll always inspect your frames first and advise honestly.

QUALITY DETAIL

Custom Aluminum Capping

We custom-bend aluminum capping on site to protect old exterior wood and give your windows a clean, finished look. In most insert replacement projects, the existing exterior trim stays in place and is wrapped with color-matched aluminum.

It improves appearance, helps reduce maintenance, and gives the exterior a cleaner final result without replacing all surrounding trim.

Custom-Bent Made to fit on site

Weather Protection Helps protect exterior wood

Color-Matched Multiple standard colors available
