Sash Replacement

Service 01 — Sash Replacement

Custom Window Sash Fabrication & Replacement in Northern Illinois

Is your window decaying, warped, or drafty? Before you spend thousands on full replacement, find out if a new sash is all you need. In most cases, it is.

A window fails most often because the sash — the movable frame holding the glass — has rotted, warped, or deteriorated. But the main frame set in your wall is usually still sound. Simply patching the rot is a temporary fix at best. Replacing the sash entirely with a new, energy-efficient unit is the smart, lasting solution.

We fabricate custom replacement sashes by hand in our climate-controlled facility in Diamond, IL. Every sash is built to fit your existing frame precisely — no shimming, no gaps, no compromises. Each comes complete with new Cardinal LoE366 insulated glass, hardware, and weatherstripping.

Why Choose Sash Replacement Over Full Replacement?

Save thousands of dollars — a fraction of the cost of full window tear-out

No interior disruption — trim, drywall, and exterior capping stay untouched

Dramatically improved energy efficiency — new LoE/Argon glass outperforms most newer windows

Preserves your home's original look — no vinyl frames or mismatched profiles

20-Year Cardinal IG® Seal Warranty — the same glass in premium Andersen & Pella windows

What Goes Into Every Sash

Built Better Than the Original

Not mass-produced. Not shipped from a warehouse. Every sash is made by hand in Diamond, IL — with materials chosen for longevity, not just lowest cost.

Accoya® & Solid Poplar Wood

Full-length solid poplar for the frame, with an Accoya® 50-year modified wood bottom rail — the most rot-prone section of any sash, solved permanently.

Cardinal LoE³-366 Glass

The highest standard in solar heat gain control — standard in every sash we build. Includes a 20-Year Seal Warranty and averages 30+ years of real-world performance.

Exterior-Grade Coated Fasteners

Corrosion-resistant fasteners throughout — the same standard used in marine applications. No shortcuts, no rust, no loosening over time.

RTV Silicone Glazing

Glass is set with RTV Silicone — a flexible, permanently bonding sealant that outlasts traditional glazing compounds by decades.

Superior Hinged Weatherstrip

Premium hinged weatherstripping on every sash — sealing out air, moisture, and noise far more effectively than factory original hardware.

Climate-Controlled Fabrication

Built inside our temperature and humidity-controlled facility in Diamond, IL — ensuring tight tolerances and consistent quality in every season.

ROW & Rockwell Windows — We Build What Others Can't

ROW and Rockwell (Barber & Ross) were premium window brands widely installed across the Joliet area and northern Illinois. Both companies are gone — but their windows live on in thousands of local homes.

Most contractors will tell you that replacement parts for these windows simply don't exist anymore. We disagreed. Years ago we started crafting our own custom sashes built to fit ROW and Rockwell frames perfectly — and today it's one of our specialties.

Our custom sashes are superior to the originals in every way: better wood species, better glass, better seals. Your windows get a second life that can last another 30+ years.
