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.
Save thousands of dollars — sash replacement costs a fraction of full window tear-out
No interior disruption — your 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 trim profiles
20-Year Cardinal IG® Seal Warranty — backed by the same glass used in premium Andersen & Pella windows

Most contractors will tell you that parts for these windows simply don't exist. We decided years ago that wasn't good enough — so we started crafting our own sashes built to fit these original frames perfectly.
Our custom sashes are superior to the originals: better wood, better glass, better seals. Your windows get a second life that can last another 30+ years.
Damaged or deteriorating glass is a detriment to your comfort, energy efficiency, and home security. The good news: full window replacement is rarely necessary. When the sash and frame are still sound, new glass alone can transform a window's performance.
Upgrading old glass to a Cardinal Insulated Glass unit with LoE coating and Argon fill dramatically improves energy performance — often beyond what even a brand-new standard window delivers. You get better insulation, reduced glare, and lower heating and cooling bills.
When it comes to energy efficiency, durability, and long-term performance, we trust Cardinal IG® above every other brand. It's the same glass specified by Andersen, Pella, and Marvin for their premium window lines.
Cardinal IG® holds the lowest seal failure rate in the industry and the highest Argon retention rate of any manufacturer. Their Lodz-366 coating sets the benchmark for solar heat gain control — a standard others are still working to match.
With the wide variety of window brands and hardware configurations across northern Illinois homes, we've made it our practice to stock the most frequently needed window parts on our service vehicles at all times. That means faster repairs, fewer return trips, and less disruption to your day.
If we don't have a part on hand — whether it's rare, proprietary, or simply unusual — we'll track it down and be back to complete the job in just a few days. We don't leave projects hanging.
Pro tip: If you already know the part you need, let us know before we arrive. The more detail you can give us — brand, model, part number — the faster we can have the fix ready when we show up.
