Clearer views. Brighter spaces.
Most glass companies focus on the glass. Window hardware — the cranks, operators, balances, locks, hinges, and rollers that make a window function — is a specialty that requires access to manufacturer parts channels that aren't available at a hardware store.
KKC Glass is an authorized service provider for 12 window manufacturers. That means we have access to genuine OEM hardware and parts for PlyGem, Lincoln, Atrium, Silver Line, Sierra Pacific, Simonton, Windsor, Harvey, American Craftsman, Cascade Windows, Northstar Windows, and Prime Window Systems — the brands installed in hundreds of thousands of homes throughout the Charlotte area.
When the hardware on your window fails, the window often can't close properly — which means the seal is broken regardless of how good the glass is. A failed crank, a worn balance, or a broken lock isn't just an inconvenience. It's a gap in your home's weatherproofing and security.
The crank mechanism that opens and closes casement windows. When the operator fails, the window won't open fully or at all. We source OEM operators for all 12 authorized brands.

The balance system that holds double-hung sashes in position when open. Failed balances cause sashes to fall or resist movement. We replace spiral, block-and-tackle, and constant-force balance types.

Window locks that no longer engage, turn, or secure properly. A failed lock is a security and weathersealing issue — the sash may not compress against the weatherstripping when unlocked.

Genuine parts. Authorized warranty service.
Older windows — particularly those manufactured in the 1990s and early 2000s — often need parts that are no longer stocked at retail. Hardware stores don't carry manufacturer-specific window hardware.
KKC Glass's 27-year presence in the market and our authorized manufacturer relationships give us access to parts channels and supplier networks that most companies don't have. We can frequently source components for older windows from our 12 authorized brands that are genuinely difficult to find elsewhere.
If you've been told the part for your window doesn't exist anymore — contact us before you accept that as a final answer. Tell us the window brand, model, and what's broken. We'll find out what's available.
