Most Window Hardware Problems Can Be Fixed on the First Visit

We stock the most frequently needed window parts on our service vehicles at all times — so when we show up, we're ready to fix the problem, not just diagnose it.

With the wide variety of window brands and hardware configurations across northern Illinois homes, preparation is everything. Rather than showing up empty-handed and ordering parts after the fact, we anticipate what jobs require and stock accordingly.

If we don't have a needed part on hand — whether it's rare, proprietary, or simply unusual — we'll track it down and return to complete the job within a few days. We don't leave projects unfinished or clients waiting indefinitely.

Parts & Components We Carry

Hinges — casement and awning configurations
Casement window operators & cranks
Lock assemblies & handles
Balance systems for single & double-hung windows
Tilt latches & pivot bars
Weatherstripping & perimeter seals

Speed things up: If you already know the part number, brand, or model of what's broken, share it when you contact us. The more detail you can give, the better prepared we'll be — and the more likely we'll fix it in one visit.

What You Need, When You Need It

Faulty windows aren't just an inconvenience — they affect your home's energy performance, security, and daily comfort. We take that seriously.

Common Window Repairs

Hardware Problems We Fix Every Day

From sticky casements to windows that won't stay up — these are the repairs we handle regularly across Will & Grundy County homes.

Hinges

Worn, bent, or corroded hinges cause casement and awning windows to sag, bind, or fail to seal properly. We carry a wide range of casement and awning hinges for same-visit replacement.

Casement Operators & Cranks

A stripped or broken crank operator makes your casement window impossible to open or close. We stock operators for the most common casement window brands in the region.

Lock Assemblies & Handles

Broken or worn locks compromise both security and weathertight performance. We carry replacement lock assemblies and handles for a wide range of window styles and brands.

Balance Systems

When a hung window won't stay up on its own, the balance has failed. We carry spiral, block-and-tackle, and constant force balances to restore proper operation to single and double-hung windows.

Tilt Latches & Pivot Bars

Missing or broken tilt latches prevent hung windows from tilting in for cleaning and can compromise the window's security. Quick to replace with the right parts on hand.

Weatherstripping & Seals

Drafts, noise, and moisture intrusion often trace back to failed perimeter seals. We assess and replace weatherstripping across all window types to restore a proper air and weather seal.
Have a Proprietary or Rare Part?

We'll Track It Down

Some windows — particularly older Rockwell, ROW, and Wenco units — use parts that aren't easy to find. We've been sourcing specialty hardware for discontinued window brands for years and know where to look.
Even if we don't have the exact part on the truck, we'll identify what's needed, source it, and schedule a return visit to complete the repair as quickly as possible. We don't walk away from a job unfinished.
