A window that won’t open, close, lock, or stay in position is more than a nuisance — it’s a ventilation, safety, and security issue. Atlantic Window Repair’s technicians diagnose and repair operating mechanisms on all common residential and commercial window types across South Florida.
Window Types and Their Mechanisms
Casement Windows
Casement windows are hinged on one side and operated by a hand crank. Common failure points include: worn or stripped crank operators, broken hinge arms and tracks, and failed locking mechanisms. We service and replace casement operators from Truth Hardware, Roto Frank, Andersen, Pella, and other major manufacturers.
Awning Windows
Awning windows hinge at the top and open outward using a crank or push-bar operator. Similar to casements, the operator gear is the most common failure point. We replace operators and hinge arms for all major brands.
Double-Hung Windows
Double-hung windows rely on a balance system — either spring balances, block-and-tackle balances, or spiral (tube) balances — to hold the sash in position and make it easy to raise and lower. Failed balances cause sashes to fall shut or become very difficult to operate. We diagnose and replace balances to restore smooth operation.
Sliding Windows
Sliding windows run on a track with rollers or glides. Worn rollers, bent tracks, and failed latches are the most common issues. We replace rollers, clean and realign tracks, and repair or replace locking hardware.
Single-Hung Windows
The lower sash moves; the upper is fixed. Balance replacement is the most common repair.

Frequently Asked Questions
My casement window won’t close fully — what’s wrong?
Most often this is a worn crank operator that has lost the mechanical advantage to pull the sash tight, or a hinge arm that has bent or come out of its track. Both are repairable.
My double-hung window sash falls down on its own. Can it be fixed?
Yes. This is almost always a failed balance. Depending on the window’s age and manufacturer, we either replace the balance cartridge or the entire balance assembly.
Do I need to replace the whole window if the hardware breaks?
In the vast majority of cases, no. Operators, balances, hinges, and latches can be replaced independently. Full window replacement is rarely necessary for mechanism failures.
Can you get parts for older or discontinued windows?
We maintain a wide stock of hardware and have access to aftermarket parts for most discontinued models. In some cases, we can fabricate adapter solutions when original parts are no longer available.
How long does a mechanism repair take?
Most single-window mechanism repairs take 30–90 minutes on-site. We carry common operators and balances in our vehicles for same-day repairs on most standard window types.
