Window Wellness: A yearly scheduled maintenance program

We have found over the years that a scheduled maintenance program can add years to the life of most windows. All of those "maintenance free" windows still need a regular cleaning and lubrication of all moving/sliding parts. We can also spot problems before they become headaches. Upon examination, we will identify parts that need repair or replacement. Tilt latches, balancers, glazing beads, operators, shoes, locks and keepers, rollers, weatherstripping and everything in between.


When a window is maintenance free it means no painting. The rest of the window, like anything else, needs care to operate at peak performance. Talk to a representative today about our Window Wellness Program © and experience the difference routine maintenance will make to your windows. Below are some samples of the 1000's of parts on windows that need repair or replacement.


Continue to learn about windows, their parts and what you can do to lengthen the life of  the windows you already own.

Window Parts


Rollers are located on sliding windows and doors to keep it in the track and make movement smooth. They come in single and double wheel models.

The wheels often lock up due to lack of cleaning and lubrication. A wellness service can restore locked rollers. Poorly adjusted rollers can also cause misalignment of the door, resulting in a poor seal.


Shoes are located in the track of single hung or double hung window, and connects the sash's pivot pin to the balancing system. The pivot pin fits in the cam; the black circle at its base.

The track the shoe sits in needs lubrication and cleaning to reduce friction and corrosion. The shoe can deteriorate and break after years without maintenance which releases your balancer from holding the weight of the window. 

Pivot Pins

Pivot Pins are located on the bottom of a single hung or double hung window. They fit into the cam of the Shoe to connect the Sash to the balancing system

Low-quality pivot pins are often made of composite "pot-metal" and become brittle over time. They break and the window is no longer held up by the balancing system.


Balancers are located in the tracks of single and double hung windows. They hook on to the Shoe to connect to the Sash and add tension to keep the window open when you open it. Balancers come in varying types and strengths corresponding to the weight and model of the window.

The balancers need regular lubrication and use, otherwise they will dysfunction from corrosion. When one or all of the balancers break, the force holding the window up stops and the window will not stay up. Corroded balancers will also make opening the window difficult.

If a balancer has an inappropriate tension for the weight of the sash, the window will either want to stay open from too much tension, or fall shut from too little. Sometimes, a tension adjustment can remedy this if it is the correct, functional balancer, but installed improperly.

Tilt Latches

Tilt Latches are located on top of a single hung or double hung window. It holds the sash into the window and allows the open window to be tilted in when disengaged for cleaning, maintenance or sash removal.

Tilt Latches are often made of plastic and can become brittle over time. A set of broken tilt latches can result in your window falling in when opened and can result in personal injury and/or damage to the sash or property.


Operators are located at the bottom of windows like casements and awnings. They have a cranking system that operates a set of arms that screwed to the sill that push a set of arms attached to the sash as it slides on plastic shoes in two attached tracks. Casements have an Upper Component with arms and a track and a Lower Component with arms, a track and a crank

Operators need regular cleaning, lubrication and use, or they will corrode and stop working. The window will become difficult to open and close. Wood window sills can also rot and cause the screws to back out of the plate holding the sash in. If the worm gear is broken, the crank will turn, but the sash won't move.

IMPORTANT! When closing a casement or awning window: once the sash stops moving, stop cranking. Use the locks to finish closing the window. Cranking harder does not close it tighter; it damages the worm gear. The locks and weatherstripping create the seal.

Locks and Keepers

Locks are located on the top or side of a window. They secure the sash to the window by hooking to a keeper. Some locks attach right to the sash, and others--like casements--are built into the window and hook onto the keeper on the sash.

Locks need lubrication and regular use. They can break if the window is neglected or improperly locked. When your window cannot lock, the windows can degrade; casement windows do not properly seal and vinyl windows will warp on sunny parts of the building.

We recommend you lock your windows when not using them to avoid future issues with the sash. Leaving a warped vinyl window locked can also warp the frame towards its original shape over time.

Handles allow you to operate your window. They can be attached to the bottom rail of a single hung sash, a crank for a casement operator, or a handle for a sliding door. They can come in many varieties and patio door handles often come with locks.

Handles need to be tightened and checked. Any internal lock needs lubrication should be checked for alignment. They typically break when a window is not maintained and requires excessive force to move. Cleaning and lubricating the window's moving parts will put less stress on the handle.
