DIY Tips for Vinyl Casement Windows Repairs

vinyl casement window

Every new building when constructed, come with Vinyl Casement Windows mostly for their high insulating properties, energy efficiency, and for directing the fresh air into the room.

Generally, they have detachable trims and hardware making it easy-to-repair in comparison to the other windows, even though there are many different types of vinyl casement windows.

Here are few of the commonly faced problems with Vinyl Casement Windows and few vinyl casement windows repairs (and home remedy) tips:

#Peripheral Damage to the Window Sash

Peripheral damage to the sash is one of the common casement window problems. There could be any kind of peripheral damage to the sash like a split, or flaking out. First, unbolt the arm from the inner hinge and all the other attached screws.

The sash would tilt towards you. After you unfasten the bottom screws of the bracket, remove the stop. Now you can slide out the sash and replace it. You can also change the stop, if it is broken.

When you buy a replacement sash for casement windows, choose the correct color as they cannot be painted later. Finding replacement moving parts or moving metal parts in long run is not that easy in most cases (especially the new ones).

#Broken Hardware

If you cannot operate you casement window, first clean the hardware and lubricate it with lithium grease. If it’s still troubling, then you proceed with the replacing idea.

Every piece of the hardware including crank, hinge, and lock can be replaced as they are seized with screws and matching alternate hardware is available in the market.

Just unscrew them, take it to the casement window hardware supply stores and get yourself an identical one. There are many companies producing hardware and it varies from one brand to another.

So, make sure you carry the hardware or all the related information to the store.

#Damage to a Window Seal

Variable temperature causes the window glass to swell or contract. In fact, it expands or contracts more than glass panes. Over time, the seal between the glass and the frame loosen.

Some experts would suggest that you replace the entire window. However, you can remove the sash while you patch it up so that the glass doesn’t skid into the frame after you eliminate the caulking.

Always be watchful while you do so, as you don’t want to deal with broken glass later and spend money on glass replacement or glass repair.

#Worn-out Crank of A window

No need to replace a whole casement window just because you cannot open or close the window completely. It won’t take you more than an hour to fix it.

Step 1

Check the crank for any abrasion or exposed gears. If you find any, you have to change the full crank mechanism.

Use locking pliers to open the window. Press down on the arm to open the crank arm brushing from the track and shove it out of the window.

Step 2

Unscrew the trim; elevate the casement cover off the jamb. Then, unscrew the crank. If you find any bent or rusted screw, better change those.

Step 3

Compare the old one and purchase a matching hardware. Place the new crank aligned to the old holes. If the holes are exposed, fill them with a few toothpicks then bolt in.

Refasten the crank arm and steel casement windows cover that you have detached earlier. Try closing the steel windows to check the lock engages well! This ensures the proper functioning of the locking mechanism.

For DIYers

Consider the following if you’re considering replacing your casement windows because they let in drafts, fog up easily, or are difficult to open and close. You can fix most of the window opening issues for a fraction of the cost of new windows, and it won’t take you more than an hour or two to repair each window individually.

Windows are often the source of problems. Casement windows, along with doors, are the primary contributors to heat loss in the majority of dwellings. When painted, they may also become difficult to open, and humidity may cause them to swell and cling shut.

Internally, there is a possibility that the shades and Venetian blinds will not function properly; glass will be cracked, and screens will be destroyed. In the following paragraphs, we will discuss the solutions to the casement window glass issues seen most often.

You won’t need any specialized equipment, and the components may be purchased from most window manufacturers or through online window supply companies or yellow pages.

Instead of waiting a week for the repairman to arrive and repair casement windows, you could do this window repair independently. Doing little repairs around the house may provide homeowners with several financial benefits.

Do-it-yourselfers who are just starting will find that fixing a casement window is an easy undertaking. Get the necessary specialty tools (like rotary tool), then mend the damaged casement window.

How to Repair a Window Crank Handle That Has Been Stripped

If you turn the handle on your window and nothing occurs, the gears on your handle, the crank operator shaft, or both may be stripped. Remove the handle so you may inspect it for any indications of wear. If the teeth are worn, the handle has to be replaced.

You may get a new one from the window manufacturer, through a window dealer, or by searching for “window replacement parts.” It is possible to replace the whole operator if the shaft has become worn. First, though, you should give this home treatment a go.

To begin

unscrew the handle by turning the set screw counterclockwise. Some contemporary handles do not have setscrews and may be removed by simply pulling them off; however, this remedy will not work for such handles.

Mark the location of the setscrew on the operator shaft when the window is closed, and the folding handle is in its folded-up position if your window has a folding handle.

First, remove the handle, then use a file to smooth the shaft so the set screw can fit onto it.

It is important to remove the shavings from the operator using a vacuum cleaner so that they do not cause damage to the moving components.

Reattach the handle using a longer set screw (sold at hardware stores). It’s possible that this remedy won’t hold up in the long term if you often open and shut the window.

How to Repair a Window That Is Stuck Open

If opening a window causes it to drag against the frame, you should shut it and check the problem from the outside. The sash should have a squared-off appearance and be centered inside the frame.

In such a case, you may change the position of the sash by repositioning the hinge channel just a little bit.

You may move the channel at the top of the window or the channel at the bottom, depending on which way the sash is dragged; however, you cannot move both channels simultaneously.

To begin

First, make a mark on the frame to indicate the position of the hinge channel, and then unscrew the channel. In the case of vinyl windows, epoxy or wood filler may be used to fill the screw holes (wood windows).

Filling weep holes ensures the screws will not realign themselves with their previous positions when you replace the channel. Before the epoxy has time to cure, scrape the filled holes until they are smooth.

After moving the channel away from the side of the dragging sash and positioning it back on the jamb with an overhang of approximately 1/8 inch from the mark, you will need to drill pilot holes measuring 1/8 inch and then reinstall it.

Casement Windows

A window with a hinged sash that can be opened in or out like a door is known as a casement window.


The typical materials used to construct a casement window are metal and wood. A single or double hinge attaches the frame to the window sash. There is often a cranking mechanism referred to as an “operator.”

This mechanism is linked to a channel on the bottom of the frame through an arm. When the sash has been closed, a lock will grab it and pull it close to the frame until it is secure. A crank or cam handle, typically situated at the bottom of the casement window, is used to open or shut the casement windows.

Why clean?

The answer to a casement window that is difficult to operate (that is, it felt stiff while opening and closing) is often as easy as cleaning and lubricating the gears of the carrier or any other moving metal elements in the window. Cleaning keeps your windows in good shape.

If there is damage to a metal component, then it is quite probable that the damaged component will need to be replaced and you will have to find new replacement parts.

Possible options

Examine the window frame carefully if you notice that shutting the window is difficult even though the lock and the operator function properly. The window is often obstructed by dried paint, which prevents it from functioning normally.

It’s possible that scraping and sanding the dried chunks of paint is just what the doctor prescribed. There are instances when a simple bare wood binding is required. In such a case, the sash would need to be planned to achieve the desired level of precision in its fit.

Operator arm

The operator arm is yet another common location for malfunctions in the machine. The arm of certain casements moves along a track, which is almost always obstructed by dirt and other material particles.

Your casement window’s smooth operation may be ensured by first using a wire brush to clean the track located on the bottom of the sash and then using a cloth that has been soaked in a solvent to wipe the track clean.

If a window handle turns but the window does not unlock, this can only signify that the splines in the handle or the splines on the operator shaft are entirely stripped.

Our problem may be solved by going to the hardware shop in your area and purchasing an adjustable new crank so that it can be used with a range of different spindles. Put on the appropriate ring, connect the handle, and then screw on the set screw until it is as tight as possible.

Find the best alternative

Locating the appropriate replacement components might be challenging at times. If you can locate the device’s make and model, you will have a better chance of getting a price quotation from the manufacturer.

Final Thoughts

Vinyl Casement Windows are expected to last at least 20 years with a rare occurrence of you holding the screwdrivers. It is not necessary that you have to call the experts, but you can repair it yourself and hoard some cash and serenity.
