Why Are My Windows Hard to Open & Close?

When windows are new, they glide open and closed with little effort, but over time, their operation can become more difficult—especially if they have not received proper upkeep and maintenance.

Many people never give their windows a second of thought until they are not working properly. Cleaning and lubrication of moving parts are a vital part of keeping your windows operating smoothly and easily most of the time. However, there are a handful of issues that can make your windows difficult to open, even with routine cleaning and maintenance.

In the sections below, we’ll discuss common issues that can make the most popular types of windows in use today difficult to open.

Difficulty Opening and Closing Single or Double Hung Windows

Single and double hung windows are most often difficult to open due to a buildup of dirt, dust, and debris over time. As the buildup worsens, friction increases, making the windows very difficult to open and close.

Since this is the most likely cause, start by cleaning the window frames and spray with a non-silicone, solvent-free lubricant. Open and close the window several times to work the lubricant in.

If the window is still difficult to open and close after doing this, your problem is likely associated with a spring that is too tight. Adjusting (or replacing if necessary) the spring should return the sash to its normal operation. If you’re uncomfortable adjusting the springs in your windows, contact a professional, who can get the windows back to working order in no time.

Trouble Opening and Closing Awning and Casement Windows

Awning and casement windows have more points of failure than single and double hung windows, so the cause for these windows being hard to open and close can be a variety of things.

The best place to start is to remove the sash from your awning or casement windows. The method for doing this can vary depending on the window brand, so consult the instruction manual for your particular windows for more information on how to do this properly.

After you have successfully removed the sash, check for stripped or loose screws. If you find any, this is likely the cause of your problem.

If the problem continues after replacing stripped or loose screws, or if you do not have any, lubricate the hinges with a silicone or dry Teflon spray lube. Work the lubricant into the hinges by opening and closing the windows several times.

If you are still having issues after trying the two methods above, it is likely that you have a malfunctioning operator. Contact your window manufacturer for replacement parts or a local window repair company for repair services

Common Problems with Opening and Closing Sliding Windows

Sliding windows are simple windows, relying on rollers and a sliding track. They are the easiest type of windows to open and close—often requiring just a push of the finger. If they become difficult to open, the problem most likely lies with the roller system.

First, clean the roller system and track with a simple soap and water solution. In many cases, this will solve the problem, but if it does not, lubricating the rolling system should solve the problem.

If the problem continues, your rollers are bad. Contact your window manufacturer to buy replacement rollers or contact a local window repair company.
