Hard to Open Windows? Here’s What you Need to Know.

August 13, 2021 0

Often the reason windows are hard to open and shut is because they’ve not been properly maintained. Windows are finely engineered, rely on moving parts, withstand extreme weather, and are built to last a long time. A well-maintained window will operate smoothly for many years.

Although Brock windows are known for their durability and we provide an industry-leading warranty, proper maintenance is still required as windows operate on simple mechanical principles.

Read below to understand how these popular window styles operate to assist in diagnosing your issue.

Single and double hung windows simply move up and down in channels in the window frame. Balancing mechanisms, such as rope and pulley, spiral or block and tackle, assist in raising and lowering the window sashes, and prevent them from sliding downward.

Single and double hung windows become difficult to open if there’s a buildup of dirt, dust, and debris. Over the years, friction from the buildup increases making the windows difficult to open and close. Try cleaning the window frames and spray with a non-silicone, solvent-free lubricant, opening and closing the window several times to work in the lubricant.

Casement and awning windows operate by a crank handle and a track. The windows are opened and closed by means of a crank mechanism, which resides against the frame on the inside. The crank houses a series of gears inside a metal housing, which moves a control arm, attached to the sash, which slides along a track.

Casements and awnings that are difficult to open and shut may require removing the sash and checking for stripped or loose screws. Before doing so, please contact your window manufacture as this could affect your warranty.

Once visible, lubricate the hinges with a non-silicone, solvent-free lubricant, and then open and shut the windows several times to work in the lubricant. It is helpful to keep the gears lubricated to make turning easy by applying a few drops of oil around the base of the handle if it’s difficult to turn. 

Sliding windows rely on rollers and a sliding track, like a sliding door. Opening and closing simply requires a subtle push. Sliders that are difficult to open and close may require a thorough cleaning of the roller system and track with a mild soap and water solution. 

After eliminating the above causes of hard to operate windows, if your windows still don’t open with little effort, it may be time for a window replacement. If the time has come for your window replacement, reach out to our expert team at Brock Doors and Windows Ltd. to assist with your next project.
