If the sash on your casement window is stuck

First, check the sash lock mechanism to make sure it’s completely unlocked. Then turn the handle slightly and push very gently on the sash near the lock mechanism. The sash should pop open. Open the window, and check the surface of the weather-stripping. You may want to apply a thin coat of dry lubricant to prevent sticking.

If your hung or slider window isn’t opening as smoothly as before

Check to see that the operating sash guide is clean. Over time, dirt and debris can settle in the guide, making it difficult to open and close the sash. Try cleaning with soapy water and a soft brush, then wipe with a clean, damp cloth to remove soap residue. You should avoid scrub pads and abrasive cleansers.

After the area is dry, applying a Teflon or silicon-based lubricant to the area will help the sash operate smoothly.  If cleaning doesn’t do the trick, you may have a problem with the installation – click here to contact us for assistance.

Cleaning vinyl windows

You don’t need to do a lot of maintenance work on uPVC windows and doors: no painting, staining, or treatment. From time to time, just clean the interior and exterior frame with a soapy household cleaner diluted in water; use glass cleaner without ammonia for the glass.

Most casement windows open a full 90 degrees

for easy cleaning, while hung windows tilt in.

To open casement windows a full 90 degrees

Simply turn the crank until the window is open. You’ll be able to reach the outside surface for easy cleaning.

To tilt hung windows for cleaning

Open the bottom sash about three inches, then use both hands to open the tilt latches on both sides simultaneously. You’ll be able to reach the outside surface for easy cleaning.

To clean window and door hardware

Wipe them down with mild soapy water, then wipe with fresh water to remove soap residue, which may prevent proper operation over time. You can also lubricate hinges with a dry Teflon or silicon-based lubricant.
