Your Questions, Answered

Sliding Windows FAQs

Can I customize my sliding windows?

You can choose either a 2- or 3-lite design, making the sliding window style perfect for customization. With a unique rolling hinged design, this window easily opens vertically or horizontally in your space.

Are sliding windows durable?

Yes! Our window frames are made from virgin vinyl with the color formulated right into the vinyl so they’ll never chip, peel, crack, or warp. That means no painting, sanding, or staining, just wipe with a soft cloth and all-purpose cleaner to keep them looking like new.

Could sliding windows lower my energy bill?

Yes. Window World of Long Island’s Sliding Windows are designed for energy efficiency and year-round performance. The multi-chambered sash and mainframe create insulating air spaces for superior thermal efficiency, plus they feature ENERGY STAR-rated insulating glass packages.

Will my purchase be protected by a warranty?

Yes. Each window is backed by Window World’s limited lifetime warranty, protecting your investment for the long-term.

Are sliding windows easy to clean?

Window World’s EasyGrip sash lock allows the sash to swing in smoothly. This superbly engineered pivot system means you can easily clean the sash from inside your home.

What is a sliding window?

Also known as slider windows, sliding windows have sashes that can slide open or closed. Sashes on sliding windows are designed to move back and forth horizontally, unlike double hung windows, which have sashes that move up and down vertically.

How do you clean sliding windows?

To properly clean sliding windows, you’ll want to remove both window sashes. To remove your sashes for cleaning, follow these steps:

  • Slide the sash towards the opposite side, leaving a gap of about 3”.
  • Lift the sash as high as it will allow.
  • Pull the bottom of the sash inwards towards you and remove it from the rail.
  • Carefully lower the right sash to the floor so it can be cleaned.
  • Slide the sash towards the opposite side, again leaving a gap of about 3”.
  • Raise the sash as high as it will allow.
  • Pull the bottom of the sash inwards towards you and remove it from the rail.
  • Carefully lower and place the ash onto the floor where it can be cleaned.

How do you put a sliding window back in its frame?

Removing and reassembling sliding window sashes is much more simple than it may appear. To put your sliding window sashes back in place, follow the steps below:

  • Push the top of the exterior-facing window sash up until it sits in the outer window track (the track closest to the exterior of the window). Continue providing upward pressure and push the bottom of the window sash into place on the lower track.
  • Next, push the top of the interior-facing window sash into the upper track (on the interior side of the frame). While continuing to apply upward pressure, push the lower portion of the inner window sash into the lower track until it is securely in place.

How do you measure sliding windows?

When replacing windows, you should always have a professional take measurements before making a purchase. That being said, if you’re interested in measuring sliding windows, please follow the instructions below:

  • Remove your sliding window sashes from the window frame and place them carefully on the ground or in a safe place.
  • Begin by measuring the width of your window frame, specifically the space between the window jambs on either side.
  • Next, measure the height of the windows, at the most narrow point.
  • Finally, measure the window depth by taking measurements of the space between the outer and inner window stops.

We just had six windows installed and were completely satisfied with the whole process. The work was completed quickly and efficiently without any major problems and we are planning to have six more installed next year. Thank you Jacob for your follow up.

Buying a house full of windows, 2 triple sliders, and a new front door is a daunting task. We did our homework and it was also the 3rd house we redid. So we had plenty of experience. From the start, Matt was patient and easy to work with. No overselling, just great advice, and really good service from the installers. A fantastic value, for good quality products. From really nice people. Highly recommend.

It was a pleasure having our windows installed by Window World. Their prices are very reasonable and their work was neat, clean, and started and finished when promised and we are very pleased with the results. They installed 13 windows (2 that were new installs and had to be cut and fit not just replace a 6 foot sliding glass door that also had to be cut and framed. All done in 2 days by 2 men. AMAZING.
