Single Hung Window Replacement

What Are Single Hung Windows?

Single hung windows, also called Sash Windows are a standard choice for modern homes. They are easy to use, have a thin profile that gives you a contemporary look and maximum view, a sash that slides up and down, and they are usually able to tilt for easy cleaning.

Benefits Of Single Hung Windows

Single hung windows are excellent. There are a lot of different types of windows, so it’s important to know the benefits of the window style that you’re interested in.

Single Hung Windows Pros

  • Weather Tight Seal – Dual weather stripping keeps the outside, outside, and the inside, inside
  • Easy To Clean – A tilt-in bottom sash that creates easy access into nooks and crannies
  • Save On Energy – Energy efficient design
  • Versatile Look – The flat exterior frame is convenient for lap siding or brick construction
  • Low-maintenance – The vinyl never needs painting

Single Vs Double Hung Windows

Double hung windows are typically more expensive because both the top hash and the bottom hash move. The fewer moving parts of the single hung window means less cost, which is typically why new home builders will often choose the single hung – to keep project prices low. Make sure you ask your window installer which they are installing.

On a single hung window only the bottom sash moves, and on a double hung window, both sashes move.

Double hung windows have two ways to decrease energy efficiency – the top and bottom sash. Both panels have to be properly weather stripped, and closed to maintain efficiency. Often times the top sash isn’t closed properly which creates a draft.

Single Hung Window Sizes

You can have your windows made in any size if you have custom needs. The standard size of a single hung window is 24 inches x 36 inches, but the actual size is 23.75 inches x 35.25 inches.

Single Hung Window Repair

Most repairs done on windows are replacements of the balance springs (or just balancers). Those are often easy to repair, and can be done by you. To replace the springs, remove the bottom sash window and replace the springs. See the Milgard Balancer Replacement video for detailed installations.

When it comes to replacing glass for windows, it can be time consuming if you’re unfamiliar with the process. Breaking parts is also a possibility. Double and triple pane windows only add to the time, effort, and cost.

We suggest replacing the entire window or panel (sash) for fastest service.

Single Hung Window Replacement FAQs

How do you lubricate a single hung window?

To lubricate a single hung window just spray silicone lube onto a rag and wipe the lubricant onto the window track. This is along the jamb liner. Do not get silicone lubricant on vinyl or glass.

Can a single hung window be repaired?

Yes, single hung windows can be repaired.

How does a single hung window work?

Single hung windows consist of a top window (sash) that is fixed – does not move – and a bottom window that slides up and down.

Should I get double hung or single hung windows?

The answer depends on your preference. Do you want only one of the sashes to move or both? Both sashes moving increases airflow and makes cleaning easier. Only one sash moves in a single hung window, and both sashes move in a double hung window. A single hung window is less expensive than a double hung window.
