Measurement and Installation Guide

Often spring and spiral balances need replacing or can be used instead of weights on sash windows. Here’s how to install one yourself. Remember that if you are unable to safely secure a window balance then you should always hire someone to fix it for you.


We advise that you give yourself around an hour to install spring or spiral balances, since they must be done safely and properly.


  • Spiral or spring balance
  • Foot attachment
  • Screwdriver and screws
  • Scraper blade


  1. When removing a pre-existing sash, you must ensure that the inner or outer beading is removed from the window so that the inner sash an swing out of the frame. It’s removed by putting scrapers between bead and frame and hammering them in. Don’t use tools that will damage the window.
  2. Once you’re ready to install, then the spring balances can be unscrewed at the top. Make sure that tension on them is at zero by tugging the bottom end down and unwinding the tension in a controlled manner. If you unscrew the top without doing this step then it can cause injury as the screw flicks out.
  3. Put a screw through the top spring balance hole then put it back into the sash grooves. Get the sash back into the frame whilst holding the spring balance in place.
  4. Let the sash sit low whilst you refit the beading you removed earlier. Press the scraper blade on the bead to set the required gap then use a hammer to fix a pin into the bead.
  5. Slide the sash almost to the top as this will set the potion of the spring balance.
  6. Use your tensioner tool to turn it before slotting it into the bottom of the sash and adjust the tension until it runs correctly.
  7. Count the turns on both sides so they are tensioned equally, or the window will get jammed.
  8. Replace the sash and the beads.
  9. Sometimes you will need to repaint the window after installing.
  10. Congratulations, you’ve now installed your new spring or spiral balance.


What does a spring or spiral balance do?

A spring or spiral window balance is used to act as a force on sash windows so that they are easy to open and safe. They sometimes need replacing or can be an excellent option instead of weights or a pully. There will always need to be force involved in opening and closing sash windows due to friction, but with spiral and spring balances you will have ease-of-access.

How do I know which balance to buy?

Choose you spring balance by finding out the weight of the window that you’ll need to counter. This will then help you establish which product to buy. Weigh the sashes and the groove diameter to find a balance that matches your needs.

Will I need any other equipment to fit my spring or spiral balance?

If you are fitting a spring balance then you’ll need to purchase a Balance Tensioning Tool. This will set the tension of the upward force that acts on a window. It’s achieved by twisting the lower end of the spring until the sashes have the same amount of force to push them up, as down.

How do I know which foot to buy?

Horn foots are perfect for spiral balances whilst a standard foot will fit spring balances. This way you know how to find the correct fitting for your balance and sash window.

When will my balance arrive?

We offer shipping across the mainland UK, which will arrive within 1-3 days, or there is a next day delivery (including Saturdays) courier option on all our items. We also provide trade orders for large projects.
