This article will look at the work required to install vertical blinds in an interior window and will consider the potential problems and pitfalls associated with the task.

Costs involved with installing blinds

A blind installer will cost between £65-£125 per window. The price depends on the number of windows you need blinds installed to and the experience of the installer the cost could vary.

What installing blinds entails

The fitting of blinds will entail determining the correct size and drop of your window, the drilling of holes in the correct place to suit fixings and the mounting of the blind in the correct place. The job may involve cutting the length of the blind if it is bigger than your actual window.

Other jobs to tackle

Since you will be effectively coving up a portion of the window for all of the time and the rest of the window for some of the time, now is an ideal time to look at the general condition of your window and frame and clean them with a damp cloth or even redecorate as necessary. If you do redecorate, wait at least 24 hours after decorating for the paint to dry before fitting the new blind.

General advice when hanging blinds

There are a number of different types of blind available on the market, including:

  • Vertical blinds
  • Roman blinds
  • Roller blinds
  • Venetian blinds
  • Wooden blinds
  • Faux-wood blinds
  • Pleated blinds
  • Perfect Fit blinds

Most of these use the same kinds of fittings, being some means of securing the blinds either inside the window cavity or directly outside of it. You’ll have to decide which type you want to fit and then understand which mode of fitting they require. Once you have that information, you move on to measuring.

You need to measure the window to determine what length of blind you need. You’ll also need to measure the drop – how far it is between the top fixing position and the bottom of the window, plus a little bit more to ensure that the window can be completely covered. Once you have those measurements, you can obtain your blind.

If there are directions that come with your blinds, you need to follow them along with the steps listed in this guide. You’ll need to create some pencil marks so that you know where your brackets go.

For an outside mount, hold up the blind so that the headrail (top part of the blind) is centred and levelled with your window’s alcove. Make a pencil mark right below the headrail on each side of the casing. You should also make a mark a quarter of an inch past the end of each headrail.

For fitting an inside mount, place the headrail inside the window alcove. It should be level-keep your handrail level, even if the window isn’t. Draw pencil marks below the headrail on each end.

Your blind will have been supplied with two brackets – one for each end. You need to fit one of these aligned with the pencil marks at each side of the window. These are normally fixed using two or four screws and, whatever the number required, you should hold up the bracket and mark the hole positions on the wall with a pencil. Drill the correct sized holes, and fit the wall plugs in. The brackets are now read to be fixed to the wall.

You need to check that the actual blind is the length that you require. If it is too long, you may have to cut it down the blind to fit. This can be a very complicated process and needs to be carried out in the correct way. To do this effectively, you need to follow the next series of steps, which are for a slatted blind, which is the most difficult type to shorten.

  • Take out any plugs positioned on the lowest side of the bottom rail to free the string ladders and the tied lift cord.
  • Unfasten the lift cord and pull it up enough to free the slats you need to get rid of.
  • Take away the bottom rail and the slat(s) required to shorten the blind to the wanted length.
  • Slot in the bottom rail back into the ladder rung where you took out the top slat.
  • Lift and tilt cords on horizontal blinds. Cutback the string ladder directly above the rung that’s under the bottom rail. Ensure that you have enough ladder hanging under the bottom rail to put in these strings into the holes on the lowest part of the bottom rail.
  • Place in each of the lift cords in through the bottom rail hole and make a knot. Ensure that the lift cords are level and that the bottom rail hangs evenly. You might have to adapt the location of the knot to accomplish the wanted length to your blinds. Don’t try to alter the length by pulling on the lift cord.
  • Change the bottom rail plugs back into the holes on the lowest point of the bottom rail. Use a rubber mallet/hammer to prevent marking the plugs.

Shortening a fabric roller blind will involve unrolling the blind, cutting through the top rail, then marking the length and cutting through the fabric with stout scissors. The bottom rail will need to be removed and cut to the right length.

Once the blind has been cut to the right length, you can fit the top rail into the brackets, securely close them and check that the blind operates as intended.
