How to install

How To Install A Bay Window

We would not recommend that you attempt to install your own bay windows, but, if you choose to do it, here is how!

1. First of all the fitters will remove the existing window or cut a new hole in the wall where the bay window will be positioned.

Removing windows can be quite a dusty, messy experience, but using quality installers will ensure that it is carried out with as little disruption as possible.

2. Once the window has been removed, the installers will then create the new box into which the frames will fit.

3. The window frames can then be installed into the box frame.

4. The roof will then be installed and sealed correctly, usually using lead, trims and final sealant will be applied to ensure a weatherproof seal is made.

5. Finally, the glass can be installed, and cleaned-up and wiped down will be carried out.

Hanging a curtain for each section:

This option can get extremely fiddly and finding curtain poles to fit each frame can be hard; if you do manage to pull it off; however, it can create quite a spectacular feature in the room.

Hanging a curtain across the front of the bay:

This option is by far the most straightforward. However, seeing as you have already paid for the expensive part, we would advise that you choose one of the above options to really give your windows the finish they deserve.

However, if you like the look of this option, it is effortless to complete. Simply hang a curtain pole stretching the width of the front of the bay, and hang your curtains and position your tie backs.
