Any slight gap between shutter frames and the recess wall can be in filled with decorators caulk. Available from all DIY stores.

If at first panels do not line up, unscrew part of frame and play with its position as, as little as 2mm movement can affect the hanging of your shutters.

For white shutters, white caulk can be put into frame holes before the wood caps & also a little afterwards. Then smooth over with a clean soft cloth.

Ensure that the frame has been installed where the window has been measured. Not all windows are square so if you measured up tight to the window the same frame may not fit at the front of the recess.

French doors have 3 sides of frame with no piece on bottom, full height generally have 4 sides of frames & tier on tier panels have 4 sides of frame.
Where there are large handles on a window ensure you fit frame in recess to allow sufficient clearance for slat tilting.

That’s it. Congratulations on a job well done. We hope you enjoy your shutters for years to come. Finally if you do encounter any problems during your installation then call our team on 0845 123 5661 for help!
