Your beautiful bi-fold doors may be perfect for connecting the outside to your home but what about bugs? Knowing how to retrofit fly screens means you can enjoy the cool breeze of a summer’s evening without worrying about how many unwanted creatures are sneaking into your home.

Installing a fly screen on your bi-fold doors, sliding doors, french doors and windows means you can open them any time you want. And it's a job that any competent DIYer can tackle. But be warned most self fit solutions aren't suitable for large wide spaces. So, to fully appreciate your outdoor space you may need to call in a professional.
