Safe and Secure

Your safety and security are our top priority at Marathon Windows. We understand that homes in Mitcham need to be secure and offer peace of mind to the residents. That’s why all our double glazing products are Secure by Design accredited, which is a police-backed initiative used to improve building safety regulations.

Double glazing is a secure option compared to single glazing as it has an additional pane of glass, providing an extra layer of protection against any breakage or force. With Marathon Windows’ double glazing options, you and your loved ones can have the peace of mind that your home is safe and secure.
