  • What Are The Benefits of Double Glazing?
    Here in Scotland, we’re no stranger to cold weather, but you’re still powering your central heating system more often than necessary if you don’t have double glazing.

New windows and doors

We recently got new windows and doors replaced throughout. Also French doors installed in place of a window by Sure Sealed.

The whole process from start to finish was very straight forward from our first meeting with Craig we knew this was the type of company we wanted to use, no hard sell and unbiased advice on which products/finish we should get.

The quality and finish of work was excellent. I would definitely recommend to others.


Great experience

Great service from measuring to installation. The guys from Sure Sealed got stuck in to the job and cleared away all rubble and mess. Left me with perfect fitting and great looking windows.

Thank you. Will recommend to anyone looking for new windows or doors.
