Every uPVC supplier & installer will tell you their windows are the best, but they can’t all be the best – can they?

The design of the uPVC window has largely stayed the same since their introduction in the 1980’s. There have however been many advances in Security and Thermal efficiency.

Not all windows measure up, yet you could be persuaded to pay good money for them…

You’ll be pleased to hear that we ONLY install windows in to YOUR home that we’d be happy to have installed in our own homes and that’s a promise!

Your new Windows will be:

  • A+ Rated (applies to all uPVC casement windows)
  • Double Gasketed
  • Lead Free (our Liniar profile is 100% lead free)
  • Secured by Design (the official police initiative), optional upgrade
  • BBA Approved (the Liniar window system has been certified and approved proving its qualities)
  • Professionally installed
  • FENSA certified
  • Insured and Guaranteed

How much will my new windows cost?

There are many variables to consider, such as: Size, Number of Openers, Colour, Double or Triple Glazed etc…

As a rough guide, based on a 3 Bedroom Semi Detached House with 8 White uPVC Double Glazed Windows you would expect to pay in the region of: £3,500 – £4,500 fully inclusive of: Full Technical Site Survey, Manufacture, Installation, Making Good and all Guarantees.
