Rest assured that the replacement double glazed window or door system, whether it be aluminium, upvc or timber, you purchase through us will conform to a very high standard.

When it comes to a “standard” product we are miles in front of our local competitors. We do not offer upgrades on security or insulation because we offer the best “as standard”!

We only fit high security door locks with added “hooks” or “claws” to prevent the replacement doors from being forced open, shoot bolts are fitted to double doors. Any in-fill panel will be reinforced, lock barrels are made from specially hardened steel and toughened glass it always fitted.

Our replacement double glazed windows are all fitted with top and bottom shoot bolts with vertical mushroom catches which again stops the frames from being forced open.

If you are not satisfied by our security, we can offer a special guarantee which will cover the cost of a new window, if the window gets forced open during a burglary.
