ULTRA HIGH SECURITY
This brand new product features five locking points in total, including four opposing hooks, which are secured in the fully thrown position when the central brass deadbolt is engaged.

5 points of locking.
4 hooks. (double the standard )
A central brass deadbolt.
Anti-jemmy protection.
Increased positive frame connection.
Better weather sealing.
A simple day latch function.
The BRAND NEW 5 Point Locking system will be available on ALL ENDURANCE DOORS fitted with Lever Handles AS STANDARD. It will also be available for just £50 as an upgrade to Endurance Doors in our special offer range!

The "Hunter" Sledge Hammer Test!
Do we all remember 90's ITV show Gladiators? If you answered yes, you should remember Hunter. Most of our female customers seem to remember him anyway!
Now simply known as James Crossley, he seemed the perfect icon to gather some hired muscle and put our Endurance Doors to the test, by trying to smash one down with sledge hammers.

If you have questions that aren't answered on this page, give us a call on 0800 865 4745, send us an email or visit our Frequently Asked Questions page. We're here to help!
WHAT ARE THE MOST IMPORTANT THINGS WHEN CHOOSING WHERE TO BUY?
Just as you do when buying a new car, a new house, a holiday or having home improvement work performed etc - research the company, check their awards & reviews, check their certifications, check if they offer a guarantee and consider whether it is worth the paper it's written on, ask questions about the products and check that they actually know the products well and remember that the cheapest price is NOT always the best price! Also try to plan ahead - will the company still be around in the months and years to come to support you if your products need adjusting or should any other technical issues arise that require attention?
Design the door of your dreams...
Design your dream door online in the comfort of your own home, office, a train, a restaurant or even a comfortable toilet seat! Superimpose your design onto a photograph of your house and keep going until you find the exact door that you require. Then, simply submit your enquiry to request a totally no-obligation quotation from one of our in-house Composite Door experts. We will respond to all enquiries within 24 hours Monday-Friday, usually much sooner.
Survey, Supply & Installation.
Every day of the week we install Windows and Doors for Homeowners and Landlords across South Wales. Collectively we have in excess of 150 years worth of experience in double glazing products, including uPVC Windows & Doors, Composite Doors, Aluminium Bifold Doors, Conservatories and replacement Conservatory Roofs. Our fitters are qualified and time served experts in their field and install thousands of products every year. They are are certified under our CERTASS scope and we invest in our local youths by offering apprenticeships to train and progress the next generation of window and door fitters.
What makes us different?
Unlike many other companies, who follow a dated and unethical procedure that we do not agree with, we do not charge commission, we do not increase the price you have signed for following a survey, we will always tell you how to make your quotation less expensive - we would rather you spend less, tell more people how impressed you've been with us and return for more windows and doors in the future! We do not employ commission based sales staff. Other than our fitting teams, the entire company is family run by the expert Father, Mother, Daughter and Son-in-Law management team.
Can you beat any quote?
There are quite literally thousands of combinations of door style, colour, glazing, hardware, frame style etc. If you have a design you would like us to match please send us a copy and we'll do our best to help you. We're happy to try and match or beat any like-4-like quotations you have received from other suppliers, as long as they are legitimate, include VAT and are not cash sales.
Please be aware that we provide premium products, so will not be able to match the prices of inferior alternatives.
