Secure Front and Back Doors

Whether you want to replace your front door or add a seamless transition between a home and garden, we can help. We offer a range of styles from secure composite doors to aluminium sliding doors which will flood your property with natural light and popular uPVC doors.

All our doors feature robust and long lasting double glazing, protecting your home and your loved ones. These doors will not become compromised in adverse weather conditions and will need minimal maintenance to stay looking as good as new.


Versatile Extensions

Expand your Dunstable home to accommodate a new working space, a spot to socialise with the family or a new room for your little ones to play in. We offer a range of house extensions, conservatories and orangeries that deliver on performance and aesthetics.

No matter the style of extensions you choose for your home, you will be able to use it all year round. These spaces are crafted with premium double glazing which means they won’t overheat in summer nor become like an icebox in winter.

Our extensions are tailored to your requirements, lifestyle needs and space available. Add as many windows and doors as you like, creating the right space for you and your family.

Thermally Efficient Investment

Our double glazing has been designed and fabricated with thermal efficiency in mind. Our windows and doors work hard to ensure that your Dunstable home stays consistently comfortable. In winter, your central heating should stay inside your home and won’t seep outside.

Even in the coldest of winters, you should rely less on your central heating which could lead to minimised energy bills. As well as your central heating becoming minimised, the carbon efficiency of your space will also be diminished.

Market Leading Security

We know security is a priority. That is why all our double glazing is crafted using high grade materials and state of the art manufacturing techniques. Our entire range of double glazed installations are fitted with security features like high quality locking mechanisms. Keep your loved ones, home and belongings say with our windows, doors and extensions.
