All our windows and doors are fitted with cutting-edge security systems, including multi-point locks. The uPVC and aluminium profiles are known for their rigidity and will keep your home secure. Our locks go through regular rigorous testing.

Tailored Design

Made with the UK in mind, our products will secure your home from even the most extreme weather. We fit our modern house extensions with robust materials, including weather seals, to prevent unwanted water ingress and draughts from entering your St Albans home.

Low Maintenance

The modern house extensions that we create are designed not to warp, rust or discolour. They work against all elements and require little maintenance. St Albans will only need to wipe down any moveable parts with a damp cloth from time to time.

Double Glazing

All our windows and doors are fitted with high-quality double glazing. The two glass panes trap the warm air and keep it within your home. The outer pane blocks the cold from seeping into your property. You will rely less on using your heating and lower your monthly energy bills.


Our modern house extensions are designed to be long-lasting. The strength of our materials will protect you from any unwelcome intruders. Our locks are tested to ensure that they meet the latest safety regulations so that you can feel safe in your St Albans home all-year-round. Our internally beaded glass cannot be removed from the outside.
