  • We offer a wide variety of VEKA windows.
  • Whether you are looking for casement windows, Vertical Sliders (sash) or Tilt and Turn, we can offer you a vast array of colours and finishes to complement and enhance your home whilst improving the level of security and warmth. It’s your choice!
  • We use ‘A’ rated VEKA windows as standard although other options are available. Modern uPVC windows provide an excellent thermal barrier even in the most exposed locations.
  • Our windows and glass are the latest design energy efficient. They offer added protection and security (shoot bolt multi locking system).
  • We offer VEKA Fully Sculptured windows as standard (other options are available) which look more attractive than the average uPVC window featuring curved moulding on both sides of the frame.
  • We only offer top of the range window furniture (handles, hinges and locks) to compliment your window/s and provide longevity and added security.

  • We build your conservatory to the highest standard using a winning combination of VEKA frames for the windows and doors and Ultraframe for the roof.
  • We can offer advice on Building Regulations and can apply for any relevant Planning Permission on your behalf.
  • We can complete the base of your conservatory for you or offer dimensions to allow you to choose another contractor.


  • We offer a wide range of door styles for the gateway to your home.
  • Whether you are looking for a secure new front door, elegant French doors, sliding patio doors or contemporary bi-folds, we can offer an option to suit you and help you complement and enhance your home. It’s your choice!
  • For front and rear entrance doors there are two main options:

Composite doors which are made up from several different materials-a composite material sub frame supported by timber stiffeners and pressure filled with an energy efficient foam, all encased in a surface material of Glass Reinforced Plastic (GRP). This gives the look and feel of a wooden door but is more secure and requires far less maintenance.

uPVC Panel doors are made from panels of uPVC with areas of glazing. A wide choice of styles options, door combinations and colours are available
