Window installations

Rising energy bills giving you sleepless nights? Can’t take a nap because of the traffic outside? Why not switch to uPVC double glazed windows? They :

  • Are low maintenance
  • Offer efficient thermal insulation
  • Are soundproof, which is why they are able to block out the outside noise
  • Come with the latest safety features

      Need new uPVC units? Contact L & O Windows Ltd today! We will visit your property, design your windows and install them with fine finishes.

      We can install:

    • Casement windows
    • Tilt and turn windows
    • Sliding sash windows
    • Composite doors

      Our composite doors are finished in white, red, green, blue, black and light oak. They are an ideal replacement for your lovely old, wooden doors, that are more prone to droughts. Made using strong, durable GRP material with a textured wood grain finish, they look similar to wooden doors and look perfect for old homes as well as modern houses. Our composite doors have been tested for: water tightness BS5368-2, air permeability BS5358-1 and wind resistance BS5368-3.

      Entrance doors

      All of our uPVC doors have severe weather rating and hold the prestigious Police Secure by Design award. They come with a marine-specified locking system with anti-salt corrosion protection, whose strength is twice the strength of the BS7950 security standard.

      The visually attractive, fully sculptured profile can be designed to match your uPVC windows. We have a wide range of lead, bevelled and coloured glass designs to meet the most discerning taste. Discuss your ideas today and watch them turn into reality.

      You can choose from our wide range of colours and finishes, including white, rosewood (mahogany) or cherrywood (light oak). You can even mix and match the colours and finishes as per your choice. We also supply and install handles, letterboxes and door knockers.
