Window Installation & Replacement

Window Installation & Replacement – section 1
Windows affect how a property looks, feels, and stays warm or cool. At DS5 Construction Ltd, we install windows chosen for their appearance, strength, energy efficiency, and how well they fit your building.
We work with uPVC, aluminium, and rooflight windows, offering solutions for both traditional and modern properties across London. Good fitting is just as important as the window itself. Careful measuring, putting the window in the right place, sealing well, and leaving a neat finish all help the windows work well over time.

Window Options

  • uPVC Windows
    These windows are a practical and budget-friendly choice. They offer excellent warmth, easy care, and come in many styles - including sash, casement and tilt-and-turn - to match your taste and needs.
  • Aluminium Windows
    Aluminium windows are best for modern homes and large glass areas. They have slim frames, are strong, and look stylish. You can choose from different types such as casement, tilt-and-turn, bay, or fixed windows.
  • Rooflights
    Used to bring in more daylight from above, roof windows are especially useful for making rooms brighter and providing better overall light.

How we deliver it

We ensure openings are properly checked, tolerances are controlled, and junctions are sealed correctly so that the finished installation performs well in terms of heat retention, weather protection, and overall finish.
