Glazing work refers to the installation, repair, or maintenance of glass or glazing systems in buildings. This can include a wide range of tasks related to glass, such as installing windows, doors, skylights, curtain walls, or glass partitions.

The benefits of glazing windows include improved energy efficiency, noise reduction, enhanced security, UV protection, reduced condensation, and improved aesthetics.

Yes, window replacement is often worth the cost due to increased energy efficiency, improved aesthetics, enhanced comfort, and potential long-term savings on energy bills.

The cost of new windows can vary widely depending on factors such as size, material, style, and installation requirements, but generally, prices can range from a few hundred to several thousand dollars per window.

Double glazing reduces noise by creating a barrier between the interior and exterior environments, with two panes of glass and an insulating layer of air or gas between them, which helps to absorb and dampen sound vibrations.

Our Wide Range of window and door Colours are white, black, anthracite grey and RAL Colors.

To repair a double glazed window, identify and replace damaged seals, fix any hardware issues such as hinges or locks, and address condensation by sealing any gaps or leaks in the window frame.

Yes, secondary glazing can work on larger windows, but it may require additional support and customization to ensure proper installation and effectiveness.
