Replacement Sealed Units for Broken or Damaged Double Glazing

Double glazing is an essential feature of modern homes, providing not only improved thermal efficiency but also noise reduction and increased security. However, accidents happen, and over time, wear and tear can lead to the need for window repairs.

Why do sealed units fail?

Sealed units fail for a variety of reasons. It could be a crack in the actual glazing, or the age and general condition of the window. There may have been a problem with the manufacturing or installation process, leading to failure, or as a result of cleaning materials that over time have damaged the seal.

When a sealed unit is broken, damaged or worn out, it loses its insulating properties, leading to increased energy bills and a less comfortable home environment. Broken glass can pose a safety risk, while condensation inside the unit can obstruct views and diminish the aesthetic appeal of your property.

We understand the importance of maintaining the integrity of your double glazing. That’s why we offer a comprehensive replacement sealed unit service. Our expert team can replace damaged or broken sealed units quickly and efficiently, with minimal disruption.

Replace or repair?

Why would we rather replace a broken or damaged sealed unit than repair it? Well, repair costs can be expensive and a repair might not restore the window’s original thermal efficiency, leading to increased energy bills due to heat loss. A repair could also mean that moisture is still able to get between the panes, leading to condensation that obscures visibility.

When compared with the costs and risks associated with repair, we would recommend replacement every time.

Quick and Efficient Service

Our replacement process is designed to be as quick and efficient as possible. We can often replace sealed units without the need to remove the entire window frame, saving you time and money. We use only the highest-quality materials in our replacements, ensuring that your new sealed units provide the same level of insulation, security, and aesthetics as the originals.
