Misted & blown glass sealed units

Replacing a double glazed unit is usually done when the window frame is still in good condition, but the glass has failed and become misty or appears “steamed up”.

Why replace a double glazed unit?

• Energy efficiency

  Double glazing helps keep heat in your home, but if the seal breaks, warm air can get in and reduce the window's efficiency, leading to higher energy bills.
  Old double glazed units are a lower specification to modern ones, so we can also replace these units with new which increases their effectiveness.

• Condensation

  If the seal breaks, moisture can get into the unit and cause condensation on the inside of the glass.

When to replace a double glazed unit?

• If the window is steaming up or has condensation on the inside
• If your energy bills have increased

The lifespan of double glazed windows is usually 15–20 years, but this can vary depending on the quality of the window, how it was installed, and how well it's maintained.
