Misted double glazing in Harpenden

If you’ve noticed condensation or fog trapped between your window panes, you could have misted double glazing. This usually means the seal around your window unit has failed, allowing moisture to get inside.

Fortunately, a misted double glazing repair can restore both the appearance and insulation of your windows without the cost of full replacement.

What causes misted double glazing

Misted double glazing happens when the airtight seal around the glass breaks down.

Over time, temperature changes and exposure to the elements can cause seals to degrade, leading to moisture build-up inside the unit.

Common signs include:

  • Hazy or clouded glass
  • Visible water droplets
  • Reduced heat efficiency

A specialist can reseal or replace the affected unit to bring your window back to full performance. It’s often much cheaper than fitting an entirely new window.

How much does misted window repair cost?

The cost of misted double glazing repair depends on the window size, location, and how many units are affected. On average, expect to pay £60-£120 per window for resealing or glass replacement.

Large or hard-to-access windows may cost more, while small panes are usually cheaper.

If several windows are affected, many tradespeople offer reduced rates for multiple repairs. Getting a few quotes is the best way to confirm what’s fair for your property.
