Review: The Best Products for Blown Window Repair in the UK in 2022


Glazed windows are a worthy investment for your home. They block outside noise, keep your home warm and enhance your house’s energy efficiency, thus saving you money.

People are likely to ignore a misted window until it’s too late and needs to be replaced. Even if a seal in a double-glazed window is broken, it can cause a blown window. Therefore your home must remain dry.  

There are different factors to consider before deciding whether to repair your blown window or replace it. They include:

  1. The type of glass

There are three different types of glass on a double-glazed window. These are:

  • Safety glass
  • Enhanced glass
  • Low-energy glass.
  1. The exact cause?
  • Is the misted glass due to a broken seal?
  • Is it too old? For instance, has your window serviced you for more than 10-15 years?

In this guide, we’ll look at the repair cost of a blown window in the UK and if it’s possible to do a DIY.

Blown Window Repair Cost in The UK

The repair price varies according to location and the extent of the damage. However, the standard cost ranges from £100 for a small window, £200 for a medium window, and £300 for a large window.

These prices do not include the labour cost of the tradesperson and the transport cost of the windows. Depending on the job’s complexity, a professional can take from 45 minutes to a day and they will charge between £300 – £750 depending on your house and the job description.

As not all misted windows require replacement unless they are too old, smashed or cracked, you may be able to repair them on your own using various tools. A DIY job can save you the cost of hiring a tradesperson and other additional charges that come with window replacement.

The Best DIY Blown Window Repair And Cleaning Tools

Repairing double glazed windows by yourself can be a daunting task. In addition, grime and dirt build-up can cause the window seal to break, hence letting in moisture into the thermal space of the windows, which can cause condensation and mist. Carrying out a DIY window repair requires knowledge as any slight mistake during the measurement can cause continuous leaking of cold air or outside noise.

Below are some of the must-have tools, especially if your home has glazed windows, because of the higher risk of their becoming condensed or misted.

  • It can clean hard-to-reach corners.
  • It has six sponges that take in all water and moisture.
