[Top»] Why should I use a Window Repair Engineer?

A Window Repair Engineer has all the relevant tools to remove the glass from the frame safely, without damaging the frame or the glass. The Engineer also has the experience to deal with the different frames that are currently used, and will probably have their own techniques to get out the glass.

Another reason to use a Window Repair Engineer is that they are insured, so if they remove the glass and then drop it and it shatters, then it is down to the Window Repair Engineer to replace that pane of glass. If you remove it and then drop it and it cracks, it is down to you to replace it and is a further cost.

We all take windows for granted, yet we would all like them clean, take the hassle out of trying to remove it yourself and call a Window Repair Engineer.

[Top»] How much does it cost?

As with everything, it depends what type of work needs to be carried out and how long the job will take. Some Window Repair Engineers will charge by the job, and others will charge by the hour, so it’s worth asking your Window Repair Engineer which way they charge.

If the seals in your frames have gone and you get a ‘steamy’ patch in your window, this will be a different price to a small window repair if the Window Repair Engineer charges by the job, however it could be the same price if the Window Repair Engineer charges by the hour, as they could take similar lengths of time.

[Top»] When should I use a Window Repair Engineer?

If your double glazed windows are becoming steamy, then it is usually down to the vacuum seals failing and allowing air to get between the two panes of glass. The change in temperatures from the inside of the house to the outside will cause condensation between the two panes of glass, resulting in that steamy appearance.

Another way in which a Window Repair Engineer can help, is if you have damaged window frames, then the Window Repair Engineer can replace the damaged section (if it isn’t too badly damaged) or replace the whole window frame unit to suit the existing frames.
