Replacement Glass Units

Another service that Harvey’s Windows are pleased to offer is the replacement of glass double glazed units.


If one or more of your double glazed sealed units (the individual glass units found within double glazing installations) is broken or misted up between the panes, we can manufacture and fit a replacement unit so you won’t have the cost of replacing the whole window.


The reason why a double glazed sealed unit “breaks down” is because the perimeter seal fails. This can be affected by prevailing weather conditions, the initial manufacture of the unit and also the fitting of the frame and the unit within it. Some cleaning materials can also have an adverse effect on the integrity of the seal.


Once the perimeter seal has been breached moisture can penetrate through the seal and is drawn through the unit as it heats up in the sun. Once this has happened there is no cure and over time looks more and more unsightly.

We would recommend that it is much more cost effective to replace the unit with a brand new product than try and repair the unit. You can also take the opportunity to upgrade to a higher specification of glass unit if the frames you are fitting into make it worthwhile. These newer glass products and spacer bars are more thermally efficient, especially if the unit is filled with argon gas. (ie. they let less heat pass through keeping you warmer in the winter and cooler in the summer).

Units can be fitted into upvc, wooden or aluminium frames and the whole range of glass designs and toughened glass is available.

Harvey’s Windows provide replacement glass units to customers across Leicester and the surrounding areas of Leicestershire including Loughborough.
