Window Repair Cost

How much to replace a broken or misted up window?

Double glazed windows can at times mist up internally, this is caused by a breakdown of the seal between the two panes of glass, it’s not uncommon but thankfully a relatively easy and inexpensive fix. The installer will usually need to visit your home to measure up for a new sealed unit. Once this has arrived it’s simply a case of taking the beads out and installing the new pane of glass.
