5 of my units of various sizes in the main house and conservatory have misted window panes, internally. I have emailed locally and have received estimates ranging from £185 with 10 year warranty to £290 with 5 year warranty.
Superficially they all seem to offer the same service, remove old sealed unit and fit new. But with such prices and warranty differences, I think I may be missing something. (No! Not a screw icon_smile.gif ).
Are there more questions I should ask of the firms to ensure that I get a good job at reasonable price?
BTW I live on the Hants Dorset border.
