We have a semi-circle window which is quite high up and has condensation within the two panes of glass since we moved into our house. The window is towards the top of a second storey house and after getting quotes for a replacement we found a sign for get the fog out. The man I spoke with was very pleasant and was able to give me a rough estimate over the phone. The crew was professional and cleaned up after themselves. It was a quick fix and saved a lot of money.
