We were called out to this property in Gerrards Cross because the homeowner was concerned about the mist that had started to form on the double-glazed windows. Although a frame is designed to expand in the cooler and warmer months, this can, over time cause the seals to become loose. Weather damage is also a very common cause of broken seals. 
Our team was able to establish the cause of the misting quickly and replaced the sealed unit. Boking a misty window evaluation with us is quick and easy, and we can offer a full diagnosis and price of repair on the same day.
