## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "We found KMC windows via a recommendation from a friend, I was looking for a few weeks to find a good installer I felt I could trust. The team at KMC were clear and transparent throughout the process. They came out discussed what I was looking for and provided a very simple quote. They were reasonably priced compared to some quotes I had been given, and kept things simple. We spoke via phone and email and their responses were quick and clear. A date was agreed the installer turned up on time, was very tidy, cleaned up as he went and worked throughout delivering to a very high standard. Really happy with the work they did. The knackered old windows being replaced has made a great difference throughout the house. Very happy, no surprises, no issues."
