Cheapest isn’t always the best

Cavass provided a simple and effective service. I needed to have a chimney removed and was tempted to go with the cheapest quote, but after carrying out checks on the builders I'm glad I went with a more reputable firm instead. It's true, ultimately, you get what you pay for.
