"I'd just like to place on record my thanks for the service I received in response to my concerns about possible subsidence last week. Not only did I get a very prompt visit from Robert, but the advice came in a totally comprehensible (I'm not at all technically minded!) and reassuring form, followed by a written explanation and recommendation. While I obviously hope that my property doesn't need additional investigation in the future, I wouldn't hesitate to contact your company again if it did. I wish all businesses were as prompt and helpful as yours obviously is!"
