I understand this concern; Why would a company like ours offer a free of charge service? It sounds too good to be true.
The truth is, we do offer this service and there is no catch. We do not work for any other agency and we do not pass on any of your information to anyone else.
Before we can make any recommendations, we like to know the full picture. The easiest way to do this is for us to get in the car and visit site. Of course, being a business, we hope that you may spend money with us at some stage but I can assure you our first approach is as engineers. We want to understand the problem and identify the best solution for you. If its work that we can do, we would send you a quotation and then leave it with you to decide what you wanted to do.
