At the top of the very best companies I have ever dealt with. From the beginning of the process to the final installation, the customer service was of the highest, communication being both informative and regular. Both the installers were brilliant lads, technically knowledgeable, friendly, respectful and hard working (they never stopped) and tidy. The added and pleasing bonus being that one was a Son of the owner. I think that says it all, you get what you pay for using this Family run business and it shows Sam and Gordon went the extra mile and did a superb job using an excellent product. Just make sure you have plenty of coffee in the cupboard. Highly recommended.
