  • Perfect professionalism from first point of contact to cleaning up after work. Very consistent and thorough in communication. Prices are upfront and fair and most importantly - finished product is perfect. So happy I found them on Checkatrade and decided to solicit a quotation from them. Local London shops and nationwide leaders didn't measure up!
