Without the use of your company I would have had to embark on pulling up every floorboard in my house, meaning lots of stress and mess. As it transpired, my leak was detected in the cavity wall of my home, where the central heating pipe goes through the wall. It was found by emptying my system and filling with tracer gas. I am glad I used yourselves and you found it in half a day without the need for hiring a plumber and joiner who would have turned my house upside down and never found anything as the leak was actually in the wall. Got npower out to replace the pipe and all has been ok for 3 days now. Thanks LDS. Highly recommended and appreciated. Oh, and I was covered through my Buildings Insurance for trace and access.
