Martyn & his partner were nice on the phone and in person, and made helpful suggestions, tried to keep costs down etc. However, when their initial fix failed to cure my problem, they made a date to attend again and look for other causes, but never showed up. I got no responses to my phone calls or answerphone messages, and have never heard from them again. I wouldn't have minded if they couldn't make the agreed date and time, or even if they couldn't fix the roof, but they could have let me know. Irritating to have to remain at home just in case they did eventually arrive.
