Absolute professional.Very knowledgeable. Our father in law had engaged a company recommend by the local county council. They charged£60 upfront which they said covered 3 visits. The first visit they left bait and the operative reported that he didn't think there were any rats in loft. They arrived next time without ladders this operative said he was not aware the problem was in loft. Next operative came and said that it was over run a health hazard and he needed to take all insulation lagging out put a galvanized partion up to prevent the rats comings in from next door. Cost£1800+vat. My wife told me and because Mark had done several jobs for me i asked him to go and access the situation. Mom and dad who are 87 and 91 agreed. Mark said yes there we're rat's but not overrun or was it necessary to do all this work We engaged him his quote was £510 Inc vat. He is always busy but well worth the wait
