very reliable, did everything he said he was going to do. tidied up at the end of each day. he even stayed late some nights because he knew there was bad weather coming. job done in 3 days. everything now water tight and weve had some heavy down pours of rain since the job has been completed. very nice and polite man. nice to find a tradesmen that does what they say they are going to do. would highly recomend.
