Jason from See-Through got up on our heritage roof to do a patch-test to confirm results before providing a roof-cleaning quote in May 2015. How’s that for good service! His quote was more than reasonable and he provided lots of advice on other value-add options we were under no obligation to take up. He was incredibly courteous and professional and did a smashing job, leaving everything neat and tidy. I couldn’t recommend Jason and See-Through highly enough. Thanks so much!
