i Fix Roofing & Chimney - honest reviews?

Google reviews are all 5* and some look like bots as nearly all reviews are 9 or 11 months ago. Has anyone any honest reviews of working with these guys? Jason main man. They have given a good price to my mum but she desperately needs it to be a good job as replacing a roof that’s only 11 years old. Can hardly afford it. So I really want to trust the workers she gets.
