I've been using dryseal for about 2yrs now, I had seen it used 3/4 years prior to that, I couldn't believe How good it looks, and how well the system works even on small details, Where other products would look messy or fail, I as a company, would highly recommend the product And the help and support of the team at dryseal to any potential customer Thanks for help and support Colin (. cj roofing )

Disgusting customer service sending bullying emails to an elderly gentleman who needed assistance from you regarding your product which you installed on his home which is now failing and is still in guarantee period under your product guarantee of 25 years. When he emailed asking how you could blame the installers (as this was you who did the remedial works on the initial faulty product) instead of a reply he got a miss sent email which was clearly meant for internal not a customer speaking about him in a disgusting manner!
Absolutely disgraceful! Instead of sending snide emails about customers that have used your faulty product and are now asking for the faults to be rectified maybe you could focus your customer service department on actually helping your customers and not bullying and upsetting vunerable people.
