Terrible After Service!

Apalling after service!!! Undertook roof repairs and provided a 10 year guarantee on the waterproofing. This did not last for even a year! I've had endless issues with leaks in the same place with no proper resolution. Shalin sub-contracted the waterproofing work and has not been on site since the job was completed. He is taking no responsibility and is not honoring the guarantee provided. Does not respond to messages or calls! For a woman to be taken advantage of like this is absolutely disgusting!
