Took my deposit money in Feb telling me the enclosure would be installed "next week, or in 3 weeks at the latest". Then gave me weak excuses for over 3 months for delays, no-shows, etc.
Very difficult to raise on the phone. Don't let the fancy website fool you: It's a father and son with a pick-up truck and a mobile phone. They rarely answer the phone. Especially once they had my deposit.
Eventually showed up but didn't have the materials to do the job and said they'd need to come back "another day". I cancelled the contract at that point and was assured I'd get my deposit back.
This proved to be yet another unfilfilled promise and to date still haven't recd my deposit back.

AVOID AVOID AVOID!!!
This will end up in small claims court. But I hope this warning will be useful so you don't end up in the same situation.
