While the price quote from this company was reasonable the service was quite poor. After the first call to them, it took a couple of weeks to get someone out to measure up - despite initial assurances of a visit the next day.
On installation day the installer turned up 2hours and 40minutes late, after 4 calls to their office. No compensation was offered for my wasted time beyond an apology from the receptionist.
If you use this company then be prepared to chase them!
