I bought a double door had on going issue from day one , Same as lots of other people.. First the colour black is not black Wind whistling through Bubbles in the door appear in many places Joints cracked in several places now the lock won’t open spent over £2000 for what was supposed to be the best door in the market Rockdoor are always looking to blame and put the faults down to something else Not good when they manufactured it Hopefully they read this review along with the others below and take some responsibility for there product,, I look forward to a positive reply as now we’re using the back door to get in and out the house As a after care service it’s poor as they wouldn’t even send someone out to look at it ,,
