Do NOT order from this company. We sent them the correct measurements for the windows - my husband is a builder and it is not difficult for him to measure correctly. The slats were too long for two windows, one slat was missing on another window, and another part was missing on another blind. So in total out of 15 blinds 4 were faulty. I have been trying to get them to sort this out over the last month, and they are making every excuse possible to avoid rectifying their error. Our windows sizes have not changed! We are asking that they send the correct length of slat for the depth of windows we gave them two months ago, instead of the slats that are too long. They are making every excuse under the sun - "send this photo, send that photo, Oh I can't see from that photo, how long they are, we need to see how long they are so that we know what length to send next time. " I gave them the measurements when I ordered them. Those measurements have not changed, so why can they not calculate what drop the slats should have been. That is what they do - make blinds! They ask you for this photo, then ask you for all other sort of things, then tell you they have to speak to production, and then wait a month before they tell you they cant see the measurements in the photo. It would be a lot simpler and cheaper for the company to just send out the replacement slats. Will never deal with this company again. Go to Blinds2Go. I dealt with a fab guy on the phone who was very happy to spend as much time as necessary to get velux blinds sorted, and when they arrived they were of excellent quality and VERY reasonable and fitted like a glove. So Blinds2Go for me anymore
