Reviews
-
Very pleased with the loft hatch, Easy to fit and very good quality.
-
Good value for a made to measure hatch and well made. No problem fitting although I did have to patch up the plaster around the edge, this would have been avoided if I had ordered the wider frame. Only comment would be that it would have been even easier to fit if hatch was removable.
-
these hatches are low cost, i was a bit unsure, but when it arrived i was greatly surprised, measurements were accurate and once fitted it was a nice snug close, wife was also happy and because of the large lip on the hatch i only needed to do very little remedials. would not hesitate to recommend this product.

Very pleased with the delivery time, quality and fit. It would be ideal if the hinge could be removed to allow easier fitting of the frame by one person.

From the time we ordered this Jupiter Blue where in contact to ensure details were correct and to our required specifications. I had made a mistake in the order so they were able to fix this before the unit was built for us. Top quality product and first class service. Will recommend this firm.
