Reviews

Was a bit dubious as the price of a made to measure loft hatch was so much more than the standard model but having a house with a wide loft entrance meant that I could not find a standard one to fit antwhere. So I purchased a made to measure one and was so glad I did. Item was delivered well protected, easily with specified time frame and litteraly took 15 minutes to fit. Deffinatelty a two person job. The time saved from making and fitting my own loft hatch negates the extra expence. Highly recommended product and Company,

Came across Jupiter Blue when searching for a loft hatch suitable for our rather large loft hatch opening. The custom made option meant that we didn’t have to mess about making good as we went for the larger flange size. The hatch arrived within the timescale and was easy to install (definitely a two person job due to size/weight). Fully recommended and will certainly use Jupiter Blue again in the future.

The new loft hatch looks and fits great. My wife is delighted so I can’t say anything better except to recommend you to anyone needing a replacement hatch door.
-
A straightforward order process, and on-time and an excellent quality product that was simple to fit.
-
I had an unusual size loft access space, which needed a bespoke size hatch. Placed the order on-line giving measurements exactly as requested. Delivered ahead of the time specified, securely packaged - and fitted very well indeed. Would definitely recommend and use again if needed.
