So easy to deal with, now roof hatch fits like a glove. Excellent from start to finish and so easy. Thoroughly recommend. :):)

Hi I love the window/access hatch. Seems really good quality. Only complaint is the lack of detailed information on the built in upstand i would receive. The dimensions given were fine for the opening. Not so the footprint of the upstand. I have it sealed perfectly but the upstand is slightly overhanging the setting i had prepared. This means some extra GRP work next year. Not till we have wall to wall sun though! Great product but needs links on seller site to the installation details /product specific .

Purchased a Mardome Trade access hatch to allow access to a flat roof, to use as a roof garden. Very pleased with the quality of the access hatch. Was easy to fit and looks great fitted, especially now that the artificial grass and a selection of plants are in place. Price was the best I could find online after extensive searching. Fast delivery too. Everyone I spoke to in customer service were very pleasant and helpful any time I called them. The first hatch I received had been quite badly damaged in transit by the courier service. I refused delivery and the courier took it away. Trade Access Panels were very helpful and supplied a second hatch in a matter of days with no fuss, no arguments, no hassle. Would definitely use the company again and recommend to others 100 percent. Thanks to all at T.A.P.
