Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.

Right product, right price, right delivery.
Right product, right price, right delivery. Sure, it was only one length of cast iron guttering but they took the order seriously, packed it well and kept me updated on delivery. And when I opened the very good packaging I found it was exactly what I had wanted. How can you do better!!
