I must have been the odd one out as my feedback is negative. Just make sure you get exact measurements, in writing, of what they are making for you, as my porch was made much smaller than the original, which is what they came out and measured. I, unfortunately, could not prove this fact!
The initial survey recorded the size of my original porch, which I stressed that I wanted maintained. Unfortunately, no measurements were ever given to me, I just trusted them. The 3 pieces that I was given the option of keeping or cutting off would, in hindsight, have been the depth I originally ordered, but there was no roof section over the pieces so I had them cut off. I had not realised at the time that my porch was 7 inches less deep than it should have been!
