I cannot fault SdPh from start to finish.
Pre sale: I was guided through the process on the phone by a really helpful team. Lots of options to choose from and I paid over the phone with my credit card to help spread the payments over the year.
Post sale: One of the team kept me informed on how the test construction in their workshop was going and double checked photos of my patio for the delivery. We agreed a date which I had to push back 1 day for personal reasons which they accomodated.
Install: They built the entire thing within a day. (although someone came back the next day to replace one of the faulty light bulbs) All the electrics are seamless and I just plug it in every morning with the cable provided into my garage plug socket.
It looks really high quality, too early to see how the product weathers over time, but they give a 10 year warranty (and I have added a waterproof coating to all the wood to help keep it looking nice! Thanks SdPh Team!
