We had two patio covers from Sunshield installed in 2001...17 years ago and we have not had any problems, they both still look like new. One time we had a bolt come out probably 10 years after install and I called Them and the owner came over the next day and totally replaced the whole pole with no questions asked. I highly recommend Sunshield because they stand behind their work. They also put in a cover for my daughters home when she built and the cost was very reasonable too. We could not be any more happier with Sunshield, they are a true, honest and solid companyj
