Recent Review: I'm in Palmdale CA, 15th Street W. and Avenue O. Sure glad I found United Carports! Great customer service, Diane promptly answered my many questions. We communicated mostly by email with a few phone calls. She promptly adjusted price based on my several changes to specifications and options. Price was VERY good compared to others after much online shopping and estimates from local contractors. I got the certified plans from United Carports and used those plans to get the permit for LA County (a "learning experience"). I was quite nervous about the down payment and $500 for the plans as I didn't know if plans would be approved. After a couple of mods to the plans and about $3500 to the County, they were approved much to my relief. It took about 3 months for County to approve them. After finally getting approved plans, I got a local contractor for the concrete floor, he just followed the plans and did an excellent job. Then United Carports sent out a team to put up the building. It took about 2 1/2 days. It was obviously an experienced installation team with 2 to 6 installers working on it at any given time. I'm VERY happy with the results, it is rated for 110 mph winds per County requirements for Antelope Valley so it is a little more sturdy than the standard frame. The building isn't perfect but I didn't expect perfection for the price. The building is sound and was wind/rain tested a couple of days after the install. I got some drafts and blow-in around the bottom base rail. I asked United Carports about methods for better sealing . I was just looking for some tips on getting a better seal and fully expected to do it myself. But the next day one of the owners made the 4-hour round trip to my house to help with sealing! Awesome customer support after the install! The standard roll-up doors are a bit "cheesy" but quite serviceable. I ordered optional seals around them but they still won't be sealed well around the sides. For the price, I didn't expect any better. If I decide better roll-up doors are needed in the future, then it appears it won't be difficult to replace them. Windows and walk-in doors were good quality. Overall, a great experience working with United Carports customer service and the installation team. I am quite impressed with the final product, it exceeds my expectations. HIGHLY RECOMMENDED!
