We love our pergolas! Very easy to put together. It was a cheaper way to cover our back patio for the time being! We just bought our house back in September and wanted to give our patio a cozy feel for the summer nights coming up soon! It also helps with the rain hitting our basement doors! I did spray each canopy, top and bottom, with a waterproof sealant for extra protection before attaching them onto the pergolas! We have had some heavy rain storms and they have held up very well! The only thing is that I have to go out and hit the water out of the canopy after a rain storm so that it’s not just sitting on there. It only catches on the 3rd row up right above the row with the drain holes. Other than that small thing, we couldn’t be happier with our pergolas! We have had so many compliments! High quality look for a cheap price!
