What Customers Are Saying

Customers overwhelmingly praise this PVC trim for eliminating wood rot and maintenance in damp environments like bathrooms and exterior frames. Most highlight its maintenance-free performance, noting it won't rot, swell with humidity, or require painting. Many emphasize how easily it cuts with standard miter saws, screws cleanly, and installs like wood but better. Reviewers love the bright white finish requiring no priming or painting, and appreciate its lightweight nature and professional appearance. A few report minor issues with straightness or saw blade gumming, but these isolated concerns barely diminish the strong consensus that this delivers long-term durability and ease.

poor delivery system

Would Recommend

i ordered from north Scottsdale store, All items were in stock. order was transfer tro 29th Ave store, 1 mile farther away. that location split the order to 2 separate deliveries. One was just 10 pieces of PVC 4"x8' trim boards. Second deliver balance of order. Two 18 wheel trucks to deliver items that could have been in a small panel van or pickup. 2nd delivery arrived 45 minutes later in a pickup truck with one person to unload. Last time I use Lowes delivery service.

They work well outside

Would Recommend

The boards thatbi purchased were pretty scuffed up and have marks that wont washnoff. Its not the end of the world as they are getting painted but i expected them to be a little tougher than they are. Allnin all they are ok. Of note these are flat, not textured.

Good all around trim

I like this trim because it’s low-maintenance, doesn’t require painting, has consistent color throughout when cut, and holds up well around moisture. This made it ideal for our workshop and also made it a bit more polished looking.
