    Post sleeves

    Posted by Jeffrey Heffern on Jun 18 2019

    Post sleeves arrived when expected from Deck Expressions. The delivery service however dropped something on the box, and one of the sleeves was cracked. Waiting on a replacement from Deck Expressions.

    The good condition sleeves which we installed were easy to cut to size, and installed perfectly over the existing deck posts, and look exactly as we hoped.

    Posted by Louis Economo on Oct 7 2018

    Product is good but shipped in a bag as opposed to a box sometimes makes susceptible to damage in shipping.

    Great fitting product, I was told at my local home improvement store they no longer made sleeves and that I would need to get a wrap. Found this online and could not be happier. Color matches perfectly with my décor and the fit was perfect, just cut to length and put on the cap. Good shipping as well, product was well protected.
