Deck cover, patio cover, pergola installation

Add a covered space to your deck or patio
The perfect compliment to your deck

Fixed covers are a great way of shielding you and your deck from sun, rain, hail, snow and other weather conditions. Whether you’re looking for a pergola or deck cover, you can count on 3 Brothers Decking to build one to your specifications using the best materials and quality craftsmanship.

Deck covers

Deck covers allow you to enjoy your deck year-round, providing a solid ceiling. They give excellent protection against rain, snow, and excess sunlight. Subsequently, this also increases the longevity of your new deck.


Pergolas are great for partial sun blocking and also work well with hanging gardens. Pergolas are constructed by aligning parallel boards on top of a base formed by long posts to create an open ceiling.
