Composite Decks in Los Angeles County, CA
Low maintenance composite decks from Trex and TimberTech, built to look great and hold up to the Southern California sun for decades.
Professional composite decks across Los Angeles County
Composite decking is the top choice for LA County homeowners who want a beautiful deck without the sanding, staining, and sealing that wood requires. Made from a blend of recycled wood fibers and polymers, composite boards resist fading, staining, scratching, mold, and rot, and most carry warranties of 25 years or more.
We install the leading composite brands, including Trex and TimberTech, in a wide range of colors and finishes, using hidden fasteners for a clean surface with no visible screws. The result is a deck that looks like premium hardwood but only needs an occasional wash to stay looking new.

For most homeowners, yes. Composite costs more up front but needs almost no maintenance and lasts 25 years or more, which often makes it cheaper over the life of the deck.
Composite can warm up in direct sun like any decking. Lighter colors and cool deck product lines stay noticeably cooler, and we help you choose the right board for your exposure.
We install leading brands including Trex and TimberTech, which offer strong warranties, fade resistance, and a wide range of colors.
Composite decks only need occasional cleaning with soap and water or a gentle wash. No sanding, staining, or sealing is required.
