The right decking material for your home and budget
Composite decking from brands like Trex and TimberTech resists fading, staining, and rot, needs no sanding or sealing, and typically carries a 25-year warranty. It costs more up front but almost nothing to maintain, which makes it ideal for busy LA County homeowners who want a deck they can forget about.
Natural wood such as redwood, cedar, and pressure-treated pine offers a warm, classic look at a lower up-front price. It rewards a little care with decades of service and can be refinished to any color. We help you weigh appearance, maintenance, and cost, then build it right either way.

What Los Angeles County homeowners say
“Job well done guys, highly recommend!!”
Javi TalbotGoogle Review“I would have loved to see photos of your work on the website, but overall it’s great.”
Chalino SanchezGoogle ReviewDeck building questions from LA County homeowners
In most cases, yes. Decks over 30 inches above grade, attached to the home, or over a certain size require a building permit from your city or the County of Los Angeles building department. Diamond Deck Builders prepares the drawings and pulls every required permit for you, then coordinates inspections through final approval.
Most deck projects in LA County range from about $25 to $60 per square foot installed, depending on materials, height, site access, and features. A pressure-treated wood deck sits at the lower end, while premium composite decks with railings, lighting, and multi-level designs cost more. We provide a detailed written estimate after a free on-site consultation.
Composite decking (Trex, TimberTech) costs more up front but needs almost no maintenance and resists fading and rot for 25 years or more. Natural wood like redwood or cedar is more affordable and offers a classic look but needs periodic staining and sealing. We help you choose based on budget, appearance, and how much upkeep you want.
A typical residential deck takes one to three weeks of on-site construction once permits are approved. Permit processing adds a few weeks depending on the city. Larger multi-level or commercial projects take longer. We give you a realistic timeline in your written proposal.
