The Hidden Dangers

A Deck is Only as Strong
as its Structure.

In Los Angeles, a "cheap" deck often means skipped permits and hidden dry rot. We bridge the gap between a weekend DIY project and a certified, structural extension of your home.

The "Cheap Build" Risk

The "Cosmetic" Fix

Hidden Dry Rot & Termites

Many contractors just "face-lift" a deck by replacing top boards while leaving rotten joists underneath. This is a recipe for collapse.

Unsafe Ledger Attachment

If the ledger board isn't properly bolted and flashed to your house, it pulls away over time, causing the deck to sag or detach completely.

Unpermitted Work

Building without LADBS approval means you might have to tear it down when you sell. "Cash deals" offer zero legal protection.

The GAGA Guarantee

Structural Integrity

LADBS & Fire Audit Ready

We handle the engineering and permits. Our decks meet Title 24 and WUI (Wildland-Urban Interface) fire codes, so you pass City Inspection every time.

Deep Structural Repair

We expose the frame. We replace rotted joists, install Simpson Strong-Tie brackets, and pour new caissons if needed to ensure seismic stability.

Flashings & Waterproofing

The #1 cause of rot is water intrusion. We install commercial-grade flashing and waterproofing membranes to protect your home's rim joist from water damage.

Los Angeles Deck Engineering

Built to Code. Built to Last.

Deck construction in Los Angeles is governed by the LADBS Building Code, focusing on seismic activity and fire safety. Whether you are in a High Fire Severity Zone or building on a steep hillside, we engineer your deck for safety and longevity.

Hillside Engineering

We specialize in cantilevered decks and steel moment frames that require complex caisson foundations for stability on steep slopes.

WUI Fire Compliance

For homes in Wildland-Urban Interface zones, we use Class A fire-rated decking and enclosed soffits to prevent ember ignition.

Waterproofing

We protect the ledger board connection with commercial-grade flashing to prevent water intrusion, dry rot, and mold inside your home.

Code Legalization

Buying or selling a home with an unpermitted deck? We can retrofit the structure to bring it up to code and close open permits.

The Deck Safety Checklist

We inspect these 4 critical failure points on every project.

Common Questions

Answers about dry rot, hillside permits, WUI fire zones, and LADBS requirements for Los Angeles homeowners.

Can you repair my deck without tearing it all down?

Often, yes. If the structural framing (joists and beams) is healthy, we can perform a "Resurface". We remove the old, splintered top boards and railings, then install new Composite or Hardwood decking. This saves you thousands compared to a full rebuild.

Do I need a permit for my hillside deck?

Yes. In Los Angeles, any deck over 30 inches high requires a permit. Hillside decks have stricter requirements, often needing soil reports and structural calculations. We handle the entire LADBS permitting process for you, ensuring your deck is legal and safe.

I live in a Fire Zone (WUI). What material should I use?

For High Fire Severity Zones, we recommend Class A Fire-Rated Composite (like specialized Trex lines) or ignition-resistant hardwoods like Ipe or Mangaris. We also install enclosed soffits to prevent embers from getting underneath your deck.

How do I know if my deck has dry rot or termite damage?

Look for soft spots in the wood, deep cracks, or a "bouncy" feel when you walk. Check where the deck connects to the house (the ledger board); if this is rotting, it is a major safety risk. We offer a Structural Inspection to identify these hidden issues.
