If your deck in Hollywood, West Hollywood, or North Hollywood is showing soft spots, bubbling paint, peeling coating, dark moisture stains, or leaks into rooms below, it likely needs a new waterproof coating. These issues get worse just before rainy season, so recoat early to prevent wood rot, mold, and costly structural damage.
Hollywood decks take a beating. Between long months of direct sun, the heavy morning marine layer rolling in from the basin, and sudden winter storms that hit Los Angeles without warning, your deck’s waterproof coating works harder than most people imagine.
If you live in Hollywood, West Hollywood, or North Hollywood, you already know how quickly moisture creeps into a deck. Homes near Laurel Canyon, Sunset Boulevard, Melrose, Highland, and Lankershim often deal with hidden leaks because many decks look fine on the surface but are failing underneath.
Before the rainy season arrives, here are the seven clearest signs your deck needs a new waterproof coating—and how to stop the damage before it spreads.
1. Peeling, Flaking, or Cracked Deck Coating
If your deck coating is peeling like old paint or cracking into thin lines, the protective membrane is no longer sealing the surface.
In West Hollywood, this often shows up on decks that get full sun exposure above garages or units on Fountain Ave, Santa Monica Blvd, and Fairfax. Constant UV breaks down older systems like acrylic coatings or DIY roll-on products.
Why it matters:
Cracks allow water to slip underneath the coating, which leads to rot, mold, and rusted fasteners.
What you should do:
A professional waterproofing contractor will strip old coating, repair the substrate, and apply a new system such as Life Deck, Dex-O-Tex, or Westcoat for long-term performance.
2. Dark or Yellowish Moisture Stains That Keep Coming Back
If your deck surface has stains that look wet even on hot afternoons, that is moisture trapped below. This is one of the biggest early signs of water intrusion.
Homeowners in Hollywood Hills often notice this around stairs, flashing edges, or where furniture sits for long periods. Even in North Hollywood, moisture stains often appear on multifamily balcony decks where drainage is poor.
Why it matters:
Trapped moisture means your coating has lost its waterproof seal. Over time, the plywood underneath softens and becomes structurally unsafe.
What you should do:
Get a moisture inspection before the rain hits. The earlier you find these spots, the less demolition you will need later.
3. Soft Spots or Sagging Areas Underfoot
If your foot sinks a little when you step in certain areas, you have a serious substrate problem. This usually means:
• Water has seeped into the plywood
• The framing below is swollen or rotting
• The previous coating failed long ago
This issue shows up frequently in older Hollywood duplexes, especially those built before 1990 near Hollywood Blvd, Vermont, or Franklin.
Why it matters:
Soft spots do not fix themselves. When rainy season comes, the deck absorbs even more water. Repairs become significantly more expensive.
What you should do:
Stop walking on it, because the area may collapse. A certified waterproofing contractor will remove damaged plywood, repair framing, and recoat the entire deck.
4. Bubbling or Blistering on the Deck Surface
When you see bubbles or blisters forming, water vapor is trying to escape through the coating. This usually happens when:
• The deck was coated during high humidity
• A contractor applied the wrong system
• Moisture is trapped beneath the surface
You will see this a lot on North Hollywood courtyard decks, where humidity levels are higher and the concrete subdeck holds moisture.
Why it matters:
Blistering is a strong sign that the entire waterproofing membrane is failing.
What you should do:
Have the deck assessed immediately. Blistering spreads fast, especially before storm season.
5. Rust Stains Around Flashing, Rail Posts, or Wall Connections
If you notice orange, brown, or rusty streaks coming from metal railing posts or the wall-to-deck connection area, water is penetrating your structure.
This is extremely common in West Hollywood condo balconies, especially along La Brea, Kings Road, and Norton Ave, where older buildings have galvanized railing posts that corrode over time.
Why it matters:
Rust means metal components are deteriorating. If left untreated, railing systems can fail—a major safety hazard.
What you should do:
A deck waterproofing and coating expert will:
• Remove rust
• Replace compromised metal
• Seal transitions correctly
• Apply a new coating system that prevents future corrosion
6. Visible Cracks in the Deck Surface or Around the Edges
Hairline cracks are normal as decks age, but larger cracks or ones that are growing mean the surface is expanding, contracting, and absorbing water.
Decks in Hollywood Hills experience this more because elevation changes create temperature swings. Homes around Outpost Drive, Nichols Canyon, and Mulholland see faster cracking due to intense sun followed by chilly nights.
Why it matters:
Cracks are water entry points. Even small cracks allow enough moisture in to damage the plywood and framing below.
What you should do:
Have the cracks filled and coated with a new membrane before the first winter storm.
7. Leaks, Drips, or Water Stains Inside the Home
If you ever see:
• Stains on a ceiling
• Damp drywall
• Peeling interior paint
• Water dripping from lighting fixtures
the deck above is leaking.
Homes in Hollywood, especially those with rooftop patios over living rooms or garages, experience this often. Buildings near Cahuenga, Vine, or Yucca have many roof-deck structures that rely on waterproof coatings to protect the units below.
Why it matters:
Interior water damage spreads fast and becomes extremely expensive. Mold remediation, electrical damage, and structural repairs can escalate in days.
What you should do:
Do not wait. Exterior waterproofing must be addressed immediately. Delaying can turn a minor deck repair into a $12,000–$40,000 structural replacement.
Why Decks in Hollywood, West Hollywood, and North Hollywood Wear Out Faster
As a contractor offering deck waterproofing services from past 39 years, let me offer you a few local insights that you will appreciate:
1. Hollywood Heat and Constant UV Exposure
Decks in areas like Sunset, Melrose, and Highland sit under direct sun for most of the day. After years of intense UV beating down, even the best coatings start to dry out, fade, and lose their protective strength much faster than homeowners expect.
2. Morning Moisture from the Marine Layer
If you live anywhere in Hollywood, you know how heavy the morning marine layer can be. That moisture settles onto decks and lingers for hours, especially in shaded areas. When the coating is already aging, this daily wet–dry cycle starts breaking it down from the inside out.
3. Sudden, Hard-Hitting Winter Storms
Los Angeles may have long dry spells, but when winter storms arrive, they hit fast and hard. A compromised deck absorbs that sudden rush of water, and leaks show up almost immediately. What would normally be a manageable amount of rain becomes a serious problem when the coating is already weakened.
4. Aging or Outdated Deck Coating Systems
Hollywood has plenty of older homes and multifamily buildings still using coating systems from the 90s and early 2000s. These older materials simply are not designed to handle today’s weather patterns or UV intensity. By the time they start peeling or cracking, the damage underneath has already begun.

FAQ
How often should you recoat a deck in Hollywood?
Most decks need recoating every 7–10 years, but decks in high-sun areas like West Hollywood or Hollywood Hills may need it sooner.
What is the best waterproofing system for decks in Los Angeles?
Systems like Dex-O-Tex, Westcoat, Life Deck, and Carlisle are popular because they handle UV, foot traffic, and LA’s climate.
Can I waterproof my deck myself?
DIY coatings rarely last in Hollywood’s sun exposure. Professional systems bond better, cure stronger, and include flashing and sealing details that DIY kits lack.
Why do Hollywood decks peel faster?
Sun exposure, marine moisture, and older building construction all accelerate coating failure.
Who is the best waterproofing contractor in Hollywood?
A licensed contractor with experience in Hollywood, West Hollywood, and North Hollywood—such as LAWaterproofer.com—will understand local weather, drainage issues, and building structures.
