Water rarely enters where the stain appears. The usual suspects are the door pan, the flashing where the deck meets the wall, or a blocked drain — then it travels along framing before it shows.
Deck & balcony waterproofingRepeat failure is a question about what is underneath. Trapped moisture, a substrate that was never dried or repaired, or a new product incompatible with the old system will all push a coating back off.
Deck & balcony waterproofingSlope, drains and scuppers decide where water goes. A surface that holds water puts the coating under constant load and finds every weak seam.
Deck & balcony waterproofingThat powder is efflorescence — salts left behind as water passes through masonry. It means moisture is moving through the wall, not just sitting on it.
Below-grade waterproofingA planter holds wet soil directly against the structure. When the membrane, the drainage or the transition to the deck fails, the water has nowhere to go but inward.
Planter waterproofingStucco drains water down a barrier behind it and out at the weep screed. Interrupt that path at a deck-to-wall joint or a buried screed and moisture stays in the wall.
Stucco & deck-to-wall repairs
Balconies & decksWhy a balcony leaks around the doorThe threshold is where a horizontal surface meets a vertical wall and an opening, all at once. Get the pan, the flashing and the laps in the wrong order and water walks straight in under the door.Read the full breakdown 
PlantersA built-in planter is a pond with soil in itSoil stays wet long after the rain. Without a membrane carried up the walls, a working drain and a sealed transition to the deck, that water ends up in the room below.Read the full breakdown 
StuccoStucco cracks are usually a drainage storyStucco is designed to let water through and drain it out at the weep screed. Patching the crack without restoring that path just moves the problem.Read the full breakdown 
Pool decksPool decks take the worst of itConstant wet traffic, sun and salt air, often over enclosed space. The walking surface is the part you see; the assembly underneath decides whether it lasts.Read the full breakdown 
LA Waterproofer has protected Southern California properties from water damage since 1986. The company was founded by Darren Elliott and works on residential, commercial and multi-family buildings across Los Angeles and Ventura counties.
Whether it is a rooftop deck in Malibu, a below-grade garage in Los Angeles or a planter in Ventura, the approach is the same: find where water is actually getting in, then specify a repair that addresses it rather than covering it.

The things homeowners ask us most often, before any work is quoted.
No. Estimates for proposed repair work are free and include a written description of the work and the price.
We work across Los Angeles and Ventura counties, including Malibu, Santa Monica, Pacific Palisades, West Los Angeles, Beverly Hills, West Hollywood, Hollywood, Culver City, Playa del Rey, Pasadena, Calabasas, Agoura Hills, Hidden Hills and Santa Clarita.
A deck is an assembly, not just a surface. Water often enters at a door pan, a deck-to-wall connection, a flashing detail or a blocked drain, then travels before it shows up inside. That is why a stain on a ceiling rarely sits directly below the point where water got in.
Sometimes. Recoating suits a sound assembly where the surface can be properly prepared and the new material is compatible with what is already there. If the substrate is damaged, or the leak is coming from flashing, a doorway or drainage, another coating will leave that cause in place.
Project timing depends on the repair scope, access, weather and material requirements. We discuss the expected schedule for your project before work begins.
