Wind-Driven Rain and Where It Gets In
El Monte uses a design wind speed of 95 miles per hour as a three second gust, at Exposure B. That number matters more for waterproofing than people expect. Rain falling straight down is easy to shed. Rain pushed sideways at speed goes uphill into laps, under flashing, behind a railing post and through the gap at a door threshold.
So the parts of the job we take most seriously are the ones you cannot see afterward: how the membrane turns up a wall, how it terminates at a threshold, and how it is sealed around anything that penetrates the deck.
The city sits between the San Gabriel and Rio Hondo rivers, and around 60 percent of occupied housing is rented. A large share of the work is walkways, stairs and balconies on multi unit buildings, where a single bad termination feeds water to several units at once.
Guardrails matter here for the same reason. A design gust is a load on the rail and on every anchor holding it down, and each of those anchors is a hole through a waterproof surface. Those get flashed and sealed, not just tightened.
We fabricate the steel in our own shop, so a stair stringer that has rusted through at its concrete base gets replaced rather than braced, and a guardrail that has lost section gets remade instead of wire brushed and painted.

Waterproofing in El Monte: Your Questions
What does a wind speed have to do with a leaking balcony?
El Monte designs to a 95 mph three second gust at Exposure B. Wind at that speed drives rain sideways and upward, so water gets under flashing and into laps that would never leak from rain falling straight down.
Do you work on apartment buildings in El Monte?
A lot of it. Around 60 percent of occupied housing here is rented, so shared walkways, open stairs and stacked balconies make up much of what we repair, and we stage the work to keep residents moving.
Where do these decks usually start leaking?
At the edges, not the middle. The wall junction, the door threshold and every railing post or drain that punches through the surface. That is where we cut in and look first.
