Granada Hills runs north from the valley floor into the Santa Susana Mountains, and it gains real elevation doing it. The southern half is conventional postwar tract housing; the northern half is larger lots, sloping ground, equestrian zoning in places and properties tucked against the foothills.
The 1994 earthquake hit here hard — the Balboa Boulevard gas line ruptures and the fire that followed are among the most-photographed images of that event — and a meaningful share of local housing was repaired or rebuilt in the years after.
Restoration work here divides between slope drainage in the north and slab plumbing across the south, with the post-1994 mixed construction complicating both.

Slope, and the two kinds of water it delivers
On sloped ground water reaches a foundation two different ways, and homeowners routinely fix one while staying exposed to the other.
Surface water is what you see — running down a driveway, sheeting off a slope, overflowing a blocked area drain. It arrives during the storm and responds to grading, drains and downspout discharge.
Subsurface water is different. Rain percolates into the slope above and travels laterally through the soil until it meets something less permeable, frequently your foundation, arriving a day or more after the rain stopped. No amount of surface grading affects it; interception uphill does. The tell is timing — water appearing on a clear day two days after a storm is subsurface, and efflorescence on a foundation wall maps where it's been moving.
Crawl spaces and outbuildings on the northern lots
Raised foundations are more common on the sloping northern lots than on the valley flat, and a sloped crawl space is shallow on the uphill side and generous on the downhill side. Water entering uphill runs the length of the space and ponds at the low end, evaporating into the floor structure above for weeks.
That's fixable and worth fixing. A raised foundation gives us access — pump it out, dry the soil surface and framing, install a proper vapor barrier, correct the drainage at the uphill wall. It's a well-defined project with a permanent result, which is more than you can say for the same water under a slab.
Larger lots also mean outbuildings — barns, workshops, detached garages — that sit lower and drier-built than the residence. They flood first, hold water longest, and frequently contain the contents people actually care about.
Mixed construction and slab plumbing
Across the southern tracts the year-round problem is the standard postwar one: copper supply lines run through concrete slabs, sixty-plus years old, abrading through where the pipe contacts the slab. Hot-water lines fail first.
The post-1994 repair history complicates it. Where a line was rerouted overhead during reconstruction rather than replaced in the slab, a failure may present in an attic or a wall rather than under the floor — so we map rather than assume. And a house that is partly original and partly rebuilt contains both eras of material behind the same finishes.
We locate slab leaks with thermal imaging and acoustic equipment before anyone opens concrete, then map how far moisture has spread — which is usually further than the warm spot suggests, because water under a slab wicks up into wall plates across several rooms.
Local risk profile
What causes water damage in Granada Hills
Lateral subsurface flow on northern slopes
Water percolating into the hillside arrives at uphill foundation walls days after rainfall, unaffected by surface grading.
Sloped crawl spaces that pond at the low end
Water entering uphill collects downhill and evaporates into the floor structure for weeks after a storm.
Mixed original and post-1994 construction
Rebuilt sections mean rerouted plumbing and unpredictable moisture paths behind the same walls.
Outbuildings on larger lots
Barns, workshops and detached garages flood before the residence and hold high-value contents.

Why us, here
Why Granada Hills residents call Drycore Restore
Surface and subsurface separated
Northern slopes deliver both. Homeowners routinely fix drains and stay exposed to lateral flow arriving two days later.
Sloped crawl spaces get fixed properly
Shallow uphill, generous downhill, ponding at the low end. Pump, dry, treat, vapour barrier, correct the uphill drainage — a defined permanent result.
Post-1994 rebuilds change the map
Rerouted plumbing behind rebuilt sections makes moisture paths unpredictable, so we meter rather than infer.
What Granada Hills calls sound like
North of Chatsworth Street the ground does the work. Most Granada Hills winter calls up there are subsurface flow, not anything running inside the house.

Both. The same crew that extracts and dries also installs the new drywall, matches texture, paints, and reinstalls trim, flooring and cabinetry — so the job actually finishes instead of stalling between two contractors.
