Storm damage restoration in Altadena typically runs between $1,800 and $6,500 for most single-family homes, depending on how far water traveled through plaster walls, flooring, and crawl spaces. Wind-driven rain and chimney leaks are the two most common calls we get from Altadena homeowners between November and March. Our crews reach most Altadena neighborhoods within 45 to 60 minutes of your call, because dispatch is coordinated from the brand’s Los Angeles office and we keep local equipment staged for foothill response. If you’re standing in water or watching it spread behind a wall, call (626) 657-5106 now and a live person will answer.
Fast, Reliable Storm Damage Restoration Across Altadena
When a storm hits Altadena, the damage rarely announces itself all at once. Rain driven by Santa Ana winds finds its way through cracked chimney chases, old wood windows, and unsealed rooflines, then sits inside plaster and lath walls where you can’t see it. That’s the kind of damage we map, dry, and repair before mold ever gets a foothold. We know the difference between a 1920s Craftsman bungalow off Lake Avenue and a 1950s ranch near Loma Alta Park, because the building methods change how water moves and where it hides. Our Storm Damage Restoration crew has been working in Altadena long enough to know which streets flood first, which chimneys crack in seismic events, and which garages and workshops have the worst air sealing. Call (626) 657-5106 and we’ll send a technician to Altadena today.
Restoration work we handle






Why Marsh Water Damage Pasadena Is Altadena’s Preferred Storm Damage Restoration Company
Altadena homeowners call us because we show up with a plan, a written price, and a technician whose name and photo you already have before the truck parks. The Threshold Verified standard is not a slogan here. Every tech is background-checked, identity-verified, uniformed, and photo-badged, and that badge gets shown at your door before a single piece of equipment crosses the threshold. Led by Tobias Reyner, our team treats every Altadena job like the structure’s age and materials demand: with moisture mapping on plaster walls, circuit checks on knob-and-tube wiring, and drying logs kept on every detached workshop and garage. A written price is agreed before work starts, and every repair carries our 365-Day Done Right Promise, which means if something is not right within a full year, we come back and make it right at no charge. That promise is printed on the work order, not whispered as a sales line.
Storm Damage Cleanup in Altadena
Storm Damage Cleanup in Altadena means extracting standing water, removing storm-soaked materials that can’t be dried, and setting professional drying equipment before hidden moisture turns into mold inside wall cavities and under hardwood floors. On a typical Altadena home, storm damage cleanup runs $1,200 to $3,800 before any reconstruction, depending on how many rooms were affected and whether crawl spaces or detached structures are involved. Foothill properties north of Altadena Drive often have longer driveways and detached workshops, which changes equipment staging and sometimes requires an extra air mover or dehumidifier. We bring commercial drying gear from Dri-Eaz and XPOWER, not rental-store fans, so the drying happens in days, not weeks.
Water Extraction and Structural Drying
Storm water gets extracted with truck-mounted or portable extraction units, then the drying plan begins. In Altadena homes with original plaster and lath, we take moisture readings (psychrometric readings, which measure the moisture in the air and inside wall cavities) at multiple depths, because the surface can be dry while the cavity behind it is still saturated. Drying logs are kept for every affected area, including crawl spaces and detached garages, so no hidden pocket gets missed.
Containment and Antimicrobial Treatment
When storm water saturates drywall, insulation, or wood siding, we contain the area to prevent cross-contamination of unaffected rooms. Affected materials that cannot be salvaged, like category 2 water-damaged wood siding or soaked insulation, get removed and bagged. Then we apply antimicrobial treatment to framing and wall cavities before reconstruction begins, which is critical in Altadena’s older homes where organic building materials give mold plenty to feed on.
Flood Cleanup in Altadena
Flood Cleanup in Altadena is different from a slow leak, because floodwater is often contaminated and moves fast through low-lying rooms, crawl spaces, and floor systems. Most single-family flood cleanup jobs in Altadena run $2,200 to $6,500, with black water jobs (septic field flooding, backed-up drains) landing higher due to contamination protocols and disposal requirements. Mid-century Altadena homes with original hardwood floors, often found south of New York Drive and near Farnsworth Park, need rapid extraction to prevent cupping and warping that cannot be reversed once the wood has been wet more than 48 hours. We treat every flood as a structure-wide event, not just a wet patch on the floor.
Black Water and Sewage Backups
If a flooded septic field or a backed-up drain has pushed black water into an Altadena home, this is a category 3 water loss and requires full PPE, containment, and controlled disposal. We remove the contaminated water, cut out affected drywall and flooring, and disinfect the entire area with professional antimicrobial agents before drying begins. This is not a job for a shop vac and a weekend, and anyone who tells you otherwise is putting your family at risk.
Crawl Space and Foundation Flooding
Many Altadena homes sit over crawl spaces that flood during heavy winter rain, especially on flatter lots south of the foothills where drainage is slow. Standing water in a crawl space raises indoor humidity, warps hardwood floors above, and invites mold into the floor system. We pump, extract, and dry crawl spaces with high-volume air movers and dehumidifiers, then log every reading so you can see the humidity dropping day by day.
Trusted Brands We Service in Altadena
If your Altadena home has equipment from Dri-Eaz, Phoenix, or XPOWER already on site, we service and operate those same brands, along with our own fleet of commercial drying tools. That matters because the gear in your garage or workshop tells us a lot about how your property has been dried before, and whether previous drying jobs left moisture behind. We keep common replacement filters, hoses, and dehumidifier parts stocked for fast turnaround on Altadena jobs, so a failed component does not stall a drying plan for days. Our technicians hold IICRC, RIA, and IFA credentials, and they know these machines cold, from the LGR dehumidifiers to the low-profile air movers that fit under raised foundations.

AfterCommon Storm Damage Restoration Problems We See in Altadena Homes
- Hidden water behind plaster and lath walls: Storm water enters through cracked chimneys or old windows and travels inside the wall cavity, where the plaster surface looks dry for weeks. We moisture-map every affected wall, because surface readings alone miss what is happening behind the plaster in Altadena’s 1920s to 1950s homes.
- Knob-and-tube wiring inside wet wall cavities: Many Altadena homes still have original knob-and-tube wiring, and when water reaches those circuits, you now have a shock and fire hazard. Before we plug in dehumidifiers and air movers on affected circuits, we check what is live and what needs to be isolated.
- Unreinforced masonry chimneys that crack and leak: In the foothill neighborhoods north of Altadena Drive, seismic events have left hairline cracks in masonry chimneys that funnel winter rain straight behind the firebox and into floor systems. A generalist sees a chimney and calls it solid; we inspect and moisture-map around it every time.
- Detached workshops and garages with poor air sealing: Storm water pools against altadena outbuildings, and because these structures often lack proper air sealing, they dry unevenly and hide moisture in subfloors. We run drying logs on every detached structure, not just the main house.
Pricing for Storm Damage Restoration in Altadena, CA
Most residential storm damage restoration jobs in Altadena land between $1,800 and $6,500. A straightforward water extraction with a few days of drying equipment runs $1,200 to $2,800. Flood cleanup with contaminated water and material removal sits higher, from $2,200 to $6,500. The biggest cost drivers are the number of affected rooms, whether the crawl space or detached structures are involved, and whether plaster walls need to be opened for drying or left in place with targeted injection drying. We give every Altadena customer a written price before any work starts, and that number does not change after demo begins. Call (626) 657-5106 for a free, no-pressure estimate.

FAQs About Storm Damage Restoration in Altadena
We moisture-map the wall cavities at multiple depths, because plaster and lath dries unevenly and the surface can read dry while the interior is still soaked. In a 1940s ranch off New York Drive, our techs arrived after a Santa Ana wind event had driven rain through a cracked chimney chase. Using a Dri-Eaz LGR dehumidifier and XPOWER air movers, we set containment, logged moisture readings across plaster and lath, and removed category 2 water-damaged wood siding before antimicrobial treatment, restoring the wall to pre-loss condition in one trip. That is the standard we apply to every plaster-wall home in Altadena. Call (626) 657-5106 if you suspect water behind your plaster.
Yes, we plan every Altadena job for one trip when possible, including the driveway conditions and the outbuildings. Before a pack-out is authorized, we scope the gravel driveway so the mover’s truck does not sink during wet season, because that single oversight delays the entire mitigation schedule. We bring enough equipment, containment, and drying capacity on the first truck to handle the house, the detached workshop, and the garage in one visit. Call (626) 657-5106 and we will walk you through the plan before the truck leaves.
Treat the wiring as live until proven otherwise, and do not plug in fans or dehumidifiers on any affected circuit. We check what is live and what needs to be isolated before any drying equipment is connected, because knob-and-tube wiring inside wet wall cavities creates a shock and fire risk. In Altadena’s older Craftsman homes, this is one of the first things we assess on arrival. Call (626) 657-5106 and we will send a technician who knows exactly what to look for.
Black water is a category 3 loss, which means full containment, PPE, and controlled disposal, not just extraction and drying. We remove the contaminated water, cut out soaked drywall and flooring, disinfect the area with professional antimicrobial agents, and then begin structural drying. Mid-century Altadena homes with original hardwood floors need this done fast, because once black water penetrates the wood for more than 48 hours, the flooring typically cannot be saved. Call (626) 657-5106 immediately; this is not a job to delay.
Because in the foothill neighborhoods north of Altadena Drive, many homes still have unreinforced masonry chimneys that crack during seismic events, and those hairline cracks channel rainwater behind the firebox and into floor systems all winter. The chimney looks solid from the outside, but water is entering behind it and traveling through wall cavities and subflooring where no one is looking. We inspect and moisture-map around every chimney on every storm damage job in Altadena, because this is one of the most common hidden damage sources in this city. Call (626) 657-5106 for a free inspection if you suspect a leak near your chimney.
