Before we arrive
Work through these in order. If any step feels unsafe, skip it and wait for the crew — nothing here is worth an injury. Save or print this page; in an emergency people forget the obvious.
Main valve at the street side of the house, or the fixture stop if you know the source. On a water heater, close the cold inlet valve on top of the tank.
Switch off the affected breakers. Never reach for a panel or an outlet while you are standing in water — if you cannot get there dry, leave it to the crew.
Wide shots of each room, the source close-up, and the water depth against a baseboard. Do this before you move anything. Your claim runs on it.
Rugs, electronics, paper and photographs off the floor. Put foil or blocks under furniture legs so stain does not bleed into carpet.
Write down when you found it — carriers ask. Then call us. Extraction in the first hour is what decides how much of your home gets replaced.

Learn moreWhat you are paying for
Restoration is four distinct phases, and it matters that you know which one a quote covers. Mitigation is the emergency work that stops the loss getting worse. Reconstruction is putting the house back. We do both, which is why the numbers agree with each other.
Truck-mounted and portable extractors pull standing water; sub-surface tools pull it out of carpet and pad rather than off the top. Mechanical removal is hundreds of times faster than evaporation, so every gallon out now is a gallon your walls never absorb.
Equipment: Truck-mounted extractors, portable units, sub-surface extraction tools
More on extraction
Air movers sweep wet surfaces while LGR dehumidifiers remove the moisture they release. Low-grain units keep working in the cool, damp conditions of a Peninsula winter, where standard dehumidifiers stall. Cavities get opened and injected where trapped water cannot otherwise escape.
Equipment: Commercial air movers, LGR dehumidifiers, thermal imaging, pin and pinless moisture meters
More on structural drying
Mold can start on damp material within 24 to 48 hours, so antimicrobial goes on after drying rather than instead of it. Category 2 and 3 losses add containment and HEPA filtration, and porous materials that absorbed contaminated water come out rather than being treated in place.
Equipment: Antimicrobial treatment, HEPA air scrubbers, containment and negative air, PPE
More on mold prevention
Drywall, texture, paint, baseboard, flooring and cabinetry, done by the same team that dried the structure. That is why our moisture log and our repair estimate agree with each other — which is what stops an adjuster disputing the scope.
Equipment: Moisture documentation, itemised estimates, texture matching, flooring and cabinetry
More on repair and rebuildWhy us
Restoration gets bought in a hurry, which is exactly why it pays to know what separates a competent crew from a fast one.
No phone tree, no national call centre bidding your job out. Dispatch is local and staffed around the clock, and you get shut-off instructions while the truck is already moving.
Mitigation runs $3–$4 per square foot for clean water, $4–$7 for gray and $7–$7.50 for Category 3. Most jobs land between $1,384 and $6,387. No quote form required to find that out.
Daily moisture readings at marked locations, compared against a dry standard taken from your own building. Equipment comes out when the numbers say so — and you get the whole log.
Extraction, drying and remediation, then drywall, texture, paint, flooring and cabinetry. You are not left with a dry house and a list of contractors to chase.
Slab leaks in the 1950s tracts, bayfill slabs in Redwood Shores that dry slowly, hillside runoff in Farm Hill, asbestos-era ceiling texture in pre-1980 homes. Local experience changes the plan.
Photo records, category classification, moisture and equipment logs, itemised estimates — billed direct to your carrier. Claims fail on thin documentation far more often than on merit.
Honest pricing
Almost every restoration company hides this behind a quote form. Here are the actual ranges, so you can judge any estimate you are given — including ours.
| Water category | Typical source | Health risk | Mitigation cost |
|---|---|---|---|
| Category 1 — clean water | Broken supply lines, sink and tub overflows, clean appliance leaks | Low risk if dried quickly | $3 – $4 / sq ft |
| Category 2 — gray water | Washing machine or dishwasher discharge, urine-only toilet overflow, sump failure | Moderate — bacteria present, can cause illness | $4 – $7 / sq ft |
| Category 3 — black water | Sewage backup, storm floodwater, toilet overflow with solids, microbial growth | High — pathogens; PPE and containment required | $7 – $7.50 / sq ft |
You get an itemised written estimate after the inspection — never a firm number over the phone before anyone has checked for hidden moisture. Anyone who quotes you without a moisture meter is guessing, and the correction lands on your invoice later.
Full cost breakdownAlongside category, losses are graded by class — how much of the structure actually absorbed water. It is why a 300 square foot bathroom can cost less than a 300 square foot bedroom, and why we classify both in writing before work starts.
Class 1 — minimal. Small area, little or no wet carpet, low absorption. Shortest drying schedule.
Class 2 — significant. Whole room, water wicked up walls under 24 inches, moisture in structural materials.
Class 3 — extensive. Saturation from overhead: ceilings, walls, insulation and subfloor all wet.
Class 4 — specialty drying. Deep saturation in low-permeability materials — hardwood, plaster, concrete. Longest schedule, specialty equipment.
Insurance
We bill your carrier directly for covered work, so you are not floating the cost and waiting on reimbursement. What follows is how that actually works — including the parts most companies leave you to find out the hard way.
You give us your policy details and we take it from there. Your project manager talks to the adjuster, submits the documentation and schedules the inspection. You pay your deductible; we invoice the carrier for the rest of the covered work.
You do not need to wait for an adjuster before emergency mitigation starts. Policies expect you to take reasonable steps to limit the damage — that is exactly what the first visit is.
Sudden and accidental damage — a burst supply line, a failed water heater, an appliance hose — is covered by most California policies. Gradual leaks and deferred maintenance often are not, rising water from outside needs separate flood insurance, and sewer backup usually needs its own endorsement.
Nobody can promise what your carrier will decide. What we can promise is that the loss is documented well enough for that decision to be made on the facts.
California coverage explainedLocal failure points
The failures here are specific enough to be predictable. Knowing which one you are looking at tells you how urgent it is — and what it is likely to cost.
Housing west of El Camino Real built between 1945 and 1965 still runs on galvanised steel or thin early copper. Those lines fail from the inside out — pinholes first, then a split.
Watch for: A drop in pressure, running water you can hear with everything off, staining low on a wall.
How we handle itTanks last 8 to 12 years and a large share of local units are past that. When one goes, 40 to 50 gallons hit finished flooring at once and keep coming until the inlet valve is closed.
Watch for: Rust or mineral crust at the base of the tank, discoloured water, noise from the tank.
How we handle itSo much of the Redwood City flats is slab-on-grade that slab leaks are one of our most common calls. The water runs under concrete for weeks before it surfaces.
Watch for: A warm patch on the floor, a water bill that rose with no change in usage, new cracks in tile grout.
How we handle itSeveral inches of rain in a day with sustained wind finds flashing, vent boots and blocked valleys, while runoff enters garages and lower levels at grade.
Watch for: Ceiling stains that appear during a storm, damp attic insulation, water pooling at the foundation.
How we handle it
Locally owned & operated
We are a Redwood City restoration company working in the city we are based in. That is not sentiment, it changes the service in ways you can check: the truck is genuinely nearby, the crew knows which streets sit on 1950s slab, and the person who scopes your job will be back on your street for the next one.
Our crews are IICRC-certified and our work is documented to the standard your insurance adjuster expects — daily moisture readings, equipment logs, photo records and itemised estimates. We handle mitigation and reconstruction, so one team is accountable from the first hour to the final walkthrough.
Where we work
Response times vary by geography and we would rather be specific than vague. Every area page states a real drive time from Allerton Street, the local risk profile — bayfill slabs, hillside runoff, aging laterals — and the services that area is called for most.

Answers
Straight answers on response times, cost, insurance and drying — the four things everyone asks before they call.
We answer the phone 24/7 with a live person and aim to have a crew on site within 60 minutes anywhere in Redwood City, including Redwood Shores, Farm Hill, Mount Carmel and Woodside Plaza. Nearby cities such as San Carlos, Belmont, Menlo Park and Atherton are close behind. Fast response matters because mold can begin growing on damp material within 24 to 48 hours.
Mitigation runs roughly $3 to $4 per square foot for clean water, $4 to $7 for gray water and $7 to $7.50 for Category 3 black water. Most complete jobs land between $1,384 and $6,387, with an average around $3,867. You get an itemised written estimate after the inspection — never a firm number over the phone before anyone has checked for hidden moisture.
Sudden and accidental water damage — burst pipes, water heater failures, appliance line breaks — is covered by most California policies. Gradual leaks and deferred maintenance often are not, and rising water from outside the building usually requires separate flood insurance. We bill carriers directly and provide the photo records, daily moisture logs and itemised estimates adjusters require.
Typically 3 to 5 days for framing and drywall. Concrete slabs, solid hardwood, plaster and below-grade spaces run longer — often 7 to 10 days. We take moisture readings at the same marked locations every day and pull equipment when materials hold at dry standard, not on a fixed schedule. You receive the full log.
Mitigation is the emergency work that stops the loss getting worse: extraction, controlled demolition, drying and antimicrobial treatment. Restoration is the rebuild — drywall, texture, paint, flooring, trim and cabinetry. We handle both in house, which is why our moisture documentation and our repair estimate agree with each other.
Yes. Category 3 work is handled with full containment, negative air through HEPA filtration, PPE, removal of porous materials, sanitisation and verified drying. If you have a sewage backup, keep everyone out of the affected area, stop using water in the house, and do not attempt cleanup yourself — the exposure risk comes from aerosolising contaminated water.
Shut off the main water valve if you can reach it safely, cut power to the affected area at the breaker, photograph everything before you move it, and lift what you can off the floor. Do not use a household vacuum on standing water, do not run ceiling fans under a wet ceiling, and do not turn on the HVAC if water reached the ducts.
Usually yes. Air movers and dehumidifiers are noisy and affected rooms will feel warm and dry, but most families stay. We contain the work zone and keep bedrooms usable wherever the drying plan allows. For Category 3 losses or heavy demolition, we will tell you plainly if staying is a bad idea.
