Frequently Asked Questions

The tide mark is the line water leaves on a wall as it rises and recedes. It's the first thing a restoration tech looks for because it shows exactly how high the water reached, which tells us where to cut, where to dry, and where hidden moisture is likely sitting. Drying only the visible wet spot misses everything below the tide mark. That's why we say we find the tide mark and dry past it. In San Francisco homes built on hillsides, water doesn't always sit level, so reading the tide mark correctly matters even more. It's a small detail that prevents mold and rot months later.

First, we stop the water and map the damage. Then we remove standing water, pull out saturated materials that can't be saved, and set up drying equipment like air movers and dehumidifiers. We monitor moisture levels daily until readings show the structure is dry past the tide mark. Finally, we clean and sanitize the area and give you a photo of the cleanup before we leave. Every step follows the C.A.R.E. code: we clean up like it's our own home, ask before we move or touch anything, respect your family's time and quiet hours, and explain the price before the work.

Most residential jobs take 3 to 7 days from water shutoff to final dry-out confirmation. The drying phase alone is usually 2 to 4 days, but San Francisco's coastal humidity can stretch that in older homes with dense plaster or double-wall construction. Demolition happens on day one, drying runs continuously after that, and we check moisture readings until they're stable. Rebuild and finish work like drywall replacement, paint, and flooring is a separate phase scheduled after the structure is dry. You'll get a timeline in writing with the estimate so you can plan around it.

Usually not. For most water damage jobs in San Francisco, you can stay in the home while drying equipment runs. The equipment hums at a low, steady level, and we respect quiet hours if kids are napping or you're working from home. If the damage is extensive like sewage backup or wide area flooding that requires full-floor demolition, you may want to relocate for a few days while the worst of the work happens. We'll tell you honestly what to expect and when it makes sense to stay elsewhere. The decision is yours, and we'll work around your family's schedule where we can.

We put down shoe covers and drop cloths inside the house before any equipment or materials come through the door. Furniture that stays in place gets covered or moved with your permission. We ask before we move or touch anything, which is part of the C.A.R.E. code we work by. If pets are in the home, we use pet-safe products where there's a choice, and we'll tell you which products we're using before we use them. Before we leave, we photograph the cleanup so you can see the standard we held ourselves to. Clean floors and safe air are how we judge our own work.

We run Injectidry systems for hard-to-dry cavities and subfloor spaces, paired with commercial dehumidifiers and air movers matched to the size of the affected area. Injectidry is the standard we trust for pulling moisture out of spaces that standard fans can't reach, like wall cavities, under cabinets, and beneath hardwood floors. Our techs are trained to place and monitor the equipment until moisture readings confirm the structure is dry past the tide mark. For San Francisco's older homes with lath and plaster and dense old-growth framing, the right equipment makes the difference between a thorough dry-out and a mold problem six months later.

Our team follows the standards set by the IICRC, the Institute of Inspection, Cleaning and Restoration Certification, which is the recognized authority for water damage restoration practices. We hold ourselves to those protocols on every job: proper dry-out targets, correct equipment sizing, and sanitization standards. When you're comparing restoration companies in San Francisco, asking about IICRC standards is a smart question. It means the crew understands moisture science, not just how to run a Shop-Vac. Rick Sumner leads a team that trains to these standards and applies them to every home we enter.

We work within the framework of the RIA, the Restoration Industry Association, and follow IICRC protocols. These organizations set expectations for how restoration work should be performed, documented, and verified. For a San Francisco homeowner, that means the crew in your house is working to a national standard, not improvising. We're part of the Tidemark Water Damage Restoration family, which means our local team operates independently but holds to the same Cedarwell Care Promise as every other location. Ask us anything about our process and we'll explain it in plain language.

Yes. Every professional working under our name is required to hold the license and insurance their state requires, and our San Francisco operation carries the coverage needed for residential restoration work. We're happy to provide proof of insurance when you schedule the job, and most homeowners request it, which we expect and welcome. If you're filing an insurance claim, our documentation standards help the adjuster process your claim faster. Ask for our insurance certificate when we walk the site, and we'll have it ready. Call (831) 400-3496 to talk through the details.

Look for written pricing before work starts, documented moisture readings, and a crew that treats your home like a living space, not a job site. Ask if they follow IICRC standards and what equipment they run. Ask what happens if the drying isn't complete, and get the answer in writing. Ask who documents the damage for your insurance company. In San Francisco specifically, ask if they have experience with older construction, because Victorian and Edwardian homes dry differently than 1990s drywall builds. And trust your gut on how the estimator talks to you. If they're vague about price or process, keep looking.

Yes, we coordinate directly with your adjuster. We provide photo documentation of the damage before, during, and after cleanup, along with moisture readings and a clear scope of work. That paper trail helps the adjuster understand exactly what happened and what it took to fix it, which usually moves the claim along faster. You don't need to be the middleman translating technical restoration talk to your insurance company. We'll send you the same documentation we send them so you always know what's being said about your home. Call (831) 400-3496 and we'll walk through what to send your carrier.

If you call during our operating hours, we'll get you scheduled as soon as possible. Our hours are Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. We're closed on Saturdays. When you call (831) 400-3496, a live coordinator answers and connects you with our local San Francisco team. For a burst pipe or active leak, the most important thing you can do right away is shut off the water at the main valve if you can do so safely. Standing water left overnight in San Francisco's cool, damp air starts affecting materials immediately.

Shut off the water at the main valve if you can find it and reach it safely. Most San Francisco homes have the main shutoff near the street or in the garage. Move electronics, documents, and anything valuable off the wet floor if it's safe to walk. Turn off electricity to the affected area at the breaker if water is near outlets or appliances, but don't step into standing water to do it. Open windows if the outside air is dry, though in San Francisco fog that may not help much. Then call us at (831) 400-3496 and describe what you see. We'll tell you what to do next.

Every city has its patterns, and San Francisco's are shaped by the marine layer and the age of the housing stock. Fog-heavy neighborhoods like the Sunset, Richmond, and Ingleside see slower natural drying, which gives hidden moisture more time to do damage. Many homes built before 1950 have plaster walls that wick water upward quickly but dry slowly. Galvanized supply pipes in older buildings fail with age, and we regularly see leaks in homes where the original plumbing is still in place. Knowing the house you're dealing with before you buy is wise. If you've had a leak or a loss, we'll map it and dry it past the tide mark properly.

The Cedarwell Care Promise is the guarantee every Tidemark location works to. It's shoe covers and drop cloths inside the house, quiet tools when the kids are asleep, pet-safe products where there's a choice, a photo of the cleanup before we leave, and a written price before any work starts. It's the standard we hold ourselves to on every job, not a marketing line. Rick Sumner and our San Francisco team chose to operate under this promise because it matches how we'd want someone treating our own homes. If the cleanup isn't right, we'll make it right. That's what the promise means.

Our work is covered by the Cedarwell Care Promise, and we document the dry-out with moisture readings so you know the job is actually done before we pack up the equipment. If something isn't right with the cleanup or the dry-out, tell us and we'll address it. Restoration work has variables because water is unpredictable, which is exactly why we monitor moisture daily until readings are stable and show you the data. The written scope and the photo documentation are your record of what was done and to what standard. Ask us to walk you through the readings before we leave and you'll see it for yourself.

If we dried the structure properly and the moisture source was fully stopped, mold should not appear. That's the standard we work to. If you do see discoloration or smell something musty in the months after a job, call us and we'll come inspect. Sometimes what looks like mold is staining or dust, and we'll tell you honestly which it is. In the rare case where moisture was trapped somewhere we couldn't reach and mold did develop, our team will assess it and recommend the right next step. San Francisco's damp air means mold concerns should be taken seriously, and we don't dismiss them. Call (831) 400-3496 if you're worried.

For small spills like a glass of water or a minor sink overflow, a towel and a fan might be enough if you catch it immediately. But for anything that soaked into drywall, flooring, or baseboards, DIY drying is risky. The water spreads laterally and upward into wall cavities where you can't see it, and San Francisco's slow-drying conditions give mold a head start. A shop fan on the surface dries the visible part while hidden moisture stays trapped. By the time you see staining or smell something, the damage is deeper. A free on-site inspection from a pro lets you know honestly whether you need equipment or just time and open windows. Call (831) 400-3496 for that honest read.

Sometimes, if the water was clean and caught fast. A supply-line leak caught on day one in a modern home might dry in place with Injectidry systems pulling moisture from the wall cavity without cutting drywall. But if the water was contaminated, like sewage backup or a dishwasher leak that soaked through particle board, or if materials were wet for days before discovery, demolition is usually the right call. Wet drywall and saturated underlayment become a mold food source, and San Francisco's humidity doesn't help. We'll tell you what's really needed and what's not. The written scope explains exactly what gets removed and why, so you're not watching a crew cut more than necessary.

We schedule estimates during our regular hours: Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. When you call (831) 400-3496, a live coordinator picks up and finds the soonest opening for our San Francisco team. The estimate is free, and you'll get a written scope and price before any work begins. For active leaks or standing water, don't wait. Call right away, and we'll get the process moving. Rick Sumner and our local crew know the neighborhoods, the construction types, and the weather patterns that affect drying times here. We're ready to help.

Yes. Our service area includes San Francisco and the surrounding East Bay and Peninsula communities: Oakland, Hayward, Berkeley, Piedmont, Vallejo, Richmond, Daly City, San Mateo, San Leandro, Walnut Creek, and Alameda. Each city has its own housing stock and moisture patterns, and our team is familiar with all of them. Whether your home is a 1920s craftsman in Berkeley or a mid-century build in San Leandro, we'll adapt the drying plan to the structure. Call (831) 400-3496 and our coordinator will confirm availability for your area.
