Understanding Water Damage
Not all water damage is the same. The category of water determines contamination protocols, equipment requirements, and what the insurance carrier will approve for removal versus drying in place. Getting this wrong costs money, and can create liability.
Originates from a sanitary source with no substantial risk of causing sickness or discomfort. Materials affected by Category 1 water can often be dried in place if addressed quickly, before contamination or microbial growth occurs.
Common Sources
Supply line breaks · Sink overflows (clean) · Toilet tank leaks · Rain intrusion · Refrigerator lines · Water heater failures
Contains significant contamination with potential to cause discomfort or sickness if contacted. Category 2 requires stricter protocols, affected porous materials often cannot be dried in place and must be removed. Category 1 that sits more than 24–48 hours becomes Category 2.
Common Sources
Washing machine overflow · Dishwasher discharge · Toilet overflow (no feces) · Sump pump failure · Aquarium leaks · HVAC condensate
Grossly contaminated, contains pathogenic agents. All affected porous materials must be removed. No exceptions. Category 3 requires full PPE, containment, and antimicrobial treatment. Category 2 that is not remediated within 48–72 hours becomes Category 3.
Common Sources
Sewage backup · Toilet overflow with feces · Rising flood water · River or stream intrusion · Wind-driven rain through structural breach
Drying Complexity
Class determines how much moisture has been absorbed and how difficult drying will be. It directly affects the amount of equipment required, drying time, and the defensibility of your Xactimate scope. Misclassifying class is one of the most common ways carriers underpay claims.
Least amount of water absorbed. Damage is limited to a partial room, or materials with low porosity. Carpets may be wet but pad is not saturated. Structural materials show minimal absorption.
Typical Dry Time: 2–3 Days
Entire room affected. Carpet and pad saturated. Water has wicked up walls 12–24 inches. Structural materials absorb significant moisture. Requires higher equipment density and daily monitoring.
Typical Dry Time: 3–5 Days
Greatest amount of water absorbed. Water may have come from overhead, ceilings, walls, and insulation are saturated. Requires maximum equipment deployment and often cavity drying systems.
Typical Dry Time: 5–7 Days
Involves materials with very low porosity, hardwood, concrete, plaster, brick, stone. Requires specialty drying equipment and significantly longer drying time. Standard air movers and dehumidifiers are insufficient.
Typical Dry Time: 14–21+ Days
Immediate Action Guide
The decisions made in the first hour after a water loss directly affect the final claim amount, restoration timeline, and whether secondary damage occurs. Most mistakes are made before the contractor arrives.

Our Process
Every phase of water damage recovery handled by one licensed, independent crew, from same-day extraction through certificate of occupancy. ACH-calibrated equipment, daily moisture logs, and insurance-defensible documentation at every step.
Same-day water extraction using truck-mounted and portable units. Category and class assessment, source identification, and containment to stop secondary migration before it compounds the loss.
Infrared thermal imaging pinpoints hidden moisture behind walls, under flooring, and inside cavities. Every affected area mapped and documented before drying begins, no guesswork, no missed pockets.
3D laser scanning captures the full loss environment with dimensional accuracy. Combined with Xactimate line-item scoping, this produces insurance-defensible documentation that holds up to adjuster and public adjuster review.
Commercial generator deployment ensures continuous power to drying equipment on sites with damaged electrical systems or insufficient load capacity. Equipment keeps running, drying never stops due to power constraints.
ACH-calibrated air movers and dehumidifiers placed to engineering spec. Daily moisture readings, drying logs, and psychrometric data documented through every cycle until structure reaches dry standard per IICRC S500.
Industrial desiccant units deployed for deep structural drying in high-humidity conditions, cold environments, and large commercial spaces where refrigerant units can't achieve required grain depression.
Licensed GC crew handles full structural reconstruction after confirmed dry standard, framing, drywall, flooring, mechanical, and finish work. Single point of contact from water extraction through certificate of occupancy.

Industry Truth
One of the most damaging misconceptions in water damage restoration, and one that costs property owners thousands of dollars in underpaid claims and hidden mold remediation costs down the road.
You've heard it from adjusters, TPA vendors, and program contractors: "Standard water damage dries in three days. We'll pull the equipment on day three."
This is not an industry standard. It is a cost-containment strategy. There is no IICRC standard, no S500 provision, and no scientific basis for a blanket 72-hour drying claim, and yet it is used routinely to justify pulling equipment before dry standard is reached and reducing Xactimate scope line items.
The result: moisture stays trapped in walls, subfloor, and framing. Within weeks, mold growth begins. The cost to remediate secondary mold from a prematurely closed water claim is almost always higher than the equipment rental that was "saved."
IICRC S500 is clear: drying is complete when materials reach acceptable moisture content levels as verified by daily psychrometric readings and moisture mapping, not by the calendar.
Class 1 losses in ideal conditions can reach dry standard in 2–3 days. Class 3 losses with saturated ceilings, walls, and insulation routinely take 5–7 days. Class 4 losses involving hardwood, concrete, or plaster require 14–21+ days and specialty drying equipment.
JH Construction documents every reading, every day, until dry standard is confirmed. Our drying logs are Xactimate-formatted and built to defend against carriers who try to reduce scope by invoking the 72-hour myth. We don't pull equipment until the structure is actually dry.
Why JH Construction
Most water losses get worse while people wait, for a carrier to approve, for a TPA to dispatch, for a program vendor to show up with undersized equipment. JH Construction arrives same-day, places equipment to IICRC spec, documents every reading, and doesn't pull equipment until the structure is confirmed dry.
Water gets worse every hour. We dispatch same-day across all three Northern California regions, extraction starts before secondary damage compounds the loss.
All water damage restoration follows IICRC S500, equipment placement, drying targets, and documentation that insurance carriers accept without dispute.
Every drying cycle documented with psychrometric readings, moisture maps, and equipment logs. Built to defend against carrier scope reductions.
No TPA program. No franchise. No preferred vendor restrictions. We work for the property owner, fully licensed CSLB#929897, fully accountable.
Frequently Asked Questions
Answers to the most common questions from property owners, asset managers, and adjusters after a water loss in Northern California.
JH Construction responds same-day to water damage across all of Northern California. We serve the Bay Area, Central Valley (Tracy, Stockton, Modesto), and Sacramento regions. Water damage worsens every hour, our crews arrive with extraction equipment, thermal imaging, and drying gear to stop secondary damage before it compounds the loss. CSLB#929897.
There is no IICRC standard requiring water damage to dry in 72 hours. The "3-day drying" claim is a carrier cost-containment strategy used to justify pulling equipment before dry standard is reached. Class 3 losses routinely take 5–7 days. Class 4 losses involving concrete, hardwood, or plaster take 14–21+ days. Pulling equipment early leaves moisture trapped in walls and framing, leading to mold growth that costs more to remediate than the equipment rental that was "saved." JH Construction doesn't pull equipment until IICRC dry standard is confirmed with daily psychrometric documentation.
Category 1 is clean water from sanitary sources. Category 2 (grey water) contains significant contamination. Category 3 (black water) is grossly contaminated from sewage or flooding. Category determines whether materials can be dried in place or must be removed, which directly affects your insurance scope. Category 1 that sits more than 24–48 hours becomes Category 2. JH Construction documents category accurately in Xactimate to ensure full coverage.
Class 1 involves minimal absorption in a partial area, typically 2–3 days to dry. Class 2 affects an entire room with carpet and pad saturation: 3–5 days. Class 3 involves overhead saturation of ceilings, walls, and insulation: 5–7 days. Class 4 involves specialty materials like hardwood, concrete, and plaster: 14–21+ days requiring specialized drying equipment. Misclassifying class is one of the most common ways carriers underpay water damage claims.
Yes, commercial and multifamily water damage restoration is JH Construction's core vertical in Northern California. We handle burst pipes, slab leaks, roof failures, and large-loss CAT water events at apartment complexes, hotels, and commercial buildings. We use dry-in-place methodology to minimize tenant displacement and provide Xactimate documentation by unit for insurance adjusters. CSLB#929897.
Dry-in-place means drying the structure without removing walls, flooring, or ceilings unless absolutely necessary. JH Construction uses injection drying systems, floor mat systems, and wall cavity attachments. This reduces costs, minimizes tenant displacement, accelerates timelines, and reduces the overall claim size, benefiting both the property owner and the carrier.
Yes. JH Construction works with all major carriers and adjusters on water damage claims across Northern California. We write Xactimate scopes with daily moisture logs, psychrometric documentation, and 3D scanning data. We communicate directly with carriers to resolve scope disputes so you never play middleman between your contractor and your insurance company. CSLB#929897.
Costs vary based on category, class, property type, structural penetration, and reconstruction required. Minor Category 1 losses can run $5,000 to $15,000. Large-loss commercial or multifamily water events can exceed $200,000. JH Construction writes Xactimate scopes with line-item documentation, no lump sums, no guesswork. CSLB#929897.
