If this is happening right now. Electricity first: if water is anywhere near outlets, a panel or submerged appliances, kill the power at the breaker — and if you would have to stand in water to reach the panel, do not, call the utility. Then stop the source at the main shut-off. Then photograph and video every room before anything is moved. Those three things, in that order, before you call anyone. Once the property is safe and the source is stopped, you can reach HyreRestore on (866) 582-8523 — but we are a research desk, not an emergency line, and a local company will always be faster.
The short version
- Two classifications drive everything: the category of the water (how contaminated) and the class of the intrusion (how much material absorbed it).
- Clean water can stop being clean. The industry standard treats category as something that degrades with time and contact, which is why a Sunday leak found on Wednesday is a different job.
- Drying is finished when readings hit a goal set from undamaged material in the same building — not when the equipment has been there a week.
- You should be given the moisture log, not told about it. Daily readings per location are the single clearest sign of a professional operation.
- Mitigation and reconstruction are two separate jobs, usually two invoices, and frequently two companies. You are generally not required to use the drying company for the rebuild.
- Standard policies commonly cover sudden and accidental discharge and exclude flood and long-term seepage — which is why what caused it matters as much as what it did.
Signs you are past the point of a mop and a fan
Surface water is the visible part of the problem and rarely the expensive part. These are the conditions where household drying will not finish the job.
- The water reached drywall, insulation, subfloor or cabinetry — porous assemblies hold water long after the surface reads dry.
- It has been more than a day or two. The EPA’s guidance is that mould can begin growing on damp materials within 24 to 48 hours.
- The source was a sewer line, a toilet beyond the trap, or water that came in from outside. That is a contamination problem before it is a drying problem.
- You can smell it. A musty smell in a room that looks dry means something behind a surface is not.
- Flooring has cupped, buckled or lifted, or you can feel give underfoot.
- Ceilings are stained, sagging or dripping — the water is travelling through a cavity you cannot see into.
- It is a finished basement, where the wall assembly, the slab and whatever is stored against them all hold water differently.
What a restoration technician should assess before quoting
The inspection is the part that decides everything downstream. A company that walks in, places equipment and works out the scope later has inverted the job.
- The source, and whether it is actually stopped. Drying a building that is still getting wet is billing, not restoration.
- The category of the water, and how long it has been in contact with materials.
- The affected area, mapped — with a moisture meter and usually a thermal camera, not by eye. Water wicks up walls and travels under flooring well past the visible edge.
- What the assemblies are made of: plaster or drywall, hardwood or engineered floor, what insulation is in the cavity, whether the subfloor is plywood or OSB.
- A dry standard — readings from the same materials in an unaffected part of the building, which become the target.
- Temperature and relative humidity inside and out, which decide what dehumidification will physically achieve.
- Safety: electrical hazards, structural concerns, asbestos or lead in an older building before anything is cut.
- Contents — what needs moving, cleaning, packing out or writing off, which is a separate scope from the structure.
What the work involves, in order
- 01
Make safe and stop the source
Power isolated where water is near electrics, the supply shut off, any opening in the envelope covered. Nothing else starts until this is true.
- 02
Document the pre-existing condition
Photographs, video and written notes of every affected area before anything moves. Do this yourself as well — it is your claim, and it is free.
- 03
Extract standing water
Removing bulk water is enormously faster than evaporating it. Extraction from carpet and pad, and from hard floors, happens before equipment is placed.
- 04
Inspect and map moisture
Meter readings across affected and unaffected materials, marked up on a sketch, establishing the drying goal and the true boundary of the loss.
- 05
Remove what cannot be dried
Wet insulation, saturated carpet pad, and drywall cut back to a line above the wicking. On a category 3 loss this is most porous material the water touched.
- 06
Contain where contamination is involved
Barriers, negative air pressure and HEPA filtration so that demolition does not move the problem into clean rooms.
- 07
Set the drying system
Air movers and dehumidifiers sized to the volume and the class of the loss, positioned to move air across wet surfaces rather than around a room.
- 08
Monitor daily
Readings of material moisture content per location per day, plus temperature and humidity, recorded against the goal. Equipment is added, moved or removed based on what the numbers do.
- 09
Confirm dry and demobilise
Readings meet the goal, a final set is recorded, equipment comes out. The log — not the calendar, and not the technician’s opinion — is what ends this phase.
- 10
Hand over to reconstruction
Rebuilding starts from a dry structure. This is a separate scope, separately priced, and the phase where you have time to compare bids.
The two classifications a scope is written against
The category of the water and the class of the intrusion both come from the ANSI-approved IICRC S500 standard, which is the consensus reference for this trade in the United States. You do not need to know the numbers to hire well, but knowing that they exist changes the conversation — and a company that cannot tell you which category and class it is working to is guessing.
| Category 1 — clean | Water from a sanitary source: a supply line, a tap left running, a water heater. It is the best case, and it does not stay this way indefinitely. |
|---|
| Category 2 — significantly contaminated | Water carrying enough contamination to cause discomfort or illness: a dishwasher or washing machine discharge, an overflow from a toilet bowl with urine but no faeces. More material is removed rather than dried. |
|---|
| Category 3 — grossly contaminated | Sewage, water beyond the toilet trap, rising water from rivers or streams. Porous materials it has touched generally come out, protective equipment and containment are not optional, and this is not a do-it-yourself situation at any scale. |
|---|
| Class of intrusion (1 to 4) | How much material absorbed the water and how readily it will give it back. A small spill on tile and a soaked plaster-and-hardwood assembly can involve the same volume of water and completely different drying effort. Class 4 describes deeply held water in low-evaporation materials, which needs specialist methods and time. |
|---|
| Why category can change | The standard treats category as a condition at a point in time, not a permanent label. Clean water sitting in contact with building materials, soil or contents deteriorates. Time is the variable you control. |
What moves the price
A water loss is normally two invoices with different logic behind them. Mitigation is equipment, labour and days. Reconstruction is a building job priced like any other building job.
| Factor | Why it changes the number |
| Category of the water | The largest single lever. Category 1 dries much of what it touched; category 3 removes it, disposes of it under different rules, and adds containment and protective equipment. |
|---|
| Class of intrusion | How much material absorbed water, and how reluctantly it gives it back. Deeply held water in hardwood, plaster or a cavity takes more equipment for longer. |
|---|
| Affected area | Rooms, and whether water reached more than one floor. Ceilings below a loss are frequently the larger part of the scope. |
|---|
| Equipment count × days | The core of the mitigation invoice. This is exactly why daily readings matter to you financially: the log is what closes the line. |
|---|
| Demolition and disposal | What has to come out and where it legally goes. Contaminated material carries different disposal requirements from clean construction debris. |
|---|
| Containment and protective equipment | Barriers, negative air machines, HEPA filtration and PPE where the category requires them. |
|---|
| Contents | Moving, cleaning, packing out and storing belongings. Easy to overlook until the invoice, and a legitimate separate scope. |
|---|
| Reconstruction scope and finishes | Drywall and paint is one number; cabinetry, stone and matching a discontinued floor is another. Whether existing materials can be matched at all is a real cost driver. |
|---|
| Access and response time | Out-of-hours emergency response, and how easily equipment and crews can reach the affected area. |
|---|
| Local conditions | Ambient humidity changes how hard drying is, and regional labour and material costs change the rebuild. |
HyreRestore publishes no average price for this work. Category of loss, affected area, how long equipment runs and local rebuild costs move the number far enough that a single figure would mislead more than it helped.
How a water claim usually treats this
What follows is how standard homeowners policies commonly work, not what your policy says. Your declarations page and your state decide the actual answer.
| Sudden and accidental discharge | A burst supply line or a failed appliance hose is the classic covered water loss. The damage is usually covered; the failed part itself often is not. |
|---|
| Gradual seepage | A slow leak that went on for weeks or months is commonly excluded as maintenance rather than an accident. This is where most water claim disputes actually live. |
|---|
| Flood | Water that rises from outside is generally excluded from standard homeowners policies and covered separately, commonly through the National Flood Insurance Program. Water from above and water from outside are different perils with different paperwork. |
|---|
| Your duty to mitigate | Policies generally require you to take reasonable steps to prevent further damage once you know about it. Emergency extraction and drying are normally expected and normally covered. |
|---|
| Mitigation versus reconstruction | Frequently handled as two parts of the claim, sometimes with the mitigation invoice paid before the rebuild scope is even agreed. |
|---|
| ACV or replacement cost | Whether you hold actual cash value or replacement cost decides whether depreciation comes back to you after the work is done. Check which one you have before you need to know. |
|---|
| Additional living expenses | If the property is uninhabitable, many policies cover the extra cost of living elsewhere. Keep every receipt from day one. |
|---|
| Supplements | Damage found after demolition is submitted as an addition to the claim with documentation. Routine, and not a sign that something has gone wrong. |
Coverage is decided by your own policy and the peril, not by what is typical. Read the declarations page, and where the answer matters, put the question to your insurer in writing.
The one thing to ask on day one. “What is the drying goal, and will I get the daily readings?” It takes five seconds, it cannot be answered with marketing, and it changes how the job is run from that point on. A company that sets a goal and logs against it is running a measured process. One that cannot answer is running a rental business.
Estimate a drying window from the class of loss
What to ask before you sign
- Which category and class are you scoping this as, and what did you measure to decide?
- What is the drying goal, where did the dry standard come from, and will I receive the daily log?
- What exactly are you removing, and what are you drying in place?
- Is this quoted as mitigation only, or does it include reconstruction? Can I see them as two documents?
- Am I required to use you for the rebuild if you dry it?
- Which IICRC certifications do the technicians on this job hold — not the company, the people attending?
- What am I being asked to sign: a work authorisation, or an assignment of benefits?
- How do you handle contents — cleaned on site, packed out, or my responsibility?
- Who is my named point of contact, and how do I reach them outside business hours?
- What happens if the adjuster’s scope and yours disagree?
The full ten-point checklist is on choosing a restoration company.
What to have ready
- Photographs and video of every affected room, taken before anything moved.
- Your policy number, the claim number once you have it, and the adjuster’s name.
- What you know about the source, and roughly when it started.
- The age of the building and, if you know it, what the floors and walls are made of.
- Any receipts already accumulating — emergency plumber, hotel, replacement essentials.
- A list of what was in the affected rooms, with photographs, before anything is discarded.
Where this goes wrong
Throwing things out before the adjuster has seen them
Damaged contents are the evidence for that part of the claim. Photograph, inventory, and hold until the adjuster has seen them or released you in writing. Early disposal is one of the most common causes of a reduced settlement.
Accepting "it will be dry in three days"
Duration is an output of measurement, not an input. A confident number given before anyone has taken a reading is a sales figure. So is equipment still running after the readings hit the goal.
Signing an assignment of benefits on the doorstep
It transfers your right to the insurance payout to the contractor. Legal in most places, sometimes genuinely convenient, and abused often enough that several states have legislated to restrict it. A reputable company will wait while you read it — that willingness is the test.
Letting the rebuild start on a wet structure
Closing a wall over material that has not reached the goal is how a water loss becomes a mould claim six months later. Ask for the final readings before anything is boarded back up.
Assuming you must use the insurer’s preferred vendor
Preferred vendor programmes exist and those companies are often perfectly good, but in most cases you choose who works on your property. Your insurer decides what it will pay, not who holds the meter.
Treating surface dryness as finished
Wall cavities, subfloors and the space under cabinetry stay wet long after the surface reads dry. If nobody has measured inside the assembly, nobody has measured the part that matters.
Common questions
How long does water damage restoration take?
The drying phase is measured rather than scheduled. Equipment runs until moisture readings in the affected materials reach a goal set from undamaged materials in the same building. Several days is common for a contained category 1 loss; assemblies that trapped water, and category 3 losses with substantial removal, take longer. Reconstruction afterwards is a separate timeline driven by scope, materials and the claim. If nobody can show you a reading, nobody can honestly tell you how long it will take.
Can I dry it out myself with fans?
Sometimes, for a small clean-water spill on hard surfaces caught immediately and confined to the surface. The problem is that household fans move air without removing moisture from it, so in a closed room they can simply relocate water into other materials. Anything that reached drywall, insulation, subfloor or cabinetry, anything that has sat for more than a day, and anything contaminated is past that point.
Will my homeowners insurance cover water damage?
It depends on the peril and your policy. A sudden accidental discharge — a burst supply line, a failed appliance hose — is commonly covered. A slow leak that went on for months is commonly excluded as a maintenance issue, and flood is generally excluded from standard homeowners policies and written separately. Your deductible and whether you hold actual cash value or replacement cost decide what actually reaches you. Ask your insurer about your specific policy rather than relying on what is typical.
What is the difference between mitigation and restoration?
Mitigation is the emergency phase: stopping the source, extracting water, removing unsalvageable material and drying the structure to a measured goal. Restoration or reconstruction is putting the building back — drywall, flooring, paint, cabinetry. They are separate scopes with separate pricing logic and frequently separate companies. The rebuild is the phase where you have the most time to compare bids, so it is worth using it.
Do I have to use the restoration company my insurer recommends?
Generally no. Insurers maintain preferred vendor programmes and those companies are often good, but in most cases you choose who works on your property. What your insurer controls is what it will pay for. If you go outside the programme, the scope still has to be agreed with the adjuster in the same way.
How fast does mould start after water damage?
The EPA’s guidance is that mould can begin growing on damp materials within 24 to 48 hours. That window is why response speed matters far more than choosing quickly — you can have extraction and drying running today under a limited emergency authorisation and still take days to decide who does the rebuild.
What should a moisture log actually contain?
Dated readings of moisture content in specific, named materials at specific locations, taken daily, alongside temperature and relative humidity, with the drying goal stated and the dry standard it came from. It should also record which equipment was placed where and when it was moved. And it should be given to you, not merely held on file.
Is a water heater or washing machine failure covered?
The resulting water damage is commonly covered as a sudden accidental discharge. The appliance itself usually is not — policies cover the damage a failure causes rather than replacing the thing that failed. If the failure was gradual and visible for a long time, the insurer may treat it as maintenance instead.
Does category 1 clean water still need professional drying?
Often yes, because the issue is not the cleanliness of the water but where it went. Clean water that soaked into a wall cavity, under a floating floor or beneath cabinetry behaves the same as any other water once it is in there. It is also why time matters: the standard treats category as something that degrades with contact and time rather than a permanent label.
Who pays the restoration company — me or my insurer?
That depends on the arrangement you agree. Many restoration companies bill the insurer directly, which is legitimate and convenient. The document that permits it matters: a work authorisation lets them do the work and bill, while an assignment of benefits transfers your rights under the claim to them. They are not the same thing and are sometimes presented as though they are.
