TL;DR: The first hour after water damage decides how much you lose. Shut off the water source and cut power to any affected area, then photograph everything before you start cleaning up. Denver’s dry air can make a wet carpet look fine within hours while the padding and drywall underneath stay soaked, so dry on top does not mean dry underneath. Mold can start within 24 to 48 hours. Call 303-322-5131 for 24/7 emergency water damage restoration.
What to do after water damage starts the moment you find it, not after you have called anyone. A burst pipe, an overflowing water heater, or a leaking roof during a spring storm all follow the same clock, and that clock is already running.
Denver adds its own twist. Our dry climate and altitude mean a soaked carpet can feel dry to the touch within a few hours, which tricks a lot of homeowners into thinking the problem solved itself. It did not. The padding underneath and the drywall behind the baseboard hold onto moisture far longer than the surface does, and once the furnace kicks on for the season, that trapped humidity gets pulled through the ductwork and spread to rooms that were never actually wet.
Here is what actually matters in the first hour, in the order it matters.
What Should You Do in the First Hour After Water Damage?
Stop the water at its source, cut power to any outlet or fixture in the affected area, and photograph the damage before you move or clean anything. Do this before you call your insurance company and before you call a restoration company. Once the immediate hazards are handled, remove valuables you can safely reach and start the drying process, either your own fans and a dehumidifier or a professional crew, since standing water and trapped moisture both get worse by the hour, not the day.
Shut Off the Water and the Power First
If you can identify the source, a supply line, a water heater, a washing machine hose, shut off the valve feeding it. If you cannot find the source or the water is rising, shut off the main water valve for the house.
Power is the more dangerous problem. Water and electricity in the same room is a real hazard, and the American Red Cross advises against entering a flooded area at all if there is any chance electrical outlets, cords, or equipment are submerged or wet. If the breaker panel itself is dry and reachable, shut off power to the affected circuits or the whole house before you do anything else. If it is not safely reachable, wait for your utility company or a professional instead of guessing.
Document Everything Before You Touch Anything
Take photos and a short video of the damage before you remove a single wet item. Get wide shots of the room, close ups of the source, and anything visibly ruined, furniture, electronics, flooring. This is the single most common thing homeowners skip, and it is the one step that most affects how smoothly an insurance claim goes later.
Keep a simple list as you go: what got wet, roughly how old it was, and what you paid for it if you remember. The Insurance Information Institute notes that sudden, accidental water damage, like a burst pipe or an appliance failure, is typically covered under a standard homeowners policy, while damage from a leak you knew about and ignored usually is not. That distinction is exactly why the photos matter: they show what happened and when, before anyone starts drying it out or throwing it away.
How Fast Does Mold Actually Start Growing?
Faster than most people expect. The EPA states that mold can begin growing within 24 to 48 hours on a wet surface, and once it starts, it does not reverse itself with time or fresh air alone.
In Denver, that clock is easy to misjudge. Low humidity dries the visible surface fast, so a carpet or a section of drywall can look and feel fine well within that 24 to 48 hour window. But mold does not care what the surface looks like, it cares what is happening inside the material, in the padding, in the wall cavity, behind the baseboard. Those spots stay wet long after the top layer feels dry, and that is exactly where mold gets its foothold. If you are not actively drying the affected area with fans and a dehumidifier, or having it done professionally, assume the clock is still running even if everything looks okay on the surface.
What to Save, What to Toss, and What to Leave for Professionals
Move anything you can safely lift off the wet floor: furniture legs, boxes, electronics, rugs. Photos, documents, and books can usually be saved if you get to them within the first few hours, laid flat and air dried or gently fanned.
Porous materials that have been sitting in contaminated water, carpet padding, drywall, insulation, upholstery soaked for more than about 24 to 48 hours, are a different story. These materials hold onto moisture and, if the water came from anywhere other than a clean supply line, hold onto contamination too. In most cases they need to be professionally dried, treated, or removed rather than saved, since drying them out on your own rarely reaches the parts that actually stay wet.
If the water damage reached your carpet, our carpet cleaning team can assess whether it is salvageable once the structural drying is done. If it reached your ductwork, trapped moisture in the system is worth having checked with air duct cleaning once things have dried out, since damp ducts are a common place for mold to take hold quietly.
Does Homeowners Insurance Cover Water Damage?
Usually, yes, if the damage was sudden and accidental. A burst pipe, a failed water heater, or an overflowing appliance are the kinds of events a standard homeowners policy is built to cover. Gradual damage from a leak you already knew about, or damage you let sit unaddressed, is the kind insurers commonly deny, according to the Insurance Information Institute.
This is exactly why the first hour matters twice: once for the damage itself, and once for the claim. Acting fast and documenting everything is what turns “we had a pipe burst” into a claim that actually gets paid. A1 Red Carpet works with insurance claims regularly and can provide documentation of the drying and restoration process for your adjuster.
When to Call a Water Damage Restoration Company
Call a professional if more than one room is affected, if water reached the padding, drywall, or insulation rather than just the surface, if the water came from anything other than a clean supply line, or if it has already been more than a few hours since the damage happened. Any one of those on its own is a reasonable reason to stop treating it as a DIY job.

The first hour after water damage is the one that decides whether this becomes a quick fix or a much bigger, more expensive problem. Shut off the water and the power, document everything before you clean up, and get real drying started fast, whether that is your own fans or a professional crew.

Frequently Asked Questions
How long can water damage sit before it becomes a bigger problem?
Treat 24 to 48 hours as the real deadline. That is the window the EPA cites for mold to start growing on a wet surface, and it is also roughly when porous materials like carpet padding and drywall stop being easily salvageable. In Denver’s dry climate, the surface can look fine well before that window closes, which is what makes this timeline easy to underestimate.
Will my homeowners insurance cover a burst pipe?
Usually, yes. A burst pipe is a sudden, accidental event, which is the category most standard homeowners policies are built to cover. Coverage gets denied more often when the damage came from a leak the homeowner already knew about and did not fix, so document the damage immediately and call your insurer the same day.
Can I dry out water damage myself without professional equipment?
For a small, clean water spill caught within the first hour, household fans and a dehumidifier can work. Once water has reached carpet padding, drywall, or insulation, household equipment rarely dries those materials all the way through, which is exactly the gap that leads to hidden mold weeks later.
What is the difference between clean water and contaminated water damage?
Clean water comes from a supply line or an appliance and carries no contamination on its own. Contaminated water, from a sewer backup, groundwater flooding, or water that has been sitting for more than a day or two, carries bacteria and other hazards, and materials it touches usually need to be professionally treated or removed rather than dried and reused.
How much does emergency water damage restoration cost in Denver?
It depends on how much water intruded, what materials were affected, and how long it sat before drying started, which is exactly why acting in the first hour matters for cost, not just for the damage itself. A1 Red Carpet provides free, no obligation estimates and can walk you through likely costs during that first visit. Call 303-322-5131 any time.
