A flooded home is a shock. The water rises, belongings are affected, and you wonder where to start. The first thing to remember: your safety comes before everything else.
The short answer to «should you decontaminate?» is: it depends. Not for every flood, no, but certain situations require it. At Solutions Rénovation Québec (RBQ license 5811-7821-01), we handle restoration after water damage. Specialized decontamination work, however, must be entrusted to qualified professionals, and we will tell you clearly if that is the case for your home.
What to do in the first 48 hours after a flood?
The first hours count. What you do (and don't do) in the first two days directly influences the damage and costs that follow.
The goal is twofold: stay safe, and prevent moisture from settling into materials.
Secure the premises and document the damage
Do not enter a flooded area if the electricity is still on or if the structure appears weakened. Water and electricity form a dangerous mix: do not touch any electrical appliances in a wet room. Once it is safe, photograph everything, contact your insurer and follow their instructions before throwing away or moving anything. These photos are valuable for your claim.
Extract the water and start drying quickly
As soon as it is safely possible, you must remove the water and start drying. Wet materials must be assessed and dried quickly, because mold can start to develop in 24 to 48 hours under the right conditions. Warning: this timeframe is not a guarantee. Mold can appear earlier, or later, depending on the type of water and the ambient humidity.
The trap is hidden moisture. Water migrates into wall cavities, insulation and under floors. The surface may feel dry to the touch while the material remains saturated with water deep down. It is precisely this invisible moisture that causes problems weeks later if you rebuild too quickly.

Should you decontaminate? It all depends on the type of water
Not all floods are equal. A burst drinking water pipe has nothing to do with a sewer backup, even if the damage looks identical at first glance.
It is the nature of the water that dictates the course of action. That is why we always start there.
Clean water, gray water or contaminated water
In water damage restoration, water is classified into three categories. Clean water comes from a healthy source, such as a supply pipe or a drinking water tank. Gray water contains light contaminants: dishwasher, washing machine, appliance overflow. Black water, on the other hand, is potentially dangerous: sewer backup, floodwater from outside, water that has been stagnant for some time.
The more contaminated the water, the higher the precautions. A small clean water leak dried quickly does not require the same approach as a basement flooded by a sewer backup. In the latter case, we don't play the apprentice: we call in specialists, because there is a real health risk.
Which materials must be removed?
Saturated porous materials, such as drywall, insulation and carpets, may need to be removed depending on the type of water and their condition. Beware of the famous «cut at 50 cm» rule that you read everywhere: there is no universal cut height. The extent of stripping is decided based on the materials affected, the level reached by the water and the protocol applicable to the situation. A specialist evaluates each case rather than applying a one-size-fits-all measure.
When should you call in a specialized team?
Certain signals call for a professional assessment: a persistent odor, visible mold, contaminated water, a large area affected or materials that remain damp despite your efforts. In Quebec, the BNQ 3009-600 standard serves as a reference for the investigation and rehabilitation of buildings contaminated by mold. This is the kind of work that goes beyond general renovation and requires specific skills.
Before closing up the walls, have it confirmed that the affected materials are dried and that the required work is defined.
How do you dry and restore a home in Saint-Romuald?
Once the emergency has passed and the type of water established, comes the step that makes all the difference: drying, then reconstruction. And the order is not negotiable.
Rebuilding on wet materials is a guarantee of starting all over again in a few months.
Check moisture before rebuilding
The logical sequence is this: extract the water, remove unsalvageable materials, dry in a controlled manner, check residual moisture, and only then rebuild. Each step prepares the next.
Proper drying relies on industrial dehumidifiers and air circulation equipment, but above all on actual moisture measurements. You never close up a wall simply because the surface «looks dry.» You close it when readings confirm that the material is dry deep down. That is the only way to avoid mold trapped inside the assembly.
Take climate and building into account
In the Lévis region, water damage has no shortage of occasions: spring snowmelt, intense summer rains, basement infiltration and freeze-thaw cycles that crack and let water through. A home near the river, in Saint-Romuald, lives with this reality. Repairs must therefore take into account the materials in place and the age of the building, not just the visible damage.
Request a quote for the necessary renovation work once the extent of the damage has been established.
How much does decontamination cost after a flood?
This is the question that worries people, and the honest answer is that there is no fixed price. Everything depends on the affected surface area, the materials, access to the premises and the scope of the work.
As an indication only (estimates to be validated according to your actual situation), limited clean water damage can be around 2,000 $ to 5,000 $, more significant damage or grey water from 4,000 $ to 10,000 $, and major contamination 8,000 $ to 15,000 $ or more. These ranges vary greatly from one case to another, these are not quotes.
On the insurance side, everything depends on your contract, on the cause of the loss and the exclusions provided for. Carefully keep your photos, your invoices, the reports and the humidity readings: these are your supporting documents. However, nothing can be guaranteed regarding reimbursement; it is your insurer who decides according to your policy.

FAQ: flooding and decontamination in Lévis
Does a flooded house always need to be decontaminated?
No. A small flood of clean water, dried quickly, does not necessarily require decontamination. It is the type of water, the extent and the presence of mould that determine the need for specialized intervention.
Can mould be prevented if the water is removed in less than 48 hours?
Acting quickly greatly reduces the risk, since mould often develops within 24 to 48 hours. But this timeframe is not an absolute guarantee: moisture hidden in the walls can still cause problems even after a quick extraction.
Which porous materials sometimes need to be removed?
Drywall, insulation, carpets and other soaked absorbent materials may need to be removed. The decision depends on the type of water and the actual condition of the material, not on a fixed rule applied everywhere.
How can you tell if the walls are still damp?
By sight and touch, it's impossible to be sure. We use moisture measuring devices to check the inside of materials and cavities. It is this reading, and not the surface appearance, that indicates whether we can close up.
Can you clean up yourself after a sewer backup?
It is strongly discouraged. Sewage water is potentially contaminated and presents a health risk. This type of situation should be entrusted to qualified responders, with the appropriate equipment and protocols.
Does the BNQ 3009-600 standard apply to all water damage?
No. This Quebec standard governs the investigation and rehabilitation of buildings contaminated by mould. It serves as a reference when there is contamination, not for a simple clean water damage dried quickly.
Does home insurance cover decontamination work?
It depends entirely on your contract, on the cause of the loss and on the exclusions. Some damage is covered, some is not. Keep your evidence and check your coverage directly with your insurer.
Who to contact in Saint-Romuald to restore a house?
For restoration and reconstruction, a renovation contractor holding an RBQ license, such as SRQ, can assess the work. For specialized decontamination or mould analysis, a competent specialist must intervene, and we will refer you if needed.
A flood is never simple, but it can be managed. By first securing the premises, distinguishing the type of water and truly drying before rebuilding, you avoid costly unpleasant surprises.
