Water damage remediation – McGill

Property owners in McGill experience burst pipe damage regularly. Whether you’ve suffered from a natural disaster or a localized catastrophe such as a building flood, Critical Control is standing by to respond 24/7.

If a storm, flood or burst pipes cause water to get into a home or structure water damage can occur most of the time. Sometimes the damage is visible and obvious, sometimes it is minor or hidden.

It’s more complex than simply drying the interior of the building to repair water damage. Modern professional water damage remediation techniques like Critical Control, can often mitigate damage that would otherwise need a total structural replacement.

Water Damage Restoration Guidelines are readily available – Call a Professional

A lot of times, homeowners or builders attempt to repair water damage with DIY methods that can be located online. This is not a good idea. Water damage can be controlled according to the established guidelines. These guidelines call for the knowledge and skills of professionals. These guidelines are detailed in the IICRC Standard Reference Guide or Professional Water Damage Restoration publication. This guide exists because of the necessity for professional standardisation in situations involving water destruction to buildings and homes as well as the risk they pose.

The IICRC guidelines assist restoration experts such as Critical Control to evaluate the severity and type of damages on every project.

These guidelines are essential for water damage professionals. There are situations that warrant our bringing in an Indoor Environmental Professional (IEP). An IEP is an individual with the knowledge and knowledge to assess an area for contamination, take samples, run lab tests and offer us suggestions on the type of water damage.

This is crucial in situations where the building’s inhabitants are at risk or are concerned about contamination.

Water damages caused by categories and classes


Projects for water damage restoration are classified into two categories according to the extent of the water infiltration is.

The water that enters the building was classified based on its contamination. Category 1 is water that comes from a clean source like a tub or sink or a water source that bursts.

Category 2 is water that contains significant amounts of contaminants and has the potential to cause discomfort of illness should it be consumed or ingested. These sources can be water that isn’t obvious as a danger such as the effluent from washing machines, or the overflows from toilets.

Category 3 water is grossly contaminated meaning that it can contain pathogenic, toxic or other harmful substances within it. It can be caused by leaks from toilet traps, as well as the flooding of streams and rivers. This water may contain pesticides, heavy metallics or other toxic substances.


We can also use the IICRC’s classes to determine how much water has entered your property. This is basically an indication of the amount of water a building or house should be.

Class 1 is the smallest amount of absorption and water. This is when the water comes in contact with about 5percent or less of construction materials that absorb water. This is usually the case in which the majority of items affected by water are low in evaporation, which means that they don’t soak up and retain water. Concrete and masonry, as well as plaster and finished/coated wood are just some of the examples.

Class 2 refers to absorption of water and intrusion. It is approximately 5% to 40% of the total floor, wall and ceiling comprised of low-evaporation materials like plaster, wood, concrete, or the masonry.

Class 3 means that about 40 percent or more of wall, floor and ceiling surfaces are porous materials like fiberboard, insulation, carpet etc. and where other materials that don’t absorb much water such as concrete or cement have not been negatively affected.

Class 4 indicates that water is trapped in the materials that can not easily absorb water like wood, plaster, concrete and masonry. This is why special drying methods are required and longer drying times.

How to dry a water damaged building or house


Three ways to remove water from buildings are physical extraction, dehumidification and evaporation. The removal of liquid water is at about 500 times more efficient than simply having to put up with dehumidifiers or air movers. The quicker the structure dries the more efficient. Both methods of extraction and dehumidification will be affected by how much of the material is extracted.

Water damage experts employ different extraction techniques. We employ a range of equipment, such as subsurface extraction tools and self-propelled tools.

Forcible Evaporation

The remainder of the moisture gets then dried using high-speed air movers once as much water as possible has been removed.

When an object is moistened or submerged in water it absorbs some of the moisture or water. As a result, the material becomes dampened or wet.

The degree of saturation is known as the point where it becomes impossible to contain any more moisture. More humid means that the air is getting closer to saturation.

In the evaporation process the water molecules leap from a liquid to a gaseous state. This is called evaporation.

This signifies that the object has stopped absorbing moisture from the atmosphere. The saturation point is the point at which evaporation begins. Once the saturation point is reached drying will begin.

In the evaporation stage, highly-efficient air mover dry the object from two sides. They produce a powerful airflow across the surface of the object which is directed by a filter that covers the entire surface of the object.

Air mover can move 10-20 times more air than a fan , or an ordinary household fan.

Airmovers dry the object around 10 times more quickly than normal conditions, when no air mover is used.

The high-speed airflow dry the surface and sucks up the moisture pulled away by the air movers.

Make use of heat to help in the drying process.

A key component of any restoration work is the use of heat. In order to dry out any materials damaged by water, we employ a number of different types of heaters.

Electric Heaters: Electric heaters are great for drying jobs which require the use of various heat sources. This is because they can be found in various energies, which lets you operate multiple heaters at once.

You can also reduce or off electric heat while the job is being done, without affecting other heaters. To maximize efficiency and lower your energy bills you can alter the wattage of one heater, while also increasing its wattage.

Electric heaters are a common feature in restoration projects since they generate virtually no emissions and require very little water. They are more difficult to heat up and require more time to dry.

Hydronic Bioler (TES) Hydronic Bioler (TES), The boilers quickly heat up and emit very little emissions. They typically operate on natural gas or propane.

Hydronic boilers differ from electric heat in that they do not use forced-air to distribute heat. Therefore, it may be difficult to evenly heat a large area with these types of heaters. They can also be used for dry work that does not require walls or ceilings to be able to stand in place.

When electric heaters cannot be utilized, hydronic boilers can often be used. They are capable of producing radiant heat and can keep your drying area warm without the requirement of an electrical source.


We employ Low Grain Refrigerant Dehumidifiers (LGR) to keep buildings dry and homes that have experienced water damage.

The LGR Home Dehumidifier can remove 170 pints of water in a damp building which has been badly damaged by water damage each all day, every hour of the day.

The home dehumidifier can extract water from the air in the same way as an LGR Refrigerant Dehumidifier. It will also remove the 99 percent or more of the airborne mold spores by removing condensation.

Fixing Hardwood Floor Water Damage

It is essential to take away water damaged hardwood floors to ensure that repairs can be made by removing the subflooring.

First, damaged subflooring needs to be taken off and fixed. The damaged hardwood boards require sanding down or replaced. In order to ensure a uniform appearance flooring, all floors should be sanded, then restored after the repairs have been completed.

Carpets are prone to water damage

If you have been unfortunate enough to have a flood in your home it could be a stressful and expensive experience. Even if water is removed from the affected region immediately, there’s an opportunity that you’ll need to replace the flooring in the future.

After spending time and money restoring your home to its original state, it could be depressing to discover that the finished results leave something to be desired.

It is crucial to determine the severity of the damage as quickly as possible. One of the first things to address is whether the damaged area needs to be replaced. It is possible to clean the carpet and use it again after drying. This will eliminate any worries about the growth of mildew or lingering odors.

Salvaging Carpet After a Water Damage Event

There could be staining on your carpeting , especially if the water damage was very serious. Sometimes, you will have to replace your flooring in order to eliminate these stains. Another reason that might prompt you to consider replacing your carpeting is the persistent and strong smell. If you find this to be the case it is likely that you’ll have to replace the padding and carpet.

Then, consider if your floor can be dried professionally before deciding whether you want to repair it or replace it. If you’ve got a reputable company perform the cleaning, you’ll have a better idea of just how bad the water damage was. We will be able to evaluate whether or not your carpet needs to be replaced or can be salvaged. If the carpet you have is already in poor shape, some drying methods can cause further damage to it.

The main factors which will decide whether or not the carpet and padding need to be replaced are:

  • What proportion of water did you see on your carpet?
  • How long did the water stay on the carpet?
  • Quelle was the source water?

Do your carpets need to be dried, cleaned and disinfected professionally?

The carpet’s ability to stay clean is affected when the padding underneath it is damaged. Although your carpet may have dried quickly, mildew growth can still occur in the padding beneath if it isn’t dried.

The best way to be sure that your carpet is restored and disinfected after flooding is to employ a professional carpet cleaning company. When the firm has finished their task, you’ll be in a position to make an informed decision about the condition of your carpeting and decide whether or not to replace it.

Drywall that has been damaged by water

The extent of damage determines the nature and technique of repair. Water damage repair can be as simple as removing a section of drywall then cleaning it and after that, replacing it.

The flip side of the coin is that serious damage could require a complete replacement of the wall, which includes fiberglass insulation and wall studs.

The drywall that is damaged by water usually harbors mold spores that cannot be removed easily. In most instances drywalls will have to be replaced. We employ moisture testing tools that help us determine where and how extensive the moisture has become. This allows us to isolate areas of damage and keep costs restricted to only necessary damaged areas.

It also causes structural damage because it causes the wood material to expand and expand and contract. It is much more difficult to break wood if it is moistened by water. If the water is left to sit for a prolonged time, it could cause a significant amount of rot within the wood that can cause it to crack easily.


To prevent this issue, it’s important for homeowners and building owners to take care of structural damage caused by water-related issues with their property immediately after an event like a flood or water damage occasion.

Water Damage in the Foundation

Water damage to a house’s foundation can be caused by many reasons. Although not all water problems could cause structural damage, it is important to fix foundational issues as soon as possible to prevent future structural damage.

The water damage from foundations can cause a variety of issues based on the way it is dealt with. It could cause serious structural damage if it isn’t addressed promptly.


Roof Water Damage

Damage to the roof can be caused by natural catastrophes, just like foundation water damage. Roof damage can cause roof leaks and also damage the foundation of a structure or the foundation of a home.

Roof leaks can be very expensive and could have major negatives. Roof leaks can cause mold to grow, which can prove fatal. Leakage in the roof can also result in damages to the roof truss.

Leaks from the ceiling could cause your rafters to deteriorate and soften if you don’t deal with them right away. Damage to your roof can result from electrical faults, which can lead to an electric fire. There are many reasons to have roof water damage dealt with immediately following a flood, or other type of unexpected damage.

HVAC Water Damage

If your HVAC system starts to fail or brand-new equipment is found to be inoperable, it can result in structural damage to your home. Your home and business at risk because you do not have HVAC. Mold growth can lead to serious health issues.

Damage to the Pipe Water

If you’re suffering from pipe water damage, it will likely be coming from a pipe that has burst in your home. When you’ve identified leak, it’s crucial to get an expert to prevent the water from creating structural damage.

A ruptured pipe can result in serious damage. When your pipes break and water enters your home, causing severe damage and requiring repair of water damage. This is a process that can result in structural damage.

Shut off the water supply and call an experienced IICRC-certified professional at a water restoration firm such as Critical Control as soon as you notice damaged water pipes.

What is the cost of restoring water damage?

Water damage restoration cost per square foot

Based on the square feet the water damage repair and cleanup costs can vary. The following pricing breakdown can be obtained at National Flood Services for each square foot

  • Category 1 clean water: $3.75/sq. ft.
  • Category 2 gray water: $4.50/sq. feet.
  • Category 3 blackwater price: $7/square. Ft.

Is water damage covered by homeowner’s insurance?

If the cause of the damage was unintentional and sudden the homeowners insurance policy typically cover the damage. The Insurance Information Institute states that homeowners insurance can cover the repair or replacement of broken windows however, it does not cover damage due to negligence.

Neglect is defined as damage to a surface or an object that is the result of exposure, poor maintenance or general wear and tear. According to the US-based Insurance Information Institute, homeowners insurance will not cover damages from neglect.

A homeowner’s policy does not cover water damage caused by flooding. A flood policy is required. Mortgage lenders may require flood insurance in specific regions. Flooding can occur as a result of storms, ground that is saturated to the point of overflowing or surging bodies of water like rivers, ponds, lakes rivers, oceans, and streams in combination with high winds.
