    When there has been damage caused by water, the usual practise is to begin using dehumidification as quickly as feasible. However, given the wide variety of forms that water damage can take, as well as its varying degrees of severity, it is essential to tailor one's response to each specific instance.

    In the event that water damage has occurred, the length of time that water has to work its way through the building's structure, furniture, and so on is a significant factor to consider. To prevent moist air from entering the space, it is vital to maintain as low an air change rate as is practically practicable. You will find some directional empirical data in the rule of thumb that is located in the appendix. In the event that there has been water damage, it is very difficult, if not impossible, to accurately calculate the amount of dehumidification that is required.

    When it comes to the process of drying out a building that has recently been erected, you should also keep air change minimal; nevertheless, the water content of the various materials employed is the most crucial criterion to take into consideration. You will frequently be required to meet a deadline, which means that you only have a finite amount of time to complete the task at hand.

    If you let water damage go unchecked for an extended period of time, it will not only be an eyesore, but it could also become a health hazard. In the event that water damage has occurred, the most prudent thing to do is to get in touch with the experts. Water damage specialists are equipped with the tools and methods standard in their business, allowing them to competently put the situation under control.

    It is essential to begin drying out your home as soon as possible following an occurrence that causes water damage; you can begin working towards this goal immediately or get professionals in as soon as they are able to. This article offers some suggestions for effectively drying out a residence that has sustained water damage. Planning to build a home? MJS Construction Group brings your building project alive!

    Remove Water To Prevent Contamination

    Eliminate any water and any standing water that may still be present in your residence. If you didn't clean up after the flood, you could end up with mould, germs, and other unpleasant growths. This is something you definitely want to avoid. Take everything out of your kitchen, bathroom, and any other rooms that the water leak may have impacted.

    Air Out Your Home

    It is in your best interest to throw open all of your home's windows so that outside air can enter. Open them up to the point where they are exposed to sunshine but not draughts or moisture from the surrounding environment. In addition to this, it will assist in the elimination of any residual moisture that may be present in your home, making it simpler for trained professionals such as ourselves to dry out the affected areas using dehumidifiers (if needed).

    Save Your Belongings

    It is important to remove any valuables and pieces of furniture that could potentially be damaged by water. This includes the mattress, box springs, pillows, couch cushions, documents, and electronic devices, among other things. In the event that certain goods are not properly cleaned following water damage, they may serve as a fertile ground for the growth of mould or germs.

    Therefore, you need to make sure that you clean them up as quickly as possible using appropriate cleaning products that are specifically intended for soaking up water.

    When storing anything that you wish to keep dry, use plastic bags or other containers that are waterproof. This will prevent any more harm from occuring.

    Clean Your Walls

    If the water damage is of the category 1 variety, you could find that a solution of bleach and water is the most effective way to clean your walls. It's possible that the cleaning solution you need to use will change based on the kind of water damage and the kind of wall you have. If you want to avoid getting any of the bleach on your walls, you should apply this solution with a sponge or rag. Then, using a fresh cloth to wipe everything down, eliminate any excess moisture that may be present in them.

    Use Fans

    Utilize fans to hasten the drying process inside your home, particularly if there is still standing water inside after you have cleaned up everything else that was affected by the flood. In the event that you do not have any fans, you should open some windows to get the air moving.

    Use Dehumidifiers

    Utilize a dehumidifier to remove any lingering moisture from the air inside your house, particularly in the areas of the basement, bathrooms, and kitchens.

    You can rent or purchase a dehumidifier online for as little as $20 a month, and either option is an affordable one. However, keep in mind that the use of dehumidifiers of this kind should be regarded as a band-aid remedy, as their effects are typically just brief.

    The severity of the damage caused by water might change from one instance to the next.

    You require the assistance of professionals who can analyse the situation, permanently address any difficulties, and employ dehumidifiers and other machines that are appropriate for the job. When we come to clean your home, we will bring along this machine with us.

    Clean Carpets

    When it comes to the carpet, you should be sure to utilise a cleaning machine that is equipped with attachments that are suitable for use in a professional setting in order to extract the water from your carpets and upholstery. After there has been water damage, it will assist in preventing the growth of mould or mildew.

    You can also set fans in the rooms that you wish to dry and switch on the power to those fans for a period of a few hours. The process of drying out your carpets will go more quickly as a result of this.

    Be Cautious With Chemical Cleaning Solutions

    When utilising any chemical cleaners in the process of flood cleanup services, you must ensure that all appropriate measures are taken. We will only recommend these cleaners in the event that your home has sustained significant damage as a result of a major flood. Utilizing chemical solutions without having the necessary knowledge or equipment can be quite risky. This is especially true in situations when you do not have adequate protection.

    Add A Fresh Coat Of Paint

    It is usually a good idea to give the interior surfaces of your home a fresh coat of paint after you have finished cleaning up and drying out your property after it has been flooded. After you have finished all of the cleaning and drying work that we conduct for you, it will prevent any mildew or mould that may still be there from growing inside the building.

    Seek Professional Assistance

    It is always a good idea to have another pair of eyes examine the outcomes of any water cleanup project that was done before you approach us for our flood cleanup services. This is because the outcomes of any water cleanup operation can vary greatly. It will ensure that all areas are clean and free from mould or germs, as well as free from excess moisture, so that following the cleansing, they will be able to dry out correctly.

    After water damage has been sustained, one of the most important steps in the restoration process is drying out the affected area.

    On the other hand, if you do not take the necessary safeguards, it may end up costing you a lot of time and money. Don't put off the process of drying things out because you lack the experience, tools, and expertise to accomplish it properly.

    You might also make an urgent phone call to a professional to have them start drying up your home. It will take less time to dry out your property and restore it to its normal functionality if you get started on the project sooner rather than later.

    Heating And Ventilation

    By utilising this strategy, you will raise the temperature of the air within the construction site, as well as implement rigors ventilation. The effectiveness is quite sensitive to the surrounding environment. In general, the approach is going to be more effective when the temperature outside is lower and the temperature within the room where the dehumidifier is located is going to be greater. Who, then, is capable of achieving the finest results throughout the winter months?

    When dehumidifying humid walls, the temperature in the room should not be higher than 35 degrees Celsius. The walls may get damaged and crack as a result of higher temperatures, which might create an excessive increase in the pressure of steam that is confined within the walls.

    This method of humid dehumidifying walls leads steam to be absorbed by drier areas of the walls and the ceiling if adequate ventilation (air exchange) is not provided. It is also important to be aware that warming the air with gas heaters has the opposite impact of what one may reasonably anticipate it to have. See our list of available builder services melbourne to help you make an informed decision for your treatment.

    The production of carbon dioxide and steam is the result of the combustion of propane and butane. That translates to the fact that a rise in air temperature also results in an increase in air humidity!

    It will set you back a lot of money to dehumidify your construction site by using heating and ventilation. It is primarily as a consequence of the low effectiveness (the length of time necessary for dehumidifying is considerable), as well as the fact that the optimal results can only be accomplished at high temperatures (this requires a lot of heating power).

    Condensation Dehumidifying

    The basic idea behind condensation dehumidification is to remove humidity from the air by cooling it below the dew point, where it will then condense. This is how the process is described. Dehumidifiers that work on the basis of condensation are called condensation air dehumidifiers.

    An extractor fan, a compressor, heat exchangers (both an evaporator and a condenser), and an expanding element are all included in their construction. The extractor fan propels the moist air through the heat exchangers in a controlled manner.

    Because the temperature of the evaporator is lower than the temperature at which dew point occurs, humidity in the air will condense as a result. The condensate is either collected in a tank that is connected to a dehumidifier or transported to either the sewage system or the outside environment via drainage.

    Following its journey through the evaporator, the air is then dried out as it travels through the condenser, which causes it to experience an increase in temperature. The level of relative humidity has continued to fall as a direct result of this. After that, the now-dry air is brought back into the space.

    The air temperature that exits the dehumidifier is anywhere from 3 to 8 degrees Celsius higher than the air temperature that goes into the device. The increase in temperature described above may induce faster evaporation of water, for example from wet walls, which enables dehumidifying rather than providing a risk of damage as is the case with the method of heating and ventilation.

    The operating parameters (temperature and humidity) as well as the characteristics of the condensation dehumidifier that is being used play a role in determining how effective the device is at removing moisture from the air. When both the temperature and the relative humidity are above a specified threshold, condensation dehumidifiers operate at their most efficient level.

    On the other hand, what this indicates is that the efficiency of this kind of machinery will improve in proportion to the decrease in the amount of water present. Condensation dehumidifiers, as a rule, are not appropriate for use at temperatures lower than 0 to 5 degrees Celsius.

    Condensation dehumidification uses far less power and completes the drying process more quickly than traditional drying methods like heating and ventilation. This is partly because condensation dehumidification does not require the room's air to be replaced. Because of this, it is the method that is recommended and considered to be the most efficient for removing excess moisture from the majority of building sites.

    Adsorption Dehumidifying

    The removal of humidity from the air is accomplished using a technique known as adsorption dehumidification. This involves the use of hygroscopic materials to absorb the moisture. Adsorption dehumidifiers typically have a rotor, a drive unit, extractor fans, an air warmer, a filter, a casing, and fittings in addition to other components.

    The rotor is generally composed of appropriately shaped aluminium sheets (producing axial capillaries) with a surface covered by a hygroscopic material.

    It contributes to an increase in the area and capability of the unit for absorbing humidity.

    Both dehumidifying and regeneration functions are built into the design of the dehumidifier.

    The movement of the humid hygroscopic material to the regeneration sector, which is where hot air passes through the rotor to remove humidity before it is released into the atmosphere, is caused by the turning of the rotor.

    In addition, the rotor has a high level of durability, can be cleaned with water, has the ability to clean itself, and may inhibit the growth of bacteria.

    The fact that this dehumidifier can remove moisture from the air without the need for cooling or temperatures below zero is a significant benefit of using it.

    This technique is more commonly utilised in industrial settings, such as pharmaceutical, food, and air conditioning (AC) systems, as opposed to building sites, due to the numerous benefits that it offers.

    Heat Vs Dehumidification: What's The Best Choice?

    When it comes to removing moisture from a building site, the tools that are utilised most frequently are heaters and dehumidifiers. When contrasted with the other approach, the use of dehumidifiers is the more successful choice.

    The temperature of a space can be raised by using heaters, which work by drawing air through a heating system.

    This does not work to remove moisture from the air because heaters do not have any kind of internal mechanism for wicking moisture. Many people are now questioning the wisdom behind the practise of using heaters to dry up construction zones in the past.

    When temperature is raised by healers, the amount of moisture present in the air reduces in proportion to the temperature. The conditions of a site are thereby improved, albeit only somewhat, as a result of this.

    When areas are dried utilising humidifiers, they go through a mechanism that directly removes moisture from the air. This helps the areas become drier. When moisture is removed from the air, vapour pressure drops because of the direct correlation that exists between moisture content and vapour pressure.

    In terms of expenses, there are further distinctions to be made between heating and dehumidifying as ways for drying out building sites:


    • Low start-up cost
    • High maintenance costs
    • Dehumidifiers:
    • High start-up costs
    • Significantly lower maintenance costs

    Materials for Construction Being Dried Even while a lot of people think that relative humidity is the most essential aspect in drying out a building material, there is actually something else that has a much bigger role. Let's say you take the temperature and the relative humidity of your building space and plot them on a psychrometric chart (Psychrometrics is defined as studying the dynamic properties of water-air mixture).

    In that instance, you will be able to calculate the humidity ratio or the actual amount of moisture that is present in the airspace that you are analysing. Using this information, you may conclude (by way of direct correlation) that the vapour pressure is the most important factor in moisture management.

    In environments where the atmosphere is not carefully managed, such as an interior construction space, the water molecules that are present in the air exert a force known as vapour pressure on the substances that they come into contact with. To varying degrees, porous materials, which make up the majority of the components found inside of a structure, are able to take in water vapour.

    Moisture will, as a matter of course, move from regions with high vapour pressure to regions with lower vapour pressure. Imagine you have the ability to lower the vapour pressure in the construction space to a point where it is lower than the vapour pressure of the building materials.

    After that, the moisture vapour will either be absorbed by these materials or released from them, and positive air movement will cause it to be expelled from the space.

    You may naturally force excess moisture content out of your construction materials under the correct climatic conditions until they have attained equilibrium moisture content. This is the point at which a material is no longer releasing or taking on ambient moisture from the air around it.

    A Comparison Of Technologies

    During the construction process, most commonly, contractors will utilise either heat or desiccant dehumidifiers to dry building materials in order to better control the amount of moisture that is present. In the meantime, there has been a lot of discussion regarding the technology that is the most efficient for drying applications in the construction industry; however, the scientific fact is indisputable. This article will help you make a decision about home building constructionHere at MJS Construction Group, we’re committed. 

    When compared to a dehumidifier in terms of their ability to pull moisture out of the air, a heater simply cannot compete with its dehumidifying counterpart. The actual moisture that is present in the air of a building will not be removed by merely bringing heat into the space.

    A system that exclusively generates heat will, by its own nature, raise the temperature of an airstream by passing that airstream more than once over some kind of heating apparatus.

    For instance, a direct-fired heater blows air directly over a flame that is fueled by propane or natural gas. On the other hand, an indirect-fired heater blows air through a heat exchanger, which prevents the supply air from coming into contact with the combustible materials that are being emitted from the fuel source. Direct-fired heaters are more common.

    In either scenario, there is one element that remains the same: an internal component that removes moisture and, as a result, does anything to address vapour pressure is not present in a system that merely provides heat.

    The next question that naturally arises is why, in previous years, we used heaters to assist in drying out construction sites. The response, despite being straightforward, frequently leads to misunderstandings. When the temperature in a building space is raised with a heater, the amount of water vapour in the air decreases in proportion to the rise in air temperature. There is no reduction in the amount of moisture in the air as a result of the temperature being raised; however, the humidity is lower than the temperature being raised. As a direct consequence of this, the environmental conditions in the construction space are going to be (relatively) improved.

    A direct analogy can be drawn between the operation of a dehumidifier and that of a heating system in that as air moves through the desiccant material contained within a dehumidifier, the moisture is absorbed by the desiccant material and, as a result, removed from the airstream. Because there is a direct correlation between the amount of moisture present and the vapour pressure, reducing the amount of moisture in an airstream will also result in a reduction in the amount of vapour pressure that is present in that airstream.

    Last but not least, when contrasting heat and dehumidification, it is essential to investigate the costs of operation that are connected to each of these technologies. In order to generate heat, a heating system must have a fuel source that is either directly or indirectly passed over a flame. In order to achieve high temperatures, these systems require the utilisation of boilers or heat exchangers that run on significant amounts of diesel, propane, or natural gas.

    The initial investment for heat-only systems is usually not very high; nevertheless, the ongoing expenses are typically quite high due to the high amount of fuel that is required to run the system. This contributes to the overall high cost of employing this technology. In addition, the upfront expenses connected with desiccant dehumidification are legitimately greater due to the significantly increased complexity of the technique.

    In spite of the fact that they are more expensive to purchase initially, dehumidifiers have substantially lower operating expenses than systems that merely provide heat since they require a lot less fuel to fulfil their purpose. In addition, recent advancements in technology, such as remote monitoring and control of equipment as well as energy-efficient dehumidification devices, have contributed to the creation of further cost reductions regarding operational expenses.

    Frequently Asked Questions About Home Building

    Rock Salt. Rock salt is a natural hygroscopic material that absorbs moisture and stores it — similarly to dehumidifiers. However, rock salt is completely natural, non-toxic and requires no electricity. Rock salt is a crystal mined from underground and taken to a special facility.

    If left untreated, dampness can pose several risks, including structural timber decay, damage to plaster, corrosion, health issues for those with asthma and respiratory problems, unsightly staining and mould growth.


    Indeed, the damp-proofing industry's Code of Practice states that "walls will take at least 6 to 12 months to dry out. The presence of paints or renders will substantially extend the drying period".

    Ideally buildings should be dried out by the central heating system where possible, with the thermostat at 22°C or above. If possible use heaters, fans and dehumidifiers to aid the process. Good ventilation of the building will aid the drying out process, open as many doors and windows as possible.

    Over time this moisture will gradually disappear and, as shown in the diagram below, you should expect your new home to reach a moisture- balanced state within 18 months to 2 years.
