    The thought of water damage occuring inside the home is the one thing that homeowners fear the most. The most challenging component of dealing with water damage is that sometimes the damage occurs without your knowledge. This is the most difficult aspect. When you figure out what's going on, you'll have to spend several thousand dollars restoring anything before you can move on. Roof Repair & Restoration Systems is the dependable firm on which you should rely if you want the best roof restoration in Melbourne. There is no need to look any further.

    One of the most common sources of water damage in the home is a faulty plumbing system. The vast majority of people believe that this refers to a dripping faucet or some clearly visible structure. On the other hand, there are times when the plumbing behind the walls becomes broken, and it is difficult to recognise the problem until it is much too late to remedy it.

    One of the most obvious signs that you may be in for a plumbing crisis in the near future is a wet or black patch on your walls, floor, or even your roof. This indicates that you have a plumbing problem in your home. Although there are a few potential explanations, such as a broken roof or a high level of humidity during the warmer months, one of the most common causes of wet places is a water leak in your pipes. A broken roof and a high degree of humidity are two more possible explanations.

    Some leaks occur in easily accessible areas, such as behind the sink in your bathroom or kitchen. Other leaks, on the other hand, may begin in pipes placed inside your home's walls. These issues frequently go unreported for long periods of time because they are hidden far behind the walls or high in the ceiling. You may detect water leaking from your roof or coming from your wall, but pinpointing the site of the leak without opening up the wall or knowing exactly where the pipes are located within your walls might be tricky. This can make determining whether the leak is originating from the roof or the wall challenging.

    Aside from the clear water trickling from the source, there are a few clues to check for to assess whether or not it has an internal leak. These indicators include peeling paint or wallpaper on your walls, damaged or warped ceilings or walls, a musty odour, or mould. If you see any of these issues growing in your home, it is definitely time to contact a local professional plumber.

    There is a risk that leaks are causing gyprock damage, and in more severe cases, the structure may be damaged. Another issue that may be related not just to your home but also to you personally is your health. Mold grows in dark, wet areas like those found in your walls or beneath your floors. A leaking pipe is a great environment for mould to grow, but the consequences for your family's health are severe. Mould grows quickly in any wet environment.

    Signs Of A Water Leak Inside Your Wall

    How To Detect Leaks Behind Walls

    Water leaking is a serious issue. Because moisture promotes mould growth, if not addressed immediately, they can cause damage to both your property and your health. Unfortunately, you won't always be able to detect whether you have a water leak until it has cost hundreds or even thousands of dollars in damage. As a result, it is critical to pay close attention. The steps below can assist you in locating a water leak inside a wall: The following are some of the unmistakable indicators of a water leak:

    • Spots of colour Water damage from leaking water pipes inside walls can cause discoloured spots to emerge.
    • Mold in areas you would not have expected to find it — It should come as no surprise to find mould in wet areas such as bathrooms. It's very possible that we've all seen it at some point in our lives. The presence of black or brown mould in other parts of your home, on the other hand, may signal a pipe leak.
    • Damp areas; a moist wall may suggest a pipe leak. However, keep in mind that the source of the leak may not be directly behind the moist spot. Water from leaking pipes may seep out of the pipe and continue to migrate down the line until it comes into contact with your drywall.
    • Paint or wallpaper that is peeling
    • Floor or ceiling damage, such as warping or discolouration - Is your home's drywall, ceiling, or floor warped? Does your floor have a spongy feel to it when you walk on it? These are all indicators of a water leak.
    • A musty odour - Even if there is no visible sign of water damage, this does not mean that it did not occur. Sometimes the aroma alone is enough to wake you up.
    • Have you ruled out the possibility that the pools of water are the result of faulty appliances? You may have a broken water pipe if this is the case.
    • Dripping water sounds - Do you hear a sound similar to dripping water when you switch off the shower or the faucet? It is probable that one of your pipes is leaking.
    • A large water bill is insufficient evidence to locate the source of a leak. Nonetheless, this is a strong indicator that you most certainly have one.

    Causes Water Leaks Inside A Wall

    Plumbing system pipes are often concealed within a building's walls. This is done because exposing the piping would make it more vulnerable to damage and ugly. If the pipe were to break or develop a slight puncture for any reason, the water would continue to slowly leak out. This would not be the case, however, because the pipes were hidden behind the walls and beneath the floors. Water leaks in a wall can occur due to a number of circumstances, including the following:

    • The weight of the concrete causes the weak plumbing to break over time because it cannot support the weight of the concrete.
    • Lines and residential sewer pipes that freeze and burst due to excessively cold or hot conditions
    • External forces are wearing down the plumbing system, which might lead to punctures.
    • Hard water can erode metallic pipes in homes that are more than a few decades old, causing them to leak.

    It is critical to find a solution as soon as the issue is detected, and this should be done regardless of what caused the pipe to break in the first place. A moist wall is one of the warning indications that there may be a water leak inside your walls.

    Wet Spots On The Wall

    When wet spots appear on the walls of a structure that is not currently under construction, this is one of the signs that water is seeping somewhere in the plumbing network. Another sign is if you begin to hear water dripping from the ceiling. Because stone and concrete have a low ability to absorb water, it does not take long after a leak for water to begin seeping through the wall, giving the wall the illusion of sweating.

    Mould Formation

    Mould development in specific places of the home, notably on the walls, is the second and most common symptom of a water leak inside one of your home's walls. Mold can only grow in situations that meet particular needs, the most important of which is moisture; hence, if mould is growing on the walls, there must be a source of water allowing this to happen.

    Peeling Paint

    When the paint around a leaking pipe starts to flake, it's another sign that there's a leak someplace else in the pipe. The bulk of paints used in home building are water-based and do not stand up well to moisture. This means that as soon as a wall comes into regular touch with moisture, the paint begins to disintegrate. The presence of water in the environment may also cause the wooden components, such as the fittings and other boards, to deteriorate.

    Unexplained Hike In The Water Bill

    When there is no evident leak in the home and you have not recently installed a new item that uses an excessive quantity of water, but your water bill continues to grow, this is another simple way that may be used to successfully detect whether or not the home has a leak.

    The Process Followed To Find And Fix The Leak.

    If you contact a professional plumber about a probable leak in the wall, they will most likely ask you why you believe there is a leak. This is because there is a high likelihood of a leak. They will next decide whether or not to visit the residence to determine whether or not there is cause for concern. They may attempt to determine the source of the leak in one of the following ways:

    • They will use a moisture metre to inspect the wall and determine the areas that have absorbed the most moisture before beginning the drying procedure. In most circumstances, the water concentration will be highest in the area geographically closest to the source of the leak.
    • They may also use an infrared camera to locate the source of the leak and the chilly location where it is located. The location of the leak will have a temperature that is many degrees cooler than the surrounding area. An infrared camera, which a plumber uses to locate the source of a leak, can detect the difference in heat.
    • When all other methods have been exhausted, cutting through the wall to look for the leak is often the last resort. The top plumbers take great pride in their ability to discover leaks without dismantling any component of the home's design. If none of the previous ways are successful, they will carefully open up the walls, locate the source of the leak, and then repair it.

    Detect Water Leaks In Walls

    The majority of water leaks are caused by broken plumbing, but leaks can also be caused by rainfall seeping down inside the walls or a cracked and leaking foundation. These two scenarios are both plausible. Leaks that go unnoticed for an extended period of time can cause significant structural damage to your walls as well as catastrophic mould concerns. Look for obvious indicators of water damage, such as peeling paint or wallpaper or discoloured spots, to identify whether or not there are leaks in the walls. A musty odour in the house could be a symptom of a water leak. Using a water metre or drilling holes in your walls are two options for precisely locating the source of a water leak. Roof Repair & Restoration Systems is Melbourne's go-to company for roof guttering due to their years of experience.

    Knowing When You Have A Leak In A Wall

    Look for pools of water that have stood still close to walls. This is the most straightforward method for determining whether or not there is a water leak in the walls of your home. If you discover a carpet in a particular section of your home that is noticeably drenched or if you see that the floor in this region is consistently damp, you can be certain that water is coming in through a wall there.

    • Wet flooring is more likely to be found in the vicinity of large machines that require the use of water, such as the washing machine and the dishwasher, or in the vicinity of the sink, toilet, or shower in the bathroom.

    Examine a wall to see whether it has any discoloration. If a wall has water leaking into it from the outside, the exterior surface of the wall will ultimately get discoloured as a result of the water. Look for areas on the wall where the surface — whether it is wallpapered, drywall, or even wood — is slightly washed out or has a lighter colour than the areas that surround it.

    • There is a good chance that the discoloration will have an uneven shape.

    Check the texture of the wall to determine whether it has changed. There is a good likelihood that walls with water leaks behind them may develop a bubble-like texture. As a result of the water's action, the paint or wallpaper will buckle and twist, forming rips or bubble-like formations as the water distorts its normal texture.

    Drywall that has been wet with water will appear to sag downward. Water behind your drywall may also be indicated by the sight of small bubbles or drooping areas.

    • Advanced leaks in walls may also give the impression that they are tilting outward. When dry wall becomes saturated with water, it will eventually buckle under its own weight.
    • Keep an eye out for any mould or mildew that may be present.

    If there has been a leak in the wall for an extended period of time, mould may be growing within and on the wall. Mold appears as a dense cluster of black or brown patches in its early stages. Even though you can't see mould growing inside the walls, there's a strong likelihood it's already there because the leak wet the walls.

    • Mold can cause allergic reactions and lead to the emergence of other potentially serious health problems. If you see mould forming on a wall, remove the mould first and then repair the leak in the wall.

    It is critical to be aware of any musty odours. If a leak is occuring behind a wall and cannot be seen, you may be able to detect it using your sense of smell. Because the water that seeps into the walls never has a chance to dry and dissipate into the air, the walls will begin to emanate a damp and musty odour.

    • Walls that smell musty are usually accompanied by other symptoms of a leak (e.g., discolouration). This is not always the case; occasionally, a fragrance is the only indication that there is a leak deep within a wall.
    • It is possible for thick drywall to absorb water (in the same way that a sponge does), thus disguising any visual indications of a leak.

    Look for dripping noises. Even if there is no evident indication of damage caused by the leak, you can still detect it in your home. Pay special attention in the initial few seconds after flushing a toilet, turning off the sink, or turning off the shower. If you hear a quiet dripping sound coming from a nearby wall, it could be the result of a leaky pipe.

    • The sound of dripping will be accentuated by more modern pipes made of PVC plastic pipe, making it simpler to notice. If your home is older, there's a strong chance you won't be able to notice a leak in your iron pipes.

    Keep an eye on the expense of your water bill. If your walls are allowing a significant volume of water to enter, the total amount you pay for your water bill each month will rise. For example, the Environmental Protection Agency (EPA) recommends that a household of four not use more than 12,000 gallons (45,000 L) of water per month during the winter. If your household is using a lot more water than this and you're not sure why, it could be due to a leak.

    • Although this will not tell you where the leak is, it will tell you whether or not it is coming from the wall.

    Determine whether the leaking water is caused by a plumbing issue. First, turn off all of the taps and other water-using appliances in your home, and then record the reading from the water metre. Allow approximately three hours. Check the water metre again; if the amount of water consumed has increased, you will know that the leak is coming from within the house's plumbing.

    • If the water metre reading hasn't changed in the last three hours, the leak isn't originating from your plumbing. It could be entering through a hole in your roof or one of your walls, or it could be entering through the basement walls.

    Examine the eaves and downspouts for obstructions. If the source of your water leak is not the plumbing, debris may be blocking your home's eaves or downspouts. If you don't have a downspout for extra precipitation or snowmelt, it will eventually seep through your roof and walls, causing leaks. If your eaves or downspouts become blocked with debris, such as pine needles or leaves, you should clean the obstruction to allow water to flow freely again.

    • Even if you haven't seen any water leaks in your walls, you should inspect your home's eaves and downspouts once a year to ensure they aren't clogged with debris.

    Examine the foundation walls for signs of leaks. Water may enter your home via the foundation walls if the conditions are just perfect. It is uncommon for these leaks to be caused by a plumbing problem. When water seeps into the foundation walls, it will eventually pour into your basement, causing the walls to fracture and leak. Most foundation wall leaks are repaired using one of two approaches.

    • From the outside, excavating a trench all the way around the foundation and then caulking and sealing the entire subsurface area of the foundation with a barrier and sealant.
    • On the inside, remove any damaged studs and drywall before filling the fissure with epoxy.

    Pinpointing The Leak’s Location

    how to detect leaks behind walls (2)

    Check the dryness of the internal walls with a moisture metre. A moisture metre is a device that, when pressed against a wall, provides an accurate reading of the amount of moisture trapped within that wall. If you suspect a leak in a curtain wall but are unclear of the exact location, place the moisture metre in five or six different areas on the wall. The location with the most moisture is the one most likely to be the source of the leak.

    • A large hardware store or a store specialising in home renovation should sell or rent a moisture metre. Qualified home inspectors frequently utilise the aforementioned gadgets in the course of their work to discover leaks and wet walls.

    An infrared camera can be used to locate the draughty area of a wall. Infrared cameras detect heat and can provide an accurate estimate of a wall's temperature. The temperature of a leaking and damp wall will be lower than the temperature of the surrounding wall. By aiming an infrared camera at a leaking wall and observing the results, you can identify which area of the wall is the coldest. This section of the wall will be the one closest to the leak.

    • Warm objects will appear in red or orange when caught by an infrared camera, whereas colder items would show in blue or purple.
    • You may be able to rent an infrared camera from a professional contractor, a home improvement store, or a company that offers photographic equipment.

    You'll need to cut into the drywall to figure out where the leak is coming from. With a utility knife, score a line about 10 inches (25 cm) long into the drywall where you notice visible signs of a water leak. This will assist you in locating the source of the leak (mould, discoloured drywall, etc.). Then, using a drywall saw, make a cut along the line you just scored. Make sure the hole you make in the wall is large enough to fit your head inside. Insert your head through the wall and gaze around until you identify the cause of the problem. Make the hole larger so that you can insert a flashlight if necessary to improve your visibility within the wall.

    • In many circumstances, the leaky section of the wall is not directly in front of the pipe or fixture that is producing the leak. Water may drain along the exterior of pipes in your walls or drop many feet down the interior of your walls before the obvious signs of a leak become noticeable. These two scenarios are both plausible. A utility knife and a drywall saw should be available for purchase at your local hardware shop.

    6 Genius Tips to Help You Find Out Where That Leak Is Coming From

    1. Check for Wall and Floor Abnormalities. Luckily certain clues may indicate the probable source of your leak. 
    2. Monitor Your Water Meter. 
    3. Inspect the Yard. 
    4. Check Faucets. 
    5. Try the Food Coloring Trick. 
    6. Check the Toilet Handle.

    Pay close attention to the wall texture. Peeling paint is a prime indicator of moisture problems, along with warping or buckling surfaces. Push on the wall slightly to see how it feels. Moisture-damaged drywall will feel soft and spongy, while wood-sheathed walls may feel slightly solid even with a moisture problem.”

    A thermal imaging camera cannot “see” moisture in walls, but it can detect subtle temperature differences and patterns that reveal the existence of water. Moisture is one of the most difficult issues to detect in a building - the signs are subtle and easy to miss until water starts dripping from the ceiling.
