How Do You Tell If You Have Moisture In Your Walls?

It is difficult to conceptualise what life would be like without water. Even within your home, it's inevitable. Humidity is a measurement of the amount of moisture that is included in the air, and it is produced when the moisture from things like running baths, boiling water, breathing, and even the elements that make up your house mingle with the air outside. However, using the appropriate building methods can help prevent moisture from entering your home through the walls. Are you interested in having your roof replaced? Roof Repair offers a diverse selection of roofing services, and you can learn more about them here.

The external walls are protected from moisture by a moisture barrier and siding, whereas the interior walls typically have a second moisture barrier installed underneath the sheathing. With the majority of instances, this will be sufficient to prevent the wall material from becoming soaked in water. In the event that there is a leak, the water can quickly soak the wall, which can lead to the growth of mould or decay. To determine whether there is moisture present inside the walls, conduct manual testing first and then move on to using moisture metres.

Take a close look at the surface of the wall. Be on the lookout for discolorations on the surface, such as yellowing material, circular brown spots, or black discolorations that frequently look like fuzzy growths. These are all signs of the presence of mould and mildew. It is important to pay great attention to the texture of the walls. In addition to warping or buckling surfaces, peeling paint is a leading indicator that there may be a problem with moisture.

Try giving the wall a mild tap to get a sense of how it responds. Drywall that has been harmed by moisture will have a spongy and squishy texture, but walls coated in wood may still feel slightly firm even when there is a moisture problem. When the surface of the damaged wood is scraped with a butter knife, screwdriver, or another similar tool, or when the surface is probed into gently, the damaged wood is often revealed.

In order to determine whether or not the wall is damp, smell it. When the inside of a wall becomes damp, it creates an environment that is ideal for the growth of mildew and mould because it is dark, it is moist, and there is a plentiful supply of food available for the fungus. When there is a greater amount of moisture present, mould and the subsequent decomposition of the wood develop much more quickly. If the wall has a musty odour, this is an indication that there is a problem.

It may be necessary to remove the faceplate from a wall outlet in order to obtain a better look at the interior of the wall and, as a result, more rapidly locate the source of the problem.

Drill two holes into the wall, each measuring approximately 3/16 inches in diameter and spaced approximately 1 inch apart. Either working from within the house or working from outside the house is a valid option. On the exterior, carry out a drill job that is just deep enough to pass through the siding but stops short of the outer wall sheathing. From the interior, drill your way through the wall, through the vapour barrier, and through the insulation.

Place the probes of a probe moisture metre into the holes that were made in the material. After turning on the metre, read the moisture content display while keeping in mind the guidelines provided by the manufacturer. If required, make adjustments to the probes in order to obtain consistent readings and reliable results. It is helpful to take a few readings at a time and space them out over a period of time; for example, three readings in a half-hour.

Check the results against the recommended amount of moisture. It is impossible for there to be zero moisture; even the wood that is used to construct a house includes some degree of moisture. The values often fall somewhere in the range of 7 and 13 percent moisture. It's possible that somewhat higher readings are typical for your home, but readings that are significantly higher demand prompt attention.

If visual inspection and mechanical tests indicate that the moisture levels inside your wall are normal, you should fill in the test holes. Caulk made of silicone, either coloured or transparent, can be squirted into the hole from the outside to seal it and make it watertight. To patch up any holes on the interior of the home, you can use wood putty, spackling compound, or drywall tape. If, on the other hand, you have a problem with moisture, you might have to rip off the wall sheathing in order to restore the interior in the suitable manner.

One of the most essential aspects of preventative home care is ensuring that moisture is kept away from the structure of your home.

• If you don't already have rain gutters, you should instal some now. This will move water away from the foundation, which will assist to reduce the likelihood of the slab cracking.
• At the very least twice a year, you should clean the leaves out of your rain gutters to prevent water backup, which can lead to rot in gutters made of wood and rust in gutters made of sheet metal.
• If the gutter drain pipes are clogged, you should use a hose to attempt to flush the debris down them. In the event that this does not work, you will need to use a plumber's snake to remove the debris that is clogging the gutter drainpipe.
• Make the necessary adjustments to the sprinklers in your yard so that they don't also water the grass and the garden around your house. Wet wood can rot and also attracts termites that feed on wet wood.
• It is important to routinely check the washers on your hose and outdoor faucet and to replace them if necessary in order to avoid water from leaking and causing damage to the foundation of your house.
• Every few months, you should go up into the attic to check for roof leaks in order to prevent water damage to the ceilings and walls that can be caused by rain.
• When you shower, turn on the ventilation fan in the bathroom or open a window to prevent moisture, which can lead to the formation of mould and mildew.

Causes Wet Walls Inside Of The House

It's not hard to wrap your head around the science behind moisture in walls. It occurs when there is an excessive amount of moisture pouring into your house, but there is nowhere for it to go. Inadequate drainage, leaks, and condensation are often the most common sources of moisture problems, as was described above.

When you want to remove moisture from the walls of a building, it can be difficult to know where to begin. Because this is such a prevalent issue, we have compiled a list of some useful solutions that will assist you in resolving it and preventing the accumulation of moisture.

Have you ever pondered the reason behind why your walls are damp and full of moisture, particularly during the colder months? You might put the blame on the significant gap in temperature that exists between the air within and the air outside. It promotes the formation of condensation as well as moisture in the walls and windows.

In addition to this, floods, leaking pipes or roofs, insufficient insulation, and other factors can cause a significant amount of water to build up inside your walls, which promotes the growth of mould and stains drywall.

The wood that supports the structure could decay, and the drywall in your walls could swell. In the event that moisture penetrates your insulation, you might expect it to become ineffective. As a direct consequence of this, the amount that you spend on your heating and cooling will skyrocket.

A residence that has been damaged by water presents significant dangers to your health and can ruin the structure of your property.

As a result, you need to move quickly in order to prevent this moisture from causing damage to the structural integrity of your building, leading to the growth of harmful moulds and fungus, or causing allergic reactions that could prove fatal.

Are you thinking of making significant changes to your house in order to fix the problem with the moist walls? Use our cost estimate tool, which is completely free of charge, to get an idea of how much it will set you back.

When looking to buy a home, it is critical to conduct a thorough search for any places that could be ill-equipped to handle adverse weather conditions such as heavy precipitation and freezing temperatures. You won't want there to be any dampness in the construction of the house if at all possible. This can result in the walls becoming severely damaged.

As a general rule of thumb, the chance of seepage increases proportionately with the age of the house. In spite of the absence of a damp proof course (DPC) and the absence of a musty odour or appearance, there is almost certainly an excessive amount of moisture present.

3 Warning Signs You Have A Moisture Problem & How To Verify It

The presence of unwanted moisture is a problem that may be seen in many homes across the United States but is frequently overlooked. A small amount of extra water in the wrong location can cause a multitude of other issues, including the formation of mould, the presence of bug infestations, and the weakening of building materials.

In many instances, moisture issues in houses or other structures are simple to miss until they have progressed beyond the point where they can be easily repaired. This can lead to significant and expensive structural damage. It is imperative to identify these issues as soon as possible in order to reduce both the scope of the harm and the associated costs. But how exactly can you determine whether or not there is a problem with moisture in the first place?

The following are some of the warning indicators that homeowners should keep an eye out for in their homes:

Musty Odors

Strong odours of mustiness are one of the indicators of a moisture issue that people run into the most commonly. This olfactory warning sign is a strong clue that there is water damage somewhere nearby. The water damage could be in building materials that are concealed from your immediate view, such as the insulation behind your walls or in a crawl space that you may have difficulties reaching without assistance.

This odour is frequently brought on by the growth of bacteria and mould in a dark and chilly environment, both of which thrive on the presence of excess moisture. If the mould is allowed to grow unchecked for a sufficient amount of time, its spores can become hazardous to one's respiratory system, and the region that has been infected may begin to show visible signs of decay. The practise of utilising highly-engineered coating solutions in order to "restore" an existing roof deck to an almost brand-new condition is referred to as roof restoration. Roof Repair Roofing Systems is the company that will take care of it for you.

Dark Patches in Building Materials

The emergence of dark patches in walls, ceilings, and other surfaces is one of the most evident signals that there are problems related to water in any construction. [Case in point:] When water penetrates building materials, it has a tendency to darken the appearance of the materials by making them appear darker.

After a severe storm, it is common for homeowners to find these dark spots in their ceilings, which is an indication that their roof has been damaged. Homeowners may also find these dark patches in their walls if there is a broken or leaking pipe there.

Gatherings of Pests

Pests, such as ants, cockroaches, rats, termites, and wasps, are not exempt from the requirement that they have access to water in order to survive. A sudden increase in the number of pests in your home may be an indirect indication that they have discovered a source of water that is suited for them in your residence. Naturally, other nutrient sources, such as open food containers, uncovered garbage bins, and the like, can also attract pests; therefore, it is essential to take into consideration whether or not there are any nearby food sources of this kind.

Prevent Moisture In Walls

Ventilate your home properly.

Ventilating your home is the single most critical thing you can do to significantly reduce the amount of moisture that accumulates there. Did you know that the production of moisture in walls can be caused by such mundane human actions as breathing, bathing, cooking, and tumble drying, among other things?

The fact of the matter is that all of that water needs to go someplace. If there is no way for it to leave your property, it will collect within.

We are not requesting that you fully alter your routines and way of life, but you may, of course, vent your home in order to get rid of the dampness. Particularly your kitchen and your bathrooms, if you can.

Check to see that these vents lead directly outdoors rather not into your attic, as the moisture in your attic will result in more severe issues. Keep in mind that in order for a vent to function, it must first be turned on. On the market, you can find a variety of vents, some of which even come with timers or moisture sensors to ensure that they operate for a sufficient amount of time and remove all of the extra moisture from the space.

A helpful hint is to check for black mould on the ceiling of your bathroom or around the window frames. It is an indication that the water vapour was unable to leave, and as a result, you need to take steps to fix the problem.

Improve your insulation

Installing double-pane windows, which have two separate panes of glass, is a tried-and-true method for warding off an excess of moisture. This will result in a significant improvement to the insulation and will assist to reduce the amount of heat that is lost. In the event that you are considering having new double glazing installed, make sure to obtain trickle vents and always leave them open. The wet air has a chance to escape through these vents that are located at the top of the windows. You are free to disable them whenever it is most convenient for you.

Install exhaust fans

Install a ventilation fan in your bathroom, and make it a habit to turn it on whenever you have a hot shower or bath. This will ensure that the air is dry and avoid an excessive amount of moisture from building up on the walls. Also, if your bathroom has a tiled floor, you should constantly keep a close look out for any grout that may be present.

These days, there is a wide variety of commercial fan chandeliers available to buy at rates that are reasonable. The humidity levels in the residence are successfully lowered as a result of the use of these fans, which draw all of the dry air inside.

Get a dehumidifier

A dehumidifier removes all of the moisture from the air, so reducing the risk of mould growth and preventing dampness. If you have a portable model, you can take it with you from room to room, leaving it for approximately 24 to 36 hours in each location, whenever you feel the need to do so.

Cupboards, caravans, sheds, windowsills, and lofts are all suitable places for a compact dehumidifier to be placed.

If you use a humidifier during the winter months, you should make sure there are no areas of the house that are sealed off where the humidity level is particularly high.

A dehumidifier can even help dry your clothes indoors by drawing the moisture out of damp clothing and sucking it into the machine.

Use vapor retarders 

The use of vapour retarders is an effective strategy for lowering the amount of moisture that spreads through the structure via the ceilings, floors, and walls.

What exactly is a vapour retarder, though?

Paints, plastic sheets, and metallic foils are all examples of vapour retarders, which are materials that have been subjected to a particular treatment that helps to reduce the amount of water vapour.

The amount of water vapour that is able to pass through a substance is called its permeability, also abbreviated as perms. The perm value should be as low as possible for the vapour retarder to work effectively.

Determine whether moisture is more likely to be travelling into or out of your house, as this will determine the type of vapour retarder you should use. If moisture moves in both directions for a large portion of the year, you might wish to altogether forego using a vapour retarder in your structure.

Keep control of mould growth.

Condensation, and consequently mould, will tend to gather in certain areas of your home more commonly than in others. These might be hidden behind huge pieces of furniture, in the corners of the room, beneath the window or on its frame or sill, or even inside closets and cabinets.

Inspect the area for any signs of mould, and if you find any, remove it by wiping it down with a moist cloth or spraying it with a mould remover. Bleach that has been diluted with water also performs quite well. You can check out what else is available at the grocery store or the hardware store in your area.

It is crucial to get rid of damp and mould since damp walls can have negative effects on your things as well as your health.

Redirect excess water away from your house

If you take care of your roof and keep it in good shape, you may eliminate any entry point for rainfall into your house. In addition to that, you should make sure that your home has a larger overhang so that the rain won't get on your walls and windows.

Do you want another suggestion to keep rainwater away from the walls of your crawlspace or basement? By establishing a slope all around your home, you can ensure that any water that runs off your roof will flow away from your structure. In order to solve difficulties with surface water, you might have to reroute the downspouts on your home or build French drains.

In addition to this, check to see that any condensate that drips from your air conditioner is correctly channelled so that it drains away from your home.

When it comes to crawlspaces, you can put thick plastic sheets on the floor as a preventative approach to protect any moisture in the ground from entering into your property.

For the same reason, you need to ensure that all watering systems for your lawn or flower beds do not flood the ground near the house.

Taking down a wall: Costs and considerations

Take care of all the leaks. If you want to prevent moisture in walls, addressing water leaks is crucial. Most leaks are caused by plumbing difficulties. A leaky bathtub, sink, or water-wielding appliances such as washing machines and dishwashers are generally the culprit.

Furthermore, water can sneak through roof penetrations such as skylights, vents, or chimneys – generating moist walls.

You need to pinpoint the source of the leak. If you’re unable to, engage an expert and get the problem repaired. Don’t attempt a DIY with damaged pipes, flashing, or gutters. This kind of sophisticated task will require the talents of a plumber or a roofer.

Tip: While you are showering, check the caulking around your tub or shower to make sure that water is not leaking into your walls or floors.

Install wide windows

When you think about venting to remove moisture, you should also consider where the replacement air will come from and how it will get into your house. Keep your interiors well-ventilated by adding large windows and doors. Keep them open to let in enough light and air. Don’t allow your window treatment impede natural light. Sunlight helps keep the indoor air at a healthy moisture level without increasing your energy expenditures.

Choose your construction material wisely.

There are significant differences in how different materials absorb and release moisture. A brick wall, for instance, is more likely to allow moisture to pass through it (and it also stores moisture), in contrast to aluminium siding, which does not.

In terms of the materials used for construction, it is recommended to use concrete rather than plaster-based interiors whenever possible. The latter results in the penetration of moisture. Install eaves on the outer walls of your home.

You also need to check to see that your kitchen has adequate air vents and conduits for the air to flow through. It is important to avoid putting any large or heavy furniture in front of the vents. Additionally, you should equip both your kitchen and bathrooms with quality extractors. Choose hardwood pieces that have not been stained or varnished.

A few more preventive tips

• Reduce the quantity of indoor plants you have because they not only give off water vapour that makes the air more humid but also pull moisture out of the air that they are in.
• Always do the laundry outside in the fresh air.
• Make an investment in downspout and gutter systems of high quality.
• Use impermeable films or geotextiles to protect the foundations of a building.
• Construct concrete foundations that are watertight up to a height of forty inches.
• To a height of at least 20 inches, the exterior of the walls should be treated to repel water.
• It is recommended that you add a barrier against humidity, which typically consists of a layer of polystyrene that is glued to the plasterboard. This barrier should be added to the wall coverings that are located along the perimeter of the room.
