Damp Patch On Internal Wall After Rain? Here’s What To DoBy admin
Tuesday, 3 September 2019
Do you have damp patches on your wall? This frustrating phenomenon can be caused by a number of different factors. If it rained recently, then the patches are clustered around the windows and doors.
Damp patches are caused when water from outside seeps into the house, subsequently spreading to the other surfaces inside. Damp patches are just the beginning.
If left unaddressed long-term, a surfeit of moisture will inevitably interfere with the structure, putting your whole property on shockingly shaky foundations.
There are various signs of dampness to look out for when assessing your home for damp. These include:
– Peeling wallpaper
– Stale odour
– Visible watermarks and patches
– The furniture and walls feel damp to the touch
How Does Rain Affect Houses?
If it has been raining, and you see damp patches starting to take shape, it’s likely to be due to one of the following contributory causes:
– A tile on the roof is broken, causing leakage.
– There are cracks in the wall.
– Due to rain, the damp proofing of the foundation has been affected. In some cases, puddles get formed by the foundation.
– The insulation material is of inferior quality or non-existent.
Checking For Condensation: Say Hello To The Foil Test
Damp patches are just the beginning of a much greater, potential problem. Ultimately, moisture is slowly going to seep into the entire wall. This is not just inconvenient; in some cases, it can be hazardous to health as well-especially if starts to spawn mould and their resultant spores.
You can try a foil test to discern whether dampness has been caused due to condensation. For the foil test, you first need to dry the surface with a fan heater.
After that, tape a small piece of kitchen foil to the area in question. If the surface of the foil is wet after 24 hours, you have confirmed the reason to be condensation. You can examine the entire house to determine the exact cause of this challenge.
Can Damp Walls Be Detrimental To Health?
If left unaddressed, with mould starting to appear, then absolutely. The following are the negative effects of leaving damp unchecked long-term:
– Formation of mould spores.
– Can cause breathing problems.
– Can cause skin irritation.
– Can cause structural issues in the building in the long run.
– The mould spores release a toxin called mycotoxin. These can be toxic to the inhabitants. They can cause nausea, tiredness, and feelings of utter confusion.
What Should Be My Next Course Of Action?
The very first step to fixing something is recognising the problem. Now, the next natural step would be thinking about measures that can be taken.
Action Step No. 1: Work On Producing Less Moisture:
As it is raining, there is already a lot of moisture in the air. Do not use open pots for cooking, or leave the kettle boiling. Minimise the use of appliances that generate additional moisture.
Action Step No.2: Take Measures To Improve Ventilation:
Even if there is moisture in the house, you can ventilate the problem area, and get rid of it with relative ease. Opening windows and taking other additional measures, all play their part in curbing condensation.
Action Step No.3: Insulate The House With A Superior Insulation Material
You can get the insulation done with the proper insulation material. It provides you with the widest range of benefits out of all the listed measures.
Action Step No.4: Seek Out A Smarter Heating Solution:
You can also seek out a smarter solution for heating your home. Find an appliance that’ll not let out moisture, and keep your house warmer for longer, at the time of day when you’re usually at home.
Let’s now rate all these measures and their applicability…
You can try to reduce the use of some appliances, but by how much? We all live increasingly busy lives and are bound to slip at some point; especially when the weather gets colder. We will only be buying time instead of solving the problem.
If you live in a period home, it is already too cold to live in. If you always keep the windows open for ventilation, it will make it colder. That won’t be convenient. You cannot keep the heating system on all day. It won’t be good for the energy bills.
What Is The Most Cost-Effective Method Overall?
The answer is home insulation. Spray foam Insulation has been the best of all the approaches to deal with damp patches on walls. Why? Let’s find out…
- Spray Foam Insulation is very easy to install. It won’t matter if you live in a home with cavity walls or solid walls. As it only needs to be sprayed, it can be installed in spaces of all shapes and sizes.
- It decreases your reliance on additional appliances. You will not have to keep the heating systems or air conditioners running all day. You will save a lot of money, and get rid of dampness. Insulation keeps the temperature inside the house consistent, irrespective of the weather outside.
- It reduces airborne noise transmission, making for peaceful conditions inside.
- There would be no toxic material in the air, as spray foam insulation is an 100% water blown product.
Open Celled vs Closed Cell Spray Foam: Which Is Best For Damp-proofing?
There are two kinds of spray foam insulation: open cell and closed cell. Out of the two, open cell spray foam is a far more preferential option for homeowners than closed cell varieties. Here’s why:
- Open celled spray foam uses water blowers, whereas the closed cell variety uses HFC (hydrofluorocarbon) blowers. The water boilers are stable, and do not harm the environment.
- Open celled spray foam is less costly than closed cell foam. It is incredibly efficient, and the best option for keeping in budget.
Spray foam has a much longer life than any kind of insulation, performing for the life of the building. You will have a peaceful life, and do not have to worry about the damp patches reappearing at a later date.
