Why Damp Proofing is Necessary
Aside from the comfort aspect, various kinds of problems will arise once you leave your home in damp conditions and are filled with mold.
Not only does it concern long-term property damage caused by rotting and degradation, but it can also affect the health of your respiratory system and other occupants of the house caused by dust mites, bugs, and bacteria.
Before these things happen to you and your family, it is better to immediately clean the mold regularly, even if it’s only a little.
Gradual cleaning, indeed, will be more cost-effective than you delaying it for years, which eventually requires you to redecorate your home.
Alternatively, consider damp proofing to overcome this situation also won’t go wrong.

How Much You Have to Drain to Damp-proof a Wall?
On average, you will need to spend $ 200- $ 2000 per wall. However, this is not a significant rule.
Apart from the size of your walls, another major factor affecting the damp proofing process’s price is the type of moisture problem you have.
Below will be discussed three types of humidity problems and the method of solving and calculating the costs you have to spend.
Condensation is a common issue that you can find in modern homes. Usually, this condition is caused by a lack of air ventilation, low room temperature, the steam from the cooking process, water from the bathroom, to droplets from wet clothes in the area of your clothes dryer.
As for the signs of a condensation issue, you will usually be able to find some moisture spots on areas such as windows, tiles, and other surfaces.
Even worse, when this condensation problem starts to seep into your walls or baseboard, mold will appear on these damp spots and make your house look bad. What’s more, this can induce respiratory problems.
· Method and Cost
To fix this, you can do DIY or call the contractor. If you decide to do this job yourself, you only need to clean your baseboard using soap or a white vinegar solution.
Besides, you can also buy a dehumidifier at an affordable price to keep your room temperature in good condition. Your average probable cost is not more than $ 50- $ 60.
Further, if the mold starts to spread over a large area, considering redecorating is the best answer. In general, this job costs around $ 100 up to $ 200.
To ensure that the condensation won’t reoccur, you need to coat your walls with a damp proofing paint such as Rust-Oleum Mildew Performance Paint.
2. Penetrating Damp
There are two types of penetrating damps.
The first is lateral penetrating damp. This type of humidity is usually caused by the existing problems with your window or door’s seals or the low quality of brickwork.
In the early stages, the lateral penetrating damp will affect your house’s external appearance because it is the part that most often gets the harsh effect of weather conditions. However, this moisture issue can slowly creep in and affect your interior’s appearance at a later stage.
On the other hand, vertical penetrating damp is caused by top-to-bottom cases, such as broken roof tiles or problems with the guttery like faulty or block.
The signs can be capricious depending on the severity of the problem. You can find water stains or droplets on your wall surfaces in normal conditions and even spot some molds.
When you start to smell moisture, you should take the tread to crack this problem immediately. This sign is an early warning of rising dampness in your home.
· Method and Cost
The primary step on this dampness is fixing the sources of the problem. For instance, replace or fill the cracks on the wall that cost about $50 or guttering replacement that needs up to $200.
For full window replacement, you need to spend about $300-$1000. Further, applying a waterproof seal or installing the damp proof membrane can prevent this problem from coming again.
3. Rising Damp
Rising damp is a condition where moisture in the soil begins to seep on the walls of your house. It usually happens in old properties with no damp proofing materials since the beginning of construction or low damp-proof sources that are no longer effective.
Apart from making the interior of your home look bad due to the presence of visible damp lines on your walls, this humidity problem can also reduce your building’s integrity.
Granted, rising damp does not display molds. Still, it usually brings out a visible mineral salt that you can even feel once you swipe a moisture area by hand.
· Method and Cost
The only way to fix this case is to inject a Damp Proof Course (DPC), which costs between $ 300- $ 450 per wall. It depends on how large the area must be repaired.
You have to retain a contractor to equipped this course.
If the mineral salt soaks on your drywall, it’s a good idea to replace it with a waterproofing bonding additive. Of course, to do this job, you will have to pay much more.
Damp Proofing vs. Water Proofing, which is better?
These two products, indeed, address two different issues in construction. The damp proofing is sufficient to protect your entire home from soil moisture. Its use has become an IRC standard to apply in all modern homes.
Meanwhile, waterproofing can protect your property from soil moisture and liquid water at the same time.
In particular, this method is highly recommended for high water humidity levels or even a combination of soil-water conditions, such as the basement.
For the cost, damp proofing may come from $4-$8, while waterproofing starts from $6-$10 per square foot.
Tips to Decorate Damp-proofed Wall
Before considering decorating the wall right after damp-proof, you must take the initial step to ensure it already dry entirely. As painting or wallpapering on the wet spot will only make your partition looks worsen.
You have to know that the installation process mostly needs three to four days for full damp proofing.
But the drying process can take up to six months if your house is affected by rising damp. Of course, this is not the primary standard.
Generally, suppose you only damp-proof one problematic wall of your house. In that case, the installation will only take half to one full day.
Meanwhile, for the drying process on the damp-proofed wall, which is intended as a preventive measure, it only takes two to three months.
The next step after you make sure that your walls’ surface is dry. You can apply a water-based primer such as Zinsser or other damp proofing products to prevent the paint from seeping into the partitions and give the best result of decorating.
Above is A to Z information relating to damp proofing you have to know. Regardless of the high price, it is a useful method you have to try to free your loving home from any distraction caused by the dampness.
