To correct the moisture problem in walls, the first thing to do it to determine the extent of the damage by visual inspection. For precise results, a moisture meter can be used.
The next step is to pinpoint the cause of the water damage and start appropriate repairs to prevent the spread of the damage.

Here are different cases of moisture damage and how to address each.

Damp Patches in Lower Walls
When the damage occurs on the lower parts of the wall, the problem is identified as rising dump. It is caused by a defective damp proof course. The problem can sometimes be attributed to poor site drainage or bad subfloor ventilation.
Fixing the problem involves improving the drainage of the site by directing water away from the building. To prevent the formation of moisture in the soil below, adequate space must be left between the soil and the floor boards.
Condensation Issues
This problem occurs due to poor ventilation and over-efficient drought proofing, which results in a buildup of moist air in the building.
The problem can be rectified by setting up vents or extractor fans in the moisture-prone parts of the building.
Damp Patches All Over Walls
Damp patches all over the walls are caused by the penetration of moisture from outside into the brickwork. This occurs through cracks and other gaps.
Preventing this involves maintaining external walls including the paintwork in top-notch condition, and sealing any gaps around door and window frames.
Roof Issues
Poor flashing or leaking gutters and drainpipes may be blamed for moisture in the top parts of the wall. These culprits are all located outside the structure which makes spotting and correcting them easy.
If any of these issues are present at your home or business, do delay in contacting Christian Brothers Restoration.
