Causes of dampness and remedies of dampness in building
Dampness occurs due to existence of excessive moisture in building components. Dampness initiates mould, wood rot, as well as invitation to termite attack.
Moisture damage happens because of insufficient ventilation, roof leaks, or pond water penetration into the foundation due to choked gutters & downpipes. Presence of moisture in the home can strip paint, damage the integrity of the structure and produce health vulnerabilities for the inhabitants from mould and fungus spores.
Inappropriate drainage also leads to accumulation of excessive moisture. Sloping grades can move back water toward the home where it penetrates the foundation. Plumbing leaks and roof leaks can also result in moisture damage.
Reasons for dampness in building:
1. Moisture getting up the walls from ground
2. Rains pass through from walls tops.
3. Rain beating against external walls.
5. Miscellaneous reasons.
To get rid of dampness problems and water damage to your home, some precautions should be taken to avoid costly repairs. Given below, some vital steps to resist moisture damage to your home.
1. Cleanse Gutters and Downpipes – Chocked gutters and downpipes stop water discharging from the home. Sometimes, the rainwater overfills the gutters and pond at the base of your home. It causes infiltration to the foundation. Remove debris and fallen leaves from gutters and flush out the downpipes.
2. Examine Roof for Loose or Damaged Shingles or Flashing – Due to roof leaks water penetrates through the roof from chimneys, vent pipes and skylights. It is recommended to appointing a professional to check for signs of wear or leaks.
3. Verify Property Gradient for Drainage – Ensure the slope of the land is perfect to move water away from and not back towards. Some landscaping may be required to fix inappropriate drainage of groundwater.
4. Repair Plumbing Leaks – Pipes and fixtures are susceptible to leaks, specifically at joints where seals wear away and crack. The old seals should be changed. PVC cement should be applied to fix pipe sections firmly. Flush plumbing lines and septic tank.
5. Keep away from Over-insulating the Home – There should be perfect ventilation for the house so that the moistures can’t get stuck inside. Accumulation of moisture can create various issues like rust to wood rot. Ensure that the eaves of your attic contain sufficient airflow to get rid of these issues.
6. Check Windows and Doors for exact fitting – Settling can arrange doorways out of square and consequently gaps are formed. Window seals crack and dry out in due course penetrating moisture around the frames.
If required, change damaged or missing weather stripping, caulk gaps.
7. Appoint a Professional Building Inspector – A trained building inspector can easily detect problem areas which the average homeowner will fail to notice. By appointing a professional, one can save some very expensive repairs down the road.
8. Damp proofing course - Arrangement of damp proofing course can resist the penetration of moisture into the building structure.
