7 Warning Signs You Need Parging Repair ASAP

The foundation of your house is the silent protector, a solid foundation that can withstand any elements while supporting the whole structure. Like any other component of a home foundation can become damaged as time passes. Parging, the outer layer of mortar put on the walls of foundations, plays an essential function in defending the foundation from damage caused by moisture and in ensuring its structural solidity. But, it may also be prone to age and wear, making your foundation in danger.

It is important to be proactive when it comes to parging repair. It is vital to avoid expensive foundation problems later on. Here are seven warning signs that shout “Parging Repair ASAP”:

1. Cracks in the Parging

Cracks are the most frequent indicator of the failure of parging. Cracks may be hairline thin or large and spherical. The smallest cracks may appear insignificant however they could allow moisture to penetrate the foundation, causing greater destruction.

  • Look for: Hairline cracks, large cracks, spiderweb cracks running in multiple directions.
  • What it means: Cracks signify a loss in bonding between the parging and the wall of the foundation. It could be due to the foundation’s settling, shrinkage of the material used for parging, as well as exposure to temperatures that are extreme.
  • Action: Don’t leave cracks untreated! Plan a competent inspection to evaluate the extent of the damage and decide the excellent option to repair the parging.

2. Crumbling or Flaking Parging

In time, parging may become hard and start to crack or crumble away. The foundation wall is exposed beneath, making it vulnerable to freeze-thaw and water damage (common in areas that experience severe winters).

  • Look for: Pieces of parging material that have separated off the walls, leaving a foundation below.
  • What it means: Parging that is flaking or crumbling is a sign of deterioration that is advanced. It is crucial to take care of this issue before devastation to the foundation becomes serious.
  • Action: Contact a certified foundation repair professional for parging repair as soon as possible.

3. Hollow Sound When Tapped

A hollow sound produced when tapping the parging using a mallet or screwdriver can signal a gap between the parging’s surface and wall of the foundation. The separation can create pockets of air, which can compromise the ability of the parging to protect the foundation.

  • Look for: A dull, hollow sound rather than a solid thud when tapping the parging.
  • What it means: This is a sign of a weakening of the bond between the foundation and the parging and allows moisture to penetrate the crack and cause damage to the wall of the foundation.
  • Action: Schedule the time for a well-qualified inspection to assess the extent of the separation, and obtain suggestions for parging repair.

4. Water Stains or Efflorescence

Stains of water that run through the walls of the foundation or powdery white deposit (efflorescence) in the parging’s surface are signs of moisture issues. Water can leak through cracks or holes in the parging, which can cause these indications.

  • Look for: Brownish or greenish water staining on the walls of the foundation or crystal-like deposits of white (efflorescence) along the parging.
  • What it means: These indicators suggest that water is leaking into the foundation system, creating water leaks, growth of mold and damage to the foundation.
  • Action: Address the cause of the water intrusion (faulty drains, poor drainage) and plan parging repair to stop further water intrusion.

5. Leaning Chimney

Leaning chimneys can be an indication of foundation settlement. This may also affect the parging. The cracks that appear in the parging surrounding the chimney’s base can further indicate this issue.

  • Look for: A chimney that looks tilted or tilted away from the house, cracks in the parging around the chimney.
  • What it means: Leaning chimneys need immediate attention since they may damage the structural stability of the home. In addition, foundation settlement could create cracks within the convexity of the chimney.
  • Action: Call an engineer who can assess the chimney and foundation. Parging repair could be a part of the solution but it’s essential to tackle the foundation problem first.

6. Bowing or Bulging Foundation Walls

However, it is less well-known that the bulging or bowing of foundation walls are indicators of foundation weakness. The problems could create cracks that cause the parging to expand substantially.

  • Look for: Inward bowing or outward bulging of foundation walls, cracks that are large and that run across the parging.
  • What it means: Bowing and bulging walls of foundation need urgent skillful attention. These signs are indicative of structural problems that must be dealt with to avoid a possibility of collapse. The repair of the parging won’t be sufficient to solve the issue.
  • Action: Contact a foundation repair specialist as soon as possible. They will assess the situation and recommend the most appropriate foundation repair solutions, which might include parging repair after the structural issues are addressed.

7. Musty Odors in the Basement

A musty, damp odor in your basement may signal water intrusion through gaps or cracks in the walls of your foundation. The moisture could cause the growth of mold, which can pose risk to health and may cause damage to the foundation.

  • Look for: A musty, earthy scent inside the basement particularly after heavy snowfall or rain.
  • What it means: The odors of musty smells in the basement can indicate issues with moisture that could cause the growth of mold and damage to foundations. The failure of the parging system could be a reason for this.
  • Action: Find out the cause of the water and take action to stop the issue. Plan a well-qualified inspection to evaluate the foundation and the parging. Parging repair might be necessary, but it’s crucial to address the root cause of the moisture issue first.
