Maintaining Your Home’s Parging: Tips and Best Practices

Parging is a protective layer typically applied to the exterior walls of the basement or foundation. It not only shields your home from harsh weather but also enhances its overall appearance. However, like any part of your home, parging requires regular maintenance to ensure it remains practical and visually appealing. In this blog, we’ll dive into the essential tips and best practices for maintaining your home’s parging, ensuring longevity and durability.

Understanding Parging

Before delving into maintenance tips, it’s vital to understand what parging is. Applying a thin layer of mortar or concrete mix typically composed of masonry or concrete to a building’s outer walls is known as parging. This process helps to smooth out uneven surfaces, cover potential defects, and provide a uniform look to the foundation or basement walls.

Regular Inspection

Ideally, inspect your parging at least twice a year—before and after the harsh winter season. Look for cracks, chips, or any signs of wear and tear. Early detection of these issues can prevent water infiltration, which is a leading cause of parging deterioration.

Immediate Repairs

It’s critical to take quick action if your inspection reveals any minor damage or cracks. Masonry crack filler is frequently used to seal minor cracks. However, removing the affected area and applying a new layer of parging mix may be necessary for more significant damage.

Cleaning Your Parging

Keeping your parging clean can significantly extend its lifespan. Dirt, grime, and other environmental pollutants can adhere to the surface, leading to discoloration and potential damage over time. Use a soft brush and a light detergent solution to clean the surface. Pressure washers and other strong chemicals should not be used as they can degrade the parging substance.

Avoid Moisture Buildup

Moisture is the nemesis of parging. Ensure your house’s gutters and downspouts are free of debris and operate properly to divert water away from the foundation. To stop water from collecting close to the foundation walls, you should also consider landscaping and grading changes surrounding your house.

Sealant Application

Applying a waterproof or water-resistant sealant can offer additional protection to your parging, especially in climates prone to heavy rain or snow. Ensure that you use a sealant compatible with your parging material and follow the manufacturer’s application instructions.

Professional Assessment

While regular homeowner maintenance is essential, having your parging assessed by a professional every few years can provide peace of mind. A specialist can provide a thorough examination, see possible problems that the inexperienced eye might miss, and suggest essential fixes or preventive actions.

Education and Awareness

Lastly, educating yourself about the materials used in your home’s parging and understanding the factors that contribute to its deterioration is key. Knowledge about the proper care and maintenance of parging will empower you to take proactive steps to preserve its condition.


Repairing the parging in your house is a continuous process that needs consideration and care. By using these pointers and best practices, you can ensure that your parging stays in excellent shape, safeguarding the foundation of your house and improving its curb appeal. Remember, regular maintenance, immediate repairs, and professional guidance significantly influence the longevity of your parging. Take the time to care for your parging; it will serve as a durable shield for your home for years to come.
