Residential & Commercial Foundation Parging
Parging is a cement-based mortar coating applied to the exterior of your foundation walls. It serves as your foundation’s first line of defence against water, sealing cracks and gaps that let moisture in during heavy rain and spring melt. In Ontario, where temperatures swing from +30°C in summer to -25°C in winter, your foundation is constantly expanding and contracting — and parging acts as a protective buffer that absorbs that stress. Beyond protection, parging also covers the rough, unfinished look of bare concrete or block and gives your foundation a smooth, uniform finish that completes your home’s exterior.

Common Parging Problems
Parging takes a direct hit from Ontario’s weather year after year. Freeze-thaw cycles, ground moisture, and poor original application are the most common reasons parging fails. Catching these issues early prevents water from reaching your foundation and causing serious structural damage.
Parging Pricing & Estimates
Foundation parging costs vary depending on the scope of your project. Here’s what you need to know to plan with confidence:
The price of parging depends on the size of the foundation area, the condition of the existing surface, whether old parging needs to be removed first, and accessibility around the building. Deep cracks or structural damage requiring repair before coating will also affect the final cost.
Our experienced team provides itemized estimates covering surface prep, materials, and labour — no hidden fees, just honest pricing. You'll know what to expect before any work begins.
A quick visual inspection every spring and fall catches hairline cracks and early flaking before they let water behind the coating. Addressing small patches immediately extends the life of your entire parge coat and protects your foundation for years to come.
Whether it's a planned re-parge or an urgent repair before winter sets in, our team responds quickly and gets the job done right — keeping your foundation sealed and protected.

Why Choose Professional Parging
Keeps Water Out of Your Foundation
Water is the number one enemy of any foundation. Every hairline crack and gap in your foundation wall is an entry point for rain, snowmelt, and ground moisture. Parging seals those openings and creates a water-resistant barrier that keeps your basement dry and your foundation intact. In Ontario’s climate, where freeze-thaw cycles can widen cracks in a single season, a solid parge coat is essential protection.
Protects Against Freeze-Thaw Damage
When water gets into your foundation and freezes, it expands — cracking concrete and pushing mortar joints apart. This cycle repeats dozens of times every winter in the GTA. Parging acts as a sacrificial layer that takes the brunt of this abuse, absorbing the stress before it reaches the structural foundation underneath. It’s far cheaper to re-parge than to repair a cracked foundation.
Improves Energy Efficiency
Gaps, cracks, and exposed joints in your foundation let cold air seep into your basement and heated air escape. A properly applied parge coat seals these openings, reducing air infiltration and helping your home hold heat more effectively during Ontario’s long heating season. It’s a small investment that contributes to lower energy bills.
Clean, Finished Appearance
Bare concrete, exposed block, and crumbling old parging look rough and unfinished. A fresh parge coat gives your foundation a smooth, uniform surface that ties your home’s exterior together. It’s also the perfect base for painting or sealing if you want to take the finished look even further.
