Our comprehensive range of exterior coating and parging services encompasses the following essential steps:
Our skilled technicians are well-equipped to handle a wide array of parging repairs.

We remove loose material to ensure a solid bond, protecting your property’s structural soundness against seasonal moisture.
When it comes to applying new parging, we take immense pride in delivering flawless visual results. Our highly skilled team employs industry-leading trowel techniques and premium masonry materials to ensure a smooth, uniform finish. This provides your foundation walls with a clean appearance that enhances the overall aesthetic appeal of your residential property.
We acknowledge that each home is unique. Our dedicated team will thoroughly assess your foundation walls, engage in discussions to understand your exterior design preferences, and provide expert recommendations. We tailor the texture and application approach to achieve your desired look while maximizing the protective benefits for the concrete beneath.
A lasting parge coat relies entirely on the quality of the surface preparation. We carefully clean the foundation, wire-brush loose debris, and apply appropriate bonding agents when necessary. This meticulous preparation prevents premature peeling and ensures the new cement mixture adheres perfectly to the existing poured concrete or block wall.
Choosing to update your exterior foundation is not solely an aesthetic decision; it is a practical step in routine home maintenance. The freeze-thaw cycles typical of our region can be harsh on exposed concrete. Small pores in unfinished poured concrete or the mortar joints of block foundations can trap wind-driven rain and melting snow. Over time, freezing temperatures cause this trapped water to expand, which may lead to surface spalling, micro-cracking, and the gradual deterioration of the concrete face.
Implementing reliable parging services in London Ontario provides a sacrificial layer of mortar that takes the brunt of this weather exposure. Instead of the structural foundation degrading, the parging coat acts as a breathable barrier. If minor surface damage occurs over a decade of severe weather, it is significantly easier and more cost-effective to repair a section of parging than to address deep structural deterioration in the foundation itself.
By choosing West Key Builders for your masonry needs, you can expect nothing short of exceptional craftsmanship, meticulous attention to detail, and an unwavering commitment to ensuring your utmost satisfaction.

Parging is a specialized mortar coating applied to the visible, above-grade portion of a home’s foundation. It is primarily made from a blend of cement, sand, and water. Its main purpose is twofold: it provides a smooth, aesthetically pleasing finish that hides formwork marks and rough concrete, and it acts as a breathable barrier that protects the underlying foundation wall from direct exposure to rain, snow, and ice.
Flaking or cracking usually occurs due to moisture infiltration and the natural freeze-thaw cycle. When water seeps behind the parge coat and freezes, it expands, pushing the parging away from the foundation wall. Other common causes include poor initial surface preparation, using the wrong cement mix, or the natural settling of the house over decades. Regular inspections can catch minor flakes before they spread.
No, it is highly recommended not to apply new parging directly over a loose or heavily damaged layer. For the new mortar to adhere properly and last, we must chisel away any deteriorated, hollow, or flaking sections. We thoroughly wire-brush the exposed concrete to remove dust and debris before applying a bonding agent and the new parging mix to ensure a permanent structural bond.
Parging is an exterior, above-grade treatment designed for surface protection and aesthetics. It is not a waterproofing membrane and will not fix an active basement leak or structural foundation failure. If your home has deep structural cracks or active water intrusion below grade, those issues must be addressed with dedicated foundation repair methods before applying a cosmetic parge coat.
When properly applied to a correctly prepared surface, a high-quality parging job can last 15 to 20 years or more, depending on environmental exposure. Homes with proper roof drainage, effective eavestroughs, and grading that slopes away from the foundation generally see their parging last significantly longer, as these factors keep excess moisture away from the concrete surface.
Yes. West Key Builders is committed to delivering lasting quality. We provide a 2-year warranty for new concrete works and new parging applications. This warranty reflects our confidence in our careful surface preparation, our choice of premium mortar materials, and the rigorous troweling techniques our masonry team employs on every project.
Absolutely. Parging is an excellent solution for both foundation types. On poured concrete, it hides tie-hole marks, honeycombing, and rough aggregate lines. On concrete block (cinder block) foundations, parging completely covers the mortar joints and block faces, transforming a highly textured, utilitarian wall into a smooth, seamless architectural feature that drastically improves curb appeal.
We are happy to provide localized patch repairs if only a small section of your foundation has been damaged by snow shovels, lawnmowers, or minor weathering. However, if the existing parging is old, faded, or widely deteriorated, we often recommend re-parging the entire visible foundation to ensure a structurally sound bond and a perfectly uniform visual appearance across the entire home.
When performing patch repairs, we utilize blending techniques to make the new mortar match the existing texture as closely as possible. However, because older parging has weathered, faded, and accumulated dirt over many years, a brand-new cement patch will naturally appear slightly different in color initially. Over time, the new patch will cure, weather, and blend in more closely with the surrounding wall.
Parging requires mild, dry weather to cure correctly. The ideal time for our parging services in London Ontario is from late spring to early autumn. If the temperature is too cold, the mortar can freeze before it cures, causing it to fail immediately. If it is extremely hot and sunny, the mix can dry too quickly, leading to shrinkage cracks. We monitor the weather closely to schedule your application during optimal conditions.
Yes, parging can be painted, but you must wait until the new mortar is fully cured, which generally takes about 28 days. It is crucial to use a high-quality, breathable exterior masonry or elastomeric paint. Using standard house paint can trap moisture inside the foundation wall, which will eventually cause both the paint and the parging to blister and peel away.
The secret to longevity is preparation and bonding. After stripping loose material and cleaning the concrete, we dampen the wall to prevent the dry foundation from sucking moisture out of the new mix too quickly. We then apply a liquid bonding agent or a slurry coat. Finally, the parging mortar is troweled on firmly, pressing it into the pores of the concrete to create a mechanical and chemical lock.
Mortar will not bond securely to a painted surface because the paint acts as a barrier. If your foundation is currently painted and you wish to have it parged, the paint must first be removed using techniques like sandblasting, grinding, or specialized chemical stripping. Alternatively, we may need to securely attach a metal lath (wire mesh) to the wall to hold the new parging in place.
A standard parge coat is typically applied at a thickness of about 1/4 inch to 3/8 inch. This thickness provides an ideal balance; it is thick enough to cover imperfections and provide weather resistance, but thin enough that its own weight does not pull it off the wall while curing. In some cases involving deep block recesses, two thinner coats may be applied successively.
While parging seals tiny drafts, micro-cracks, and mortar joints from direct wind exposure, it is not an insulating material and provides negligible thermal resistance (R-value). Its primary functions are surface protection and aesthetic improvement. If you are looking to significantly improve your basement’s energy efficiency, you should explore interior insulation or dedicated exterior rigid foam systems.
Maintenance is quite simple. The most important step is to keep water away from the wall. Ensure your gutters are clear, downspouts discharge several feet away from the house, and the soil is graded to slope downward away from the foundation. Avoid using harsh chemical de-icers near the wall in winter, and gently rinse the parging with a garden hose to remove dirt buildup in the spring.
Yes. Older concrete blocks and deteriorating poured walls often have small recesses, missing mortar, or micro-cracks that ants, spiders, and other insects can use to nest or enter the home. A solid, uninterrupted coat of parging seals these small crevices, effectively removing insect entry points and contributing to a more secure exterior envelope.
Yes. While a smooth, float-finished look is the most common request for modern homes, we can also provide textured finishes. Using different trowels, sponges, or brooms, we can create a slightly stippled or brushed texture. During your free estimate, we can discuss the architectural style of your home and recommend a finish that best complements your siding or brickwork.
Because parging is entirely exterior work, you do not need to be home for the duration of the project as long as we have clear access to the foundation walls and access to an exterior water spigot for mixing the mortar. We maintain a tidy, respectful job site and will clean up all debris and masking materials before we leave the property.
Getting started is easy. You can call us directly or use our online contact form to provide brief details about your home’s foundation. We actively work to schedule same-week appointments to respect your time. During the site visit, we will measure the foundation, assess the current condition of the concrete, and provide a clear, written estimate without any hidden fees or obligations.
