  • Maintaining your surfaces will not only enhance your home’s curb appeal but also increase their safety and functionality.

Understanding Flagstone and Interlocking Surfaces

Before we dive into maintenance techniques, let’s first understand what flagstone and interlocking surfaces are. Flagstone refers to flat, thin stone slabs that are used for various outdoor applications, such as patios, walkways, and pool decks. These natural stones come in different shapes, colours, and textures, adding a unique character to your outdoor spaces. On the other hand, interlocking surfaces feature pre-cast concrete pavers or stones that fit together like puzzle pieces. They are a popular choice for driveways, pathways, and retaining walls due to their durability, versatility, and affordability.

Understanding these materials is essential for effectively maintaining them. While flagstone is a natural stone that requires a different approach than interlocking pavers, both surfaces need proper care and attention to preserve their beauty and functionality.

Cleaning and Removing Debris

Regular cleaning is crucial for maintaining the beauty and safety of your flagstone and interlocking surfaces. Accumulated debris such as dirt, leaves, and other organic matter can increase the risk of slips and falls. In addition, debris can cause staining and discoloration on your surfaces, making them appear dull and unattractive.

The following are effective techniques for cleaning and removing debris from your flagstone and interlocking surfaces:

  • Sweeping: Regular sweeping with a broom or a leaf blower can help remove loose debris from your surfaces. We recommend doing this at least once a week, or more often during fall and spring when leaves and flowers are abundant.
  • Pressure washing: For more stubborn debris or stains, pressure washing can be an effective method. However, you need to be careful not to use too much pressure, as it can damage the surface. We recommend using a low-pressure setting and keeping the nozzle at a distance of at least two feet from the surface.
  • Mild cleaners: For particularly tough stains, you can use mild cleaners such as dish soap or a mixture of water and vinegar. Apply the cleaner to the surface, let it sit for a few minutes, and then rinse it off with water. Avoid using abrasive cleaners or those containing acid, as they can etch the surface.

It’s essential to remove debris from your surfaces promptly, as it can become embedded in the gaps between the interlocking stones, making it even more challenging to clean.

Sealing and Protecting Flagstone and Interlocking Surfaces

Sealing your flagstone and interlocking surfaces is a vital step in maintaining their appearance and longevity. At Interlocking Toronto, we recommend sealing your surfaces annually to ensure they stay protected from stains, weathering, and other potential damage.

Applying a quality sealer not only protects your surfaces but also enhances their color and texture. There are different types of sealers available, such as water-based and solvent-based, so it’s essential to choose the right one for your specific surface materials and environmental conditions.

When applying the sealer, make sure the surface is clean and dry. Use a roller or sprayer to evenly distribute the sealer over the surface, and allow it to dry completely before applying a second coat. Be sure to follow the manufacturer’s instructions for the specific sealer you use, as some sealers may require more than one coat or a different application method.

Keep in mind that sealing is not a one-time fix. Over time, the sealer will wear off, and you will need to reapply it. The frequency of reapplication depends on factors such as climate, foot traffic, and the age of your surfaces. If you notice that water no longer beads up on the surface or the color is fading, it’s time to reseal.

By properly sealing your flagstone and interlocking surfaces, you can ensure that they stay beautiful, protected, and safe for years to come.

Repairing Cracks and Damages

As much as we try to maintain our flagstone and interlocking surfaces, cracks and damages can still happen. It’s essential to repair them as quickly as possible to avoid further deterioration and ensure the safety of your family and guests.

Cracks: For small cracks, you can use a commercial crack filler or a mixture of Portland cement and sand. Fill the crack and let it dry, then scrape off any excess filler.

For larger cracks or missing pieces, it’s best to replace the damaged stones. Remove the damaged stone and prepare the base by removing any loose material and leveling it. Place a new stone and fill the gaps with sand, then use a tamper to ensure that the stone is level and secure.

Other damages: If you notice any loose or wobbling interlocking pavers, remove them and clean the area. Apply a layer of sand and reposition the paver, tapping it gently with a rubber mallet to ensure it’s in place.

If you’re unsure about how to repair cracks or damages, or if the damage is severe, it’s best to contact a professional. They have the expertise and tools to handle any repair job effectively and efficiently.

Preventing Weed Growth

Weeds can be a pesky problem on your flagstone and interlocking surfaces, detracting from their beauty and posing a tripping hazard. However, preventing weed growth is easier than you might think.

Effective Weed Control Techniques

One of the most effective ways to prevent weed growth is to keep your surfaces clean and clear of debris. Regular sweeping or using a leaf blower can help to remove leaves, twigs, and other organic matter that can attract weed seeds.

You can also use natural weed control methods, such as pouring boiling water or vinegar on weeds, or applying salt or cornmeal to the cracks and crevices. However, be careful not to use harsh chemicals or other substances that can damage your surfaces.

Using Weed Barriers

Another way to prevent weed growth is to use weed barriers, such as landscape fabric or plastic sheeting, underneath your flagstone or interlocking surfaces. These barriers can block the growth of weeds while still allowing water to drain through to prevent water damage.

When using a weed barrier, ensure that you install it properly, covering the entire area and overlapping the edges to prevent any gaps. You can also use a layer of sand or gravel on top of the barrier to further prevent weed growth.


Preventing weed growth on your flagstone and interlocking surfaces is an essential part of their maintenance. By keeping your surfaces clean, using natural weed control methods, and using weed barriers, you can minimize the time and effort required for maintenance and keep your outdoor spaces looking their best.

Winter Maintenance for Flagstone and Interlocking Surfaces

Winter can be a challenging season for maintaining your flagstone and interlocking surfaces. The cold temperatures, snow, and ice can cause damage and create safety hazards. However, with the right approach, you can keep your surfaces safe and in good condition throughout the winter months.

Preparing for Winter

Before the first snowfall, it’s essential to prepare your flagstone and interlocking surfaces for winter. Start by cleaning the surfaces thoroughly to remove any debris or dirt that could get trapped under the snow. This will prevent staining and damage from freezing and thawing cycles. You can use a broom, leaf blower, or pressure washer to get rid of any debris.

It’s also recommended to seal your surfaces before winter to provide an extra layer of protection against moisture and salt. A quality sealer can prevent water from penetrating the surface, which can cause cracks and other damages. Be sure to choose a sealer that is suitable for your specific surface material.

Snow and Ice Removal

Snow and ice buildup can create safety hazards on your flagstone and interlocking surfaces. It’s important to remove snow and ice promptly to prevent slips and falls. However, it’s crucial to remove the snow and ice correctly to avoid damaging the surfaces.

It’s best to use a plastic shovel or a snow blower with rubber blades to remove snow from the surfaces. Avoid using metal shovels or anything with sharp edges, as they can scratch or chip the surface. Also, be careful not to use too much force when shoveling or blowing snow, as it can loosen the interlocking pavers or crack the flagstone.

If there’s ice buildup on the surfaces, avoid using rock salt or other ice melting products, as they can damage the surfaces over time. Instead, use sand or kitty litter to create traction and melt the ice naturally.

Preventing Ice Buildup

One of the best ways to prevent ice buildup on your flagstone and interlocking surfaces is to keep them free of snow. Regular snow removal can prevent snow from melting and refreezing, which can create dangerous ice patches. Additionally, keeping your surfaces clean and dry can prevent water from getting trapped and creating ice.

You can also use a snow melting system, which is installed underneath the surface and melts the snow as it falls. While this option can be costly, it can be an effective way to keep your surfaces safe and free of snow and ice during the winter.
