Flagstone Design & Installation Services in Toronto

Flagstone, also known as natural stone, is so popular because of its natural shape and colour, offering a range of configurations and designs based on the stone itself. It is used to create beautiful patios, walkways, pool coping, porches, and so much more! By utilizing the stone’s natural form, you can create unique designs that can never be able to be repeated elsewhere.

Our team of specialist landscape designers and flagstone contractors will work with you to select the type of stone, flagstone design and configurations for your home. Together, we can create stunning pieces of stonework that are so much more than just a ‘walkway’; it is a piece of art.

Different Types of Flagstone That We Repair

There are many different shapes and colours of flagstone. However, the most popular types are random or calibrated flagstone. Each of these flagstone types has its own benefits. For instance, random flagstone is relatively cheap, and it is sold by weight. Also, it has a variety of different colours which you will not find from other companies.  The interesting fact about random flagstone is that it is almost impossible to find two stones of the same colour.

On the other hand, calibrated stones are easier to install and have square or rectangular shapes. Creating a more uniform design that our designers will have a lot more control over. Both of these types of flagstones look great, so every homeowner has to choose which one suits them best.

Why Are Flagstone Porches So Popular?

The narrow pack joints of flagstone make it a superior option when it comes to building materials for porches. Instead of water running off the porch, the narrow packed joints allow it to permeate. Flagstone is also incredibly durable, and it can be laid dry for a permeable surface. The permeable surface allows grass, moss and ground to be grown between the stones of the porch, making it great for outdoor surfaces.

Aside from all of the other benefits, flagstone porches have a very natural look because of their shape and earthy shades. The most common types of flagstone used for porches are sandstone, slate and limestone. Flagstone porches are durable, naturally slip-resistant and will last you for years to come.

Our Professional Flagstone Repair Process

When flagstones become loose, cracked, or uneven, the problem is often linked to a weak foundation below, improper mortar installation, or failed bonding between the stone and the setting bed. If these issues are not corrected properly, the flagstone can continue to crack, shift, or separate over time.

At Action Home Services, we focus on precision installation and repair techniques that help restore both the appearance and long-term durability of your flagstone surfaces. Here are the steps we follow to ensure proper flagstone repairs.

Step 1: Thorough Inspection

The first step is to assess the surface damage and lift the existing flagstone carefully without causing unnecessary damage to the surrounding area. This allows our team to fully expose the surface below and inspect the condition of the base, mortar, and stone placement. Note that we aim to preserve reusable stones for reinstallation.

Step 2: Inspecting the Base

Once we remove the flagstone, we inspect the base to determine whether it is still stable enough to support the flagstone. A weak or improperly prepared foundation is one of the main reasons flagstone surfaces begin to crack, shift, or sink. If the base is failing, we rebuild it before installing the flagstone. This gives the repaired surface a stronger, longer-lasting foundation.

Step 3: Removing Old Mortar

All old mortar must be removed completely from the stone and the installation surface. Leaving behind weakened or loose mortar can affect bonding and reduce the strength of the new repair. A clean surface is essential for proper bonding and for achieving a more secure finish.

Step 4: Apply Concrete Bonding Adhesive

After the surface is properly cleaned and prepared, a concrete bonding adhesive is applied where needed to improve adhesion between the old surface and the new mortar bed. This is important because proper bonding plays a major role in the long-term durability of flagstone repairs. Without strong adhesion, the stone may loosen again.

Step 5: Install a New Professionally Mixed Mortar Bed

Once the bonding layer is ready, we install a new professionally mixed mortar bed. The quality of the mortar mix matters. Improper mortar is one of the leading causes of joint failure and loose flagstone. At AHS, we ensure the right mortar mixture to provide the support, strength, and bonding needed to keep the flagstones stable over time.

Step 6: Reinstall the Stone with Precision

Now that the new mortar bed is placed, the flagstone can be reinstalled carefully and aligned for a secure, even, and visually consistent finish. This requires precision because flagstone pieces often vary in shape, size, and thickness. Proper placement helps improve stability, maintain the intended layout, and reduce the risk of future shifting.

Why Do Flagstone Joints Crack?

There are two main reasons why your flagstone joints are failing:

Low-quality cement or mortar was used: There is a very specific ratio of cement and sand that should be used to create your mixture. Instead of attempting to recreate the formula, we recommend purchasing premixed mortar. If only cement is used, the cement will crack, and the repair job will not last long.

If only sand is used, the joints will never harden. This is because sand absorbs water and holds moisture; when colder temperatures cause freezing, it can expand up to 9 percent, which will result in the mortar cracking.

The bottom surface (under the flagstone) was not done correctly: If the gravel base moves, it will cause the joints to crack. To check the base, you will require professional technicians to lift the flagstones.
