Flagstone Design & Installation
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 is so much more than just a ‘walkway’, it is a piece of art.

Different Types Of Flagstone Available
There are a lot of 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 the environment.
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.
How We Install Flagstone & Natural Stone Steps
Step 1: First, we will measure and level the area. This includes measuring the area for the step’s width and depth, as well as making sure that it is level with the ground surface.
Step 2: When the area is levelled, we will lay down a base layer of gravel before installing your natural stone steps. This is important because it will provide an even surface for your stones to rest on and will help keep them from shifting over time.
Step 3: Now that we have a stable base layer ready, it’s time to start placing down the natural stones! We will lay out the stones so that they are evenly spaced apart from one another and will begin securing them in place with mortar or concrete adhesive.

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.

Professional Flagstone Repair Services
Over time, flagstone can become loose, from the mortar to the stones themselves, and flagstone can start to degrade after years of use. To repair flagstone, you would typically want to use the “wet method,” which uses cement. Whether you have a flagstone porch, steps, walkway, or interlocking paver driveway that needs repair, we encourage you to follow these steps to guide you through your repair:
Step 1: Lift the flagstones and clean the area.
Step 2: Mix mortar with water. Install mortar on the ground surface and on the back of the stones.
Step 3: Install the stones back in place and wait a couple of hours for the stones to harden into place.
Step 4: Fill the ground/cracks.
Step 5: Use a sponge or brush to clean the surface of cement residue and rinse of the area.
Step 6: Enjoy your new flagstones!
