Flagstone works by Alterra

Using natural stone is like adding a touch of nature to your outdoor space. It is the heart and soul of outdoor design because it blends so well with other materials.  At Alterra, we use natural stone for all sorts of things like paths, pool decorations, BBQ areas, and more. There are different types of natural stone like sandstone, limestone, granite, and quartz, each with its own unique structure and style. This affects how they handle things like frost and water. Take limestone, for example. It’s not just easy on the eyes; it can stay looking great for about 25 years! Plus, it’s not as pricey. But if you want something super long-lasting, go for granite flagstones

Happy Clients of Alterra Landscaping

Alex was in constant communication with us and started when he said he would. Alex did all the stone work and was fantastic. You can tell he loves his craft. They removed the old material and did the joints. It was tough to remove. Extremely hard working crew and did everything they could to complete the job with quality and speed. It took 5 days in total but was worth it. Courteous and clean.
Homestars Review
These guys did an outstanding job installing a flagstone walkway around our house. Alex was very careful to install and make sure that the work would be as weatherproof as possible given our Canadian winters. Would recommend them to anyone. Would use them again .... Clearly.

Frequently asked questions

How is a flagstone installed?

We excavate the soil, add hard rock and screening, form and pave concrete, and finally install flagstone with cement underneath for a secure, durable finish.

What types of flagstone are available, and how do they differ?

We offer random flagstone, known for its variety in color and cost-effectiveness, and calibrated flagstones with uniform shapes, making installation easier. Choose based on your preferences and needs.

How are gaps between flagstones handled in the installation process?
To ensure stability, we fill gaps with cement or polymeric sand, providing a secure and visually appealing finish to your flagstone walkway or patio.
