What Our Clients Say
Fantastic experience from start to finish. Mario and his crew explained everything clearly, gave us a fair price, and finished the work earlier than expected. Our front steps look better than when the house was first built.
Nice to work with a company with excellent communication, competitive pricing and that delivers on time. A rarity these days. Mario and his guys did a great job on our chimney. Showed up early for work and got the job done. Would absolutely recommend Automatic Masonry!
Automatic Masonry did an amazing job! From the moment they came out to provide a quote to the completion of the repair, the entire process was within a week. They were quick, professional, and extremely knowledgeable. I’m very pleased with the quality of their work and highly recommend them!
We regularly hire Mario for assistance on jobs. He’s punctual, respectful and organized. Would recommend him to anyone looking to have work done.
Mario and his team were great to work with. Very knowledgeable and explained the work being done in advance. Thank you!
Awesome experience working w Mario. He replaced two stone steps on my front porch that were cracked and causing lots of issues. His quote was fair compared to others, was precisely on time, work got done fast, the work got done right, and he cleaned up afterwards (so rare!). Looking forward to working with him again.
It was good to meet Mario. Communication is very clear. He explained all the work and was honest on options and cost. He did what he said he was going to do in the time that he said was going to do it.
I’ve used Automatic for multiple masonry jobs in commercial buildings. They provide excellent work and projects are completed on schedule.
Mario did an excellent job on my walkway. He was very responsive in the planning, very upfront with the pricing and the job was done exactly as described. Highly recommend Mario!

Flagstone Masonry FAQ
Flagstone Masonry FAQ
Still have questions?
Can’t find the answer you’re looking for?
Feel free to reach out — we’re happy to help.
How long does a typical flagstone project take?
The timeline depends on the scope and complexity of your project. Small walkways or step installations may take 1–2 days, while larger patios, driveways, or custom features can take up to a week or more. Our team provides a clear schedule and keeps you updated throughout the process.
Can you match existing stone and mortar?
Yes! We carefully select natural flagstone and custom-mix mortar to match existing colors, textures, and patterns, ensuring seamless blending with your current surfaces. This is especially important for repairs or extensions to existing patios, walkways, or steps.
Can flagstone be installed over concrete or uneven bases?
Absolutely. Our team can lay flagstone directly over concrete, asphalt, or uneven ground by preparing the surface with proper leveling, drainage solutions, and professional adhesive or mortar techniques to ensure a durable and long-lasting finish.
How do you protect flagstone from water and freeze-thaw cycles?
We use high-quality mortar, proper joint filling, and drainage solutions to prevent water infiltration. In some cases, a breathable sealant is applied to protect the stone without trapping moisture. These steps help flagstone withstand Toronto’s harsh winters and wet summers while minimizing cracking or shifting.
How much does flagstone installation or repair cost?
Costs vary depending on project size, stone type, and complexity. Smaller repairs are more affordable, while full patios, driveways, or custom designs require a detailed estimate. Contact us for a free, no-obligation quote, and we’ll provide transparent pricing tailored to your project.
