Precision, Passion, and Personalized Landscaping

Landscaping projects don’t always turn out the way homeowners expect. Too often, designs get compromised, corners are cut, and subcontractors rush through the details, leading to delays and disappointing results. You shouldn’t have to settle for a project that falls short of your vision.

At Kasty Landscape Group, every project is completed in-house, ensuring reliable scheduling and strict quality control. With no subcontractors, work stays on track, and every detail meets the highest standards. From construction to aesthetics, nothing is overlooked—your outdoor space is built to last, with thoughtful craftsmanship that fits seamlessly into your lifestyle.

“The entire process was efficient, professional, and best of all, stress-free.”

“A big thank you to Alex from Kasty Landscaping (and his awesome crew, Karman and Shane!) for our beautiful new patio. The entire process, from the initial design that Alex drew for us to the fabulous finished patio, was efficient, professional, and best of all stress-free. Both Paul and I were amazed at the attention to detail and obvious care that Alex and the crew put into their work. We have had endless comments and praise from our neighbours, family, and friends. We love our new backyard and can’t wait to have the crew back next year for another project.”
