1. Three Seasons Landscapes
4.5 (17 reviews)score 76/100
Three Seasons pulls the highest composite score in this group on the strength of a near-perfect sentiment record across both residential and commercial jobs. Reviewers repeatedly name individual staff, Nicole, Matt, Chris and Sierra, for detail-oriented work and quick responsiveness, and the firm carries projects from permits through final install.
- Named crew consistently praised (Chris, Nicole, Matt, Sierra)
- Handles full projects from permitting to completion
- Fast aftercare, including a paver reset within two weeks of a client email
- Transforms properties rather than just executing a spec
Watch out: One review flagged inconsiderate parking on narrow Glanbrook streets during a job.
Services: landscape design installation, lawn care maintenance, eco friendly organic, tree services
2. Meg & Kennedy Landscape Design Inc
5 (9 reviews)score 73/100
Every review on file for Meg & Kennedy is five stars, with clients repeatedly crediting Meaghan for translating a vague idea into a workable plan and backing it up with 3D renderings before anyone breaks ground. The firm takes on layered projects like pool integration and multi-season plantings, though the review count is still small enough to treat as an early but consistent signal.
- 3D renderings shown before construction starts
- Deep plant knowledge tuned to seasonal durability
Services: landscape design installation, lawn care maintenance, licensed insured
3. Kastrau Landscaping & Nurseries Ltd
4.5 (37 reviews)score 76/100
Kastrau has the most review volume of any specialist here, and Peter's hands-on involvement, personally selecting and planting trees, backed by a one-year warranty, keeps coming up as the reason clients stick with them. The draw is access to large specimen trees that competitors don't stock, alongside broader hardscaping work.
- Owner personally selects and plants trees
- One-year warranty on tree planting
- Specimen trees not available through other Hamilton suppliers
- Crews arrive on time and leave a clean site
Watch out: A few reviewers said pricing on the largest specimen trees runs high.
Services: hardscaping interlocking, landscape design installation, lawn care maintenance, tree services
4. Hamilton Sod
5 (2 reviews)score 60/100
Hamilton Sod's two reviews both describe clean, efficient installs with useful aftercare guidance on keeping new sod healthy. That's a thin sample spanning several years, so treat this as a lower-confidence pick worth confirming directly before booking.
- Professional, efficient crew on install day
- Reliable, on-time delivery
Watch out: Only two reviews on record, so the track record is hard to verify at scale.
Services: landscape design installation, lawn care maintenance, irrigation lighting
5. CR Landscape
4.6 (11 reviews)score 61/100
CR Landscape benefits from Marco's direct involvement in design, quoting and follow-up, and reviewers point to punctual, high-standard work backed by decades in the trade. An older complaint about slow response times shows up in the record, but more recent feedback describes consistent communication.
- Marco personally manages projects start to finish
- 40-plus years of operating experience
- Same-day or next-day scheduling available
- Design expertise tailored to individual yards
Watch out: An older review cited slow response to inquiries, though recent feedback reads more consistent.
Services: hardscaping interlocking, landscape design installation, lawn care maintenance, eco friendly organic
6. Design Jam Permaculture
5 (1 reviews)score 55/100
Design Jam Permaculture is a niche pick for anyone wanting Adrian's systems-based approach to ecological design and the mentorship that comes with it. The available feedback is limited to a single five-star review from several years back, so this is one to vet with a direct conversation before committing.
- Focus on permaculture and ecological gardening principles
- Mentorship in design philosophy, not just installation
Watch out: Only one review on file, and it's several years old, so recent service quality isn't well documented.
Services: landscape design installation, lawn care maintenance
