Reviews

What customers say

Customers praise respectful, hardworking crews. One customer singled out complicated paver cuts and a seamless finish. A neighbour reported that a fence installation next door left piles of post-hole dirt and that most post-hole concrete was poured on their property; they described the contractor as arrogant and condescending.

Customer Reviews

Lawrence In

After our kids left for college, we decided to redo our water-hungry, high-maintenance backyard. A friend recommended Permagreen Landscaping, and working with Kaster was a breath of fresh air. He listened, didn’t push extras, and brought creative, thoughtful solutions—especially when it came to a tricky gas heater install near our pergolas. What started as a simple paver job became a full transformation: demo, grading, new planters, drainage, pavers, artificial turf, native plants, trees, and lighting. His crew was respectful, hardworking, and cleaned up beautifully. This wasn’t just a job—it felt like a partnership. Kaster was honest, experienced, and stayed on track despite bad weather and outages. Highly recommend Permagreen for anyone serious about quality landscaping.

No respect for Neighbor's property! They put up a fence for the property next to me and left piles of dirt from post holes dug. They poured the majority of the concrete for these post holes on my property. They knew before hand that I will be putting a retaining wall on my side of the property line as well as a fence. This contractor was arrogant and condescending about this matter and knew perfectly well of my plans as he even provided an estimate to do my project. As always with contractors check their license and possession of proof of Workers Compensation Insurance for their workers, unless you have a premium home owners insurance policy, which most people cannot afford. 2/14/2025 I reviewed your reply, if this is how you respect surrounding areas, I.E. neighbor's property and lasting attitude against them then I see no reason to change my review. My project will take place but in my own time. If you were serious about your effort to remedy your errors you would provide a notorized statement as such interested of updating and further disrespecting the issue.

Showing before and after photos. Kaster and his crew were great to work with. He was very responsive and made sure the project got done per the parameters of the agreement. I was doing the lawn to garden conversion and wanted to get the least expensive option to qualify for the rebate. He gave me a very reasonable price and did an amazing job. And I was able to get the rebate approved! I 100% recommend Kaster and Permagreen for any landscaping work.
