"I found Green Mountain Outdoor Living on the web and I’m so glad I did!! Peter is a really, really wonderful guy and was very fun to work with. He’s got great ideas and really helped me figure out what started out as pretty vague ideas in my head. We got rid of a bunch of lawn and replaced it with great flower beds and a little stone walkway. Peter’s bid was entirely reasonable and the whole job was executed perfectly! The crew was just great, each guy was hard working, fun, respectful, attentive to detail - I can’t say enough good things about them. Each of them clearly took pride in his work. Shout out to Cole, who stayed late at least two evenings (including one in a thunderstorm), just getting everything right. I love these guys and look forward to working with them again next year on other parts of the yard!"

They made sure every detail was exactly to my liking along the way, and the quality of their work is outstanding.

"Green Mountain Outdoor Living (GMOL) did a great job on my back yard. My yard was in really rough shape after I had removed a very large wooden deck which took up a huge area. The removal exposed the rubble from the original house construction after the 40+ years it had been in place. The rest of the yard was bare earth from past years of draught and dogs. Also, I had a huge amount of unsightly field stones everywhere. GMOL was not the first company I had contacted, but they were the *first* to be responsive to me. Peter answered my call right away and was super quick to come over to walk it down. After truly listening to what I needed, we mutually came up with a plan within my time and budget requirements. His team was scheduled within a week. The very respectful team moved all the loose rocks, using them to build a natural-looking berm that I needed, which turned out looking better than what I had even hoped for! They cleaned up the old debris, then laid down soft, natural mulch for my dogs, and added stones at my house foundation for both aesthetics and better fire mitigation. They also spruced-up my front yard so it is looking fresh! My dogs are ecstatic! They loved chasing each other up and down the fresh ground cover! The photo below is not showing the full extent, but it does show happy huskies! :-)"

"Green Mountain Boys built our hardscape patio and the whole experience felt sharp from day one. The design process was collaborative and thoughtful — they walked the space with us, offered strong ideas on layout and materials, and made us feel confident without ever being pushy. The crew works hard and takes real pride in their craft. The patio base is rock solid, the cuts are clean, and the finished space feels intentional and high-end. Great attitude, great communication, and a result we’re genuinely proud to show off."

"We had a great experience with Green Mountain Boys. Peter came out, walked the property with us, and actually listened. He asked how we use the yard, what we cared about, and where we wanted to invest versus save. He offered suggestions and we were impressed with his plant knowledge and creative ideas. The design process was simple and clear. No pressure, no upselling — just honest conversations and solid ideas. Once the job started, the crew showed up when they said they would and kept the site clean. The finished product looks sharp and feels built the right way. You can tell they care about doing it right, not just getting it done."
