Landscaping reviews in Denver, Colorado

Angie provided a wonderful plan and made good suggestions on plant types to suit the space and existing configuration and other plants in our backyard. We replaced a large area of grass. Rafa, Alex and crew did a good job on installation. The result was a cosy and calm place which I look forward to enjoying in years to come.

Rafael and his team did an outstanding job in preparation for our deck by re-grading an area, installing block edging and pruning shrubs. Job was done quickly and looks great!

Rafael and team were quick, efficient and helpful when it came to planning an unexpected landscaping project. They helped us imagine a great design and use of space and went above and beyond to create the perfect zen part of our yard.

I have been doing business with Guaranteed Excellence for almost 30 years. They have built retaining walls, updated the sprinkler system, planted gardens, trimmed trees, removed trees, mulched and rocked. You can trust them to be knowledgeable, to show up on time, to do a beautiful job, and to leave the job site meticulously clean. Good guys!

After a few back and forths with the designer we finally locked in on a plan. Marco and his crew showed up and completed the job with success. The crew was large, the complicated job was done within a day. Cleared tons of weeds, created a path, demo’d previous pavers, and added beautiful, paver patio. Marco, the crew lead, was very helpful and extremely nice.

I recommend hiring this company for your next landscaping job.

Rafael and his team were great! He came out immediately when I called for an estimate and fit me in quickly. The guys didn't waste a minute and flawlessly removed my big, dying elm tree, pulled down broken branches from my giant maple and cleaned up perfectly. Nothing gets in the way of them accomplishing a task. I will be calling GE back again to do a lighting project.

They provided excellent service at a reasonable price. Absolute quality work. I have had them do a retaining wall in my front yard with landscaping (in the past). I have had them remove grass and prepare soil in large areas for me to do my own landscaping (in the past). Most recent was them replacing my broken down brick steps in my back area with new, beautiful, wide, safe steps. I highly recommend them!

We originally had some hiccups, but after voicing my concerns, this team listened. Angie listened and was patient as my husband and I worked with her to find the perfect iteration of our design. Alex was very professional, and his team worked quickly and efficiently to deliver a very professional final product. We love our new xeriscaped front yard, and are looking forward to working with Angie again in the spring to add some plants!

They made my house feels like a home ✨ I had the best experience ever! Very thoughtful and professional. Marco, Rafael, Angie and Jerome are all amazing to work with! I highly recommend!

Its a great landscaping company. I will surely recommend them.
I came to know about this company when Junior was visiting door to door in our neighborhood. He was professional and helped in setting up our first appointment with Angie.
She was brilliant in her work with design ideas and was patient in responding to all our queries. She even offered us to visit some of their existing customers to get feedback. This was very positive experience to hear from others too.
We loved their design ideas and Rafael & Angie were great to talk through the entire design process and pricing was good too.
When it came to actual work, they scheduled very well and Marco & team delivered a great quality to us.
Overall Rafael & team are very good in their work. Their service after the work completion is good for any corrections or plant replacements.
Thank you for your services.

We used Guarantee Excellence landscape about 10 years ago for our backyard and they did excellent job back then. There were many times I wish I could recall their contact information for our landscape needs because other landscapers we used didn’t measure up to their performance. However, out of the blue we received one of their mailers and we hired them to regrade our front lawn, install a retaining wall, replace and reseed the lawn with lower water required seeds and install water efficient sprinkler heads. They did a great job at a very reasonable price and will use them again in the future.

Update- low growth seeds did come up very nicely in the front lawn. We ended up hiring them again for more work in the backyard. They did excellent work filling the pond/foundation and converted into a paver patio and another patio across from it. We also had them build us a sunset viewing deck with 30 steps leading up to it. We are so very happy with their work and would strongly recommend them for any landscaping projects.

Rafa and his team did a great job with our backyard. The before and after photos are night and day. The guys worked hard to get the job done quickly and the results are beautiful. Would recommend!

I can’t even begin to share how pleased we are after using Guaranteed excellence to give us the back yard of our dreams. We recently purchased a home that had a backyard that consisted of dirt, weeds, and garbage. My husband and I decided we needed to have a professional handle the job. Angie was our first point of contact that assisted us with the design and gave us a very fair quote (8000$ less than their competitor for the exact same thing). We had all of the weeds and rubbish removed, added irrigation, rock edging, trees, added a sitting area, drip lines for raised beds, paver walk ways, and sod. (I will add my dad owned a sod farm/landscaping company for 30 years so I am well aware GE went above and beyond in the process and did everything to the book and the best way possible for the best results).
GE completed the project in just 3 days. Alex was the lead guy on the job and he was wonderful to work with, checked in a lot to ensure we were happy with how it was going. The crew showed up early every single day and worked SOOOOO incredibly hard, it would have taken all summer for my husband and I to do the job ourselves and probably wouldn’t have turned out half as good. We couldn’t be more happy/giddy and will be looking to hire them again in the future to tackle the front of our house. Money well spent and we can’t wait to enjoy our new space!! The before and afters speak for themselves. Don’t think twice about hiring them.

**Updated - added 2 photos from the end of the summer (8/20). Worked with Angie (designer), Alex (landscaping) to design our new-build backyard at Lyric in Lone Tree. Angie made excellent reccommendations on plants, trees and design options that fit what I wanted and helped curate the docs I needed to submit for HOA approval. The installation team is professional, detail-oriented and went above and beyond on a couple asks that came up during the install process. GE was competitively priced and I would use them again in the future. Lived up to the name!

Guaranteed Excellence transformed our front yard from dated and disjointed to a beautiful modern show piece. Rafael and his team were great from start to finish. The communication was excellent in terms of expectations and pricing. The installation itself took a little over a week and the attention to detail was amazing to watch. Each person took pride in their work and ensured throughout the process that we were getting exactly what we wanted. We couldn't be happier with the final result which exceeded our expectations. We would highly recommend Guaranteed Excellence!

We had Tran install a patio extension, walkway, and some plants to our house and it turned out amazing. They worked very quickly and charged much less than some of the other quotes we received. We would highly recommend them.

Timely professional service.

Great work. Reliable.
