Very responsive, delivered great looking trees at a fair price. Will be using them again in the future.

Outstanding work from Nick and his team. Provided excellent guidance to meet our needs and was exceptionally responsive when we asked questions. Will definitely be using them going forward.

Came out and knew exactly what to do at a new place. Provided useful information for the spring. I'm going back to non DIY.

Extremely satisfying working with Nicholas and this company, and this is all before the work even began. Nicholas was extremely responsive, came over for initial review and measurements, and was very open to all input on the plans (which is something I notice is NOT the norm with all companies). I was surprised at how responsive and quickly they started, not actually expecting the timeliness considering I was sure they had other customers in work. Patio pavers, landscaping redesign, and a fire pit all done incredibly beautifully, and amazingly color coordinated to match my back deck. They responded to every single query, regardless of how minor, within a day. Again, from my personal experience, this just doesn't happen in Southern Maryland. I've already got future plans swirling on a possible project based on this outstanding job.

Jim and his crew installed water up at our shed and irrigation system in out new garden area. They were just great! Surveyed the job and what had to be done and got to work and did a wonderful job. Very neat, hard working, friendly, polite, & eager to please. Great clean up! Highly recommend!

Nicholas and his crew did a phenomenal job on our paver patio and landscaping. Nick was a pleasure to work with from the design phase all the way through the final payment. Completely professional and patient with numerous changes on our end. His crew was fast and effective and the job ended up being absolutely amazing! The overall cost was extremely competitive with other estimates I received and Nick was super responsive from the estimate to job completion. If you want affordable and beautiful work done by a team of professionals who actually return calls and emails, take my word, and look no further than Collentro!

First I want to thank Nicholas for being so responsive to my questions and emails and not getting irritated at my lack of knowledge in landscaping! They did an amazing job, it was not a normal porch design.
They did the whole job back to back in 3~4 days and did an amazing job cleaning after themselves as well and re-seeding the grass that was crushed. I was worried in the beginning from past experiences of hiring people to do this type of work and was asking Nicholas a lot of questions, and he literally answered every single one of my question within 10 minutes of me sending an email.
I also had deck staining done from them as well, with few missed spots, I emailed Nicholas and he responded immediately saying his carpenters will take care of the missing spots, and gave me the left over stain for me to continuously maintain the deck.
I would highly recommend them!

I absolutely can not say enough about these guys. From the start, Nick said we will get this done right. John and his crew were incredibly professional and thorough. Their attention to detail is impeccable. Thank you again from turning a bad experience because of another contractor into a great deal of joy for our family.

Collentro did an amazing job at building our patio. All aspects from the beginning stages of designing with Nick to the team who built it and our modifications along the way, all went smoothly. We couldn’t be happier and look forward to contracting with them for future projects.

We are extremely satisfied with our new 660 SF hot tub patio. In about 4 days the team had excavated, rerouted drainage, installed a conduit for the hot tub wiring, installed the patio (including 2 matching steps), and regraded/seeded the area leading away from the house. They were patient with our questions before and after installation. We will have them back.

Nick,John and Vallerie all were awesome to work with. We got several estimates for our new patio and firepit including seating wall. Nick’s personality was huge in selecting his company for such a huge important project for us. Price was fantastic and our end product was more than what we paid for. My husband and I particularly noticed their extreme attention to detail. Making sure each and every stone was cut perfectly and set level. Every night they cleaned up their work zone. They were very patient with my husbands many questions. And as I stated earlier the end product was Amazing! We will have many fun gatherings on our new beautiful patio/fire pit. I will recommend him to all my family and friends.

Extremely satisfied with the new trees and hardscape around our pool!!! Nicholas and his crew are personable and easy to work with. Highly recommend Collentro Landscaping for any landscaping needs.

Nick, Jim and the Collentro crew (including Valerie in the office) were wonderful to work with! They were pleasant, polite, extremely responsive and patient with questions.

It is obvious when working with them that producing a beautiful quality result is important to them.

My front planting beds got cleaned up and were given a new look. Irrigation was installed for the yard, and in the backyard, new retaining walls and beautiful patio were built, grading and new sod put down.

The backyard now makes me want to spend time outside.

I would definitely recommend them and would work with them again.

We are thrilled with Nick and his crew's work. They installed French drain, graded, and installed pavers on walk. Great work !!!

Jim from Collentro Landscaping did a phenomenal job with my irrigation install. He was meticulous, he didn't tear up my yard, was very patient with all my questions, and the system is working like a charm!!

Easy to deal with and they do great work. I don't ever write reviews, but felt Collentro deserved one. Great Job!

I had a retaining wall put up on the top of a hill the entire length of my property. The work and materials used were of the highest quality as was the professionalism of the crew. Mr. Collentro was on-sight every day working with his crew. The job was completed on time and exceeded my expectations in all aspects, including cost. I recommend them to anyone in need of a job well done.

The crew from Collentro Landscaping and Design designed and built a terraced wall to protect an eroding bank. They did a professional job, using good materials, and taking care of all the little details. Not only does it look great but we added another project to their list while they were here. We would recommend them to friends and family.

Collentro's did a project to save a hill side damaged rain fall. the job turned out great, they were very professional , I would recommend them to anyone needing that sort of work

Fantastic company to have for your landscaping needs.

Collentro Landscaping went above our expectations. I could not recommend them enough.

Collentro just recently installed my irrigation system, and it's great!

I had seven zones installed (front and backyard) and have some challenging slopes (hills) in the front and backyard. Jim and his crew arrived at the house first thing in the morning and worked literally till sundown, completing the install!

Jim was my last estimate out of three. I had pretty much made my mind up with the previous estimate (2nd) I'd received, but thought "what the hell, I'll hear what he has to say!". After talking with Jim and reading the reviews about Collentro, I called an audible and went with Collentro.

Jim has been responsive to text messages, helping me tweak changes with the WiFi controller app.

The irrigation system was the last project in a five year plan with our front and backyard landscaping. We are extremely happy that the last project ended with a positive outcome.

I would recommend Collentro Landscape and Design to anyone looking for an Irrigation system and more!

These guys are amazing! I had a big project of regrading, drainage and clearing to do and was looking for someone who could help me with my issues. I stumbled upon Collentro and so glad I did. Nick came out and answered all my questions while giving great insight on how to solve my drainage problems with water going back into my foundation. I felt confident moving forward with them and in no time he was out clearing stumps, extending underground downspouts and regraded the yard. He and his team are very professional, and bless his patience for my many questions I had pop up during the project. On top of that, all clean up was managed and the yard looks wonderful! If you are looking for someone for drainage or anything landscape related choose Collentro!

Great service and friendly! We had irrigation installed and are very pleased. Definitely Recommend these guys for irrigation needs.

Extremely pleased with my experience working with Nick and his professional team. I enlisted their services to install an irrigation system and perform some lawn rejuvenation work at my residence. Even during a tough and uncertain time with the COVID pandemic, the full work crew arrived on schedule, performed excellent work, and for a fair price. I will definitely contact Collentro for future landscape project at my home in the future.

Nick and his crew were professional and knowledgeable while being very personable. I highly recommend Collentro Landscaping for all your yard needs/wants.

We contacted Collentro after we built out home for landscaping the front due to time limits with the HOA rules. Nick gave us a quote that beat the others. He did such a great job we had them plant our yard, do our fire pit and install pavers in the back for a patio. Next up is lighting. Anything that’s been not right per his perspective he comes back out to fix at no charge to us. We also had deadlines due to a family wedding and he went above and beyond to meet our deadline. Great quality and very personable. Always available to answer questions and give suggestions. Give them a chance. You won’t regret it!!!

I started using Collentro Landscaping last summer for occasional mowing to help my husband out. They do a very thorough job with the mowing, trimming and clean-up. We were very happy with their work. Earlier this year I had a tanker truck back up into a brick monument we have at the end of our driveway and completely knock it down. Nick happen to see it when he was over to plow our driveway after a snow storm and gave us an estimate. Nick and his crew just finished repairing the monument and it looks great. They were able to do the job in one day and unfortunately for them it rained the last half of the day. Nick and his crew are very hard workers and take pride in the work they do. If you need anything done in or around your yard this is the company you want to hire.

Nick and his team did a spectacular job creating beauty from an overgrown mess and and eyesore. If you have any landscape or design work please contact these guys. It will be the best decision you will ever make.

Nick and his crew did on outstanding job of cleaning and mulching my garden which is quite large. They arrived on time worked tirelessly the entire day and cleaned up behind themselves. I will definitely call on them again.

Collentro Landscaping was prompt, friendly, and offered a fair price to winterize my sprinkler system. I highly recommend them and will definitely call them again.

We were on an extremely tight deadline. We just built the house and nothing was done in the yard. We had a wedding for daughter and guests were staying with us. We wanted it done prior and they did just. We had a sprinkler system, flower beds, drainage, and over seeding extremely large yard. They worked long hours and weekends to get it done. Turned out beautifully!! Highly recommended.

We built a house and needed to get the yard done. We had a wedding coming up and wanted the yard done prior since people were staying us. They work long house and tough schedule but they finished it in time. I feel they went above and beyond to get it done. We had flower beds, sprinkler system and lawn seeding. Well worth it!!! Don’t pass them buy.

I had fallen very (VERY) behind on the maintenance of a large double-lot property with a lot of landscaping and a great deal of things to be done. In a day and a half these folks had my place restored and beautiful. I wish I had before and after pictures to display - the property looks amazing, completely different. The amount of work required was huge, and Collentro did it fast and at very, very fair rates especially for the quality they provided against the workload that was necessary. I will be retaining them for regular service. The professionalism and attention to detail is stellar. I absolutely recommend them to anyone needing any of the services Collentro provides.

My wife and i hired Collentro Landscaping to come out and transplant some plants and trees for us. We were installing a small detached garage and did not want to lose some of our more established plantings. Nick came out and met with us he was very knowledgeable and helped us make an education decision on which plants were worth keeping and which ones would most likely not make the move. Its been about 6 months now and 99 percent of the plants survived the move. We are very happy and plan on using him for our landscape maintenance this coming year

I hired Collentro landscaping to install a Belgrade patio at my new home in California Maryland. They did an amazing job. We got three quotes and they were very reasonable and competitive with the other two bids but in the end we liked the personal attention we got from dealing with Collentro landscaping. The owner came out personally to meet with us after work which was the only time we were available, he made recommendations and made adjustments to the design until we landed on the final product. We appreciated his patients and hard work and will definitely use him and his team again on the next phase of our yard in the spring.

I'm a single mom and live on a very limited income. I called Collentro landscaping during the last snow storm to plow my driveway and shovel my walks. They were the only company that answered the phone and showed up when they said they would. They treated me fairly and I will definitely use again in a pinch.

Collentro landscaping was sub contracted by our company to push snow they are very professional and reliable. I would highly recommend them for all you landscape or irrigation needs.
