Bret Achtenhagen's Seasonal Services Reviews

★ 5★ 4★ 3★ 2★ 1This is my second large project with Seasonal Service. The projects required landscape infrastructure work for erecting a shed. In the most current project I worked with John Henderson on the planning and design. It started in the spring of 2025 but for various reasons on my side did not execute untill fall of 2025. John and I meet numerous times to go over the details and was patient with me as I added scope to the project. John did an excellent job on the design. The concrete crew and the landscapping crew were on time and professional. Construction as you may be aware can tear appart a lawn. Seasonal Services did an excellent job repairing the damaged areas. I am extremely satisfied with the customer service experience and with the install team. I will use them on other projects and highly recommend them for your projects.
October 10 · Richard LukaszewskiI wanted to wait for a full season of change before I wrote a review of our experience with Bret Achtenhagen's Seasonal Services. I feel that I can write an honest and detailed review at this point. We had a large project that was to be completed after our new build in Washington County. This project consisted of ground sprinklers, bed drip lines, concrete drive and stoops, several outlying beds, plantings, landscape lighting, some seed and some sod and maintenance services. Our first point of contact was Brady Achtenhagen. Brady was a prompt, professional and detail-oriented individual. We were not sure of our exact landscape design and Brady worked through several drawings with us, offering ideas and suggestions that we never even thought of. He even suggested a fencing company for us as we were installing a black wright iron fence in a dog run. The fencing company and Seasonal worked very well together. After the final design, approval and deposit; Brady set his team into motion and we were connected with Matt, the project manager. Matt is yet another prompt, professional and detailed individual. We were extremely comfortable with Matt from the beginning. We had some on-the-fly changes that Matt made work. He answered all our questions, educated us and orchestrated an perfect project on point and on schedule. He was prompt in answering phone calls and accepted on site meetings as needed. Each part of this project was followed by the next with a break in schedule or quality. Phil, the concrete manager, was a pleasure to work with and is truly an artist in concrete. After 2 winters, our drive looks like it did the first day it was installed. No cracks, discolorations or movement. Our stamped and colored concrete walk is a work of art. It is still as beautiful as the day it was installed. Phil also educated us on the care and maintenance of the concrete, and it remains in perfect shape. Martin is the irrigation manger and another detailed individual. He carefully and skillfully mapped out the irrigation and drip lines so precisely and even walked around the property with us as we drew out a map of all sprinkler lines and heads. He carefully checked each head to make sure it was working properly and reaching the areas it needed to. The drip lines were also installed, and he showed us how they worked, blow out lines and educated us in maintenance and use. The rain system was then explained thoroughly. We had absolutely no questions when Martin was done and felt comfortable and confident in using the entire irrigation system. The plantings were carefully selected and planted. We have very specific HOA regulations on the thickness of the trunks of trees as well as how many trees needed to be planted. Brady went through each planting in the beginning planning process showing us the trees we selected and what the trees would look like at maturity. We knew exactly what we were going to end up with. They planted each tree per plan, and they look beautiful. The landscape lighting was next and turned out beautifully. Each bed and tree are lit up perfectly and the fixtures look amazing. Lastly the seed and sod. We elected to sod our dog’s run. The sod went in quickly, knowing the urgency of getting it in for the dogs to have their area. Once it was installed, the irrigation was brought through the sod and tested and then we were good to go. The seed was laid and watered with the irrigation system and literally came up in weeks. A nice thick blanket of straw was laid to protect the seed and it was perfect. We also use Seasonal for our start up and shut down of our irrigation, weed and feed and reseeding of our lawn when/if needed. To wrap up this review, I would give Bret Achtenhagen's Seasonal Services a 10 out of 10 on this entire project. If home builders could run a project like Seasonal Services, it would be amazingly easy, pleasurable and stress-free to build a house. Truly an amazing experience and we would highly recommend Seasonal Services for your landscaping needs.
April 25 · Lisa PerelshteinI recently had several gardens replaced in the yard and around the house at my relatives house. Scott met me there and we discussed a plan and he helped me decide on the best course of action. Scott was very open to whatever I needed to get done. He called back several times to make sure everything was on track. When the work started I met Andy who was in charge of the project. He was very detail oriented and wanted to know about every garden and landscape problem that we were addressing. Since I don't live on the property, Andy called me several times to make sure that what I wanted saved or removed was going to happen correctly. Very professional about everything. Great service and I was extremely happy with the results. Thanks Scott and Andy...
September 04 · Rick LanduskyI can’t say enough great things about our experience with Brady Achtenhagen and the Seasonal Services team. Five years ago Brady led a major landscaping project at our new home. The project turned out beautifully and the Seasonal Services team have been excellent partners in helping us maintain the irrigation and landscaping at our home since then. The whole team is great: The phone team is always responsive and helpful. Scott and everyone in maintenance we have met over the years are always so polite and knowledgeable. And, I always know Seasonal Services will deliver high quality work that they stand behind. Recently Brady went above and beyond to help us complete an irrigation related repair and the service was excellent as usual!
June 21 · Jona MancusoSeasonal Services installed a paver patio to replace a deck in our early 90’s home. I know there are other providers in the area that may be less expensive, but we had confidence in Seasonal Services based on work they performed at a neighbor’s home. Brady was professional and provided great design advice that others did not offer during the bid stage. Their design was flexible and will allow for future additions of a sitting wall combined with a outdoor fireplace. The project manager was very accessible, reviewed progress regularly and made adjustments based on our feedback. The installation team was polite, skilled, neat and hard working. The coordination of adjustments between the PM and installation team was excellent. The job was completed in the timeframe expected while working around multiple rain days and through extremely hot weather. The completed patio exceeds our expectations.
