Gallivan was the lead in developing a concept and plan for my backyard. They worked with me to envision how hardscape, landscape, and pool design could come together beautifully. They oversaw all aspects of the project and were completely reliable regarding the timing and buildout of the design. They were always responsive to my concerns and I enjoyed working with them. I wouldn't hesitate to recommend Gallivan to anyone contemplating work around their house.

I have nothing but praise for the Gallivan Corporation. The landscape designer who I worked with was professional and creative. He listened and responded with detail to my ideas. He was so easy to work with and educated me every step throughout the project. The Gallivan team has a work ethic next to none! They stood by their work and made sure everything was executed with the highest quality. Don’t hesitate to contact them and you will see for yourself!

The Gallivan Corporation was absolutely fantastic. We used them to redo our front steps and our back patio. The design team was professional and fantastic and worked with us to make sure we were getting exactly what we wanted. When it came down to the construction, the team was absolutely amazing. Both jobs were done in one week with minimal interruption to our daily lives. Love them and plan to use them again in the future.

Gallivan redid our backyard. The work was done in an excellent manner - on budget and on time! The team on site was very tidy cleaning up the site every day before leaving for the day. We can recommend Gallivan highly!

Gallivan Corporation did my father's backyard and turned it into an entertaining space for all to enjoy. Richard with the design team goes above and beyond to make the design perfect for the space. Gallivan also does my year-round landscaping and lawn care needs

The team at Gallivan take pride in their work. Our project, overseen by Bryan Anderson, is nothing short of spectacular. Raphael and his skilled crew delivered throughout, from tear-down to rebuild. In fact, every member of the crew was courteous and professional. The work was completed on-time, as described and with constant communication throughout. No question or concern was ever too unimportant and an answer, solution or suggestion was always provided. Would highly recommend them for any outdoor project.

I couldn't be happier with the paver firepit patio installation done by Gallivan! They did a fantastic job, exceeding my expectations. The craftsmanship is impeccable, and the patio has become the focal point of our outdoor space. Highly recommend their services!

From Maggie who came out to provide an estimate, to Jason and his crew to installed everything and Amanda in the office, the entire team at Gallivan was a pleasure to work with. Jason and his crew did an awesome job of not only installation but also education for my wife and I for the caring of the new hedges they installed. I would highly recommend them to anyone in the area looking to complete a landscaping job!
