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.

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!

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!
