People are talking about Maxalea…
I am so pleased with the landscaping renovations. All of the plants and shrubs in the front, back and side are beautiful and the entire look exceeds my expectations. The layout and the choice of greens add so much to the house. Already neighbors I never knew are stopping to admire everything. Once again, Maxalea has demonstrated quality workmanship.
We all LOVE the winter plantings. We are so happy with this Maxalea situation. It has really increased our enjoyment of our home and your creativity and attention to detail is so appreciated.
I want to thank you for the marvelous landscaping job you did for me. Your plan was just what I had imagined and your engineering skills are terrific. It has been a pleasure to work with you and I am as happy 14 years later as I was the very first year.
