Colonial Landscape Service has been making Bay Area properties more beautiful for over ten years. Owner Dave Tardiff received his degree in Horticulture and Landscape Construction in 1986. He served as co-owner of another landscaping company prior to creating his own business in 1997.

Colonial Landscape Service provides complete design, consultation and construction services such as hardscaping, pond construction, irrigation and drainage systems, exterior lighting, planting and mulching. Their nursery is stocked with everything you need to make your landscape an oasis. If they don't have what you're looking for, they can order it for you.

Depending on the project, Colonial Landscape Service will maintain it for 90 days free of charge. During that time they will inspect any equipment they've installed, trim and edge turf, apply fertilizer, and prune/weed as necessary. This will ensure that your new landscape is healthy and thriving.

"His work was excellent. In fact, we referred him to two other people. I work in retail. I was telling someone about what a wonderful job he did and they used him. They live two cities away and he was able to get to them. Now, they are raving about the good work."
