Denise Renella
We had a “huge” project- rotten deck and decayed terraced retaining wall. We had several bids; we chose SI Outdoor. We are so glad we did!
Jeff Rose presented a clear design option. His extensive knowledge and experience eliminated any apprehensions I may have had. He explained everything he did and why. He is a leader and has a clear vision for amazing finished product. We love the work he and his crew did! It is beautiful, solidly constructed. Thank you Jeff and your team. Your incredible work will last a life time. We look forward to enjoying your masterpiece for generations to come.
With Gratitude,
Aaron and Denise

Amy Bridgeo
SI Outdoor just completed our landscaping project at our new house. With a large yard and a limited budget, Jeff worked with us to get the most bang for our buck. The project was done on schedule and exceeding our expectations in terms of quality. The crew was friendly and professional and even put up with our obnoxious dog! We will be calling Jeff for all our future landscaping needs!

Alonzo Benavides
Redid our patio with concrete. Also had some custom work to make a pizza oven area and seat wall. It turned out amazing. Not the cheapest option but they work fast and provide a professional/high quality finish.
