"We have worked with Andrew and his crew since 2006 over various renovation projects. He built an outdoor fireplace ,stone wall and wood deck. He installed a brick driveway and path and added new windows in our first project. It totally changed the character of our home. He is attentive and punctual and honest as are the workers he hires. We hired him to install a brand new kitchen and renovate our first floor from flooring to painting. We are thrilled with the work and again had a seamless experience with Andrew. He is currently renovating two bathrooms for us . He is great at providing a detailed contract and estimating the cost of construction. When we needed some structural and foundation work in our basement, he educated himself on what needed to be done and secured our basement. We cannot say enough positive words about Andrew and his responsiveness and his integrity."

"Andrew Sebastian has completed several projects at our home over the past seven or eight years. These have included installing fencing and a trash enclosure, renovating our front and back yards, designing and installing a drainage solution for our back yard that actually works, installing stone walkways and a new stone patio with a natural gas firepit in the center. He is very attentive to the quality of the work performed by his crew, patiently answers questions and makes sure the homeowner is comfortable with the work to be performed before starting and throughout the project. Andrew is a pleasure to work with, and I highly recommend him. We look forward to working with Sebastian Design Build in the future."

"We have used Sebastian Design Build for a variety of projects ranging from a total backyard renovation (including a pizza oven, landscaping, pool installation, custom garage doors) to smaller projects inside the house. Andrew and his crew are attentive, honest and responsive. Andrew’s team created beautiful stonework and landscaping - I love looking out at my backyard and spending time there. In addition, Andrew has provided creative solutions to typical things that arise when you own a house that is 100 years old. I heartily recommend Sebastian Design Build to anyone who wants an honest, reliable team who do top notch work."

"Recently, Andrew created a landscape design that was exactly what I had wanted. He installed beautiful stone steps and planters along with our front porch. Our front entrance is very steep and I thought there is no way to fix that, but Andrew did and beautifully! His crew is polite and professional. You can tell they are highly skilled. Even years later, their craftsmanship has held up. Their stone work is amazing! Andrew is easy to work with and has done several jobs for me over the years, inside the house and out. He is the only person I call for my home improvement projects."
