WOW! We had a vision of how we wanted our office to look, and they blew us away! We worked with their designer, who created 3D mockups of the layout, number of shelves, color, and closed cabinets with measurements for everything. After the cabinets arrived, we worked with their project manager and Austin, who had constant and consistent communication with us on timelines, expectations, etc. > > They professionally managed, installed, and developed our office built-ins, desks, etc. We're SO HAPPY with the results that we're going to use their services for several other projects we want done in our home. They are a pleasure to work with and professional from start to finish! I highly recommend them for any remodeling or other types of work in your home! OUTSTANDING!!!! **★★★★★ — HU-891931011, Feb. 2020** > A1 is my go to construction company! I never have to wonder if the project will be done professionally. Austin has an eye for detail and communicates status of project well. Every project I have hired A1 for has gone smoothly and looks amazing! I have recommended A1 many times and will continue to do so! **★★★★★ — Jonathan Bloch, Sept. 2019** > Austin is is like some sort of contractor prodigy or something, a true genius and just an amazing nice guy to work with. Put him on your preferred hire list if you can get him. **★★★★★ — Rob Wheeler, Sept. 2019** > Austin did a great job for us doing several remodeling projects at our home. Among other projects, Austin and his team replaced the 1970s tile in our bathroom shower, and also replaced and repainted exterior siding that had rotted over time. > > I was so impressed with Austin and his quality of work that I hired him to replace tile in two bathrooms at my Mother's home. > > Austin does a great job and works hard. He is very professional, completes projects on time and his pricing is reasonable. I would recommend him for your next project. > I own a swimming pool construction company and a mobile home park so I have had some experience with contractors. **★★★★★ — Mike Duggan, Sept. 2019** > Austin has always been a great contractor for me and my clients. He shows up when he says and does a good job at a fair price. **★★★★★ — Erin Hothan, Sept. 2019** > We have been more than thrilled with the work that A1 has done for us and we will continue to have projects for him in the future. He has been honest, hard working, very easy to get a hold of, and professional. His staff has been equally excellent as well. We are looking forward to keeping him as a part of our family and wish him continued success. Clients for life. **★★★★★ — Nathan Robinson, Sept. 2019** > Austin did a great job and I have referred him to other friends and family.
