“When we decided to build a house we had no doubt in our mind that we would go through St. Rosa Lumber because of our previous experiences with them as well as being a family friend. Working with Jason as the general contractor was amazing. We had heard many stories from others that went elsewhere about how stressful their experiences were building. We did not experience that at all. Their team and employees were amazing. Everything occurred right on time, there was never delays, and the job site was always clean and safe. They took pride in ensuring that our home was built with quality. We have highly recommended them to many others and will continue to do so. There’s no doubt that we would choose St. Rosa Lumber again for all our future projects.”

“St Rosa Lumber and Arnzen Construction did an outstanding job designing and building our lake home. Beginning with the design process through construction they were easy to work with and offered excellent ideas to enhance our home. It was very helpful to use their local office and showroom to make our material selections. The work crew provided excellent craftsmanship and were focused on completing the project on time and within budget.

We enjoy our home every day and would highly recommend St. Rosa Lumber for your next project.”

“I had relied on countless testimonials and referrals when deciding on St. Rosa Lumber for my project. Not only were my expectations met, the stresses of building, decision-making and the wonder if things would get done were eliminated due to the quality and craftsmanship of your company. While my project was the first time the general contractor I was using had used St. Rosa Lumber, he continued to use them for other projects following because of the reputation and service. A job well done.”
