Wayne Ketner at Peninsula Construction Services is the real deal. Some people throw the word legacy around, but Wayne is truly building one—making a lasting impact on our county through his unmatched dedication, love, and care for his craft. If you're in the construction field and haven’t connected with him yet, I highly recommend reaching out. And if you're considering a home project, whether inside or out, Wayne is the person to talk to. His attention to detail and commitment to excellence set him apart.Posted on Google![]()

From start to finish, Wayne and his team were professional, reliable, and easy to work with. He listened to my ideas, provided expert advice, and helped me make the best decisions for my home. The quality of his craftsmanship is outstanding, and the attention to detail really shows in the finished product. The entire project was completed on time and within budget, with minimal disruption to my daily life. Wayne and his team were respectful, cleaned up daily, and kept me informed throughout the process.
