Client Testimonials

When it was time to build our home, we knew we needed to choose a builder who we could trust. We had already used Jeff for a much smaller project at our previous house and could sense from that interaction with him that he would be our partner in this new endeavor. Jeff is a man of his word and continuously communicated with us so that we would stay on schedule. He has a wealth of experience and gave us excellent advice when we needed to make major decisions. When we first met with him, he told us that once he becomes our builder, he will be that for life. And that he has. We built our home in 2006 and he is someone we have turned to for help or advice over the last 11 years.

Most people say that building a home was one of the most stressful events in their life. We can truly say that it was a pleasure to work with Jeff and because the experience was so enjoyable and rewarding, we are currently in the process of building another home with him. Jeff is such a forthright, honest, sincere man and the builder any person would be fortunate to have.

When we embarked on building our new home on LBI, there was no question that we would use Jeff Seddon as our builder.  Jeff has a solid reputation one of the best builders on LBI and we learned there’s good reason for that, he managed our entire project, start to finish, flawlessly!
