It all began with the desire to build a company that is about family

At 4K Builders, we’re more than just a construction company, we are a family legacy in the making. Founded by the Seamus in the heart of the Southern Maine’s seacoast region, 4K Builders was created with a vision to build not only exceptional homes and buildings, but also a lasting tradition that can be passed down through generations.

Our name, 4K, reflects the four members of our Kidney family whose values — hard work, integrity, and craftsmanship — are at the core of everything we do. As a family owned and operated business, we take pride in delivering quality construction with a personal touch. Whether it’s a new home, renovation, or commercial space, we treat every job as if we were building for our own family.

Let us help bring your vision to life — the 4K way.
