Quality Building since 1945

Seifert Construction is a family-owned operation that has been in business for over 60 years. Over time the scope of the company's work has broadened but the same commitment to quality exists as it did some 60 years ago. Now in its 3rd generation Seifert Construction has established itself as one of the elite high end custom home builders on the North Fork.






1st Generation
Seifert Brothers was established in 1945 by brothers George and Frederick "Fritz" Seifert. The company was based in Rockaway and focused on custom copperwork. Seifert Brothers is responsible for much of the detailed copperwork for many of the estates on the North Shores gold coast.

2nd Generation
Seifert Brothers was changed to Seifert Construction in 1959 by Fritz's son Frederick. It was at this time the company expanded into all phases of custom carpentry and high end home building. The company was based in Smithtown and did a majority of its projects in the Hewlett and Brookville areas.
In the early 80's Seifert Construction established its own custom cabinet and mill shop to better control quality on it's projects.






3rd Generation
Today, Fred Sr. is still active in the company, but his two sons, Fred and John continue the Seifert legacy of providing their customers outstanding quality and care in all their custom building projects. The company is now based in Mattituck, N.Y. and has been building high end custom homes on the North Fork for over 10 years.
