Seifert Construction
Growing up in the construction business with our father, we realized at a very young age that we wanted to continue the "Seifert Building Tradition" that has been in our family for three generations. As partners we shared the same dreams, visions and passion for what we found was our calling. Together we have been able not only to build clients homes but to turn their dreams into reality.

As seasons change and time goes by, it gives us great satisfaction to reflect back on all the amazing projects we've been a part of and the wonderful people we worked with along the way. We feel fortunate that we are able to live in the community, raise our families here, and to help beautify the area.

Seifert Construction has a long-standing reputation for building high-end luxury homes on the East End of Long Island. We pride ourselves on building the finest coastal homes in the area. Building on the East End of Long Island we are sensitive to the surrounding architecture and, it is, for this reason, many of our projects are a renovation of smaller, simpler homes.
Services
Seifert Construction is a family owned and operated third generation, full-service construction company serving the East End of Long Island. We specialize in building high end, luxury custom homes, and renovations where only the finest materials and highest quality craftsmanship is accepted. With over 200 completed projects in the last 20+ years, we have built a reputation as one of the premier custom home builders on the East End.
We take great pride in knowing every single house we build is a true representation of our company. Only the best materials and highest quality craftsmanship go into each Seifert Construction home. As home builders, we have forged relationships with the finest subcontractors on Long Island and have created a family of craftsmen all focused on the same vision.
You can't blame custom homebuilders Fred and John Seifert for being fussy about building materials. The brothers own and operate Seifert Construction, a third-generation eastern Long Island-based homebuilder specializing in second and third homes valued up to $10 million. They deliver about 10 projects a year.
When I first considered building a custom home, I thought if the motion picture Mr. Blandings Builds His Dream House. Perhaps you remember the story of a contractor and his subcontractors, continuously conspiring to make Cary Grant's life and endless series of catastrophes. Building my home with Seifert Construction has, in fact, been one of the most incredibly exciting and really fun experiences of my life.

Report
My wife and i decided to purchase a home on the north fork. But after renovating several homes in the past we did not want to do it again. We looked at 40 or 50 homes over the next year before deciding in order to get what we wanted we had to do it again and ended purchasing a home that needed a gut renovation. We found our home and selected an architect. The architect recommended Seifert construction. After going through the bidding process we decided we were most comfortable with John and Fred Seifert. They understood the project and submitted a fair and comprehensive proposal. John and Fred
