Sea-Dar is committed to developing trusting relationships with our clients that last long after the project has been completed.

For more than 25 years, Sea-Dar Construction has been building a wide range of construction projects: from luxury urban residences and fine suburban custom homes, to large, technically complex institutional and commercial structures, each is managed with the same commitment to quality and customer service. Whether it is new construction, conversion, renovation, or restoration, we consistently exceed the expectations of our clients.

‘Building Trust’ is not a slogan; it is at the core of every project we undertake.
Communication and transparency is a priority when we build.
