Syosset was built out in the 1950s and 60s with ranches, split-levels and colonials on quarter- and half-acre lots — which makes it one of the best places on Long Island to add space instead of moving. Full dormers that turn a ranch into a two-story home, second-story additions over the garage, rear extensions for kitchens and family rooms, and open-concept renovations of split-levels are the projects we do most here. We have completed dormer additions and full general-contracting projects for Syosset homeowners, and their reviews are below.

The difference with Cabra Prestige Group is that the crew that frames the dormer is the crew that roofs it, sides it, sheetrocks it, tiles the new bath and paints the finished rooms. One schedule, one standard, one point of contact. On a dormer that means the new roof ties cleanly into the old one, the siding matches, and the finish inside is seamless — no handoffs between five subcontractors.

Syosset permits through the Town of Oyster Bay Building Department. We prepare the plans with your architect and engineer, submit, and schedule every inspection — framing, insulation, plumbing, electrical and final — through the certificate of completion.

Permits: Town of Oyster Bay Building Department. Also serving Woodbury, Jericho, Plainview, Hicksville, Oyster Bay and Muttontown. Licensed & insured · English & Spanish.

Cabra Prestige Group did an outstanding job on our dormer addition. Marcos managed every part of the project professionally and kept us updated throughout. The finished space looks like it was always part of the house.

Questions, answered

Hiring a contractor in Syosset?

Straight answers for Syosset homeowners. Anything else — call or text (516) 343-2806.

How much does a full dormer cost in Syosset?
It depends on the size, whether the existing foundation and framing can carry a second story, and the finishes inside. After a free on-site visit we provide a detailed written estimate so the number is real before you decide.
Can we live in the house during a dormer?
Most families do, with a staged schedule — we keep the house weather-tight and the living areas usable as long as possible. We will tell you honestly what to expect for your specific project.
Do you handle the Town of Oyster Bay permits?
Yes — plans, submission, the permit under our license, and every inspection through the certificate of completion.
