Frequently Asked Questions About Building in Port Washington

Do you build dormers in Port Washington, NY?

Yes — Port Washington is an active area for Long Island Homeworks. We hold Nassau County license H-1609230000 and have completed dormer additions on Port Washington's original 1920s–30s colonials and expanded capes along Shore Road, Port Washington Boulevard, and the waterfront streets in Sands Point adjacent neighborhoods. Port Washington falls under the Town of North Hempstead building department — we manage all permits end to end.

How much does a dormer cost in Port Washington, NY?

Dormer additions in Port Washington typically run $68,000–$115,000 depending on size and scope. Original 1920s–30s colonials with lath-and-plaster walls and custom trim profiles cost more to match than post-war construction. A full shed dormer on a 1930s Port Washington colonial typically runs $75,000–$98,000 with permits. Frank provides a fixed-price written contract after the scoping walk-through.

Do I need a permit for a dormer in Port Washington?

Yes. Port Washington is in the Town of North Hempstead building department jurisdiction. Structural dormer additions require a building permit. Properties in Sands Point (an incorporated village) have their own separate building department. Lisa, our permit coordinator, handles all drawings and filings for both jurisdictions. Typical turnaround is 4–8 weeks.

How long does a Port Washington dormer project take?

Design and permitting takes 8–14 weeks in Port Washington. Once permits are issued, construction on a typical shed dormer runs 6–9 weeks to completion. You receive a Gantt chart at the scoping visit with specific milestone dates.

What dormers contractors serve Port Washington, NY?
