Do you build in Old Bethpage?
Yes — Old Bethpage is firmly inside our service area. We hold Nassau County HIC #198901 and pull the applicable town-level permit for Old Bethpage jobs. No travel fees within Nassau.
Do I need a permit for a dormer or addition in Old Bethpage?
Yes, for almost any structural dormer or addition in Old Bethpage. Our permit coordinator, our permit coordinator, manages the filing end-to-end — from drawings through inspection sign-off. Permit costs are itemized in the estimate, not a surprise.
How long does an addition take in Old Bethpage?
Design and permitting: 2–4 months. A typical dormer runs 6–9 weeks to completion after permit issuance. A second-story addition is 4–6 months. New construction runs 12–16 months. We build Gantt charts at the scoping visit.
Can you work on older Old Bethpage homes?
Absolutely — it's a lot of what we do. Pre-war colonials, mid-century Capes, and ranches all benefit from additions. We match existing soffits, trim profiles, and rooflines carefully. The owner reviews every heritage-match detail personally.
