Meigel Dormers & Extensions

Meigel Dormers & Extensions builds dormer additions and home extensions for homeowners across Suffolk County and Long Island. Based in Lake Grove, NY, we specialize in shed dormers, gable dormers, hip dormers, and full second-story additions on Cape Cod, ranch, colonial, and split-level homes built throughout the 1950s–1970s postwar era. Our home extension services include rear additions, side extensions, kitchen bump-outs, in-law suites, and second-story pop-tops. Every project includes architectural design, structural engineering, and full permit management through the Town of Brookhaven, Suffolk County, and surrounding Long Island municipalities. Licensed and insured, we provide fixed-price written estimates with no hidden fees.
