Notes
- Service-area company: its own site publishes no street address on the pages opened; it describes itself as a Merrick company serving all of Nassau. A Hempstead address appearing in directory results was NOT confirmed on its own pages and is not used here.
- Years conflict on its own site: since 2011 and over 15 years versus 25 years of local experience and serving Merrick and Nassau County for 25 years. No single figure is published here.
- License: only claims of being a licensed contractor handling permit requirements and of licensed, insured professionals. NO number published.
- No rating with a count: its own site mentions 150+ positive customer reviews and 500+ completed projects, with no star figure, which is not a rating with a count.
- No fixed price is published; only ranges that conflict between its own pages, quoted in the cost guide and labeled as conflicting, and a free estimate.
