Communities & Neighborhoods We Inspect in Nassau County
Square One provides 7-day-a-week licensed home inspections across all neighborhoods and townships in Nassau County, including:
1. Central Nassau: Levittown, Westbury, Hicksville & East Meadow
As a Levittown-based home inspection company, we know the anatomy of Central Nassau’s post-war housing stock inside and out. Built largely between 1947 and 1960, original Levittown Capes and Ranches were constructed on concrete slabs with copper hot-water radiant heating coils embedded directly inside the slab.
Over 70+ years, almost every home in Levittown, Westbury, and Hicksville has undergone major structural additions—rear dormers, second-story expansions, garage conversions, and kitchen bump-outs. We inspect header spans, roof framing tie-ins, abandoned underground heating oil tanks, and use infrared thermal cameras to scan in-slab radiant heating loops for hidden leaks.
Always verify whether original in-slab copper heating coils are still active or have been properly bypassed with baseboard convectors, and check for buried or enclosed fuel oil tanks.
2. Western Nassau: Valley Stream, Elmont, Lynbrook & Garden City
Western Nassau features a dense mix of 1920s–1940s Colonials, brick Tudors, and Cape Cod homes on full basements. Because these homes are approaching 80 to 100 years old, our inspection zeroes in on aging cast-iron waste lines, galvanized water supply piping (which restricts water pressure), ungrounded 2-prong or cloth-sheathed electrical wiring, and Federal Pacific "Stab-Lok" breaker panels.
We also closely inspect basement foundation walls and sump pump systems for hydrostatic water table intrusion after heavy rains.
3. North Shore Nassau: Great Neck, Glen Cove, Manhasset & Roslyn
The Gold Coast and North Shore of Nassau County feature larger custom Colonials, historic Tudors, and hilly terrain with steep grades and retaining walls. Multi-zone hydronic boilers, slate or cedar shake roofs, complex roof valleys, and older stone/masonry foundations require an inspector with deep mechanical engineering experience.
In hilly North Shore areas with glacial granite deposits, we also strongly recommend pairing your inspection with a 48-hour Continuous Radon Monitor test and a thorough Wood-Destroying Insect (WDI) evaluation.
4. South Shore & Barrier Island: Long Beach, Freeport, Roosevelt & Merrick
Properties along Nassau’s South Shore and barrier island face high coastal water tables, salt-air corrosion on HVAC condensers and electrical meter pans, and FEMA flood-zone considerations. In Long Beach and Freeport, we carefully inspect crawlspaces, structural wood pilings, sill plates, subfloor moisture levels, and exterior decks for rot and subterranean termite activity.
What We Watch For in Nassau County Homes
Local soil conditions, proximity to coastal water, and construction eras vary significantly across Nassau County. Here is how we tailor our inspection focus:
| Towns / Neighborhoods | Dominant Housing Stock | Frequent Inspection Findings | Recommended Inspection Package |
|---|---|---|---|
| Levittown, Westbury & Hicksville | 1947–1960 Post-War Capes, Ranches & Split-Levels | In-slab radiant heating leaks, buried oil tanks, unreinforced dormer framing, slab expansion joint termites | Thermal Imaging + Termite (WDI) Inspection |
| Valley Stream, Elmont & Lynbrook | 1920s–1950s Colonials & Tudors on Full Basements | Federal Pacific panels, aging steam/hydronic boilers, basement seepage, chimney mortar deterioration | Full Home Inspection + Radon & Termite |
| Great Neck & Glen Cove (North Shore) | Historic Estates, Custom Colonials & Split-Levels | Slate/complex roof flashing leaks, multi-zone HVAC issues, retaining wall movement, elevated basement radon | 48-Hr Continuous Radon Test + Full Inspection |
| Long Beach, Freeport & Roosevelt | Coastal Bungalows, High-Ranches & Elevated Homes | High water-table crawlspace moisture, salt corrosion on electrical/AC units, wood-destroying insects in damp sills | Moisture/Thermal Scan + Mold & Termite (WDI) |
