Home Inspections in Greenwich, CT from a NY & CT Licensed ASHI Inspector
Fairfield County is EPA radon Zone 1. Backcountry wells and shoreline houses are two different jobs.
Fairfield County is EPA radon Zone 1, and about half of Greenwich homes tested over ten years exceeded 4.0 pCi/L — so radon measurement rides along with the visit. Chris Long is licensed in NY & CT, an ASHI member, with more than four decades of inspections.

Buyer's Inspection
The full working-over of the house you are under contract on: structure, roof, electrical, plumbing, and mechanicals, plus the well, septic, or shoreline questions that come standard in this town. Chris walks it with you and explains each finding at the spot where he found it. The photo report follows within 24 hours.
Pre-Offer Walkthrough
High-stakes listings move fast, and sellers do not always wait for a contract period. When you need to bid before anyone else does, Chris walks the property with you first and gives you his read on the big-ticket systems, so your offer is informed instead of hopeful.
Pre-Purchase Inspection
A complete pre-closing evaluation with radon testing built in — non-negotiable in Zone 1 Fairfield County. Water quality, septic evaluation, and mold checks fold into the same appointment, so nothing gets deferred until after you own the problem.
New Construction Inspection
Large new builds and whole-house renovations are common here, and fresh drywall hides rushed work behind expensive finishes. Chris inspects new construction before the closing walkthrough so punch-list items get corrected on the builder's schedule instead of yours.
Pre-Listing Inspection
Sellers use this to find the surprises before a buyer's inspector does — a failing multi-zone system, a well yield problem, or moisture history at the shoreline. Finding it first lets you repair on your own timeline and negotiate from strength.
Yearly Maintenance Inspection
Estates with wells, septic fields, generators, and multi-zone HVAC earn an annual once-over. Chris checks the systems that fail quietly and hands you a prioritized list so small repairs stay small instead of compounding across a big property.

- Routine radon testing in Zone 1 territory — folded into the same visit, not billed as a separate errand
The Town of Greenwich reports that radon figure publicly. Beyond the air test, Greenwich is two markets: backcountry estates on private wells and septic, and Cos Cob, Riverside, and Old Greenwich where moisture and flood proximity lead.
Backcountry Greenwich runs on private wells and septic, with houses large enough that mechanical systems become their own inspection chapter — multiple HVAC zones, standby generators, pool equipment. Down the hill, Cos Cob, Riverside, and Old Greenwich trade wells for municipal water and take on waterfront questions instead: flood proximity, salt-air corrosion, moisture histories. Chris scopes each inspection to the market in front of him, and the same dual-state license covers buyers who cross into Westchester — see our Rye, NY home inspection page for the Sound-shore comparison.
One appointment covers the whole checklist. While Chris works through the structure and the roof, the same visit folds in radon testing — expected practice in Zone 1 — plus a mold assessment, well or tap water quality testing, and a complete heating and cooling evaluation. One scheduling call, one report back within 24 hours.
What We Commonly Find in Greenwich Homes
Five patterns Chris keeps meeting across Connecticut's largest town.
Zone 1 radon, taken seriously
Fairfield County sits in EPA radon Zone 1, and Greenwich's own decade of test data shows roughly half of tested homes exceeding the 4.0 pCi/L action level (Town of Greenwich). Radon measurement is part of the standard visit here, not an optional add-on.
Private wells and septic in backcountry
Outside the served areas, backcountry houses draw their own water and treat their own wastewater. Chris evaluates well output and water quality, looks over the septic field for distress, and tells you plainly what you inherit when the town does not operate the infrastructure.
Multi-zone HVAC on large houses
Big Greenwich houses often run several heating and cooling zones, plus air handlers in attics and crawl spaces that rarely get visited. Each zone is a mechanical system with its own age and failure modes. Chris evaluates the whole plant and flags which components are near end of life.
Waterfront moisture and flood proximity
Cos Cob, Riverside, and Old Greenwich parcels sit near tidal water. Salt air corrodes fasteners and equipment, coastal storms drive moisture into foundations, and FEMA flood zones shape insurance. Chris documents water evidence, drainage, and flood-zone context so you can price the risk.
Oil tanks on older estates
Estates that predate natural gas conversion sometimes still carry buried or abandoned oil tanks with no paperwork trail. Tank leaks are expensive to remediate after closing. Chris flags tank evidence during the visit while you still have leverage to raise it with the seller.
