Home Inspections, Mold Inspections & Water Testing in Sag Harbor, NY
Sag Harbor homes are a mix—older village houses, renovated cottages, modern builds, and properties that sit closed for long stretches. That combination is exactly why a “quick look” isn’t enough. You need someone who understands what actually shows up in East End homes: humidity swings, condensation in the wrong places, seasonal patterns, and the kind of small water issues that can quietly turn into bigger problems.
Casablanca Environmental & Building Diagnostics provides home inspections, NYS-licensed mold assessments, and water quality testing in Sag Harbor and the surrounding East End. My goal is simple: give you clear information, backed by photos and practical guidance, so you can make decisions confidently—whether you’re on a real estate timeline or trying to solve an ongoing issue.
The work we do in Sag Harbor
Sag Harbor Home Inspections (Pre-Purchase & Pre-Listing)
If you’re buying, a home inspection helps you understand the home’s condition before you commit. If you’re selling, it helps you get ahead of surprises and walk into listing season with clarity.
A home inspection typically covers visible and accessible components such as:
Roof and exterior condition signals, drainage, grading, and moisture risk areas
Foundation, crawlspaces/basements, and visible structural concerns
HVAC systems, ventilation basics, and common performance red flags
Plumbing fixtures and visible piping conditions
Electrical visible components and safety considerations
Interior doors/windows, finishes, and general functionality concerns
You’ll receive a clear report that separates urgent items from maintenance items, and highlights what should be further evaluated.
Sag Harbor NYS-Licensed Mold Assessments & Testing
Musty odors and “weird smells” are common reasons Sag Harbor homeowners call. The challenge is that odor can come from several places—crawlspaces/basements, attic/mechanical spaces, HVAC ductwork, or a past leak that was never fully addressed.
A mold assessment focuses on:
A detailed visual review of moisture-prone areas (attic/mechanicals, basements/crawlspaces, bathrooms, kitchens, closets)
Observations tied to moisture drivers (humidity patterns, ventilation, condensation points, leakage indicators)
Targeted sampling when it’s appropriate for the question you’re trying to answer
Photo-supported documentation and clear next steps
The point isn’t to scare anyone. It’s to take the guesswork out of it and define a path forward—whether that’s moisture control improvements, corrective repairs, or remediation planning.
Sag Harbor Water Quality Testing
Depending on the property, water can come from a municipal supply or a private well. Either way, if you’re in a transaction or you simply want peace of mind, testing provides real data.
Water testing can be used for:
Real estate due diligence (when timing and documentation matter)
Baseline screening for homeowners and seasonal properties
Follow-up testing when concerns show up (taste/odor, staining, known risk factors)
When lab analysis is needed, results are processed through a NYS ELAP-certified laboratory, and I’ll explain what the results mean in plain language—plus what the reasonable next step is (if any).
What makes Sag Harbor different
Sag Harbor’s environment and housing stock create a few predictable patterns. These are the types of things I pay close attention to on-site:
Humidity and condensation: Coastal air + seasonal closures can lead to elevated indoor humidity. Condensation often shows up in attics, mechanical spaces, and around ductwork or cold surfaces.
Crawlspaces and basements: Even without dramatic flooding, minor moisture entry can drive musty odors and long-term air quality issues—especially when airflow and vapor control aren’t dialed in.
Renovations and “patched” leaks: Many homes have had updates over the years. I look for signs of past water events and whether the source was truly corrected or just cosmetically covered.
Mechanical systems and ventilation: Poor airflow, missing insulation, and improper condensate handling can create recurring moisture conditions that show up as staining, odor, and microbial growth.
Water quality uncertainty: With well systems in particular, testing replaces assumptions with facts.
