Professional Residential Moisture & Building Science Investigations
Identify the root cause of unwanted moisture using building-science diagnostics, thermal imaging, depressurization, moisture measurement, and long-term environmental monitoring.
Moisture Problems Are Symptoms. The Goal Is to Find the Cause.
SBC Testing conducts comprehensive, forensic building science investigations to identify the root causes of unwanted moisture in homes.
Led by BPI-certified professional Shawn Baldwin, SBC Testing combines advanced diagnostic tools including blower door depressurization, thermal imaging, data loggers, and moisture meters to pinpoint leak sources, stop structural degradation, and safeguard indoor air quality.
Problems We Investigate
Moisture can enter or accumulate in a building through several different pathways. Identifying the mechanism is essential before deciding how to repair it.
Wall Cavity & Roof Assembly Dampness
Condensation and moisture accumulation inside unvented roofs, double-stud walls, or insulated wall cavities.
Bulk Water & Envelope Intrusion
Window flashing failures, roof leaks, and basement or crawlspace water intrusion.
Wintertime Window & Ceiling Condensation
Elevated indoor humidity combining with cold thermal bridges during colder New England months.
Crawlspace & Foundation Dampness
Earth-coupled moisture drive, high humidity in unvented crawlspaces, and efflorescence on basement walls.
Diagnose the Building Before Prescribing the Repair
SBC Testing combines multiple diagnostic methods to distinguish between bulk water, air-transported moisture, vapor diffusion, thermal bridging, and mechanical factors.
Comprehensive Building Envelope Auditing
SBC Testing traces moisture back to its true source, distinguishing between bulk water leaks, air-transported moisture, and vapor diffusion.
Air-transported moisture can occur when humid indoor air leaks into cold building assemblies and condenses within framing, insulation, or sheathing.
Non-Destructive Infrared & Diagnostic Testing
Using high-resolution thermal imaging during blower door depressurization, SBC Testing can map hidden damp zones, thermal bridging, and air pathways that contribute to indoor condensation.
Material & Pinpoint Moisture Profiling
Using pin and pinless moisture meters alongside Wood Moisture Equivalent (WME) probing, SBC Testing assesses dampness levels inside framing, sheathing, and drywall.
Actionable Remediation & Building Science Solutions
You receive a detailed report outlining the investigation findings and the likely root cause of the moisture problem.
Recommendations may include practical, building-science-backed solutions to repair the air barrier, improve ventilation, correct envelope details, or address other contributing conditions.
Moisture Investigations Require Evidence, Not Assumptions
Diagnostic measurements help separate visible symptoms from the underlying building-science mechanisms causing the problem.
The Wet Spot Is Not Always Where the Problem Started
Water and moisture can move through building assemblies by gravity, capillary action, air movement, and vapor diffusion. A successful investigation looks beyond the visible damage to determine how moisture entered, accumulated, or failed to dry.

Let's Find Out Why It's Happening.
Whether the concern is condensation, hidden dampness, a roof or envelope leak, crawlspace humidity, or an unexplained moisture pattern, SBC Testing can help investigate the building and identify the likely cause.
