Leak Investigation Services
Certified Testing To Identify Building Envelope and Curtain Wall Water Infiltration
ONE Glass Service specializes in leak diagnostics and repairs for storefront and curtain wall systems, ensuring water infiltration issues are identified precisely and resolved correctly the first time. Water infiltration in a commercial building is rarely caused by a single drip—it often results from complex failures within the curtain wall, storefront, window systems, sealants, or adjacent façade connections. Using certified industry testing to pinpoint the exact source of leaks, we provide clear, actionable repair recommendations.
When Leak Investigation Is Needed
Building envelope leaks can occur unexpectedly or worsen over time. Common signs include:
- Water staining on drywall or ceilings
- Moisture or puddling near windows or curtain wall systems
- Drafts or air infiltration during storms
- Rust, mold, mildew, or musty odors
- Deteriorating interior finishes or warped materials
- Electrical issues caused by hidden moisture
Prompt investigation prevents further structural deterioration and reduces long-term repair costs.
Our Leak Investigation Process
- 1. Initial Review & Interior Assessment
We inspect affected areas, review visible damage, and trace moisture patterns to identify likely infiltration paths. - 2. Exterior Envelope Evaluation
Our team examines curtain wall joints, storefront connections, glazing seals, perimeter caulking, flashings, and system interfaces. - 3. Certified Water & Air Infiltration Testing
We perform AAMA and ASTM-standard tests—including chamber testing, spray rack testing, and air infiltration assessments—to replicate real-world conditions and confirm the failure points. - 4. Source Identification & Documentation
Once the leak source is identified, we document findings with photos, measurements, and testing results for clarity and verification. - 5. Detailed Repair Recommendations
You receive a full written report outlining the root cause, recommended repairs, and an estimate tailored to your building’s needs.
