🔎 New Construction Tip from Cypress Property Inspections Assessments & Consulting dba Cypress Mitigation
During the construction phase of a home, there are small details that can make a big difference years down the road.
One of the most overlooked areas we see during inspections is unsealed plywood/OSB joints and window track gaps inside exterior walls. These seams may look harmless during framing, but once HVAC systems are installed, they can create hidden problems.
⚠️ Why sealing these areas matters:
• Prevents air infiltration that can disrupt HVAC efficiency
• Reduces the risk of humidity intrusion into wall cavities
• Helps stop condensation forming behind drywall
• Protects insulation from moisture buildup and microbial growth
• Improves overall indoor air quality
🛠 Best Practice During Construction
At Cypress Property Inspections, we recommend applying a rubberized sealant (or elastomeric air seal) along:
✔ Plywood / OSB panel joints
✔ Window rough openings
✔ Window track gaps
✔ Penetrations for electrical or plumbing
This simple step creates a tight building envelope before insulation and drywall go in.
When HVAC systems begin conditioning the air inside the home, a properly sealed structure prevents moisture migration and long-term structural or mold issues.
🏠 Building it right the first time protects the home for years to come.
If you’re building, buying, or renovating, we can help ensure the structure is sealed, ventilated, and performing properly before problems develop.
