New Construction Defects: Why New Homes Need Inspection
A common misconception among Rochester homebuyers is that new construction homes do not need inspection because everything is new. In reality, our new construction inspections consistently find defects — sometimes more than in existing homes. Fast-paced construction, multiple subcontractor coordination, and the sheer complexity of modern home building create opportunities for errors.
Most Common New Construction Defects
In Rochester's active new construction market, our most frequent findings include improper grading that directs water toward the foundation rather than away, missing or incorrectly installed insulation, HVAC ductwork disconnections or improper sealing, plumbing connections that were not fully tightened, electrical wiring errors including reversed polarity and missing GFCI protection, and cosmetic damage from construction activities.
Grading and Drainage Issues
The most consequential new construction defect we find in Rochester is improper grading. Builder final grading often does not achieve the recommended 6-inch drop over the first 10 feet from the foundation. Settlement of backfill soil around the foundation, combined with Rochester's clay soils, creates conditions for basement moisture intrusion within the first few years. Our inspection identifies these conditions before your warranty expires.
Energy Efficiency Verification
New Rochester homes are built to current energy codes, but execution varies. Our thermal imaging identifies insulation gaps, missing vapor barriers, and air leakage paths that reduce the energy efficiency you are paying for. We commonly find insulation compressed by wiring and plumbing runs, missed cavities in complex framing areas, and ductwork leaks that reduce HVAC efficiency by 20-30%.
Municipal Inspection vs. Private Inspection
Rochester building inspectors verify code compliance at specific construction stages, but they do not perform the comprehensive evaluation that a private home inspection provides. Municipal inspectors may spend 15-30 minutes at each stage, while our final inspection takes 3-4 hours. We catch quality issues that fall between code requirements and reasonable buyer expectations.
