For pre-purchase property evaluation in La Mesa, Real Estate Inspection Services operates from a suite at 7840 El Cajon Blvd near Grossmont College. Inspection reports cover all five major systems — roof, foundation, plumbing, electrical, and HVAC — using the same code-compliance framework that firms like The Permit Pro Consultant apply to permit submittals in the area. Add-on testing includes mold sampling, lead-based-paint screening for pre-1978 construction, pool and spa equipment evaluation, and insulation assessment. Sewer-scope inspections supplement the standard visual walkthrough by sending a camera through the main lateral, identifying root intrusion or cast-iron deterioration that specialists such as John Padilla Plumbing, Sewer and Drains can then address on the same property. Infrared thermal imaging detects moisture intrusion behind drywall and hidden electrical hot spots that fall outside the scope of a standard visual-only CREIA walkthrough.
