Most of the time, they whisper\u2014through subtle stains, swollen trim, soft drywall, or weird thermal camera patterns that say, \u201cWater\u2019s been here.\u201d And that\u2019s what I\u2019m trained to look for. Not just puddles on the floor, but the symptoms that suggest a slow leak is happening behind the scenes. Because by the time water is visibly dripping, the real damage is already done. What Triggers Concern During a Home Inspection? I\u2019m constantly evaluating the entire property for water intrusion risk. That includes: Grading issues: If the yard slopes toward the house instead of away from it, it\u2019s like a welcome sign for water intrusion into the foundation or basement. Unsealed penetrations: Gaps around plumbing, wiring, HVAC lines, dryer vents, and even cable boxes\u2014if not sealed\u2014let water and pests in. Window and door flashing: If improperly installed or deteriorated, rainwater can slip behind siding or framing. Look for bubbling paint, soft drywall, or rusty metal corners. Staining or discoloration: I\u2019m trained to recognize water stains even after they\u2019ve been painted over. (Yes, there\u2019s a difference in texture, sheen, and absorption.) Thermal anomalies: A thermal camera can detect cooler or warmer spots than expected\u2014often indicating moisture behind the wall, especially if it\u2019s rained within 24 hours. Where We Find the Most Leaks Leaks aren\u2019t just a roof thing. I\u2019ve found water intrusion in some of the most common (and surprising) spots: Below windows and doors Basements or crawlspaces with poor drainage Bathrooms with unsealed tubs or tile grout Attics with old flashing or missing shingles Inside garages where grading slopes inward And sometimes it\u2019s not a leak\u2014yet. It\u2019s a condition that\u2019s practically begging to become one. Like that HVAC line entering the home with a 1\" gap around it, or that flower bed you lovingly built that now holds water against the siding. I\u2019ll call that out before it causes trouble. What I\u2019m Looking For\u2014And What I\u2019m Not \u2705 I\u2019m looking for: visible damage, water stains, thermal anomalies, and entry points where water could get in. \u274c I\u2019m not: performing moisture meter readings behind every wall, or predicting future leaks with certainty. This is a visual inspection\u2014not a waterproofing guarantee. What Happens Next? If I flag active or suspicious leaks, here\u2019s what I recommend: Get a contractor or roofer to evaluate and possibly open the wall or ceiling. Check the grading and downspout placement\u2014simple fixes often prevent big damage. If thermal imaging suggests a problem, verify with a moisture meter or invasive testing (beyond inspection scope). FAQs: Active Leaks During Home Inspections Can you confirm if a wall has a leak? We can identify signs and patterns that suggest moisture, but we don\u2019t cut walls open. Thermal cameras help, but confirmation often requires further testing. What are the biggest causes of water intrusion? Poor grading, unsealed exterior penetrations, damaged roofing or flashing, and deferred maintenance. Water always takes the easiest path in. Why do some leaks go unnoticed for so long? They often start small\u2014like a slow drip behind drywall. By the time you see stains, warping, or paint bubbling, water has likely been there for weeks or months. Can leaks be hidden even if the inspection finds nothing? Yes. We only evaluate what we can see. If a leak is behind finished walls or ceilings and hasn\u2019t caused visible symptoms yet, it may go undetected without invasive testing. \u2192 Next up: Post 40: Why You Should Attend Your Home Inspection Walkthrough \u2190 Previously: Post 38: Potential Mold \u2014 What We Can Say (and What We Can\u2019t) Curious what it\u2019s like to schedule your own home inspection with us?","datePublished":"2025-07-16","dateModified":"2025-07-16","author":{"@type":"Person","@id":"https:\/\/homeinspectionsovercoffee.com\/author\/curtis\/#Person","name":"Kloc Curtis","url":"https:\/\/homeinspectionsovercoffee.com\/author\/curtis\/","identifier":6,"description":"Curtis Kloc is a U.S. Navy veteran and seasoned entrepreneur with over two decades of experience in business development, inspections, and technical systems.
