Why DFW Caulking Fails Faster
North Texas's wide temperature swings between summer heat and winter freezes cause repeated expansion and contraction in caulking material, accelerating cracking and shrinkage compared to more climate-stable regions.
What to Check During Routine Maintenance
Window and door perimeters, siding and brick expansion joints, and any exterior penetration points should be visually checked for cracking or gaps at least once a year — ideally during a spring pre-storm-season walkthrough.
Why This Matters Beyond Appearance
Failed caulking creates entry points for wind-driven rain during spring storms, along with potential pest entry. Catching and addressing failed caulk early is far less costly than dealing with water intrusion damage after a storm.
