# ''For a lasting threshold replacement, follow these pro techniques honed in extreme climates:''
+
## ***Precision Removal***
+
*** Cut old fasteners with an oscillating tool (use a carbide grit blade for rusted nails)
+
*** Preserve the sub-sill by prying upward, not outward
+
## ***Material Science***
+
*** Aluminum thresholds need thermal breaks to prevent condensation
+
*** Solid wood requires end-grain sealing with epoxy before installation
+
## ***Weatherproof Installation***
+
*** Achieve a 7° downward slope (verify with a digital angle finder)
+
*** Shim every 12" to prevent deflection under load
+
*** Seal with elastomeric urethane (3M 5200 or equivalent)
+
# ***Critical Tip:*** Test drainage before final sealing—pour water across the threshold and verify it exits completely within 10 seconds. Any pooling indicates improper slope.nal sealing.
