An exterior door gap in Arizona isn't just a comfort problem — it's a money problem. A 1/4" gap under your front door lets in enough hot air to add $15-$30/month to your summer cooling bill. Indeed, it also lets in dust, scorpions, and crickets. Here's how to diagnose where the gap is and fix it properly.
Diagnose the Gap
Close the door, turn off interior lights, and have someone shine a flashlight around the door perimeter from outside. Where you see light, you have a gap. The location tells you which fix you need:
Bottom Gap (Most Common)
Cause: The door sweep is worn, missing, or the threshold has shifted. Arizona's concrete slabs expand and contract with temperature — a threshold that was flush in winter can drop 1/8" by August.
Fix:
- Replace the door sweep ($18-$25 part, $45 labor). Moreover, we use the U-shape slide-on type for metal doors and the screw-on type for wood/fiberglass. The sweep should brush the threshold, not drag on it — dragging wears it out in months.
- Adjust the threshold. Typically, most modern thresholds have adjustment screws on top. Raising the threshold 1-2 turns closes the gap without touching the door. $35 if done with the sweep replacement.
Side Gaps
Cause: Weatherstripping is compressed, torn, or peeled away from the door stop. Arizona heat accelerates foam and rubber degradation.
Fix: Replace the weatherstripping strip. Moreover, we use kerf-style (press-fit into the door stop groove) or adhesive-backed V-strip depending on the door frame type. $35 per side, $65 for all three sides (top + both sides). Takes 20 minutes.
Top Gap
Cause: The door has sagged, pulling the top away from the head jamb. Usually caused by a worn top hinge.
Fix: Tighten or replace the top hinge. Naturally, if the screws spin (stripped hole), drive a 3" screw through the hinge into the wall stud behind the jamb. Indeed, this pulls the jamb tight and lifts the door back into alignment. $35. Of course, if the door is severely warped, the door itself needs replacement.
Arizona-Specific: Thermal Expansion
Your front door is a different size at 7 AM (72°F) vs. 3 PM (115°F). Metal doors expand up to 1/16" in length. Wood doors absorb morning humidity and swell, then shrink in afternoon dry heat. In fact, this is why a door that closes perfectly in the morning sticks in the afternoon — or vice versa.
The fix: Set your weatherstripping tension for the worst-case gap (usually the cooler morning state). For example, a slightly snug fit in the afternoon heat is better than a gap in the morning that lets AC escape all night.
