Exterior Door & Weatherstripping repair in Orlando, FL

Verified against official sources · Updated 2026-07-06

Thinking about an exterior door & weatherstripping repair in the Orlando area? Here's what actually matters — permit rules for Orange County and the City of Orlando, plus the mistakes and code requirements that trip up homeowners, sourced from manufacturer manuals and the Florida Building Code.

Do you need a permit?

Permit required. Permit required; product must carry a Florida Product Approval number rated for the site's design pressure, with the Product Approval sheet filed and install instructions on site at inspection.

Key facts before you start

Bottom-of-door draft: don't plane the door or shim hinges first — most entry doors have an adjustable sill cap; turn the screws in the cap to raise it until a dollar bill barely pulls out between door bottom and sill without tearing (test at each screw), then re-trim the jamb weatherstrip to fit the new sill height (Therma-Tru spec).
Jamb weatherstrip on modern pre-hung doors is kerf-in: no fasteners or adhesive — pull the old strip out of the groove starting at the top, press the new strip's flat fin into the jamb kerf, cut to length with scissors. Match kerf-in like-for-like; screw-on surface-mount (aluminum carrier + vinyl bulb) is only for jambs with no kerf.
Drafts/water at a bottom CORNER of the door are usually the missing/flattened corner seal pads (small adhesive pads bridging sill cap, door-bottom sweep, and weatherstrip), not the sweep — a ~$5 part; Therma-Tru's fix sequence is remove corner pad, pull weatherstrip at bottom, replace pads.
Door sweep: cut to door width with scissors (vinyl) or hacksaw (aluminum carrier), install from the interior with the door CLOSED so the fin seals against the threshold before marking screw holes; a standard residential sweep only seals gaps up to 1/2" — bigger gaps need the threshold raised, not a taller sweep (M-D Building Products).
Orlando/Orange County FL: weatherstrip, sweep, corner-pad, and threshold-cap work is repair/maintenance — but REPLACING an exterior door, even size-for-size, requires a residential permit filed as 'Windows\Doors Replacement size for size' with the Orange County Product Approval Specification Sheet (FL Product Approval = wind rating), and the approved installation details must be on the jobsite at inspection or it fails.
Deadbolt/smart-lock swap (e.g., Kwikset SmartCode): standard prep is a 2-1/8" (54mm) cross bore; measure backset (door edge to bore center) before buying — it's 2-3/8" or 2-3/4" (60/70mm), and adjustable latches switch between the two via the slide/pin, so no re-boring.
