What Door Installation Costs in Central Florida

Interior doors, exterior doors, prehung versus slab, and the Florida-specific requirements that change the number.

Door pricing confuses people because the door itself is often the smaller part of the cost. What determines the number is the type of installation, the condition of what is already there, and in Florida, whether the door has to meet wind-borne debris requirements.

Interior doors

The cheapest and most predictable category. Two approaches:

• Slab replacement — reusing the existing frame and hinges, hanging a new door leaf. Cheapest, and only works if the existing frame is square, sound and the hinge positions can be matched or re-mortised.
• Prehung replacement — new door and new frame as a unit. More expensive in materials and more work, because the trim comes off and goes back on, but it corrects a frame that is out of square and it is the more reliable result.

Most interior door problems people live with — doors that stick, will not latch, or swing open on their own — come from a frame that has moved rather than the door itself. Our guide to sticking doors covers the fixes that do not need a new door at all.

Exterior doors

Higher cost, more variables, and in Florida there are requirements that do not exist elsewhere.

• Material. Fiberglass is the sensible default in Central Florida — it does not warp, rot or rust and it handles our humidity far better than wood. Steel is durable and can corrode near the coast. Wood looks best and demands the most maintenance in this climate.
• Impact rating. Depending on your location and the current code requirements, an exterior door may need to meet wind-borne debris standards. Impact-rated units cost meaningfully more and are worth confirming before you shop. Our comparison of shutters versus impact glass covers the same trade-off on windows.
• Glass. Sidelights, transoms and decorative glass all add cost, and glass in an exterior door has its own impact requirements.
• Threshold and flashing. This is where exterior door installs succeed or fail. A door set without proper flashing and a correctly detailed threshold will leak, and in Florida rain it will leak a lot.

What makes an install cost more

• Changing the opening size. Any change to the rough opening means framing work, and on an exterior wall it may mean a new header. This moves the job into a different category entirely.
• Rot in the frame or subfloor. Common on exterior doors in Central Florida, and often not visible until the old unit comes out. We flag it as soon as we find it rather than after.
• Hardware. Lock sets, smart locks, closers and specialty hinges.
• Trim and finish. Matching existing casing, plus caulk, paint and touch-up.
• Disposal of the old unit.

Where the Florida climate matters

Doors here take a beating that they do not in a milder climate:

• Humidity swells wood doors and jambs seasonally, which is why a door can fit fine in January and stick in August.
• Sun on a west-facing door degrades finish quickly and can warp a wood slab. A storm door on a sun-exposed entry can actually make it worse by trapping heat.
• Driving rain finds any gap in the flashing or threshold detail.
• Wood rot at the bottom of jambs and at the threshold is one of the most common exterior door failures we see. Our article on wood rot in Central Florida homes covers prevention.

Getting an accurate number

Door quotes given over the phone are guesses, because the significant variables — frame condition, rot, squareness, whether the opening is standard — are only visible on site. A free estimate takes a few minutes and gives you a real figure.
