Garage & Lanai Drywall: The Questions Homeowners Ask Most

Garage drywall cost starts from $1200 per garage, and the final figure moves with the size of the garage, the ceiling height, whether the ceiling is already boarded, and whether the walls need texture to match the house. That is the short version. The rest of this page is the dozen questions that come up on almost every quote, answered the way we would answer them at your garage door.

How much does garage drywall cost, and what moves the price?

The $1200 starting figure is for a garage that needs boarding, taping and a simple finish. Four things push it up or down:

We would rather send you a firm number than a range that widens at the door. Text us photos of the garage and we will price it from those. For how repair pricing works on the rest of the house, see How Much Does Drywall Repair Cost in Central Florida? (2026 Prices).

Is it worth finishing a garage at all?

For a garage you actually use, usually yes, and it is one of the cheaper upgrades available. Bare studs and open framing let dust sift into everything you store. They also let the heat of a Central Florida afternoon radiate straight through into the space where you work. And there is nothing solid to screw a shelf bracket into except the studs themselves.

If the garage is only ever somewhere to park, and you do not mind the look, you do not have to finish the walls that do not touch the house. The wall shared with the house and the ceiling under living space are different, and that is the next question.

Does the house wall and ceiling need special board?

Generally, yes. The wall between a garage and the house, and a ceiling that sits under living space, are fire separation assemblies. That normally means 5/8-inch type X board, and the joints have to be taped and finished, not just screwed up and left.

This is the point people miss. A garage with the right board but unfinished joints is not a finished fire separation. It tends to surface at resale, on an inspection report, at the worst possible moment. Exactly what your local building department requires can vary, so if you have any doubt, ask them. If you are still deciding whether to hire someone at all, ask any contractor how they handle fire-rated joints, dust and drying time before anyone starts.

Do I need to board the whole garage ceiling?

If living space sits above the garage, yes, that ceiling is part of the fire separation and needs to be boarded and finished. If the garage has open attic space above it with no rooms over it, the requirement can be different, and plenty of people board it anyway because a boarded garage ceiling cuts dust and looks far better. A garage ceiling is also where you notice every flaw, because overhead lights and a raking angle show every ridge. Good finishing matters more up there than on the walls.

How long does it take?

Most single garages finish in two to three days, including the drying time between coats of compound. Joint compound has to dry before the next coat goes on, and rushing that is how you get cracks and visible seams. Humid weather slows drying, so the same job in a wet August can take longer than in a dry January. Two-car or heavily framed garages take longer. For the general timing of drywall work, see How Long Does Drywall Repair Take?

What about enclosed lanais?

A lanai conversion is a different animal from a garage. You are taking a space that was built to be semi-outdoors and asking it to behave like a room, and the wall assembly sits in high humidity most of the year. Standard paper-faced board on an exterior-facing lanai wall is asking for trouble. We use moisture-resistant board where it belongs.

We will also tell you straight if we think a vapour problem is being built in rather than solved. If the wall behind the board has no sensible moisture control, new drywall just gives the moisture something to soak into. Sometimes the honest answer is that the wall needs sorting out first, by whoever did the enclosure, before any board goes up. A lanai enclosure drywall job done over a problem wall is money spent twice.

Can I use regular drywall in a garage?

On the walls that are not part of the house separation, standard board is normally fine, subject to local requirements. On the house wall and any ceiling under living space, use the fire-rated board above. Garages are not heated or cooled like a living room, so they swing in temperature and humidity, and a garage with a door that opens every day sees a lot of moisture. For a garage that floods or gets damp, we would talk through the options before quoting.

Do the walls need texture?

Not always. If the garage adjoins finished living space, such as a door through to a hallway or a wall that is visible from the house side, we match the texture. Matching knockdown and orange peel is the part most handymen skip, and the reason you can still see their patch a year later.

If the garage is purely a garage, we leave it clean and simple. That saves money and nobody parks a car and admires the wall finish. If you want it matched anyway, say so when you text.

What about dust? I have a house attached.

Garage drywall work throws a lot of fine dust, and an attached house means it will try to follow the door. On every interior job we run plastic, zip walls and a HEPA vac. That is not a bedsheet over the doorway. A garage job where nothing is sealed will leave dust in your hallway for weeks, so ask any contractor how they handle it before you book.

Can I do it myself?

You can, and a small garage is one of the more forgiving places to learn. The honest warning is that hanging the board is the easy part. Taping, three coats of compound and sanding to something flat is where first-timers struggle, and a garage ceiling is hard work overhead. On the fire-rated areas, a poorly finished joint can cause trouble later. We went through the common failures in Can You DIY Drywall Repair? Where It Goes Wrong. If you are comfortable with the work and the garage is purely a garage, go ahead. If the house wall is involved and you want it right, hire it out.

Do I need a permit?

It depends on the scope and on the building department where you live, and we would not want to guess for your address. Finishing the walls of an existing garage may not need one, but a lanai conversion or any change to the structure often does. A call to your local building department takes a few minutes and settles it. Whoever you hire should be willing to tell you what they think and where the question is open.

What should I do before you arrive?

Clear the walls. Move cars, bikes and shelving away from the perimeter, and take down anything hung on the studs. Give us a way to reach the ceiling, and keep pets and kids out of the work area. Clearing the room does most of the job.

What happens if the garage has storm or water damage?

Then the drywall is the second step, not the first. Anything wet needs to be dry and the source fixed before board goes on, or the new work fails. If the water has already stained a ceiling, a stained ceiling is worth taking seriously, and the source has to be found before any patch goes on.

How do I get a price?

Text us photos of the garage or lanai at (352) 561-3616. Send a wide shot of each wall, one of the ceiling, and one of any spot that looks damp or damaged. You get a price from the photos without booking a two-hour appointment window, and the quote is free. If a photo shows something that changes the plan, we will say so before you spend anything.
