Work out how many drywall sheets a room needs and what professional hanging and finishing typically costs in Florida.
Project Costs
What drywall costs in Florida per square foot to hang and finish, plus Level 5, fire-rated board, water damage repairs and worked examples for common rooms.
Drywall is part of nearly every Florida remodel, from bathroom and kitchen projects to garage conversions, additions and repairs after a leak or storm. This guide covers new drywall and the repairs homeowners ask about most.
| Item | Estimated range | What affects it |
|---|---|---|
| Walls, standard finish | $1.50–$3.50per sq. ft. of board | Ready for primer and paint. Most residential walls are finished to Level 4. |
| Ceilings, standard finish | $2–$4per sq. ft. of board | Overhead work is slower. High ceilings and textured finishes cost more. |
| Level 5 (skim coat) upgrade | $0.80–$1.80per sq. ft. of board | For strong side lighting, glossy paint or very smooth walls. |
| Type X fire-rated board upgrade | $0.40–$0.80per sq. ft. of board | Heavier 5/8 in. board used in fire-rated assemblies such as the wall between a house and an attached garage. |
Prices are per square foot of board installed, not floor area. A room's walls and ceiling together usually have three to four times as much board as the floor area.
| Item | Estimated range | What affects it |
|---|---|---|
| Small repair (holes, cracks, a few patches) | $60–$200per repair | Many contractors have a minimum charge, so group small repairs into one visit. |
| Ceiling patch (up to about 4 sq. ft.) | $150–$650per patch | Matching popcorn or knockdown texture adds time. |
| Water-damaged section of wall or ceiling | $400–$1,500per area | Fix the leak first. Mold remediation, if needed, is a separate cost. |
These examples use our drywall calculator.
| Project | What's included | Estimated range |
|---|---|---|
| Standard bedroom | 12 × 14 ft, 8 ft walls, one door and one window, ceiling | $900–$2,000 |
| Same room, Level 5 finish | Skim coat over walls and ceiling | $1,300–$3,000 |
| Large living room | 20 × 24 ft, 9 ft walls, two doors, four windows, ceiling | $2,000–$4,300 |
| Garage wall, fire-rated | 20 × 9 ft wall in Type X board | $350–$750 |

In Florida, drywall repairs often follow a leak, a roof problem or a flood. Fix the cause first, dry the area and check for mold before closing up. Larger mold problems may call for a licensed mold assessor and remediator. If your home is older, have popcorn ceilings and old joint compound tested for asbestos before sanding or removing them; our guide to preparing your house for a renovation explains why.
After a flood, check whether your home is in a flood zone. Repair costs can count toward the FEMA 50% rule, which can trigger much bigger requirements; see the 50% rule in Florida. For budgeting the unknowns, read change orders and hidden damage.
Add up the wall area (perimeter times wall height), subtract doors and windows, and add the ceiling. Then add about 10% for waste. Our drywall calculator does this for you and counts sheets.
It's a thin skim coat of compound over the whole surface after normal taping and finishing. It hides joints under strong side lighting or glossy paint. Most walls are finished to Level 4.
Patching drywall usually doesn't need one. Replacing large areas, especially after flooding, may need a permit, and in flood zones repair costs can count toward the FEMA 50% rule. Check with your building department.
Wet drywall and insulation are usually removed above the waterline so the wall cavity can dry and be checked for mold. Follow guidance from your insurer and a qualified mitigation company.
