Framing and Drywall in Georgia
Interior walls built from the studs out: framing, board, taping and finishing, plus patching of older plaster.
Framing is the skeleton of an interior wall. Drywall is the board that covers it, and finishing is the taping, coating and sanding that makes the surface ready for paint. Jermaine Enterprises, based on Greenbriar Parkway SW in Atlanta, quotes framing, boarding and finishing as one scope, so a wall is priced from open studs to a paint-ready surface.
Typical projects include layout changes, basement finishing, small commercial partitions and unit turnovers. Each needs a wall that is straight, tight and specified to the rating the building requires.
Framing: where a wall starts
A wall is laid out on the floor before a single stud goes up: where the doors open, where cabinets will hang and where the wall must line up with the structure above. Studs, plates, headers over openings and blocking behind anything heavy are set to that layout. In the reference assembly that the Gypsum Association uses to define a one-hour wall, the studs are 2x4 wood members spaced 16 inches on center, the spacing used in that tested assembly.
Framing is also where many later problems are avoided. A plumb frame gives the board a flat face to fasten to, and blocking set at layout gives cabinets and grab bars solid backing.
Drywall: board types and fire ratings
Not all drywall is the same product. Type X gypsum board is defined in ASTM C1396 as a fire-resistive panel. A five-eighths inch Type X panel reaches at least a one-hour rating in the reference wood-stud wall when it is installed on both sides, fastened with 6d coated nails 1-7/8 inches long at 7 inches on center, with the joints staggered 16 inches. That assembly is tested under ASTM E119.
Type C board is a proprietary version of Type X with an enhanced core. A five-eighths inch Type C panel can be used wherever a system calls for five-eighths inch Type X, but Type X cannot stand in where a system requires Type C without risking the rating. The Gypsum Association's GA-600 manual lists tested wall systems that depend on the exact combination of panel thickness, fasteners, studs and joint treatment, so substituting materials or changing the layout can void an assembly's rating. For a rated wall, the plan names the assembly and the work follows it.
Finishing: joint compound and levels of finish
Finishing is done in coats. Taping compound embeds the paper tape and is the strongest bonding and hardest sanding compound. Topping compound, used for the second and third coats, shrinks the least and sands the easiest. All-purpose compound can serve for both, and setting-type compounds, which cure by chemical reaction, are used where speed or a hard patch is needed.
How many coats a wall gets depends on the finish level specified under GA-214. Level 4 is typically specified where smooth walls will get flat paint, light textures or wallcoverings. Level 5 adds a skim coat and is typically specified for glossy or sheen paints, dark deep-tone paints and walls under strong side lighting, where a lighter finish would show joints as faint ridges, an effect called joint photographing. Choosing the level before finishing starts means the wall can be finished once, for the sheen and lighting it will have.
Sound control starts with sealing
A wall can look identical and sound very different. USG's published data shows that a partition with one five-eighths inch panel on each side and a 1-1/2 inch sound attenuation blanket reaches STC 53 when acoustical sealant is applied where the board meets the floor and the runner, and only STC 29 without it. For a wall that needs to be quiet, such as between a bedroom and a living room or between two offices, the cavity insulation, the sealant at the perimeter and sometimes resilient channels or a second layer of board each add to the result. The Gypsum Association lists a generic one-hour, STC 50 to 54 wood-stud wall that combines resilient channels, two layers of Type X board and three inches of mineral or glass fiber insulation.
Plaster repair on older walls
Older buildings can have plaster walls. Small surface cracks in veneer plaster can be filled with veneer basecoat plaster, and setting-type joint compound is listed for patching plaster surfaces. Whether a wall can be patched or should be replaced depends on how much of it has lost its bond to the lath, which is judged on site before a price is given.

How a job like this runs
Describe the wall
You send the address and what the wall must do: divide a room, hold a door, block sound or meet a fire rating.
Scope and price in writing
The framing, board type, finish level and any rated assembly are written into the scope before work starts.
Build and board
The frame is set to the layout, the board is hung to the specified fastening pattern and inspections are scheduled where the permit requires them.
Finish and walk through
Joints are taped, coated and sanded to the agreed finish level, and the wall is checked in side light before it is handed over for paint.
Permits and codes in Georgia
Some interior framing jobs need a permit, depending on the city, and a rated wall is checked against its listed assembly. Georgia's state minimum building codes are adopted by the Department of Community Affairs and enforced by each city. DCA's own announcement and several city notices give different effective dates for the 2024 code editions, so confirm which edition applies to your address with the local building department before work starts.
Questions about framing and drywall
What is the difference between Type X and regular drywall?
Type X is gypsum board with special core additives defined in ASTM C1396 to give better fire resistance. A 5/8 inch Type X panel is defined as reaching at least a one-hour rating in the reference wood-stud assembly. Regular board does not carry that definition, so rated walls and ceilings call for the specific board named in the tested assembly.
What drywall finish level do I need under dark or glossy paint?
GA-214 says Level 5 is typically specified where non-flat paints, dark deep-tone paints or critical lighting are involved, because it minimizes joint photographing. Level 4 suits flat paints and light textures.
Can a fire-rated wall be built with any 5/8 inch board?
Not necessarily. Rated systems are tested with specific materials, fastener spacing and joint layouts, and the Gypsum Association notes that substitutions can invalidate an assembly's rating. Where a design calls for Type C, Type X should not be substituted.
How do you make an interior wall quieter?
Sound control comes from the whole assembly: insulation in the cavity, resilient channels or heavier layers, and sealed perimeters. USG data shows acoustical sealant alone can be the difference between STC 53 and STC 29 on the same wall.
Can old plaster walls be patched instead of replaced?
Often, yes. USG's plaster guidance describes filling small surface cracks in veneer plaster with basecoat plaster, and setting-type joint compound is listed for patching plaster surfaces. The right repair depends on whether the plaster is still bonded to its base.
Verify before you hire anyone. Check any contractor's state license on the Secretary of State contractor board and your city's permit requirements before work starts.
