Drywall in everyday language
Drywall is made in panels with a gypsum core. The panels are attached to a supporting structure, and their joints are finished before the wall is decorated. You may also hear people say wallboard or sheetrock when talking about this type of wall.
Plaster is a different system
Traditional plaster is built up over a supporting base rather than installed as a ready-made panel surface. Older houses may have plaster, drywall, or a mixture of materials from past renovations. The age of a house is a clue, not a definitive way to identify every wall.
Why a repair starts with identification
A repair that suits a damaged drywall panel is not automatically right for a loose or cracked plaster surface. The condition of the material and how it is supported matter. Tell Josh if you know the wall type, but it is fine to say you are unsure.
Useful clues without opening the wall
Share any information from previous renovation work, an inspection report, or an already exposed edge. Photograph the damage and the surrounding room. Do not make a new opening just to identify the material. It may be more useful to have the wall assessed in person.
Match the repair to the project
Ask what material is present, what needs repair, and what result can reasonably be expected. If you have older textured surfaces or materials you do not recognize, discuss them before sanding or disturbing them. Confirm which work Josh can take on after reviewing the wall rather than assuming every surface is the same.
Can Josh tell the wall type from a photo?
A photo may help, but it does not always show the wall system or its condition. An in-person assessment may be needed.
General homeowner information. The right approach depends on the material, condition, and scope of your project. Discuss the details with Josh before deciding on the work.
