"I am totally disappointed with this Company. They were like a different company, from our first encounter with them, making false promises to show up at certain times and then not showing up. Only doing a fair job on the stain where I had to go around and touch up in numerous areas even after they came back to do touch ups and don?t get me started on their lack of prompt communication. Communication back from the owner only happened when I got frustrated enough to get real with my emails and say how I was feeling. It was like pulling teeth to get this project done but it would have gone more smoothly had they started when they initially said they would until they got a bigger job that was more important. We are hiring a new company to re stain our deck. "

Plaster Repair questions, answered by experts

Plastering comes at a higher cost than installing drywall, but it also provides some pretty enticing benefits. First, plaster usually lasts longer than drywall, so long-term costs will usually be lower. Second, plaster is a highly insulative material, so it might help make your living area feel more comfortable and keep your heating and cooling costs lower, especially in the summer and winter. Finally, plastering is naturally textured, so it helps hide imperfections and often adds warmth to your home that drywall won’t.

Painting or plastering over water-damaged wall plaster is only a temporary fix and doesn’t fix the real problem. If you must, wait until the surface is completely dry before applying a new layer. However, we recommend you remove the damaged plaster and properly perform a repair or hire a professional to do it. Water damage repair is normally covered by your home insurance.

Applying plaster to a wall will usually cost between $2 and $10 per square foot for both the material and labor. The cost will vary based on the quality of the plaster you’re using and whether or not prep work is required before the work begins. Wall prep can add up to about 10% to your total costs. Plastering exterior walls can be more expensive in many cases because they are taller and require scaffolding and safety equipment.

You can apply plaster over plaster, but before you do, check the stability of the existing plaster. If it’s been there for a while, it may require a base coat of PVA emulsion. This will make the existing plaster less porous and ensure the new and old plaster adhere properly.

Small hairline cracks in plaster walls are not serious and are mostly cosmetic, but larger or widespread cracks indicate structural problems that need repair. 

  • Cracks 0.5 cm (0.2 inches) or thinner: Cosmetic cracks you can repair if desired.

  • Cracks wider than 0.5 centimeters or widespread cracks: Structural repair is needed, either DIY or by a pro.

  • Cracks 2.5 centimeters (1 inch) or wider: Contact a plaster repair professional.

Watch for large, deep cracks, multiple cracks in the same area, and cracks along the walls where they meet the ceiling. Repair these cracks to prevent further damage.
