"Glen has been my go-to plaster repair expert for more than 15 years. His work is always top quality. I have seen him fix drywall in very tricky locations on small and extensive projects. He is reliable, punctual and reasonably priced. I recommend him without reservation."

"Did a great job plastering the exterior of my house. Covered the areas where a door had been removed and windows had been enlarged to perfection. All the work was very detail oriented and completed on time. Kept the area clean and neat as he completed each stage of the work. I would highly recommend Robert for any job large or small."

"Zohar at Best Builders Group came out to our house in order to check and see how and what to change in the existing kitchen. Zohar and his team of people did a wonderful remodeling job from A to Z. We were very impressed and surprised from the high quality of the work and from the professionalism of the workers. During the work, several issues came up during the remodeling project but the team and Zohar handled all of them with no effect to the completion date and with no additional cost. We are looking forward to hire them soon and to remodel all of our bathrooms."

Plaster Repair FAQs, answered by experts

Common causes of ceiling cracks along drywall seams include poor drywall installation techniques, structural issues, truss uplift, and foundation problems. Temperature and humidity also play major roles in ceiling cracks flush with the wall. As the drywall shrinks and expands from major temperature changes or extreme humidity shifts, this can cause the drywall to crack.

Plaster ceilings can sag for several reasons. In some cases, the plaster and other building materials shift and come apart over time, which is why you’ll commonly find drooping plaster ceilings in older homes. Improper installation, foot traffic, and water damage—often from a leaky roof or a broken pipe—can also cause plaster ceilings to sag.

Whether you can install or repair plaster yourself depends on the project's size and your comfort level with DIY projects. It's possible to handle small repairs on your own, but for larger projects like a room restoration or a full installation, it's often best to hire a local plaster professional. The final appearance, even coverage, and durability of the plaster depend heavily on proper wall preparation and application. If you are not 100% confident in your ability to achieve a professional result, letting an expert handle the job is a worthwhile investment.

Yes, you can use drywall repair techniques for some types of plaster damage. Tiny holes and small cracks in plaster can be patched in similar ways to drywall. You apply the necessary compound to fill the hole, wait for it to dry, then sand it down. For larger damage, like water damage or mold, you need to use plaster-specific techniques and materials.

Both plaster and drywall are durable wall finishes, but they differ significantly in installation, cost, performance, and aesthetics.

Installation & Cost: Drywall installation is faster and more affordable, typically costing $1.50 to $3 per square foot. It uses premade sheets, making it a more accessible DIY project. Plastering is a labor-intensive craft that requires specialized skills, pushing costs to $2 to $10 per square foot. It involves applying a wet paste over a lath framework.

Durability & Performance: Plaster is generally more durable, longer-lasting, and provides superior soundproofing. It is also a better insulator, which can help reduce energy costs. Drywall is easier to remove for future renovations.

Aesthetics: Drywall provides a smooth, uniform surface ready for paint or texture. Plaster offers a high-end, naturally textured look that can hide imperfections and is often preferred for achieving a classic or historic aesthetic.

Which is better? The choice depends on your priorities. Drywall is ideal for those prioritizing a lower upfront cost, faster installation, and DIY potential. Plaster is the better option for a higher-end project where durability, soundproofing, and a unique, premium finish are more important than the initial cost.
