Plaster repair professionals near you

When looking for a plaster repair pro, make sure you complete the following steps:

• Verify their license and insurance: Plastering contractors may need a specific license, or the work might fall under a general contracting or painting license. Requirements vary by region. A pro should always have general liability insurance to protect your home.

• Get several bids: A proper estimate should include a detailed breakdown of labor, materials, the scope of work (including prep and cleanup), and a project timeline.

• Read their reviews: Look for mentions of clean work, good communication, and seamless texture matching. Red flags include complaints about messy job sites, poor blending, or unexpected costs.

• Look at their portfolios: Check their before-and-after photos. Pay close attention to how well the repair blends with the surrounding wall — a great repair should be nearly invisible.

• Find out if they have warranties: Ask if they offer a workmanship guarantee to protect you if the patch cracks or fails within a certain period after the job is done.

• Ask important questions: Good questions to ask include: "How will you contain dust during the project?," "What is your process for matching my existing wall texture?," and "Does your quote include cleanup?"

There are several factors that might impact the cost of this project, including:

• The size and scope of the damage: Repairing a few small cracks will naturally cost less than fixing a large hole or an entire crumbling wall. The more extensive the damage, the more labor and materials are needed.

• The type of plaster system: Traditional lath and plaster walls are more labor intensive and can be more expensive to repair than modern drywall systems that have a plaster finish.

• Where the damage is located: Ceiling repairs often cost more than wall repairs. Hard-to-reach areas, like high walls or stairwells, can also increase labor costs.

• Finishing and texture matching: Matching the surrounding wall texture requires extra time and skill, which can add to the final price.

• Any underlying issues: The cost may increase if the plaster damage is caused by a bigger problem, such as a leak or foundation issues, which needs to be addressed first.

Professionals repair damaged plaster by assessing the extent of the damage and stabilizing the area. They carefully remove loose or crumbling plaster and clean and secure the underlying lath if needed. For small cracks or holes, pros apply bonding agents and multiple layers of plaster or joint compound, allowing each layer to dry before smoothing. Larger or deeper damage may require patching with mesh or replacing sections of plaster. Once repaired, the surface is sanded smooth and primed, leaving it ready for painting and blending seamlessly with surrounding walls.

For small cracks and holes, a pre-mixed spackling or plaster patch compound is your best bet. For larger repairs, you’ll want to use a setting-type joint compound, which comes as a powder you mix with water. This often creates a stronger, more durable patch that's less likely to shrink or crack as it dries.

Common signs it’s time to repair your plaster include:

• Cracks. Look for fine hairline cracks or larger, more obvious fissures. While small cracks can be cosmetic, growing cracks may point to a deeper structural issue.

• Bulging or sagging. If your plaster is pulling away from the wall or ceiling, it means it has detached from the lath behind it. This should be addressed before a section collapses.

• Water damage. Yellow or brown stains, peeling paint, and damp spots are all signs of moisture. After you’ve fixed the leak, the damaged plaster will need to be repaired.

• Crumbling or flaking. Plaster that feels soft, powdery, or crumbles to the touch is deteriorating, often due to age or long-term moisture exposure.

• Holes and chips. Dents and gouges from impacts or accidents are common. Patching these up can restore the wall’s smooth, finished appearance.

To bond new plaster to old, you'll first need to clean the existing surface, remove any loose material, and apply a bonding agent. This creates a tacky, adhesive layer that helps the new plaster stick securely. Make sure you clean and dust the old plaster to remove any debris. Experienced pros usually know how to ensure a strong bond and a seamless finish.

Your plaster typically needs very little direct maintenance once it has fully cured. The key is to prioritize preventing new damage by controlling indoor humidity and watching for any new, significant cracks. Small hairline cracks can be easily patched, but larger ones may signal underlying structural issues that need attention.
