St. Louis' Leading Commercial Plastering & Historic Restoration Specialists

Acoustical plaster is highly porous, meaning unsealed drywall joints underneath act like a vacuum—drawing in drafts that trap dust and leave permanent dark streaks across your ceiling. We prevent this by managing the entire framing and drywall assembly ourselves, taping and air-sealing the substrate to eliminate airflow before spraying the plaster. This single-source accountability protects the acoustic rating, keeps the finish bright, and fully secures your manufacturer's warranty.

Demolishing old plaster is incredibly messy and expensive. If the underlying wood lath is still structurally sound, the plaster should be saved rather than replaced. Our master mechanics use specialized adhesives and structural mesh to bond sagging plaster back to its original lath. This stabilization technique saves you thousands of dollars in demolition and disposal costs while keeping the project fully compliant with local historic preservation boards.

Modern off-the-shelf plaster behaves differently from historical materials, and using the wrong mix can cause chemical reactions that lead to cracking. We analyze whether your original walls used a traditional non-hydraulic lime mix or a later 19th-century gypsum mix. We then formulate custom batches that match the original sand, lime, or gypsum ratios of your specific building, ensuring our patchwork blends seamlessly and lasts for decades.

Heavy-duty Portland cement and veneer plasters are highly sensitive to building movement and rapid drying, which are the main causes of hairline cracks. We prevent this by engineering proper control joint spacing and applying fiberglass mesh reinforcement at critical stress points, like the corners of doors and windows. This keeps your high-traffic hallways and walls perfectly smooth and free from impact damage.
