Plaster repair in Rochester

Plaster repair in Rochester is a specialized trade that addresses the unique aging characteristics of lath-and-plaster walls common in many of the city's historic homes and commercial buildings. Unlike drywall, traditional plaster is applied in multiple coats over wooden lath strips, creating a rigid, durable surface that can last over a century if maintained. However, Rochester's freeze-thaw cycles, high humidity from Lake Ontario, and settling of older foundations often cause common issues such as hairline cracks, bulging sections, key failures where plaster separates from lath, and water damage from leaky roofs or pipes. The repair process begins with a thorough inspection to identify loose or detached areas—a critical step because simply filling a crack without addressing underlying movement will lead to recurring damage. For small cracks, we use a two-step technique: widening the crack slightly to create a mechanical bond, applying a bonding agent, then filling with a specialized plaster compound that matches the original material's texture and strength. Larger repairs involve removing damaged plaster back to sound lath, installing new galvanized lath if needed, and applying three coats of plaster—scratch, brown, and finish—each allowed to cure properly to prevent future cracking. This methodical approach is essential for Rochester properties, where original plaster often contains horsehair or other organic fibers that require compatible repair materials to avoid differential expansion and contraction. We also match the final texture to the surrounding wall, whether it's a smooth trowel finish common in the 1920s or a more textured surface found in Victorian-era homes.

For Rochester homeowners, plaster repair is not merely aesthetic—it preserves the structural integrity of the wall assembly. Original plaster acts as a fire barrier and provides superior soundproofing compared to modern drywall. When we repair plaster, we are restoring the building's thermal mass, which helps regulate indoor humidity during Rochester's humid summers and dry winters. The process requires patience: each coat must dry thoroughly before the next is applied, which can take several days depending on the season. We also address the root causes of damage, such as redirecting gutter downspouts away from foundations or sealing window frames to prevent moisture infiltration. This holistic approach ensures that repairs last and that your Rochester property maintains its character and value.
