Geometric column repair restores and stabilizes the molded profiles and decorative geometry on the exterior columns of historic buildings. Our process begins with a careful assessment of material loss, cracking, and previous repairs to determine whether masonry, cast stone, wood, or composite elements are original. We match original profiles and tooling by documenting existing geometry, creating measured templates, and using compatible repair materials that replicate the original texture, color, and compressive strength. Repairs range from minimal grout and epoxy injections for hairline cracks to partial spall patching, replacement inserts, or sculpted overlays for lost moldings and cap details. Work is performed to preserve as much original fabric as possible, hide transitions with period-accurate joint lines, and ensure weather-tightness and long-term durability. The result is a faithful restoration of the column’s geometric rhythm and architectural intent, maintaining visual continuity with the building’s historic character while meeting modern performance expectations.

Old historical window undergoing professional repair and sealing. Visible are water-stained wood, peeling paint, and degraded glazing putty along the sash. Conservator’s hands, wearing nitrile gloves, are carefully removing loose rot and old putty with precision tools. New wood consolidant has been applied to stabilize softened areas, and a matching replacement muntin is being fitted where decay required splicing. Fresh, historically accurate glazing compound is smoothed into the panes, and a clear penetrating sealer is being brushed onto the repaired wood to protect against future moisture intrusion. The surrounding frame shows evidence of reclaimed finish to match original patina, and work is staged on a drop cloth to capture debris. The repair balances preservation of original fabric with necessary replacement for structural stability and long-term weather resistance.

Before: decades of neglect left historical crown molding cracked, missing sections, and layered with paint that obscured original detail.

After: careful documentation, reverse paint removal, and hand-sculpted infills restored profiles and ornamentation to match the original craftsmanship. Stabilized substrates and historically appropriate adhesives ensure longevity while selective patination and finish work reintegrate the molding visually with the surrounding architecture. The result is a seamless restoration that preserves historic character while meeting modern conservation standards.
