Building movement, the elements, construction variables and age effect the overall damage of a structure. Brick façades develop cracks, spalls, and structural deficiencies over time due to ever-changing atmospheric conditions.
The Culbertson Restoration team investigates all potential conditions before recommending corrective procedures. It is imperative to understand the fundamental causes of brick deterioration to ensure the correct professional restoration / repair practices.
Both new and old brick façades often leak due to defective shelf angle, mortar joints and window head flashing. Culbertson Restoration has perfected the installation of new shelf angle or lintel flashing with minimal client disruption and maximum effectiveness.
Shelf angle corrosion and exfoliation cause brick spalls and cracking. Shelf angle, lintel removal and replacement may need to be incorporated with flashing repairs.
We ensure all repair procedures are specified and performed effectively and economically to the owner’s satisfaction.
Terra Cotta Restoration
In the United States between 1880 and 1930, terra cotta (baked clay) was an inexpensive and architecturally pleasing cladding alternative to stone masonry. The exterior glazed finish replicated stone and came in a variety of colors.
Restoring and repairing terra cotta façades today is a costly, time consuming and complex procedure. Terra cotta failures include glaze crazings and spalling, stress cracking, metal anchor corroding and backfill erosion. These failures are often related to water penetration, building movement and manufacturing defects.
Since the 1980s, Culbertson Restoration has been restoring these façades. Oftentimes, replacing terra cotta is costly and it may take up to a year to manufacture replacement units. We understand that many situations will not allow for the long lead-time, and sometimes, budgets are tight. Suitable substitute materials include stone, fiberglass, fiber-reinforced concrete or pre-cast. Each of these materials have their pros and cons.
Stabilizing a terra cotta façade involves repointing, glaze spall repair, minor fabric spalling, replacement and structural repairs. Culbertson Restoration works with renowned terra cotta experts and manufacturers to assist building owners with making the most cost-effective and lasting investment.
Mother Nature, pollution, acid rain and time contribute to the degradation of stone structures, whether limestone, brownstone, marble or granite.
Culbertson Restoration’s team of professionals and craftsmen are experienced in all facets of stone repair, restoration and preservation, including patching and crack stitching, Dutchmen repairs (replacing damaged stone with new stone), retooling and fabricating new stone units.
Culbertson Restoration works with quality stone fabricators within the United States, Canada and Italy to reproduce any detail required to match existing stonework.
