Metal Restoration


When a building’s exterior panels or frames start to weather, they lose their original luster. Weathering may cause oxidation, pits, and crevices. Metal restoration stops corrosion and renews the appearance of the facade.

Our team uses special cleaners and protective coatings to restore the shine to both anodized and natural aluminum. If needed, we can expertly hide permanent damage from the panels. We also work with stone masonry and the intricate surfaces of historical buildings.

We recommend regular maintenance to minimize any future metal restoration requirements. Look at our results.
