OnAim Conservation, LLC. is an art conservation company located in Houston, Texas, for small to large scale outdoor sculpture needs. Our conservation efforts help to develop and implement a customized program for the upkeep of public and private art collections. If necessary, we can assess damage and offer treatment needed to restore the artwork to its original state. We can also arrange and oversee the safe transportation and installation of outdoor works. We are fully insured with a general commercial liability plus a fine art conservators policy that covers sculptures on site, while in transit and at our premises.


Preventive conservation ensures the sculpture’s longevity and prevents the need for costly and time-consuming restoration. Especially for outdoor sculptures, much of the prevention efforts are focused on combating environmental pollutants, such as acid rain. We help you develop and implement a customized routine treatment program for your collection.

OnAim Conservation LLC is a certified woman-owned business and a member of the American Institute of Conservation.
