Conservators also go on-site to perform hands-on work when necessary. Many institutions require the services of an outside team. In an historic house where staff is limited, almost all conservation is outsourced to professionals. When objects require in-situ attention, the conservator will bring her tools and expertise on-site. Emergency disaster recovery of textiles, installation and de-installation of large, or unwieldy textiles such as tapestries, mounted quilts or modern wall-hangings, or repair of bedhangings, drapery or wall-coverings may all be occasion for on-site work. This kind of work is typically contracted at at a flat-fee rate per day, which is multiplied per conservator. All travel costs and material costs are additional.
