<br /> <br />Wrought iron window grates are visible in the 1979 Survey Card photo. It is not known how old the <br />existing fixtures are, if they are original to the house, or if these are the same wrought iron gates from the <br />1979 Survey Card. The current gates are only present on the street facing windows and have scroll -work <br />detailing in the centers. <br /> <br />Were the applicant not changing the size of the windows (necessitating new siding material), staff would <br />administratively approve the replacement of the vinyl windows with new vinyl windows. <br /> <br />STANDARDS AND GUIDELINES: CHAPIN PARK <br />II. EXISTING STRUCTURES <br />A. BUILDING MATERIALS <br />Original exterior building materials in the district include brick , stucco, clapboard, wood shingles, and <br />brick or stone masonry. In some instances, vinyl, composite and aluminum siding have been applied <br />over the original material. <br />Required <br />Original exterior building materials shall be retained when possible. Deterioration of wood materials <br />shall be prevented through repair, cleaning and painting. The existing architectural detail around <br />windows, porches, doors and eaves shall be retained or replaced by replicas of the same design when <br />deteriorated be yond repair. <br />Masonry, including brick and stucco structures, shall be maintained, and properly cleaned only when <br />necessary to halt deterioration or to remove stains and shall be done in a method acceptable for the <br />preservation of the surface: i.e. low-pressure water and soft natural bristle brushes. Brick or masonry <br />mortar joints should be repainted only when there is evidence of moisture problems, or when sufficient <br />mortar is missing to allow water to stand in the mortar joint. Existing mortar shall be duplicated in <br />composition, color, texture, joint size, method of application and joint profile. <br />When repairing stucco, stucco mixture shall be used. A professional shall make a study of the old stucco, <br />to determine the exact mixture and underlayment used in the original work. Some repair methods are not <br />compatible with the original techniques and may cause early disintegration of the repair work and the <br />original work. <br />Ample ventilation must be afforded the structure when siding is installed, in order to prevent increased <br />deterioration of the structure from moisture and insects. <br />Recommended <br />Whenever possible, the o riginal building materials should be restored. When maintaining or <br />repairing original siding is not feasible, aluminum, vinyl or composite siding may be used. When <br />used over wood surfaces, this siding should be the same size and style as the original wood. Every <br />effort should be made to retain the original trim around windows, doors, cornices gables, eaves <br />and other architectural features. <br />Property owners should contact the Historic Preservation Commission of South Bend and St. Joseph <br />County prior to initiating any restoration or rehabilitation effort. [ Address and contact information is <br />listed in the front of the Guidebook.] The Commission is an invaluable source of information about all <br />facets of rehabilitation and restoration - materials, methods, contractors and the like. <br />Prohibited <br />Wood siding shall not be resurfaced with new materials that is inappropriate or was unavailable when the <br />building was constructed, such as artificial stone, brick veneer, asbestos or asphalt shing les. <br />Sandblasting or the use of harsh detergents shall not be used on masonry including brick, stucco, <br />limestone, flagstone and sandstone. This method of cleaning erodes the surface material and accelerates <br />deterioration. <br />Repainting shall not be done with a mortar of high Portland cement content which can often create a <br />bond that is stronger than the building material. Usage of Portland cement can cause deterioration as a <br />result of the differing coefficient of expansion and porosity of the historic masonry unit and the mortar. <br />This most often results in serious damage to adjacent brick. <br />Unpainted masonry surfaces shall not be painted unless they had been painted originally. Paint shall <br />not be removed from masonry surfaces by any means that damage the surface. <br />Not Recommended <br />Waterproof or water repellant coatings or surface consolidation treatments should not be used on masonry <br />surfaces unless required to solve a specific problem that has been studied and identified.
