Recommended <br />Whenever possible, the original building materials should be restored. When maintaining or repairing original siding is not <br />• feasible, aluminum, vinyl or composite siding may be used. When used over wood surfaces, this siding should be the same size <br />and style as the original wood. Every effort should be made to retain the original trim around windows, doors, cornices gables, <br />eaves and other architectural features. <br />Property owners should contact the Historic Preservation Commission of South Bend and St. Joseph County prior to initiating <br />any restoration or rehabilitation effort. [ Address and contact information is listed in the front of the Guidebook.] The <br />Commission is an invaluable source of information about all facets of rehabilitation and restoration — materials, methods, <br />contractors and the like. <br />Prohibited <br />Wood siding shall not be resurfaced with new materials that is inappropriate or was unavailable when the building was <br />constructed, such as artificial stone, brick veneer, asbestos or asphalt shingles. <br />Sandblasting or the use of harsh detergents shall not be used on masonry including brick, stucco, limestone, flagstone and <br />sandstone. This method of cleaning erodes the surface material and accelerates deterioration. <br />Repointing shall not be done with a mortar of high Portland cement content which can often create a bond that is stronger than <br />the building material. Usage of Portland cement can cause deterioration as a result of the differing coefficient of expansion and <br />porosity of the historic masonry unit and the mortar. 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 not be removed from <br />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 surfaces unless <br />required to solve a specific problem that has been studied and identified. Coatings are frequently unnecessary and expensive, and <br />can accelerate deterioration of the masonry. Mortar joints, which do not need repointing, should not be repointed. Wood siding <br />should not be power -washed. <br />C. WINDOWS AND DOORS <br />Window and door frames are in most cases wood and vary depending upon the style of the home. Many are double -hung <br />windows with wood trim and sills. Brick structures have stone sills and brick lintels. In some cases where aluminum siding has <br />been applied, the window and door trim has been covered. About half of the structures in the district have aluminum storm <br />windows; the other half have wood storm windows. <br />Required <br />• Original windows and doors shall be retained including sashes, lintels, sills, shutters, decorative glass, pediments, hoods <br />and hardware. When deteriorated beyond repair, they shall be replaced with units and trim resembling the original. <br />Recommended <br />Wood storm windows and doors painted or finished to match the original should be used but should not damage existing <br />frames. If new sashes or doors are installed, the existing or original materials, design and hardware should be used. <br />When metal storm doors are used, they should be painted, anodized or coated to match the existing. When awnings are used, <br />they should be of canvas material. <br />STAFF RECOMMENDATION: Some of the windows that the applicant intends to replace are not original to the house, and <br />staff would recommend removing and replacing those with a more appropriate and functional window model. The remaining <br />original windows may be repairable, but this process is inconvenienced by the fixed -in-place metal storms on the exterior of the <br />structure. Were 1) the windows to be determined to be deteriorated beyond repair, and 2) given the choice between the two <br />provided window options; staff would recommend that the aluminum -clad exterior / wood interior Quaker Classic Fit windows <br />be utilized for this installation. <br />Written by <br />Adam Toering <br />Historic Preservation Specialist <br />Approved by <br />Elicia Feasel <br />Historic Preservation Administrator <br />Commissioner Anderson made a motion to deny as presented, but encourage the applicant to <br />identify each window, what it is to be replaced with, and that the application fee be waived. <br />Seconded by Commissioner Gordon. <br />Vice President Hertel clarified that votes in the affirmative will support the motion to deny the <br />application and reminded the members to state their reasons when voting. Roll call was ordered. <br />11 <br />
