Repointing shall not be done with a mortar of high Portland cement content which can often create a bond that is stronger tha n <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 /> <br />Unpainted masonry surfaces shall not be painted unless they had been painte d originally. Paint shall not be removed from <br />masonry surfaces by any means that damage the surface. <br /> <br />[…] <br /> <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 l intels. In some cases where aluminum siding <br />has been applied, the window and door trim has been covered. About half of the structures in the district have aluminum stor m <br />windows; the other half have wood storm windows. <br /> <br />Required <br />Original windows and doors shall be retained including sashes, lintels, sills, shutters, decorative glass, pediments, hoods a nd <br />hardware. When deteriorated beyond repair, they shall be replaced with units and trim resembling the original. <br /> <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. When <br />metal storm doors are used, they should be painted, anodized or coated to match the existing. When awnings are used, they <br />should be of canvas material. <br /> <br />D. ENTRANCES, PORCHES AND STEPS <br />Most houses in the district have either an open or enclosed porch across the front. Mo st porches have either hip or gabled roofs <br />or are covered by the main roof of the house. <br /> <br />Required <br />When deteriorated beyond repair, existing or original porches, stoops, patios and steps, including handrails, balusters, <br />columns, brackets, tiles and roof decorations, shall be retained or replaced by replicas of the same design or by a design <br />more in keeping with the historic period of the structure. <br /> <br />Porches and additions reflecting later architectural styles and which are important to the building’s histori cal integrity shall be <br />retained. <br /> <br />Recommended <br />When enclosing porches for heat conservation or for other reasons, it should be done in a manner that does not alter the <br />architectural or historical character of the building. <br /> <br />Not Recommended <br />Original porch details should not be replaced with materials representing a different period or style from the original. <br />[…] <br /> <br />SITE VISIT FINDINGS: <br />The later additions are unsympathetic and detract from the historic character of the home. The spiral staircase has <br />deteriorated and is ‘spongy’. Unveiling the house will reveal original features; this may also indicate the previous <br />configuration of the rear of the house. <br /> <br />STAFF RECOMMENDATION: Staff recommends approval. <br /> <br />Prepared by <br />Adam Toering, Historic Preservation Specialist
