Original exterior wall materials in the District range from brick, clapboard, shingles, and masonry block to aluminum siding. In the majority
<br />of the cases the aluminum siding has been applied over the original clapboard. There are some masonry commercial buildings on
<br />Lincolnway.
<br />Required
<br />Existing exterior building materials shall be retained. Deterioration of wood materials shall be prevented through repair, cleaning, and
<br />painting. The existing architectural detail around windows, porches, doors, and eaves should be retained or replaced by replicas of
<br />the same design and materials when deteriorated beyond repair.
<br />Masonry structures shall be maintained, tuckpointed and properly cleaned when necessary. Masonry shall be cleaned only when necessary to
<br />halt deterioration or to remove stains, and shall be done with the gentlest method possible, such as low pressure water and soft natural bristle
<br />bushes.
<br />Stucco surfaces shall be maintained by cleaning and repainted when necessary. When repairing stucco a stucco mixture shall be used.
<br />Recommended
<br />Whenever possible, the original building materials should be restored.
<br />Aluminum or vinyl siding may be used when it is the only feasible alternative to maintaining the original surface material. When used over
<br />wood surfaces, this siding should be the same size and style as the original wood. However it must be noted that such material can contribute
<br />to the deterioration of the structure from moisture and insects.
<br />Mortar joints should be repointed only when there is evidence of moisture problems or when sufficient mortar is missing to allow water to
<br />stand in the mortar joint. Existing mortar shall be duplicated in composition, color, texture, joint size, method of application, and joint
<br />profile.
<br />Prohibited
<br />Wood siding shall not be resurfaced with new material, such as artificial stone, brick veneer, asbestos or asphalt shingles, which is
<br />inappropriate or was unavailable when the building was constructed. Sandblasting or the use of harsh detergents shall not be used on
<br />masonry or stucco. This method of cleaning erodes the surface material and accelerates deterioration.
<br />Not Recommended
<br />Waterproof or water repellant coatings or surface consolidation treatments should not be used unless required to solve a specific problem that
<br />has been studied and identified. Coatings are frequently unnecessary, expensive, and can accelerate deterioration of the masonry. Mortar
<br />joints which do not need repointing should not be. Repointing should not be done with mortar of high Portland cement content, which can
<br />often create a bond that is stronger than the building materials. This can cause deterioration as a result of differing coefficient of expansion
<br />and the differing porosity of the material and the mortar, which can result in serious damage to adjacent brick. Paint should not be removed
<br />from masonry surfaces indiscriminately.

<br />b. WINDOWS AND DOORS
<br />Windows and door frames are in nearly all cases wood. Brick structures have stone sills and brick lintels; masonry block structures have
<br />masonry sills and lintels. In some cases where aluminum siding has been applied window trim has been covered. About half of the
<br />structures in the district have aluminum storm windows, the other half wood storm windows.
<br />Required
<br />Original windows and doors including sash, lintels, sills, shutters, decorative glass, pediments, hoods, and hardware shall be retained
<br />or when deteriorated beyond repair, replaced with duplicates of the existing or original.
<br />Recommended
<br />Wood frame storm windows and doors, painted to match the existing or original, should be used but should not damage existing frames and
<br />should be removable in the future. If new sash and doors are used, the existing or original materials, design, and hardware should be
<br />used. When 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 />Prohibited
<br />Existing or original doors, windows, and hardware shall not be discarded when they can be restored and re-used in place. New window and
<br />door openings which would alter the scale and proportion of the building should not be introduced. Inappropriate new window and door
<br />features such as aluminum insulating glass combinations that require the removal of the original windows and doors shall not be
<br />installed.
<br />Not Recommended
<br />Metal, vinyl, or fiberglass awnings, hoods, and fake shutters that would detract from the existing character or appearance of the building
<br />should not be used.

<br />SITE VISIT REPORT:
<br />On April 29th, 2021, Specialist Adam Toering and Inspector Ross Van Overberghe met Mr. Turnock at the property
<br />to document the condition of the existing windows and discuss long term changes to the property. The existing
<br />windows installed in 1983(?) appear to be wood double-pane windows. Multiple windows have begun to ‘fog up’,
<br />indicating that the window seal has been broken between the panes of glass. Two of the windows on the street
<br />facing façade have additional black metal storm/screen units installed.
<br />
<br />STAFF RECOMMENDATION: Staff recommends denial.
