Source Bank in 2013, exterior trim was either removed or did not exist and was not replaced and has enabled water to enter through the windows, becoming evident upon interior demolition work of removing the plaster. Owner proposes 21 new Anderson 200 vinyl clad windows in the same pattern as existing windows, mostly 1/1 double hung but with four 3/1 double hung in the 1' storey dining room windows. PRESERVATION SPECIALIST REPORT: Today I met the owner of 539 Riverside Dr at the property at 12:30pm. Earlier this morning at 8:30am Troy entered the HPC Office to complete the application he had started the evening before. He had expressed a desire to replace the windows at the property with Anderson Series 200. He had expressed his concerns about being able to repair the existing windows after further investigation by way of removing some of the plaster and trim work. He suggests that the trimwork/tracks from the existing exterior storms had created a channel for water to collect and enter the house. I entered the ground floor of the property where all of the interior trim and several of the plaster walls had been removed. I noticed right away the rough in framework of the lower level had significant deterioration. I also noticed and photographed the buckling and blistering of the plaster underneath the windows as well as the drip trails (water marks) that were still visible where the floor trim had been removed. I photographed each window paying particular attention to the framework and below. It is obvious to me that water has been entering and running down the interior through the plaster lath. Upon further inspection I noticed that in fact the exterior trim was missing as the owner had indicated in his application. This is part of the way in which elements are entering the structure. The windows on the main floor are framed into the brick and they appear to be the worse off. In several locations, the framework is rotted away. The upstairs windows have some of the same water marks and blistering in the plaster. Only one area was down to stud and the wood was wet to the touch on the inside. Although six of the window sashes upstairs are structural sound, they are painted shut and I was unable to see the sills and rails. The plaster is still intact on those and the rough in frame work is unable to be inspected. It is noteworthy that 4 panes of glass have been replaced with plexi -glass. This includes the large sashes on the main floor. The windows on the first floor will have to be removed and the rough in framework replaced where necessary as well as the jambs and sills replaced as well. Currently they are too wet to determine their structural integrity. There are 11 windows on the ground level. There are four (4) double hung 3 over 1 grill pattern, six (6) 1 over 1, and one picture window without grills. The second floor has ten (10) double -hung 1 over 1. Steve Szaday Preservation Specialist STANDARDS AND GUIDELINES: II. EXISTING STRUCTURES C. WINDOWS AND DOORS Window and door frames are in most cases wood. Brick structures have stone sills and brick lintels. In some cases where synthetic siding has been applied, window trim has been covered. Many structures in the district have aluminum storm windows. Some houses retain wood framed storm windows. Required Original windows and doors including sash, lintels, sills, shutters, decorative glass, pediments, hoods and hardware shall be retained or when deteriorated beyond repair, replaced with units and trim resembling the original. Recommended Wood frame storm windows and doors, painted to match the original, should be used but should not damage existing frames. If new sash and doors are used, the existing or original materials, design, and hardware should be used. When metal storm doors are used, they should be painted, anodized or coated to match the existing. When awnings are used they should be of canvas material. Prohibited Original doors, windows, and hardware shall not be discarded when they can be restored and reused in place. New window and door openings which would alter the scale and proportion of the building should not be introduced. Inappropriate new window and door features, such as aluminum and insulating glass combinations that require removal of the original windows and doors, shall not be installed. Not Recommended Awnings, hoods or fake shutters made of metal, vinyl or fiber glass should not be used if they would detract from the existing character or appearance of the building.
