Historic Window Replacement Approval Process
The process of gaining design review approval for
replacing historic windows is very demanding to-
wards specific criteria required. The applicant must
demonstrate through historic research, thorough
documentation of existing conditions, and by data
analysis that replacement is justified.
Design review is a subjective decision process,
and PMA’s methodology provides a systematic ap-
proach resulting in objective data supporting a
replacement option. The process also includes a
thorough understanding of historic window materi-
al and current window manufacturing and products
in order to assure the most appropriate window re-
placement is presented during the review process. Peter Meijer Architect, PC

Windows help define the ver-
ticality of the design compo-
sition. Replacement windows
must support the initial design
concept.

Windows that need significant work to restore
operation and appearance: Deficiencies
include: surface corrosion on sash/frame,
deteriorated glazing compound and/or setting
bed, cracked/missing glazing, etc.
Previously Replaced
The vast majority of the building’s steel
windows were previously replaced. The
replacement windows do not match the historic
profiles. Where only the sashes have been
replaced, the existing window frames are in
poor condition due to significant corrosion.
Poor Condition
Windows that are difficult/impossible to repair.
Deficiencies include: frames/sashes that have
corrosion section loss, significantly damaged
metal frames, corroded lintel/shelf angles
that have resulted in damaged frames/sashes,
sashes that won’t open due to significant
damage to the sash frame, etc.

Scope of Repair/Storm Windows
Remaining Windows
windowS reMaining in-Place
Scope of work will include the installation of new storm windows at all existing single
paned units in both the Original 1930’s Building and the 1950’s Addition. All wood
windows in both Buildings will be repaired in-place as necessary.
The existing wood windows and units where the original wood windows have been replaced
with steel are glazed with single paned glass. New interior storm windows are to be installed to
provide thermal comfort and reduced energy usage.
The existing wood windows are in varying condition. None of the wood windows currently
have sill flashing and water intrusion is an issue throughout the building. New sill flashing will
be installed at all wood windows as show in subsequent illustrations. Additionally repairs will
be performed as necessary throughout the 1930’s Building and the 1950’s Addition. In-Place
repairs to the existing wood windows will include; New Perimeter sealant will be installed at all
wood windows; All wood windows will be painted to match existing; Frames will be repaired as
necessary.
Remaining Windows: Scope of Repair/Storm Windows
Details portray knowledge of archaic construction techniques and new installation processes.

Historic Window Replacement Approval Process

  • 1. Peter Meijer Architect, PC Historic Window Replacement Approval Process The process of gaining design review approval for replacing historic windows is very demanding to- wards specific criteria required. The applicant must demonstrate through historic research, thorough documentation of existing conditions, and by data analysis that replacement is justified. Design review is a subjective decision process, and PMA’s methodology provides a systematic ap- proach resulting in objective data supporting a replacement option. The process also includes a thorough understanding of historic window materi- al and current window manufacturing and products in order to assure the most appropriate window re- placement is presented during the review process.

All wood windows in both Buildings will be repaired in-place as necessary. The existing wood windows and units where the original wood windows have been replaced with steel are glazed with single paned glass. New interior storm windows are to be installed to provide thermal comfort and reduced energy usage. The existing wood windows are in varying condition. None of the wood windows currently have sill flashing and water intrusion is an issue throughout the building. New sill flashing will be installed at all wood windows as show in subsequent illustrations. Additionally repairs will be performed as necessary throughout the 1930’s Building and the 1950’s Addition. In-Place repairs to the existing wood windows will include; New Perimeter sealant will be installed at all wood windows; All wood windows will be painted to match existing; Frames will be repaired as necessary. Remaining Windows: Scope of Repair/Storm Windows Details portray knowledge of archaic construction techniques and new installation processes.

Detail Images Detail images taken from the interior document specific deficiencies, unique, and severe conditions. Arrows are used to call out specific items. Window Survey Sheets Each assessed window has a unique survey sheet that documents the general and specific deficiencies identified in the field. Window Type The window type describes the material, configuration, and operation of each type. Material: A - Aluminum, S - Steel, W - Wood Number of Lites Operation: D - Double Hung, S - Single Hung, F - Fixed, A - Awning/Hopper, C - Casement Unique Identifier General Notes Overall deficiencies apply to the general condition of the entire window. These deficiencies are noted in either the left hand column of deficiencies and/or with circled keynotes adjacent to the window elevation. Deficiencies are not typically noted in both locations. Window Condition Windows were given one of the following conditions based off of the extensive field survey. Typical conditions include: Surface Defects Moderate Condition Poor Condition Previously Replaced Window Number Each window is uniquely identified and elevations identify the specific location of each window. Number describes location and orientation of each window. Floor Level Elevation Numbered Right to Left Specific Deficiencies Localized deficiencies are typically noted with keynotes/ text on each window elevation. Location and extent of deficiencies are clearly drawn and called out. Surface Defects Windows that need minimal tune-ups to restore operation and appearance. Deficiencies include: deteriorated paint, missing weather-stripping, deteriorated sealant, missing hardware, etc. Typical Window Conditions: Moderate Condition Windows that need significant work to restore operation and appearance: Deficiencies include: checked frames/ sashes, minimally reinforced sashes (screws holding wood components together), surface corrosion on sash/frame, deteriorated glazing compound, cracked/missing glazing, etc. Poor Condition Windows that are difficult/impossible to repair. Deficiencies include: significantly deteriorated frames/sashes where wood is beyond repair, sashes that have been significantly reinforced with metal angles/brackets and that need additional reinforcement, frames/ sashes that have corrosion section loss, significantly damaged metal frames, corroded lintel/ shelf angles that have resulted in damaged frames/sashes, sashes that won’t open due to significant damage to the sash frame, etc. Previously Replaced Windows where the majority of the historic material has been removed and replaced with not in-kind units.
