historic window replacement approval process

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.

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

Moderate ConditionWindows 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 ReplacedThe 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 ConditionWindows 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

w i n d o w S r e M a i n i n g i n -P l a c e

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.

Surface DefectsWindows that need minimal tune-ups to restore operation and appearance. Deficiencies include: deteriorated paint, missing weather-stripping, deteriorated sealant, missing hardware, etc.

Moderate ConditionWindows that need significant work to restore operation and appearance: Deficiencies include: checked frames/sashes, minimally reinforced sashes (screws holding wood components together), deteriorated glazing compound, cracked/missing glazing, etc.

Poor ConditionWindows 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, 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.

Window Survey Sheet

Overall Exterior PhotographExterior photographs of assessed windows show general deficiencies and overall condition.

Detail ImagesDetail images taken from the interior document specific

deficiencies, unique, and severe conditions. Arrows are used to call out specific items.

Window Survey SheetsEach assessed window has a unique survey sheet that documents the general and specific deficiencies identified in the field.

Window TypeThe 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 NotesOverall 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 ConditionWindows were given one of the following conditions

based off of the extensive field survey. Typical conditions include:

Surface DefectsModerate Condition

Poor ConditionPreviously Replaced

Window NumberEach window is uniquely identified and elevations identify

the specific location of each window. Number describes location and orientation of each window.

Floor LevelElevation

Numbered Right to Left

Specific DeficienciesLocalized deficiencies are typically noted with keynotes/

text on each window elevation. Location and extent of deficiencies are clearly drawn and called out.

Surface DefectsWindows 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 ConditionWindows 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 ConditionWindows 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 ReplacedWindows where the majority of the historic material has been removed and replaced with not in-kind units.
