CASE STUDY

408 West Florida Street in Milwaukee, WI

Hellenbrand Glass of Waunakee, WI renovated a former candy factory in Milwaukee’s dynamic Third Ward neighborhood.  250 windows are were meticulously restored.  The seven story building is now housing ninety apartments along with retail and restaurant options on the street level.

  • This project began in September, 2014 and was slated to be complete well ahead of the scheduled deadline of June 24th, 2015.
  • Created off-site window workshop a few blocks from the project site.  The workshop allows work to continue in a temperature controlled environment throughout the winter.
  • Repair process ensures that each sash, sill, and frame is carefully inspected several times by different craftsmen over the course of the window’s repair.
  • The window sashes were removed from the building and carefully labeled.  Back in the workshop they are arranged based on the location and floor of the building from which they came.  Then the sash are worked around the room in assembly-line fashion. The glazing and glass are carefully removed.  (Unfortunately, only a very small percentage of the original glass was still intact, so all of the glass is being replaced.) Next, the paint is stripped using a variety of methods, depending on the sash’s condition.  The team uses heat-removal, low VOC paint strippers, and good old-fashioned sanding and scraping.
  • Once the paint has been stripped, the sash are disassembled and inspected to identify areas that require epoxy repairs.
  • Finally, the sash are sanded and primed with oil-based primer.  The primer helps to identify any areas that might have been overlooked during the first pass through the room.  Any minor touch ups required after priming are addressed with oil-based spackle.
  • Crew hung plywood sheets on hinges over the window openings allowing access to the sills from the interior of the building.  By utilizing heaters, the restoration process can continue year-round.
