Helene Madison Pool Completed Renovations

Helene Madison Pool, built in 1970, is a thriving public pool facility for residents in north Seattle. It offers year-round programs and lessons for adults and children alike, and hosts a majority of the local school competitive swim meets.


In 2016, Seattle Parks and Recreation identified upgrades needed to various pool and community facilities throughout the city. The Stemper AC Team worked on renovations and improvements on seven public pools, with one of the most recently completed being Helene Madison Pool. The scope of work here included replacement of the dated exterior building envelope and roofs, a facelift of the interior lobby, and various infrastructure updates.

Before renovations began


The original pool building exterior includes diagonal set wood tongue and groove board cladding, asphalt shingles at steep-slope roof areas, and membrane roofing at the low-slope roof. As part of our team’s detailed facility assessment, significant improvements were required for both infrastructure components and exterior building modifications due to issues associated with aging and long-term use. This provided us the opportunity to refresh the aged exterior and give the building a new identity in the local neighborhood.

Completed roof replacement

SBS Modified Bitumen membrane roofing was used to replace the existing single-ply roofing membrane at the low-slope roof, while laminated asphalt shingles were installed at the steep-slope roof areas.

Approximately eighty percent of the building is surrounded by vegetation and flora for much of the year, so neutral-toned fiber cement cladding panels were used in these areas. At the main entry, customized metal shingles cover the most visible facades of the building.

Metal shingles at exterior entryway


The exterior entryway and interior lobby were also partially renovated with new lighting and coatings to energize and enliven the space and increase the visibility of these formerly dark cave-like areas. Additional improvements planned for the near future will complete the improvements in the lobby area.
