Waterproofing Construction Leads in Seattle (2026): 531 Projects in the Award Window
To find waterproofing construction leads in Seattle, work from building permits and time the call to the build stage. On October 9, 2026, 531 permitted projects in the City of Seattle were still at the point where waterproofing is awarded. The general contractor awards waterproofing around the foundation and the building envelope; an envelope consultant or the architect often specifies the system. Builtie reads the permits, estimates each project's stage and attaches the builder or general contractor with a verified decision maker.
The same four steps, whether the buyer is a builder, a designer, an owner or a company you want to acquire.
How many waterproofing projects are open in Seattle right now
| Measure | Seattle |
|---|---|
| Projects in the waterproofing award window | 531 |
| New buildings / renovations and alterations | 322 / 209 |

61% of them are new buildings and 39% are renovations, additions or alterations: a mix of ground-up builds, where the builder decides, and renovations, where the owner or designer often does. Because waterproofing is bought early, the 441 projects permitted in the last 90 days are the ones to call first; 83% of the count is that recent. Seattle ranks 10 of 25 markets Builtie covers for waterproofing, behind Vancouver (537 projects).
A project counts when its permit was issued in the last four years, the build is still inside the stage when waterproofing is awarded, and the job is big enough to be worth quoting: at least $8k of waterproofing work. Trade sub-permits are grouped into their parent project, so this is a count of projects, not permits.

What the Seattle data covers
Seattle's feed rarely names the builder: 1.4% of new-build permits carry one. Builtie resolves the company behind a Seattle project from other records, and does not publish a Seattle builder count because it would describe the feed rather than the market.
If you work from Bellevue, Redmond, Kirkland, Renton, Everett and Tacoma, Builtie shows you this feed as your nearest covered market; those cities' own permits are not in the count above.
