Green Firestop provides safe, affordable and sustainable firestop installation in the Seattle and Portland metropolitan areas and throughout the Northwest.

Designed to resist the spread of fire and restore the integrity of fire-rated walls and floors, many have intumescent properties and expand when exposed to heat, forming a high-strength insulating char.

We use Rectorseal Bio Fireshield™ sealants that restrict the spread of flames, smoke, toxic gases, and water while being both sustainable and cost-effective.
