Ember-Resistant Vent Retrofitting
Your Home Wasn't Built for Modern Wildfires.
Wind carried embers are one of the leading causes of home ignition during wildfires, often entering through outdated attic and crawl space vents long before flames reach the property.
Ember resistant vent upgrades are a simple and cost effective way to help protect your home, improve wildfire readiness, and take proactive steps before fire season begins.

What We Retrofit on Your Home.
Every non-plumbing vent on your home gets either a listed ember-resistant unit or 1/8" corrosion-resistant metal mesh, whichever the WPH standard prescribes for that opening.
- Roof vents — ridge, off-ridge, and through-roof
- Attic gable-end vents
- Attic eave and soffit vents (open eave or boxed soffit)
- Foundation and crawlspace vents
- Dryer and central-vacuum exhaust vents (louver inspected, never meshed)
- Plumbing vents excluded — the WPH standard does not require these to be retrofitted
Manufacturers we install include Vulcan Technologies, Brandguard, and O'Hagin. Specs and finishes vary by opening — we match the right product to the location.
