Ember-resistant vents & ember entry protection

Vents are one of the most common ways embers get inside a home. Replacing them is often the highest-value hardening upgrade per dollar.

Attics and crawlspaces need ventilation, which means openings. Standard vents use coarse screen that lets wind-driven embers straight into the attic, where they land on dust, insulation and framing. Ember- and flame-resistant vents keep air moving while blocking embers and resisting flame.

We survey every vent on the house (foundation, gable, soffit, eave and roof-edge openings) and replace them with tested ember-resistant products such as Vulcan vents, sized to keep the required ventilation. While we are there, we close the other gaps embers use: open eave blocking, gaps at the roof edge, unscreened openings and worn weather stripping.

What affects the scope

Every property is different, so we price from a site visit rather than a guess. These are the things that change the scope and cost most.

  • Number, size and type of vents
  • Access to attic, eaves and crawlspace
  • Height and roof pitch
  • Condition of surrounding siding, trim and framing
  • Whether eaves are open or boxed

How it works

  1. 01

    Site visit

    We look at the property and the specific conditions, and talk through what you want to accomplish.

  2. 02

    Clear scope & estimate

    You get a written scope that explains what we recommend, why, and what can be phased.

  3. 03

    Build

    Owner-led work, documented with photos, including anything concealed before it's covered.

  4. 04

    Walkthrough

    We review the finished work with you and leave you with the documentation.

FAQ

Common questions

Will ember-resistant vents reduce attic ventilation?

They should not when they are sized correctly. We calculate the vent area the house needs and choose products and quantities that maintain it.

Can I just add finer mesh to my existing vents?

Fine mesh helps but clogs, and it does not resist flame. Tested ember- and flame-resistant vents are the more durable solution, especially on gable and soffit vents.

Is this something a program like CWMP covers?

Vent replacement is a common part of hardening programs. If you are in a program, we can work within its scope; if not, it is an affordable place to start privately.
