Defensible space is the managed buffer of cleared and thinned vegetation around your home. It gives a wildfire less to feed on, drops the flames closer to the ground, and gives firefighters somewhere safe to stand and defend the house. We’re firefighter-led, so this is the work we know best.
It doesn’t mean bulldozing your land or losing the trees you like. It means managing the fuel close to the house so flames can’t climb from the grass to a shrub to a low branch and right up to your roofline.

How defensible space works
Most properties around here break into three zones, and each one gets treated differently.
The first 5 feet, right up against the house, matters most and gets ignored most. Bark mulch against the siding, dry needles in the gutter, a juniper hugging the wall. That’s what embers land in. We pull the fuel back off the structure.
From 5 to 30 feet, we break things up. Shrubs get spaced out, low branches come off, dead material gets cleared, and anything that lets fire ladder upward gets removed.
From 30 to 100 feet, we thin and clean up. We keep the healthy trees, open the spacing between them, and haul off the brush and slash that’s been building for years.
What the work includes
Every property is different, but defensible space work usually pulls in several of the things we do: brush and fuel clearing, limbing up trees, thinning crowded stands, and hauling off everything we cut. Slope, tree density, and what’s growing all change the plan, which is why we walk the property before quoting it.
Why it's worth doing
Studies cited by the Washington Department of Natural Resources suggest as many as 80% of homes lost to wildfire might have been saved with defensible space. It’s usually embers, not a wall of flame, that take a house, and embers find the dry, overgrown spots you didn’t get to. Defensible space is the fix, and there’s a window every spring and early summer to get it done before things dry out.
It can help on the insurance side too. A lot of homeowners here are seeing wildfire-related non-renewals and rate hikes, and documented defensible space gives you something real to show your carrier.
Frequently asked questions
How much defensible space do I need?
It depends on your slope, your trees, and how your home is built, but most properties manage three zones out to about 100 feet. We walk it with you and tell you what actually needs doing.
Do I have to cut down my trees?
No. Good defensible space keeps the healthy trees. We thin, space, and limb so the trees that stay are an asset, not a fuse.
Is this the same as the DNR cost-share work?
Often yes. Defensible space is exactly the kind of work those programs fund. We do it to spec and document it, though the program approval has to come before the work starts.
How long does it take?
A city lot might be a day. Forested acreage can take longer. We'll give you a real timeline with the estimate.
