Fire Damage Yard Restoration: What to Expect After a Wildfire | Built to Last Improvements

After a wildfire, the house comes first. Insurance calls, structural inspections, temporary housing. All of that takes priority. But at some point you walk outside and actually look at the yard. Melted fencing. Scorched trees down to black trunks. Ash over everything. The retaining wall is cracked. The irrigation lines are fused shut. The patio is discolored and spalling from heat.

It’s a gut punch, and I won’t pretend otherwise.

I’ve worked on fire damage restoration across the San Gabriel Valley foothills, including properties hit by the Eaton Fire in 2025. For general guidance on recovery, Cal Fire recovery resources is a good starting point. I can’t undo what happened, but I can tell you what the rebuild actually looks like and what to expect along the way.

What does the fire damage restoration process look like?

Every property is different, but the sequence is basically the same. The whole process takes four to six months for a full restoration. Here’s how it breaks down.

Clearing out (the first month)

Nothing gets rebuilt until everything that burned comes out. Charred fencing, melted irrigation lines, destroyed structures, burned trees, and a lot of ash. A mature tree that burned might need professional removal with stump grinding. Concrete cracked by heat needs to be broken out and hauled away.

I also spend time during this phase figuring out what survived. Retaining walls, concrete slabs, and some hardscape can be structurally sound even when they look terrible. I’ve saved homeowners thousands by identifying what can stay versus what actually needs replacing. If a retaining wall took heat damage on the face but the structural core is intact, there’s no reason to tear it out.

Demo and debris removal runs $2,000 to $15,000 depending on lot size, how much burned, and whether I can get equipment in or have to do everything by hand.

The soil problem (weeks 4 through 8)

This is the part that surprises most homeowners, and it’s one of the most important steps. Fire doesn’t just burn what’s above ground. It changes the soil itself.

Intense heat creates what’s called a hydrophobic layer, a waxy, water-repellent band in the soil, sometimes several inches below the surface. Rain hits that layer and slides right off instead of soaking in. On a flat lot, that means puddles. On a hillside in Altadena, that means erosion, runoff, and potential mudslides.

The fire also incinerates the organic material that makes soil fertile. All the decomposed leaves, root matter, and microorganisms that healthy soil needs. Gone. What’s left is basically sterile dirt that won’t grow much of anything without serious amendment.

And then there’s contamination. Ash from burned structures can contain heavy metals, chemicals from treated lumber, melted plastics. Soil testing tells you whether you need remediation before planting.

Fixing the soil means breaking up the hydrophobic layer through deep tilling, adding compost and organic amendments, and in bad cases removing and replacing contaminated topsoil. Budget $1,500 to $6,000 depending on how much area is affected and how bad the damage is.

I know it’s not the exciting part of the project. But I’ve watched homeowners skip soil work, plant a bunch of new landscaping, and lose half of it in the first rainy season because the soil couldn’t hold water or support roots. The soil work makes everything after it actually stick.

Grading and drainage (weeks 6 through 10)

Once the soil is dealt with, the property needs proper grading and drainage. This is non-negotiable in the foothills.

Fire-damaged hillside lots in Altadena, La Cañada Flintridge, and Sierra Madre sit at elevated post-fire landslide risks for one to three years after a burn. The root systems that held the hillside together are dead. There’s no ground cover to slow runoff. When the first real rain comes, everything that isn’t anchored moves.

French drains, surface drains, swales, and sometimes new retaining walls go in during this phase. On a hillside property, this is what keeps your yard from washing out after the first real storm. I’ve installed emergency drainage on properties in October knowing that January rain was coming and there was nothing else holding the slope.

Grading and drainage work runs $3,000 to $12,000 depending on lot size and terrain.

Rebuilding (weeks 8 through 14)

With the ground stable and draining properly, the actual rebuilding starts. Fencing, retaining walls, patios, walkways, pergolas, raised planters. Everything that got destroyed.

Material choices matter more in fire zones than they do elsewhere. Non-combustible or fire-resistant materials are often required for fencing and structures near the home. A fire-rated metal or composite fence costs more than standard wood, but in a Very High Fire Hazard Severity Zone, it’s a requirement. I build back with materials that meet fire code and hold up long-term.

Fencing replacement alone runs $5,000 to $15,000. A full hardscape and structural rebuild can reach $20,000 to $40,000 or more depending on scope.

Planting (weeks 12 through 20)

After months of looking at bare dirt and construction, this is the part that finally feels like recovery. Green things going in the ground.

Landscape installation after fire damage is different from a standard project. The soil has been amended but it’s still recovering. I choose plants that establish quickly, hold soil with their root systems, and comply with defensible space requirements for fire zones. Drought-tolerant natives and Mediterranean plants are the backbone. They establish well in amended soil, use less water, and meet the fire safety guidelines.

More on plant selection on the landscape installation page.

A full landscape restoration runs $5,000 to $20,000 depending on lot size, plant choices, irrigation, and whether you want mature specimens or are willing to let things grow in over a couple of seasons.

What does insurance cover for yard fire damage?

This is where most homeowners hit a wall. Insurance is generally good about some things and frustrating about others. Every policy is different, so check yours, but here are the patterns I see over and over.

Insurance usually covers debris removal (often with a dollar cap), replacement of permanent structures like fencing and retaining walls, damaged hardscape, and tree removal for safety.

Insurance often doesn’t cover, or heavily limits, landscaping and replanting (many policies cap this at $5,000), soil remediation, grading and drainage improvements, irrigation replacement, and material upgrades beyond “like kind” replacement.

The gap is real. Out-of-pocket costs after insurance can run $5,000 to $30,000 depending on how much landscape and drainage work your property needs.

One thing I tell every homeowner: document everything before cleanup starts. Photograph all the damage with something that shows scale. Keep receipts for any emergency work. Get a written assessment from a contractor before you start restoration. Insurance adjusters work from documentation, and the more detailed yours is, the better your claim goes.

What should you know about living in fire country?

The foothill communities sit right at the edge of wildland. Altadena, La Cañada, Sierra Madre. Fires have happened before and they’ll happen again. That’s the reality of living here.

What I can tell you from working on these properties is that yards come back. A lot of them come back better than they were, because the rebuild uses fire-resistant materials, proper drainage, and defensible space design that the original yard probably never had.

Where should you start after fire damage?

Looking at a burned yard is hard. I’ve stood in backyards with homeowners who were trying not to cry, and there’s no script for that moment. My job is to be practical — look at what needs to happen, put it in order, and start.

Don’t rush. The sequence exists for a reason. Skipping soil work or drainage to get plants in faster costs more in the long run.

Get a professional assessment before you commit to a plan or start negotiating with insurance. Have someone walk the property who can tell you what needs to happen and what it’ll actually cost.

If the fire happened during fire season, the first priority is erosion control before winter rains. Temporary measures like erosion blankets and silt fencing can buy time while permanent drainage goes in.

And if budget is tight, phase the work. The critical stuff (debris removal, soil remediation, grading, drainage) protects your property right now. Landscape and finishing work can come in a second round.

Bottom line

Full yard restoration after a wildfire takes four to six months and follows a fixed sequence: debris removal, soil remediation, grading and drainage, structural rebuild, then planting. Insurance covers structures and debris but typically caps landscaping at $5,000 and rarely covers soil work or drainage. Document all damage before cleanup, don’t skip the soil remediation, and phase the work if budget is tight.
