As beautiful as Napa, CA is, it’s no stranger to the threat of wildfires. With longer, hotter, and drier fire seasons, homeowners are being urged to take proactive steps in fire-hardening their homes—and spring is the perfect time to start.
The good news? You don’t have to overhaul your entire property to make a real difference. In this blog, we’ll walk you through practical ways to fire-harden your home’s exterior—including siding, windows, decks, and landscaping—before wildfire season arrives.
1. Upgrade to Fire-Resistant Siding
Your siding is the first line of defense against radiant heat and flying embers. In a fire-prone area like Napa, traditional wood or older composite materials can ignite quickly.
🔥 Best fire-resistant siding materials:
- Fiber Cement (e.g., James Hardie) – Non-combustible, durable, and rated Class A for fire resistance.
- Stucco – Cement-based and naturally fire-resistant.
- Engineered Wood (e.g., LP® SmartSide®) – Treated to resist ignition and meets WUI (Wildland-Urban Interface) code. Add LP FlameBlock to achieve a 1-hour fire wall!
🛠️ If your siding is showing signs of rot, gaps, or age—spring is the ideal time to replace it before the dry season.
2. Replace or Reinforce Windows and Doors
Embers love weaknesses, and windows are one of the biggest. Single-pane glass can shatter from intense heat, and embers can enter through warped frames or broken seals.
🌬️ Fire-hardening upgrades for windows and doors:
- Install dual-pane, tempered glass windows.
- Use metal-framed screens instead of plastic or wood.
- Add ember-resistant weather stripping around doors.
- Seal all gaps with fire-rated caulk.
Brands like Andersen, Marvin, Simonton, and Milgard offer windows that meet WUI codes and deliver extra peace of mind.
3. Create and Maintain Defensible Space
Your landscaping can either protect your home or fuel a fire. In Napa County, maintaining defensible space is more than a best practice—it’s often legally required.
🌲 Defensible space tips:
- Clear flammable vegetation within 5 feet of your home (Zone 0).
- Trim trees so branches are at least 10 feet from structures and other trees.
- Replace wood mulch with non-combustible materials like gravel or stone near the home.
- Keep gutters and roofs free of leaves and pine needles.
💡 Bonus Tip: Store firewood and outdoor furniture at least 30 feet away during peak fire months.
4. Upgrade Decks and Fencing
Wood decks and fences can act like wicks, carrying fire right to your home’s siding or windows.
🛠️ Fire-safe decking solutions:
- Use composite or ignition-resistant decking materials.
- Enclose the underside of decks with non-combustible skirting.
- Avoid attaching wood fences directly to your house—create a break with a metal gate or barrier.
Spring is a great time to inspect and retrofit any structures that could carry flames to your home.
5. Seal Vulnerable Areas Around the Home
Even small openings can allow embers to enter your home during a wildfire.
🔍 Check these spots:
- Attic and crawl space vents (use ember-resistant screens)
- Roof-to-wall joints
- Eaves, soffits, and gable ends
- Around utility connections and hose bibs
🧰 A fire-hardened home is a sealed home—so grab that caulk gun this spring.
6. Coordinate with Local Fire Resources
Napa County offers resources and inspections for homeowners looking to comply with defensible space regulations and improve fire safety.
