Your home deserves a plan.SEDONA & VERDE VALLEY, ARIZONA
01 / A CONSIDERED APPROACH
Preparedness is
a series of
thoughtful choices.
Your home is more than a structure. It’s the life you’ve built around it.
Cornerstone Wildfire Defense brings a property-focused approach to temporary wildfire-retardant treatment in Sedona and the Verde Valley. Our application service uses Clore fire retardant, with treatment planned around the areas that matter to you.
Treatment is one part of preparation, alongside defensible space, property maintenance, and an evacuation plan. It does not make a property fireproof or guarantee protection.
How treatment planning works ↗02 / WHAT WE TREAT
Focus on the details.
Consider the whole property.
Manufacturer-approved combustible surfaces and vegetation, selected for your property’s needs.
Vegetation & landscaping
Shrubs, brush, and tree treatment areas where product guidance supports application. Mature piñon and juniper are assessed individually for suitable treatment and access.
Areas around your home
Targeted treatment of eligible materials near structures, guided by the layout and conditions of your property.
Temporary treatment only. No construction, permanent coatings, or fire-suppression system installation. Sensitive surfaces require assessment and a small-area test.
03 / THE PRODUCT WE APPLY

04 / FIND YOUR STARTING POINT
Plan for your trees,
shrubs & brush.
Include the piñon, juniper, shrubs, and brush around your home in your property plan. Mature trees—including trees 10 feet and taller—receive a tailored assessment. Use the slider below for lower vegetation coverage and package pricing.
Smallest package: 5 gallons. For bushes 2–4 feet tall, that is approximately 250 sq ft of treated vegetation—a 10 × 25 ft area. This example does not apply to mature tree trunks.
ESTIMATED APPLICATION SERVICE
10 finished gallons · Cornerstone application service
Preview pricing, subject to property review. Gallons refer to the ready-to-apply treatment used on your property. Larger properties and commercial sites receive a custom estimate. Final total and any applicable tax will be confirmed before booking.
Continue to my property plan ↗Calculate your trunk area
For a straight trunk, area is the distance around the trunk multiplied by the treatment height. Count each stem separately for a multi-stem tree.
Use the widest trunk diameter in the treated section for this simple cylindrical estimate.
Trunk surface only. Branches, foliage, bark texture, overspray, and access can change the product needed. A trunk calculation is not a whole-tree treatment estimate.
Have a coverage rate from Cornerstone? +
No mature-bark rate was found in Clore’s published guidance. Use a rate confirmed for your treatment, not the grass or small-bush rate.
LOWER VEGETATION COVERAGESQ FT
Have a lawn or low weeds? +
Each estimate uses all selected gallons on one vegetation type. For a mix of shrubs and brush, the gallons are shared across those areas. These are treated vegetation areas—not your home’s floor area. Actual coverage depends on density and application conditions.
The square-foot figures above apply only to the listed vegetation heights. Larger trees receive their own assessment; these figures do not estimate whole-tree coverage.
Coverage guidance uses Clore’s published application rates: 50 sq ft per finished gallon for bushes and small trees, and 100 sq ft for lower brush.

A FEW GOOD QUESTIONS
Before you
get started.
Does treatment make my home fireproof? +
No. Temporary retardant treatment does not guarantee protection or replace defensible space, maintenance, or evacuation instructions.
How many gallons will my property need? +
That depends on the actual surfaces and vegetation being treated. The coverage tool provides a starting point for vegetation, not an estimate based on your home’s floor area.
Can I book an exact appointment time? +
The planned booking model uses service days. An arrival window will follow so routes can account for property size and treatment requirements.
When will my card be charged? +
When booking opens, you’ll securely add a card on file to hold your service-day reservation. Your card will be charged on the day of service. The final amount and payment terms will be shown before you confirm your booking.
Can I book or pay today? +
Not yet. This is a private website preview. Live availability, property uploads, reservations, and Square payments will be enabled before launch.
Who provides my treatment service? +
Cornerstone Wildfire Defense provides your property’s fire-retardant application service. Clore fire retardant is the product we use. Start with our coverage guide, then plan your Cornerstone service. Product testing references are available under technical sources.
