A professionally installed wildfire sprinkler system can cost anywhere from $15,000 to $100,000+, depending on the size of the home, property layout, number of structures, amount of vegetation, and how far out from the home the owner wants protection.
For many residential properties, the average Big Sky Fire Defense system is around $20,000.
That may sound like a wide range, but wildfire protection is not a one-size-fits-all product. A 2,000-square-foot home on a small lot does not need the same system as a large mountain estate surrounded by timber, decks, guest houses, shops, and heavy vegetation.
Wildfire Sprinkler System Cost Range
| Property Type | Estimated Cost |
|---|---|
| Small residential home / small lot | Around $15,000 |
| Average residential home | Around $20,000 |
| Large estate / ranch / multiple structures | $50,000–$100,000+ |
| Backup power upgrade | Usually $1,000–$2,000 |
| Annual system checkup | Starts around $500/year |
| App connection | Around $15/month |
These are general ranges. Final pricing depends on the property, system design, amount of CitroTech needed, and the level of protection the homeowner wants.
What Is Included in a Big Sky Fire Defense System?
A typical Big Sky Fire Defense wildfire protection system includes:
- Tank
- Pump or pumps
- Piping
- Sprinkler heads and spray nozzles
- App-based remote activation
- CitroTech fire inhibitor
- Labor and installation
For an average 2,000-square-foot home, a typical system is designed to protect the home and nearby combustible areas. That may include vegetation, trees, bushes, landscaping, decks, exposed wood, and other vulnerable areas around the structure.
Backup power is not automatically included, but it can usually be added for approximately $1,000 to $2,000, depending on the property and system setup.
What Affects the Cost of a Wildfire Sprinkler System?
The biggest cost driver is the size of the home.
A larger home requires more piping, more sprinkler heads, more fittings, more labor, more installation time, and more CitroTech fire inhibitor.
The second major factor is the amount of area being protected.
Some homeowners want to protect the structure and the vegetation directly around the home. Others want to extend protection 100 to 200 feet out to create a wider CitroTech-treated fire break around the property.
Other cost factors include:
- Number of structures being protected
- Size and layout of the home
- Number of sprinkler heads needed
- Tank size
- Number of pumps
- Distance from the tank to the home
- Amount of vegetation being treated
- Number of trees, shrubs, decks, fences, and outbuildings
- Whether the property needs one system or multiple systems
- Whether backup power is added
- Access and terrain around the home
On larger estates, one system may not be enough. Some properties require two separate systems, which may mean two tanks, two pumps, separate piping runs, more spray heads, and more installation time.
What Does the System Actually Do?
A Big Sky Fire Defense system is not designed to fight a wildfire after it arrives.
It is designed to be deployed before the fire gets there.
Our systems apply CitroTech fire inhibitor to combustible areas on and around the home, creating a proactive chemical fire break.
That distinction matters.
A traditional water-only sprinkler system tries to wet the structure during a wildfire event. A Big Sky Fire Defense system is designed to coat combustible surfaces before the ember storm or fire front reaches the property.
The goal is to reduce ignition risk before the fire arrives.
Water-Based Systems vs. CitroTech-Based Systems
Traditional water-based wildfire sprinkler systems rely on continuous water application during a wildfire or ember storm.
Water can help. We are not saying water systems never work.
But water-only systems usually require much larger storage and longer run times because they are trying to keep the structure wet during the fire event.
That creates real-world problems.
High winds can blow water off target. Ember storms can last longer than expected. Domestic water and well water may not keep up with demand. Municipal water pressure can drop during emergencies. Power outages can affect pumps.
And then there is water storage.
Some water-based systems may require a large tank, reservoir, swimming pool, pond, high-output well, or municipal water supply with enough pressure and flow to keep up.
In Montana, Idaho, Wyoming, and other cold-weather states, storing thousands of gallons of water is not simple. A 5,000- to 10,000-gallon water tank is large, expensive, and difficult to place. If it is above ground, it may need to be drained every winter and refilled in the spring. If it is buried below the frost line, that adds major excavation and installation cost.
Big Sky Fire Defense systems are different.
We still use tanks, pumps, piping, remote activation, and high-quality spray heads, but we are not trying to continuously soak the house with water during the fire.
Our systems deploy CitroTech before the fire arrives.
Because of that, our tanks are typically much smaller — often around 100 to 275 gallons, sometimes more depending on the property — instead of requiring massive water storage.
What About New Construction?
New construction pricing for a wildfire defense system is usually not dramatically different from a retrofit system, but new construction offers one major advantage.
We can access framing, lumber, and exposed beams before the home is closed in.
That allows Big Sky Fire Defense to treat exposed wood components with CitroTech during construction. This will give your framing a Class A fire assembly. CitroTech 34 (MFB-34) is third-party certified for Class A fire protection on wood under DrJ TER 2504-101 and tested to the ASTM E84 and E2768 standards.
The cost for framing, lumber, and exposed beam treatment is typically around $0.50 to $1.00 per square foot, depending on the project.
It is always easier to build protection in early than to bolt it on later.
Does the System Need Annual Maintenance?
Yes.
Big Sky Fire Defense recommends an annual system checkup.
Annual system checkups start around $500 per year, depending on system size, location, number of sprinkler heads, pumps, and whether any repairs or adjustments are needed.
A typical annual checkup may include testing the system with water, checking spray coverage, aiming sprinkler heads, inspecting pumps, checking electrical components, testing remote activation, blowing out the system afterward, and verifying CitroTech supply if needed.
Because our systems are dry until deployed, traditional winterization is not the same as a wet sprinkler system. The lines are not sitting full of fluid all winter.
Is There a Lower-Cost Option?
Yes.
For homeowners who are not ready for a permanent tank, pump, piping, and remote-activation system, Big Sky Fire Defense also offers seasonal CitroTech spray treatments.
This is a lower-cost way to add protection during wildfire season.
Instead of installing a permanent system, we come to the property and apply CitroTech directly to combustible areas on and around the home.
This can include vegetation, landscaping, decks, fences, exposed wood, outbuildings, and other vulnerable areas.
The treatment typically lasts around three months, which lines up with the core wildfire season in many Western states. Depending on weather, a touch-up may be needed after a heavy rain event, especially after roughly 2 inches of rain.
Pricing for seasonal spray treatment depends on property size, vegetation, access, amount of material needed, and the areas being treated.
Is a Wildfire Sprinkler System Worth the Cost?
For many homeowners in wildfire-prone areas, yes.
Especially with rising insurance rates, stricter underwriting, and some homeowners losing coverage entirely.
A wildfire defense system is not just another home upgrade. It is a way to protect the structure, landscaping, property value, neighborhood, and people who may be asked to defend that area during a fire.
There is also a responsibility piece here.
If you choose to live in the wildland-urban interface, you have to take wildfire seriously. That does not mean living scared. It means being prepared.
Your home is not sitting by itself in a bubble. If one house ignites, it can create more heat, more embers, and more risk for surrounding properties.
Protecting your home helps protect your neighbors too.
A $15,000 to $20,000 wildfire defense system can feel expensive until you compare it to the cost of losing a home, fighting through a complicated insurance claim, living somewhere else during repairs, rebuilding in a tight construction market, and trying to put your life back together.
You can read more about that in what really happens after your house burns, and in how long it takes to rebuild after a wildfire.
The cleanest claim is the one you never have.
No System Can Guarantee Survival in Every Wildfire
No wildfire protection system can guarantee that a home will survive every wildfire.
Wildfires are unpredictable. Wind, ember storms, fuel loads, terrain, drought conditions, construction materials, access, and surrounding vegetation all matter.
But that does not mean homeowners are helpless.
A properly designed CitroTech wildfire defense system can help reduce ignition risk by coating combustible materials before the fire arrives.
The goal is not to promise that fire can never touch the property.
The goal is to give the home, landscaping, and surrounding structures a better chance when wildfire conditions move in.
