Fire Sprinkler System Cost

the average cost to install fire protection is $600 or $100 to $2,400

A home fire sprinkler system costs between $200 and $990 but could cost as much as $2,400.

Residential Fire Sprinkler System Cost

Homeowners spend $590 on average to outfit their home with a fire sprinkler system. This form of fire protection is a lifesaving, and money-saving, measure.

A study from 2002 to 2006 found that, compared to houses with only a smoke alarm, houses equipped with both a sprinkler system and smoke alarms experienced the following:

  • 100% fewer deaths

  • 57% fewer injuries

  • 32% less property damage

Additionally, homeowners with fire sprinklers save up to 8% on their homeowner’s insurance.

Commercial Fire Sprinkler System Cost

When a building is under construction, a sprinkler system costs $1 to $2 per square foot covered. This price rises to $2 to $7 per square foot covered when installing the system to an existing building. For high rises, expect to pay at least $4 per square foot covered.

Commercial fire sprinkler systems cost more than residential systems. This is because they cover more space and need a larger water supply.

New Home Fire Sprinkler System Installation Cost

Installing a sprinkler system in a new home that’s still under construction costs anywhere from $0.50 to $4 per square foot. Outfitting a 2,500 square foot home would cost at least $1,250.

You could pay less if you live in a community with a sprinkler ordinance. Places with this ordinance have more businesses competing to install residential sprinklers. Higher competition lowers the market price.

Additional Home Fire Protection

Fire Extinguisher Cost

New fire extinguishers cost $100 to $50 0 and about $30 to $100 to inspect and maintain annually.

The average American household will have a fire large enough to need a fire extinguisher once every 10 years. Adding an extinguisher to your home’s sprinkler system adds necessary fire protection.

Fire Blankets

Fire blankets are highly fire resistant and cost $10 to $100. Most nonflammable blankets may take temperatures of up to 900 degrees and can extinguish small fires. They typically last 7 years and, unlike a smoke detector or extinguisher, won’t need any upkeep.

Smoke Detectors, Heat Sensors & Carbon Monoxide Alarms

Smoke detectors, heat sensors and carbon monoxide detectors are important components to your home’s fire alarm system.

UnitAverage Price Range
Smoke detectors cost$10 - $65
Heat sensors$60 - $100
Carbon monoxide detectors$15 - $150
  • Smoke detectors reduce the chances of fatal fire accidents by 50%. In fact, over 60% of fire-related deaths happened in homes without smoke alarms or working alarms. Check the batteries every 3 months (new batteries cost $5 to $10) and replace your smoke detector every 10 years.

  • Heat sensors not only detect smoke but also when there is a rise in room temperature. When adding a heat sensor to your home’s fire alarm systems, you may have to pay for a monthly monitoring service.

  • Carbon monoxide (CO) is an invisible, odorless and colorless gas that is toxic in high doses. These detectors alert household members when there is an unsafe amount of CO in the home. Check your CO detector to see how long it lasts, but plan on replacing it after 5 to 7 years.

DIY vs. Hire a Professional

Fire sprinkler systems involve complex piping and plumbing work, as well as wiring of alarms and sensors. Without the expert contracting, plumbing and electrical experience for the job, you’ll have flooding and water damage problems at best. At worst, you won’t have help when it’s needed most. Hire a dependable, local fire sprinkler installation company - your life could depend on it!


Can you install your own fire sprinkler system?

Your safety is not worth doing things “on the cheap,” especially when it comes to fire protection. Fires are extremely dangerous and more common than people think. Hire a professional to ensure a safely installed and functioning fire sprinkler system.

How do home fire sprinkler systems work?

Fire sprinkler systems go off when the air temperature spikes to dangerous levels.

  1. A fire causes a spike in air temperature; hot air begins to rise.

  2. Most sprinklers have a glass bulb that’s filled with glycerin. This glycerin expands when exposed to air that’s between 135 and 165 degrees.

  3. As the glycerin expands, it will break the glass bulb.

  4. Once the glass breaks, the sprinklers are set off.

  5. Pressurized water flows out from the sprinklers (this water connects to an outside water source).

What are the types of fire extinguishers?

Fire extinguishers are classified by the type of fire they’re designed to fight.

ExtinguisherType of Fire
Type APaper, wood, fabric and other materials that burn easily
Type BGasoline, grease and other highly flammable liquids or gases
Type CElectrical
Type DIndustrial, burning metals

A fire extinguisher is usually designed to combat more than one type of fire. For example, a Type B, C extinguisher can handle everything from grease to electrical fires.

What is the best fire extinguisher for home use?

Homeowners typically want a Type B, C extinguisher. Because water often works for smaller Type A fires, a Type B, C extinguisher can handle the next level (as well as Type A fires).

What size fire blanket do I need?

The blanket size you need depends on what you’re looking to protect. Smaller blankets measure about 3 by 3 feet, medium blankets are about 6 by 6 feet, and larger blankets are 10 by 10 feet.

You might feel safer with a bigger blanket, particularly if putting out a fire on a person or trying to cover a larger area. Smaller blankets will still work for smaller fires.

Where should smoke and carbon monoxide detectors be placed?

Install at least one smoke and carbon monoxide detector on every floor of your home, as well as in the garage and basement.

Kitchens are a good spot to install a smoke detector. Since you likely won’t want to hear the smoke detector every time you make a spicy stir-fry, install this detector 10 feet away from appliances. Likewise, you might want to place a detector away from or outside of bathrooms so that steam doesn’t set it off.
