The basic rule of thumb to estimate the cost is to add one and a half percent to the cost of the home. They can also be installed in existing homes. Costs for those systems vary among construction type. The first myth is that the water damage from fire sprinklers is worse than the fire. A sprinkler will control a fire with a fraction of the water used by our hoses.
Sprinklers act quickly.
This quick action doesn't allow the fire to build up heat and toxic gases. Allowing you, the homeowner more time to escape. If one sprinkler head goes off, they all will. Again, not true. Automatic sprinklers spray water only the immediate area of the fire thus avoiding widespread water damage.
