All balloons are inflated the same day as their scheduled pickup or delivery date in order to maximize their inflated lifespan. While a multitude of factors (e.g. weather) will influence the inflation and durability of a balloon, we provide the following general guidance regarding their lifespan: Latex Balloons w/ Helium: Have a float time of approx. 8 hours. MicroFoil or Metallic Balloons w/ Helium: Float time of approx. 7 days NOTE: Balloons can overheat and pop when left in hot, enclosed spaces (e.g. inside a car) or exposed to direct sunlight. Conversely, placing balloons in front of or under air conditioners or outside on cool days can cause balloons to deflate at a faster rate. Balloon Boutique does not cover damage or deflation caused by mishandling of balloons, contacting them with sharp objects, prolonged exposure to hot/cold temperatures, etc.
