Attic Blown in Insulation – Pricing and Installation Cost Checklist

  • Get at least 3-5 estimates before hiring an Insulation contractor — estimates are typically free, unless it’s a service call for a repair.
  • Expect the price to fluctuate between various companies – each and every company have different operation expenses and over-head.
  • Try to get prices in late Fall, early winter – you should expect aggressive pricing discounts by waiting for a contractor’s down season.
  • Try to budget and additional 7-15% more on top of what our calculator gives out – I.e; difficult configurations, patterns, the additional complexity of your home will add to the costs.
  • Visit every supply house that sell your particular brand of Attic Blown in Insulation and try to negotiate a better price with each supplier – I save on average 20%.
  • Remember, there are multiple styled homes in the U.S – from: Contemporary, colonial, cape-cod style, ranch, bungalow, victorian, etc. So keep that in mind and try to budget a little more, before starting your Attic Blown in Insulation project.
  • Cost can add up quickly, especially if you’re a novice and have never attempted a Attic Blown in Insulation installation before. I would strongly recommend you hire a licensed and Insured Insulation contractor to perform the installation for you.
  • Be sure to have a copy of the Insulation Manufacturer’s recommended installation requirements before starting, to make sure your project doesn’t end up costing you more money in the long-run.
