Should I remove attic insulation before installing new materials?

In most cases, it’s best to remove old attic insulation completely, before installing new material. While it’s possible to install new insulation on top of old existing insulation, the best results are derived when the attic space is sealed, insulated, and ventilated anew.

At Four Seasons Insulation, we recommend a removal/retrofit approach for the best results. We do a full inspection of the attic, we remove old insulation material, and we then make necessary repairs. Finally, we air seal the space and insulate with high-quality materials.
