2024 PSE Residential & Commercial Insulation Energy Rebates

We joined Puget Sound Energy’s Contractor Alliance Network in 2013. We’ll make sure you receive maximum savings for your insulation services. Starting in 2024 PSE removed the maximum sq ft. discount you’re able to receive. Its good time to upgrade to spray foam for around the cost of fiberglass insulation. Large commercial and industrial customers can receive rebates as well.
