William Neal
I had a very good experience with Northwest Crawl Space. Our Sales Rep William was extremely helpful as he explained the entire process very well. He also educated us on the energy rebates available from PSE which Northwest applied to our project cost. William also called us on the day of our installation, and followed up after our project was completed. The installation crew communicated well and worked extremely hard. We are very pleased with the outcome of this project.
