Jim Kemp
Northwest did a great job on our messy sewer backup in the foundation space. They were fast, responsive, and communicating openly and honestly. Particular laurels to their project manager, Patrick. He moved the project forward in response to our stress, and when a miscommunication occurred with their field crew that caused more work than they bid, they took it on the chin. That’s integrity and good will! Thank you. Jim & Linda
