Responsive and caring
When my basement flooded, Grant & Warren Insurance was the first call I made. They walked me through the claims process and followed up regularly. A+ service.

Lost my documents
Grant & Warren Insurance lost some of my paperwork during the home insurance application process. Had to resubmit everything. Very unprofessional experience.

Average experience
My experience with Grant & Warren Insurance was average. They found decent auto insurance rates but nothing spectacular. Communication could be improved.
Hassan Wong
Room for improvement
Grant & Warren Insurance handled our business insurance, but the process was slow and I had to follow up multiple times. The final policy was fine though.
