Made insurance easy
Insurance has always been confusing to me, but the team at GrandMount Insurance Brokers explained everything in plain language. Got great tenant insurance coverage at a fair price.

Fair pricing
GrandMount Insurance Brokers offered fair pricing on our commercial insurance package. The broker understood our business needs. Would have liked a faster turnaround on the policy documents.

Reliable broker
Been with GrandMount Insurance Brokers for a couple of years now. They handle our home and auto insurance well. Sometimes hard to reach during busy periods.

Slow and unresponsive
GrandMount Insurance Brokers was very slow in processing my business insurance application. Emails went unanswered for days. Eventually I went with another broker.

Average experience
My experience with GrandMount Insurance Brokers was average. They found decent auto insurance rates but nothing spectacular. Communication could be improved.
