Insurance By Castle
At Insurance by Castle we specialize in landlord, rental property, and apartment insurance - but can write for nearly any personal or commercial policy. Our "5 Doors or More Program" is specially designed for landlords who own 5 or more rental properties. This is an exclusive program that no other insurance agency offers.

For over 30 years, Insurance by Castle has been providing comprehensive landlords, rental property, and apartment insurance in Redwood City, San Mateo, and surrounding areas throughout California. Our customers come to us for the price, but stay for the exceptional customer service we provide to each person that walks through our door.
Services
Three generations of the Castle family have built Insurance by Castle from a one person business serving local community clients to a leading insurance provider in California. Today, Insurance by Castle provides a wide range of insurance services to a variety of clients, including both businesses and individuals.
Insurance by Castle specializes in providing apartment owner's insurance in California. Our customized policies are tailored to your needs to guard your assets against accidents, peril, lawsuits, and loss of income. Insurance by Castle has a long record of exceptional customer service (with over 500 5-star reviews) -in fact, we've been in business for more than three decades.
If you're like many Americans, your car is probably like a second home. You rely on your vehicle to get you to work, pick your children up from school, and run errands. On average, Americans drive 220 miles per week, adding up to almost 12,000 miles per year. That's the equivalent of driving from Washington D.C. to San Francisco twice.
Your home is one of the most significant investments you'll ever make. Whether you're settling a mortgage or paying monthly rent, you want to protect the place you inhabit - and the people and property it shelters. Insurance By Castle provides comprehensive home insurance coverage so that you can rest easy.
If you opt to rent instead of own your home, you aren't alone. California's homeownership rates are on the decline, and the state overall has a lower rate of homeownership compared to the national average. As a renter, it's essential to protect your home and yourself with comprehensive renters insurance.

I currently have several types of insurance policies with Castle Insurance including rental/personal properties, automobile, and umbrella that I am confident I am getting a very fair value. The crew at the office is always responsive to my matters. I have only filed one claim on a rental property and it was resolved promptly. I always refer my friends and clients to Castle Insurance for I am confident that they be provided with quality service.

Theses people are a waste of time, I spent 30 minutes submitting all the information they require for 13 of my 25 properties on their website, the next day they say they only have 1 competitive company for Manufactured homes and completely disregarded the other properties I submitted. When I asked if they'd quote the properties that were not Manufactured they asked me to resend all the info again... NO THANK YOU YOU HAVE WASTED ENOUGH OF MY TIME...
P.S. The broker I currently have has 4 companies that are competive for manufactured homes...

Why are we with Castle, simple answer.... because you guys are ALWAYS there for us. We have an issue, you solve it. We call, you answer. We need something, you get it. You’re whole team is GREAT! No weak players, everyone in the right seat. We also love how you stay out in front of us, adjusting policies, looking for better pricing, making sure we have what we need. Renewing with Castle is the easiest decision we make all year!

I like the combining 7 units together and receiving a better rate. Insurance costs are important when owning apartments. We also like your easy service.
