When people ask what extended warranty company we have for our RV and are we happy with them? We tell them Cornerstone United Inc. & Yes we are pleased with you. Thank You!

We have had 3 major failures in less than 2 months. First the inverter failed and had to be replaced. This was a top of the line Magnum and just the inverter cost 2800 bucks. Two weeks later the refrigerator stopped cooling. The cooling unit had to be replaced. After the cooling unit was replaced the power board failed. Next the gas valve failed. After the fridge was repaired 3 of the 4 slides stopped working. two controllers and one motor. CornerStone stepped up to the plate on every failure. I will be asking for a renewal contract once this one expires we simply could not have survived with out CornerStone! I highly recommend CornerStone United Inc.



On a trip travelling out west we encountered some issues that needed to be repaired right away. I contacted Cornerstone , told them of the situation and they immediately approved the repairs. They were completed in a timely manner. Thank you Cornerstone for your quick and professional responses

Completely hassle free. That is wonderful when dealing with warranties. It was great that we were able to use a local mobile service for our repair. No complaints.



I'm happy. So far I've had to file two claims. The first one was made simple by the rep I spoke to. She gave me all the necessary paperwork and explained what needed to be done. The second one was even simpler because I already had copies of the necessary paperwork. I'm glad that I bought this warranty.



Our claim was handle with care and speed. No problems at all. Great to work with ! Thanks for the great response to our claim.

We needed unexpected work done on our rig and Cornerstone came through for us! Any time we have needed warranty work done they have never denied our claim! We will continue to do business with this company!

I bought this policy when I purchased my bike. Luckily, I haven’t had a need to use it. I took my bike in for service last month as it was throwing codes then nothing. It ended up being the switch that was faulty. The repair was done and the policy covered the all the repairs. I am over the moon satisfied with my purchase of this policy.

So easy to work with and so quick to get claims completed. Thank you

My mechanic called Cornerstone with the issues involved on my 2008 Dodge Ram and both were approved immediately. A very quick response got my truck back on the road in a day. It also helps to know what your warranty covers and what it does not cover to prevent delays. Thank you for being there when needed.



When I called on how to file a claim, the polite staff informed me how to file. After I filed a claim, it was processed quickly.
