We're turning homes into Castles

“Castle is our go-to for all things home. They took away the headache and general confusion of managing the paperwork and filing for our historic and energy efficiency credits, helping us avoid a time suck and turning the experience into a seamless process (while finding us thousands of dollars we didn't realize we qualified for!). Paying for our home expenses has been a breeze as well; all the entities who still rely on checks (utilities, local/state/federal tax payments, and contractors) are sent a check through Castle and you will find the charge on your credit card! Voila!”

“We have loved using Castle during our home renovation. The Castle team has already identified more than $50,000 in credits that we qualify for, and have made the process of claiming those credits simple and easy. We now pay for all of our renovation expenses through Castle.”
