“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!”
