 Trustindex verifies that the original source of the review is Google. I am more than satisfied with the service I received from Castleworks Home Services.  From taking my phone call after hours when I discovered that my water heater was broken and leaking, and scheduling an appointment for the very next day… to keeping me updated on the estimated arrival time of my technician including a text with his full name and photo ID was truly impressive.  But what was even more impressive is the actual service itself.  Justin, the technician, was extremely easy to work with.  He was knowledgeable, polite, explained everything, answered all of my questions, and completed all of the work in one visit.  I couldn’t ask for a better experience and highly recommend this company! 5 ⭐️⭐️⭐️⭐️⭐️

 Trustindex verifies that the original source of the review is Google. We have just had 2 excellent experiences with Castleworks. Picked up the phone right away and was great with communication via phone and text to keep us informed as to when our technician would be out. And Justin the technician himself was absolutely amazing. Knowledgeable, worked clean and quick. We had such a good experience we ended up calling them back out right away for another issue with A/C that was long overdue and had another great experience with Brendan. So hard to find reputable companies that do what they say and that you can trust. Fully recommend them. Save their number!

 Trustindex verifies that the original source of the review is Google. James Skresvig went above and beyond for me. He even changed a hose for me, completely unrelated to the job he came to do, just to help me out because I didn't have the right tool. He answered all of my questions and was very good at explaining their services without overselling anything - more like explaining options.
