They were able to fit me in on short notice and did an excellent job cleaning a very dirty apartment. They stayed until the job was done and it came out better than the day I moved in.

Thank you so much for this review! ✨ We're so glad we could fit you in on short notice and that the team stuck it out to get the place looking even better than move-in day - that's exactly the kind of result we aim for. Thank you for trusting Cornerstone! 🏡

I had a great experience with Cornerstone Cleaning. Communication was easy from start to finish, and they were responsive to my questions and scheduling needs.
I hired them to clean one bedroom, one bathroom, and the carpet, and the pricing was very reasonable for the quality of service provided. They also followed up after the cleaning to make sure everything met my expectations, which I really appreciated.
Overall, I'm happy with the service and would definitely recommend them to anyone looking for a reliable and affordable cleaning company.
