"April helped us line up a last minute inspection for a new build for us. They were extremely thorough and found a few significant problems that we were able to take to the builder. They included lots of photos of the issues which was helpful. They used thermal imaging too which was new to us but helps detect problems that may not have been seen otherwise. We got our report along with a summary the next day and had excellent communication and follow through. We will definitely use them in the future and highly recommend."
