"The inspectors were just here and I have our 'Certificate of Completion'. One of them even asked me who did it because they said it looked fantastic and whoever did it did an excellent job! So, I gave him the info. They said everything looks great, so I guess the project is officially complete. Thank you for everything! We are so happy with how everything turned out. We are already getting compliments from our neighbors, so if anyone asks I will definitely be referring them to you!!! Please be sure to thank Mike, Constantine, and the rest of the team for us."
