(ME calling him ONLY) Then after, ME CALLING HIM several times for photos and bill. It’s been 20 days with no follow-up, no callback, and no update. I honestly don’t even know if the job was ever done. Very poor communication and unreliable service. I DO NOT recommend engaging them.

Allstar team led by Wein was able to traced where the source of water leakage and did solved & repaired the water leakage effectively within a short time. In June 2024, I approached Wein if Allstar was willing to patch up cracklines in walls and then paint the whole house. Though mere pa

He gave me a fair quote and his workers carried out the job promptly and were polite, tidy and professional. Since then Wein has done 2 other jobs for me for another part of the roof. I fully recommend this company for waterproofing issues👍👍👍
