The Manteca Post Office on the southwest corner of Center Street and Maple Avenue in downtown Manteca is getting a well-deserved facelift.The aging tile roof is being replaced, and the outside walls are receiving a fresh coat of paint.It’s business as usual at the post office while workers with FH Paschen contractors try to finish the job in two weeks, said Postmaster Jennifer Gowans. Work on the project started about two weeks ago.“We are replacing the roof because the tiles were the originals and they were cracking and we are starting to lose them in the weather. They were starting to fall.
