Welcome to the New Minnesota Lath and Plaster Bureau 

Yes there have been a few changes: Office operations have been suspended and you can no longer pick up the phone and just give us a call. We remain however in an on-line presence. We will continue to work to bring you relevant industry information. If you have a simple question just shoot us an e-mail. If it is more than just simple, we will forward it on to someone that can help.
