Rich P.

We contacted Sentry Builders for our RV garage last November. We quickly received a quote and signed on the dotted line. It was a turn key building. They handled obtaining the permit and scheduling inspections. Their contract detailed when things would happen and when payments/draws would be due. Communication was awesome through every step of the process. Their employees were always there when they were supposed to be and were polite and professional. The building is done and it’s just perfect. Don’t hesitate to have Sentry build your steel building!
