Clear View Plumbing And Heating

I noticed that one of floor bolts was loose, when I checked why it's loose I found that part flange ring is broken and not keeping this bolt. I called ClearView, their guy came in and said that he can fix it and he just need to prepare estimate. His estimate was 700CAD for simple job and even he agreed that it's maximum 2 hours in worse case.
P.S. I'm leaving in almost new house, so it's not old rusty flange or case when you need to drill concrete.
