AStrata work is a gravy train.
The fire inspector has a monopoly on your property. You need him to sign off the AFSS.
Even if you get someone else to do the repair, the fire inspector has to retest, for which he will charge you.
If you feeel you are not getting the best deal, go out to tender for your fire inspections.
And the issue of findingnew defects each year is not uncommon. If the committee does not monitor and question these defects you will always be paying . Unfortunately the fire regulations are complex, so find a fire inspector you can trust.
