Personally never let my home owners insurance go up without a fight. This year, called them and the said the price of lumber and other building materials had gone up so much they had to increase the coverage to cover the extra $69,000 bucks or so.
Told them no way - our house is built like a bunker with cement and rebar - wouldn't need all that lumber - they decreased it.
I think a lot of folks are over insured. In any "stick house" fire you are always left with the slab, driveway and land - there is
never a 100% burnout coverage needed. This year we got our car insurance reduced by 10% also due to lite mileage every year.
Gotta talk to them...squeaky wheel gets the grease. Learned that from an insurance agent...lol.
