(Fortune Magazine) -- Call your agent and make sure that your coverage has kept pace with the times. With construction costs up 50 percent in some areas, many homeowners have become instantly underinsured through no fault of their own. The coverage to ask about: guaranteed replacement cost - which promises to pay the full cost of rebuilding your home if it is completely destroyed.

"Most carriers have an inflation guard," says Matthew Cullina, product manager for MetLife (Charts) Auto & Home. "But it doesn't keep up with the increase in construction cost." A contractor in your area should be able to tell you the average cost per square foot for renovation or new construction. Use that to estimate the cost of recreating your house. (Your agent can help too.)

Ask also about ordinance or law coverage, which covers the cost of bringing your home up to code in the event you need to rebuild or repair; that's not included in most standard policies.
