How Do You Keep Construction Estimates Accurate??

Man, these material prices are getting crazy. Every time I make an estimate, the cost changes before the job even starts. One week it’s steel, next week it’s lumber. It’s hard to keep numbers steady anymore.

I’ve started adding a little extra in my quotes just to be safe, but even that doesn’t always work out. Talked to a few construction estimators and everyone’s got their own way of handling it. Some update prices every week, others just roll with it. What’s working best for you guys?
