## Calculator questions

How accurate is this crawl space calculator? It gives a range built from real Wilmington-area price bands, and it is accurate enough to tell you whether you are looking at a $5,000 or a $12,000 job. It cannot see your clearance, your water table or your framing, which is why a free on-site measure is still worth an hour. What is the biggest cost variable? Drainage. A crawl space needing a perimeter drain and sump adds $1,500 – $5,000 to an otherwise straightforward encapsulation, and it is the single largest swing in almost every quote. Why does clearance change the price? Below roughly 24 inches everything is done lying down. The same square footage takes considerably more labour hours, and material has to be dragged rather than carried. Does the estimate include a warranty? The estimate is for the work. What is warranted — material, workmanship, or a performance outcome — is set out in the written quote, because those are three different things.
