Common questions

Frequently asked questions.

Are the calculator results quotations?

No. Results are arithmetic summaries of the amounts you enter. Obtain written itemised quotations from appropriately licensed contractors.

Why use both low and high allowances?

A range makes uncertainty visible while scope, access and concealed conditions remain unresolved.

What should contingency cover?

Contingency is a planning allowance for uncertainty, not permission to proceed without investigation. Major unknowns should be assessed before purchase or work.
