Frequently asked questions

Are these starting values recommendations?

Worked example: from items to total

With the fictional starting values: removal EUR 200, painting EUR 600, flooring EUR 800, plumbing EUR 350 and electrical work EUR 500. Materials are EUR 1,070 and labour EUR 1,380. Adding EUR 100 fixed costs gives EUR 2,550. A 10% contingency is EUR 255: EUR 2,805 total with the entered tax at 0%. This is not a market rate or a quote for a specific home.

What is included and what may be missing

Only selected items and entered amounts are included. Permits, professional fees, waste disposal, kitchens, bathroom fittings, furniture, transport and concealed work are not added automatically. Include them in other work or fixed costs without duplication. Request comparable quotes and verify measurements and scope with the contractor.

How to measure each item

Do not use floor area as wall area. Enter the actual surface for each item and use “job” for a fixed-price intervention. Contingency is editable and does not guarantee all unexpected costs are covered.
