Here is the question almost nobody asks before signing, and it decides whether the number you are given is the number you pay.
How many allowances are in this price?
An allowance is a placeholder. The agreement carries $9,000 for cabinets before anyone knows which cabinets. It looks like a price. It is a guess with a dollar sign on it, and when your selection lands above the guess, the difference comes back to you as a change order, after you are committed and after demolition.
We do not use allowances. We do not use contingency funds either, for the same reason: a pre-agreed pot of money for unknowns quietly removes the pressure to plan completely, and shifts the cost of incomplete planning onto you. A kitchen involves somewhere between 60 and 150 individual selections across more than 30 categories. We price every one of them with you during design, before there is an agreement to sign. That is what makes a fixed price fixed.
Three more commitments, in writing, because you should be able to ask any remodeler for the same four:
We absorb our own errors. If we get something wrong, it never arrives as a change order.
Found conditions are disclosed the same day we find them. Not at the weekly meeting, not at the end.
A change order carries a photograph of what we found, the solution, the price and your revised project total. Ours typically run $2,000 to $5,000 when they happen. You can read exactly what a change order is and when we write one.
Ask the three firms you are considering those four questions. How the answers come back will tell you more than any estimate will.
