A whole-house renovation estimate is a different document from a single-room quote. It has to cover work that cannot be fully seen, trades that depend on each other, and a schedule long enough that material prices and availability move within it.
A good one is therefore explicit about three things: what is included, what is assumed, and what happens when an assumption turns out to be wrong. Anything that is vague on those three will change.
What a real renovation estimate contains
A scope written room by room in actions rather than adjectives. "Remove existing flooring, assess and level subfloor, install client-selected engineered flooring with underlay and perimeter expansion" rather than "new flooring throughout".
Allowances stated with their per-unit figure. Flooring at a stated dollars per square foot, tile at a stated rate, lighting at a stated budget. Allowances are legitimate and necessary at estimate stage; hiding them is not.
Written assumptions about what cannot be seen: the condition of the wiring, the supply plumbing, the subfloor, the insulation and whether specific walls are load-bearing. On an older house this section is the most important part of the document.
A payment schedule tied to completed stages, a written change order process, and a stated contingency or a clear statement that contingency is the homeowner’s to hold.
What moves the price
- How much investigation happened first. An estimate produced after opening a few inspection points is worth far more than one produced from a walkthrough.
- Allowance levels. The single largest source of apparent difference between competing estimates.
- Whether design is included. Some estimates include design and drawings, some assume you arrive with them.
- Schedule length. A twelve month project carries more price risk on materials than a three month one, and good estimates say how that is handled.
Mistakes we see most often
- Comparing estimates on the total without comparing the allowances and assumptions inside them.
- Accepting an estimate for an older house that contains no written assumptions about hidden conditions.
- Paying a large up-front deposit not tied to progress.
- Treating the lowest number as the best value without establishing what it excludes.
What this means in the Capital Region
For a whole-house project in a pre-war Capital Region home, we would expect to open a small number of inspection points before giving a fixed price: a section of plaster to look at the framing and wiring, access to the waste stack, and the panel. It is a couple of hours of work and it is the difference between an estimate that holds and one that moves at demolition.
Our estimates are free and written, and they state the scope, the allowances with per-unit figures and the assumptions. If you are comparing us against another contractor, comparing those three sections will explain any difference in the totals far more reliably than the totals themselves.

Frequently asked questions
How long should a renovation estimate take?
One to three weeks for a whole-house project, depending on size and how much investigation is needed. A number produced on the first visit without measuring is a guess.
Should I pay for an estimate?
Not for the estimate itself. Mastaba provides written estimates free. Detailed design work, drawings and engineering are separate services and are reasonably charged for.
Why are two estimates so different?
Allowances, inclusions and assumptions, in that order. Ask both contractors for the per-unit figure behind every allowance and for their written assumptions about hidden conditions.
What if you find something unexpected?
It is priced as a written change order and agreed before the work is done. That process should be in the contract, and you should never first learn about extra work on the final invoice.
