THE NUMBERS
What goes into a project estimate?
Understand labor, material allowances, contingency, exclusions, and the difference between a planning range and an agreed quote.
A useful number needs a useful scope.
Two estimates can be far apart because they describe different jobs. Before comparing totals, compare what is being built, repaired, removed, protected, and finished. A lower figure is not automatically a better value if important work is outside it.
An online estimate is earlier in the process. It helps test a rough idea against a planning range. A site visit, specific selections, and an agreed written scope provide the detail needed for a project-specific quote.
Labor is more than the visible installation.
A labor allowance begins with the expected hours and an hourly rate. Preparation, access, protection, assembly, installation, and finishing can all affect time. Two rooms of the same floor area can require very different amounts of work.
The Crisfield calculator multiplies project size by a low and high labor-hours allowance, adjusts for complexity, and applies a minimum number of job hours where relevant. It then uses the configured hourly rate. These are broad assumptions for discussion, not a measured quantity takeoff.
Materials are an allowance until selections are specific.
A material allowance is a budget for a category of materials rather than a promise about a particular product. Size, specification, waste, lead time, delivery, and availability can change what a selection costs.
In the calculator, practical, considered, and premium finishes multiply the base material allowance by 1, 1.3, and 1.7. They do not name a brand or guarantee a specification. For an actual quote, ask which products are fixed, which remain allowances, and how a change in selection will be handled.
Contingency is room for uncertainty.
The planning reserve is a percentage of the labor and material subtotal. It makes some uncertainty visible. It does not mean every unexpected condition is included, and it does not make the upper end of the range a guaranteed maximum.
Concealed conditions can change the work after a surface is opened up. Discuss how discoveries will be documented, priced, and approved before extra work proceeds. A clear change process matters as much as the starting figure.
Read the exclusions as carefully as the total.
The online range excludes permits, design and engineering, taxes, specialty trades, site preparation, and concealed conditions unless specifically agreed. This is especially important for new construction, where site conditions and professional services can be a substantial part of the overall budget.
The displayed calculator total rounds the low end down and the high end up to the nearest ten dollars. Breakdown rows are displayed to the nearest dollar. Neither the formatting nor the detail changes the preliminary nature of the result.
Bring better inputs to the first conversation.
Share the approximate area, the current condition, what you hope to keep, and whether the layout will change. Note any access constraints and any timing preferences. If you already have drawings or selections, mention them.
Before committing, ask for scope, allowances, exclusions, schedule assumptions, and payment terms in writing. The goal is a number with enough context to make a useful decision, rather than a precise-looking figure built on unknowns.
