A number you can explain

Every line shows quantity, unit, unit cost and total, grouped by CSI division: concrete and foundations, framing, roofing, windows and doors, drywall and finishes, plumbing, HVAC, electrical and sitework. When a homeowner asks what's driving the price, you can show them.

The estimate also lists assumptions and exclusions written for the job, such as which finishes were assumed where the plans don't say, or which items the owner is supplying. That gives you a clear list of what the number includes and what it doesn't.

Your markup stays yours

Overhead and profit, contingency, and bond and insurance are separate lines, not buried in unit costs. Set them to match how you run your business. The spreadsheet is editable, so you can plug in your own subs' numbers and supplier quotes.

When material prices keep moving

In the July 2026 NAHB/Wells Fargo Housing Market Index survey, builders reported a median 6.7% annual increase in material costs for the same house, and 9.1% for builders with five or fewer starts (NAHB Eye on Housing). Each Datum estimate is priced for 30 days from the date it's prepared and carries a confidence range on the total, so you can decide how much contingency to carry.

What to send

  • Plans (PDF or DWG), including any structural drawings
  • Specs or a finish schedule, if you have one
  • Photos of existing conditions for remodels and additions
  • A description of the scope, exclusions and anything owner-supplied
  • Your target price and bid date, if you have them

Missing something? Send what you have. When the set has gaps, we email you questions, and if we can't estimate from what you sent and you can't provide what's missing, you get a full refund.

Price and turnaround

One flat fee from $129, set by project value. We aim to confirm your files within one business day of payment. Delivery is within 3 business days after that, or within 24 hours for a flat $149 more. See all prices and what each tier includes.

Each estimate is an opinion of probable cost, not a bid or a guaranteed price. You check it and build your own price from it.
