| Build | Job cost | Labor | Crew hours | Materials | Illustrative selling price |
|---|---|---|---|---|---|
| A. Egress window in a poured wall | $6,840 | $3,324 | 34 to 46 h | $2,216 | $8,891 to $13,679 |
Dump fees and other costs ($1,300) are the same in every build and included in the job cost. Materials include allowances. Illustrative selling price is the job cost at a 30% to 100% markup; your price depends on your own overhead and profit. Labor hours are a planning range and include setup, daily cleanup and material runs; they are never a charge to the customer. Permit and inspection fees are not included; requirements vary by jurisdiction.
The build in detail
A. Egress window in a poured wall: $6,840
About four cubic yards of excavation, a saw-cut opening in the poured wall, a code-size window, a well with ladder and cover, gravel tied to drainage, and an insulated, trimmed interior return. Labor is $3,324 of the $6,840 job cost, or 48.6%. It is about 34 to 46 hours of work, including setup, daily cleanup and material runs.
Labor cost by trade
Labor only. Materials, allowances and dump fees are in the line items below. Hours are person-hours at typical production from Clamp’s labor hours catalog, as a range: a planning figure, not a schedule and not a charge to the customer.

Every line item
Labor $3,324 + materials and allowances $2,216 + dump fees and other $1,300 = $6,840 direct job cost. Hours are person-hours at typical production, on labor rows only, and the direct-cost row adds about 15% for setup, daily cleanup and material runs; an allowance or material row names the labor line that installs it, and a subcontract row has none, because the sub’s price includes their own time. Some labor quantities include a difficulty factor, so they can exceed the measured area; each row’s derivation is in the downloadable data.

Methodology & reproducibility
One reviewed snapshot for this build. The build is frozen from its own estimate run and priced by the published pricer.
Direct cost equals the sum of each row’s rounded quantity × (labor + material + other). Amounts are shown in whole dollars; every column adds to its total.
Scope selection, prose accuracy, arithmetic and provenance mapping reviewed; not independent market-rate verification.

Questions
What makes an egress window expensive?
The concrete: saw-cutting a poured wall, the equipment to do it, and four cubic yards of excavation are $3,324 of labor plus rental days before the window itself. The window, well, ladder and cover are the rest.
Does this make the basement room a legal bedroom?
It provides the code egress opening. A legal bedroom also has ceiling-height, smoke-alarm and other requirements that are finish work, which this build excludes.
What can change the price?
Block walls cut differently than poured; a deeper opening means more excavation and a taller well; and drainage that cannot take the well drain needs its own solution, priced when found.
