ONE PROBLEM, IN DETAIL

COLD WEATHER CONSTRUCTION JOB COST: COLD WEATHER AND THE MORTAR CLOCK

QUICK ANSWER

Mortar cure has temperature floors. Winter work means heated enclosures, ground thawing, admixtures, and slower rates, or it means idle crews. Northern contractors either price a winter premium or eat one.

This page covers one problem. The full picture for this trade, including the other places margin leaks, is on the masonry operating system page.

Sourced framing

cold-weather masonry requires "heated enclosures, ground thawing, and slower mortar cure times when cold-weather masonry can't be postponed." (NEDES estimating guide, 2026)

WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

Masonry contractors run about % net profit at $1M to $5M, rising to roughly 9% at $5M to $10M. The CFOS target at $1M to $5M is10%, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.

Gross margin over the same bands runs % to 22%, against a CFOS target of 10%.

COMMON QUESTIONS

FREQUENTLY ASKED.

Give winter work its own cost codes (enclosures, heat, admixtures, thaw time) and either bid a winter premium or document the delay for compensation. The mortar clock doesn't negotiate; the only choice is whether the cost is priced, claimed, or eaten.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
Sixty days. We migrate your books back to the start of your last taxable year, set up ControlQore, and build your job costing structure from scratch. Fully operational in two months.
