Built one course at a time

Masons lay a wall one course of brick at a time, and each course sits level on the one below. We build Tallmason the same way: one client, one estimate, one checked quantity at a time.

Our story

Contractors lose bids for a simple reason. They do not have the hours to estimate every job that comes in. Good estimators are hard to hire, and a bid date does not wait.

Tallmason gives those contractors an estimating team on demand. One founder finds and serves the clients. One experienced estimator does the takeoffs and the pricing. The two of us check every estimate before it leaves.

We incorporated Tallmason in Delaware in 2026. You speak directly to the people who do the work, from the first call to the final number.

How we work

Measure, then price

A price is only as good as the quantity under it. We measure first.

Show the work

Every estimate comes with marked-up drawings. You can trace each number to a sheet.

Keep the date

The bid date does not move. We agree a delivery time and we meet it.

Say what is missing

When the drawings leave a gap, we write it down as a clarification. We do not guess in silence.
