Planning rates only. Pick a currency — badges, inputs, and totals follow. Material is a rate. Labour is hours × a planning hourly rate. Equipment and delivery are this-job amounts.

Planning defaults are office figures, not a bid. US ready-mix in 2026 often lands around $125–165 per cubic yard delivered; place-and-finish commonly $2–4 per square foot. Replace every rate with a supplier or crew quote before you send the letter.

How this calculator works

A transparent caulk and sealant takeoff.

Joint run divided by the linear coverage of one cartridge at the bead you will gun, plus a visible start-stop allowance, rounded up to whole tubes.

Worked example. Example: 80 ft of joint at 50 ft per tube with 10% waste rounds to 2 tubes.

1. Add every joint you will tool: tub, window, siding, trim.
2. Enter coverage for YOUR bead. A 1/4 in bead and a 3/8 in bead are not the same tube.
3. Color and product (silicone, polyurethane, latex) are SKUs, not this count.

Questions

Questions about caulk and sealant

10.1 oz or 20 oz sausage?

Change coverage per tube to match the pack. A sausage often covers roughly double a 10.1 oz cartridge at the same bead.

Does this include backer rod?

No. Backer rod is a linear takeoff of a different diameter.

What is the formula ID?

This calculator publishes formula GEN-CLK-001, version 1.0.0. The ID stays on the result and on the estimate line.

Is this engineering advice?

No. Construclytic is a planning website, not a registered engineering or contracting firm. Field checks, codes and product data still sit with you.

Does Construclytic fetch live supplier prices?

No. Costs use the rate you enter. Construclytic does not fetch live supplier prices.
