How to Price Crack Sealing Per Linear Foot (With the Math)

Crack sealing is priced per linear foot of crack, and the rate comes from the pounds of hot pour the cracks take, the hours spent cleaning and sealing them, and the margin on top. Here is how to price crack sealing per linear foot from a measured length, a coverage chart and a published wage, worked through on a 1,500 linear ft lot, for sealcoating crews and lot maintenance teams.

Why crack sealing is priced per linear foot

Crack sealing is priced per linear foot because sealant and labor both scale with the length of crack, not the area of the lot. SealMaster's cost FAQ lists footage, severity, prep, filler type and region as what moves the price, and puts typical crack sealing at $0.35 to $1.00 per linear ft.

Step 1: Measure the cracks

Measure every crack you intend to seal in linear feet, with a wheel on site, a sample section on a big lot, or a satellite trace for a bid sent before the visit.

• Measuring wheel: walk every crack and note widths as you go.
• Sample section: wheel one section of an evenly cracked lot, scale it to the lot's area, and walk the worst spots separately.
• Satellite trace: wide cracks show as dark lines, hairline cracks do not, so trace what shows and confirm on site.

The free satellite measurement tool traces a line along each crack: tap the points, then double-tap or click Finish line; more lines sum into one length. In MakeHay, the saved measurement fills a Per linear foot quote line's quantity and updates if you edit the trace (measure a property from satellite).

Tip: Write the width next to each length; Step 2 needs feet by width, not one total.

Step 2: Classify by width and depth, and when backer rod is needed

Sort the footage into three classes, 3/8, 1/2 and 3/4 inch, the widths the coverage charts are laid out by, and set anything wider aside for a different repair.

The Minnesota Department of Transportation's Crack Sealing 101, a US state guide, routs and seals transverse cracks up to 3/4 inch wide, cleans and seals longitudinal cracks without routing, and sends a pavement in poor condition to mastic or patching.

Depth matters as much as width: both charts assume depth equal to width, and Minnesota's standard rout is 3/4 by 3/4 inch, so a deeper unrouted crack swallows sealant you did not count. Backer rod is for a crack deeper than it is wide: the US FHWA checklist lists it as a material check (compatible with the sealant), and the rod gives the hot pour a floor at the depth the chart assumes instead of letting it sink. Price rod by the foot as its own line.

Step 3: Hot pour crack filler coverage from the maker's chart

Convert feet to pounds with the manufacturer's chart: feet in each width class divided by 100, times the pounds per 100 ft for that width, summed and rounded up to whole 30 lb boxes. Both SealMaster pages call the rates a guideline.

Asphalt Kingdom's 6.7 linear ft per lb sits between the charts' 1/2 inch and 3/4 inch rows: a sanity check on a mixed lot, not the estimate.

Minnesota's guide says to avoid wide, thick overbands and SealMaster's repair FAQ wants a thin band on each side; a heavy overband is the usual reason a job uses more pounds than the chart says. Price the pounds at what you pay: on October 12, 2026 Asphalt Kingdom's page for its hot pour rubberized crack filler showed $408 for the three-box minimum order, which is $136 per 30 lb box, or $4.53 per lb.

Step 4: Labor and the production rate to track

Labor per foot is your crew's hourly cost divided by the feet they finish in an hour, a rate nobody can publish for you. Track it on every job, with hot pour, cold pour and routed days logged separately.

Count the cleaning hours. The US FHWA checklist wants each crack blown clean, checked with a finger along the sidewalls and recleaned if dirt is found, with cleaning kept just ahead of sealing.

For a wage to start from, O*NET's profile for highway maintenance workers, built on US Bureau of Labor Statistics 2025 wage data, lists a median of $24.16 per hour. Add payroll taxes and insurance; the example uses the bare median.

Step 5: Minimum charge, mobilization and margin

Set the minimum at half a day plus one box, divided by one minus your margin, and carry it as a flat line whenever the per-foot total falls short.

Mobilization is real cost: the melter has to reach Asphalt Kingdom's heating range of 380 to 400°F before the first foot goes down, so a small lot pays the same warm-up as a large one.

Margin is the last step: price equals direct cost divided by one minus the margin, and the rate is that price divided by the feet. Check it against SealMaster's $0.35 to $1.00 per linear ft; above is fine when the quote shows the width classes that drove it; below is a sign to look for a cost you left out.

How to bid crack filling on a 1,500 linear ft lot

The lot measured 1,500 linear ft: 900 ft at 3/8 inch, 450 ft at 1/2 inch and 150 ft at 3/4 inch. Coverage comes from the CrackMaster Supreme DF chart; the box price is Asphalt Kingdom's $136 per 30 lb box of its own hot pour filler, standing in for what you pay; labor is two people for one 8 hour day at the O*NET median, which assumes the pair cleans and seals about 190 ft an hour (1,500 ÷ 8) with the melter warm-up inside the day; and the target is a 40 percent gross margin. Swap in your own logged rate.

The rate lands above SealMaster's typical range for two reasons: the 150 ft of 3/4 inch crack takes 37.5 of the 143 lbs, a quarter of the sealant for a tenth of the footage, and the boxes are priced at the three-box retail minimum rather than in bulk. A lot of hairline cracks only, priced from the 3/8 inch row, lands lower.

When to crack seal before sealcoating: spring or fall

Seal cracks in spring or fall on dry pavement, and before the sealcoat: the sealer goes over filled cracks, and Minnesota's guide says crack sealing is what keeps moisture out of the base and subgrade.

Minnesota's guide recommends spring or fall in dry conditions, when a crack is neither at its widest (winter) nor its narrowest (summer), and SealMaster's repair FAQ puts the ideal air temperature at 45 to 65°F where winters are cold. SealMaster's sealcoating how-to lists filling cracks as a step before the sealer and wants at least 60°F and rising for the sealcoat. A fall crack sealing visit sets up a spring sealcoat, priced with how to price sealcoating per square foot and checked against sealcoating temperature requirements.

In MakeHay, a weather rule on the crack fill service sets Max rain % and Min temp °F for the visit, with the forecast from the National Weather Service for each job site's own address (US job sites); see plan around the weather.

Hot pour versus cold pour

Hot pour is the production choice for roads and most lots; cold pour is for driveways. SealMaster's repair FAQ puts hot pour on highways, both on parking lots and cold applied material on home driveways: hot pour goes down as low as 40°F and cools in 15 to 20 minutes, while cold pour wants warm, dry weather and 24 hours of cure. Hot pour also needs the indirectly heated double boiler melter the US FHWA checklist calls for. Price them as two services.

What to put on the crack sealing estimate

Put the measured length, the width classes, the rate and the minimum on the quote, so the customer sees what was counted and what more footage costs.

• Linear feet measured, and how: wheel, sample section or satellite trace.
• Width classes with the feet in each, so a wider crack found on the day is a change order.
• The sealant by name, routed or clean and seal, the rate, the mobilization line and the minimum.
• When the lot reopens, and that any sealcoat comes after.

In MakeHay, the sealcoating starter price book carries Hot-applied crack fill as a Per linear foot line, the line striping list carries Crack fill the same way, and a flat Mobilization and lot prep line covers the minimum. Set This job repeats to every 12 months and the lot comes back each spring (set up recurring service).
