Crack sealing calculator: sealant, boxes, crew time and price
The cracks
Your prices
Sealant is taken off the way FHWA's crack seal manual does it: the crack's cross-section plus the band, at the sealant's weight, plus 15% waste. Contractors bid $0.50-$3.00 a foot; band-over work runs $0.80-$1.50 and routed work $1.50-$2.00. Sealant by the pallet is about $0.95-$0.98 a pound; a single 30 lb box is $136.

How much does crack sealing cost?
Bid it by the linear foot, on its own line. Contractors charge $0.50-$3.00 a foot: $0.80-$1.50 to clean and seal with a band, $1.50-$2.00 when the cracks are routed first. Take the sealant off by the pound: 550 ft of half-inch cracks is about 140 lb.
How to Price Asphalt Crack Sealing
Four numbers make the bid. The footage comes off a measuring wheel; everything else follows from the size of the cracks and the equipment on the trailer.
Sealant a foot
(crack + band) sq in × 12 ÷ 231 × 9.76 lb/gal + 15%
(0.250 + 0.188) × 12 ÷ 231 × 9.76 × 1.15 = 0.255 lb

Price
linear feet × your price a foot
550 × $1.50 = $825
The 9.76 lb a gallon is a specific gravity of 1.17, from SealMaster's data sheet for its rubberized hot-pour. The 15% is the waste allowance in FHWA's worked example: sealant left in the kettle, the wand and the overfill.
Your price a foot carries the crew, the melter, the compressor or heat lance, fuel, overhead and profit, and the material at $0.15-$0.30 a foot by OneCrew's figure. The material is the smallest part of the line: on the example it is $147 of a $825 job.
Crack Sealing vs. Crack Filling vs. Patching
Not every crack takes sealant, and the ones that should not are where a crack sealing bid loses its warranty. The lines below are FHWA's and Caltrans'.
| Crack | Treatment |
|---|---|
| Hairline, under 1/4 in | Not treated: note it and watch itCaltrans treats cracks over 1/4 in; FHWA's low-severity band is up to 6 mm. |
| 1/4 to 3/4 in, moving with the seasons | Seal: rout, clean, hot-pour with a bandFHWA seals working cracks 5-19 mm wide that move more than 3 mm a year. |
| Up to 1 in, not moving | Fill: clean and hot-pour, no routFHWA fills non-working cracks 5-25 mm wide; movement, not width, decides. |
| Over 1.5 in | Mastic or a patch, not sealantCaltrans: wider cracks need specialty treatments such as mastic. |
| Alligator (fatigue) cracking | Dig out and patchA base failure. Caltrans recommends dig-outs at medium or high severity; sealing does not fix it. |
FHWA's manual makes movement, not width, the deciding test: a crack that opens in winter and closes in summer is a working crack and gets sealed, usually routed first; one that barely moves gets filled. It also warns that a lot with a large number of cracks, or severely deteriorated ones, is neither economical nor sound to seal. That lot is a paving bid.
How Much Crack Sealant per 100 Feet
Pounds of hot-pour per 100 ft of crack, 15% waste included, sealed flush and with the two bands the sources recommend. The last column is SealMaster's own chart, which counts the crack only, with no band and no waste.
| Crack | Flush | 3 in band | 4 in band | Maker's chart |
|---|---|---|---|---|
| 3/8 × 1/2 inunrouted, narrow | 10.9 lb | 21.9 lb | 40.1 lb | 8.3 lb |
| 1/2 × 1/2 ina 1/4 in crack, routed | 14.6 lb | 25.5 lb | 43.7 lb | 11.1 lb |
| 3/4 × 1/2 inwide, shallow | 21.9 lb | 32.8 lb | 51.0 lb | 16.6 lb |
| 3/4 × 3/4 ina 1/2 in crack, routed | 32.8 lb | 43.7 lb | 62.0 lb | 25.0 lb |
The band is most of the sealant. A 3 in band 1/16 in thick, Crafco's recommended overband, nearly doubles a half-inch crack's pounds; FHWA's worked example uses a 4 in band about 1/8 in thick, which triples them. A takeoff from a chart that leaves the band out runs short on the first lot.
The routed sizes are Caltrans': a 1/4 in crack routed to 1/2 × 1/2 in, a 1/2 in crack to 3/4 × 3/4 in. Hot-pour comes in 30 lb boxes, about $0.95-$0.98 a pound by the pallet and $136 for a single box from Asphalt Kingdom.

River Forest, IL to Sedgwick Co., KS, 2025 bids
The example prices at $5.89 a pound of sealant, above the municipal bids. Those contracts run tens of thousands of pounds across a whole road network, so the mobilization is spread thin. A single lot carries its own trip, its own melter heat-up and its own clean-up, and the price a pound should say so.
On the sealcoating pages the crack line is quoted at $1.00-$2.00 a foot: OneCrew's baseline up to routed work. Use the bands to check you are in the same market, not to set the number.
Crew Time, Weather and Service Life
Feet an hour of application, as the sources time it. Blowing out and drying the cracks comes on top, and a lot full of parked cars runs slower than a closed road.

The calculator uses 500 ft an hour for a hand-push melter and the low end of FHWA's range, 886, for a melter-applicator, and adds routing at 689 ft an hour when you tick it.
Seal at 40°F and rising, on dry pavement, with no rain coming: that is FHWA's checklist, and SealMaster sets the same floor for the air and the surface. The kettle runs at 350-400°F. Sealcoat needs 50°F, so crack sealing runs later into the fall than the coat it goes under. When the two share a visit, the cracks are sealed first and the coat goes over them.
FHWA's manual puts rubberized sealant banded over routed working cracks at 5-9 years, and over cracks that were not routed at 2.5-5 years. The routing is what the longer life costs, and it is why routed work is priced higher.
Worked Example: 550 Feet of Cracks
The 65-stall church lot from the sealcoating bid guide: moderate cracking, sealed six years ago, the cracks cleaned and sealed with a band before two coats go down.
Routed instead, the same footage adds about 48 min on the router and moves the line into the $1.50-$2.00 band. The sealcoat itself is priced by the square foot, on the sealcoating cost calculator.
Measure the Lot Before the Walk-Through
Crack sealing is rarely bid alone. The sealcoat it goes under is the bigger line, and that one comes from the lot's square footage.
Measure the lot
Search the address and trace the pavement on satellite imagery. That square footage prices the sealcoat the crack sealing rides with.
Walk the cracks
Satellite gives you the lot. The crack footage comes off a measuring wheel on the walk-through, logged by size.
Quote both lines
The sealcoat priced on the measured square feet, crack sealing as its own line (550 × $1.50), on one quote with your business name on it that the manager can accept online.
Where a Crack Sealing Bid Loses Money
The footage is the easy part. The losses are in which cracks you take and how you take off the sealant.
Sealing alligator cracking
It is a base failure, and sealant over it fails with it. Dig it out and patch it, and say so on the bid, or the callback is yours.
Taking off sealant without the band
A maker's chart counts the crack alone. The band over it is most of the sealant, and a takeoff that leaves it out runs short.
Folding the cracks into the sealcoat rate
Cracking varies more between lots than anything else. On its own line, at your price a foot, the customer sees exactly what they are buying.
Sealing wet or cold cracks
Below 40°F, or with moisture in the crack, the sealant does not bond. A cheap day becomes a warranty visit in spring.
Measuring the lot zone by zone is covered on the parking lot square footage calculator.
Crack Sealing Questions
Cost, sealant, which cracks, crew time and weather.
Contractors bid it at $0.50-$3.00 a linear foot, and OneCrew notes that many use $1.00 as a baseline. A facilities trade magazine puts clean-and-seal with a band over the crack at $0.80-$1.50 a foot and routed sealing at $1.50-$2.00. A lot with 550 ft of cracks at $1.50 a foot is $825, using about 140 lb of hot-pour sealant.
Multiply the crack's cross-section, plus the band laid over it, by the sealant's weight and add 15% for waste, the method in FHWA's crack seal manual. A 1/2 × 1/2 in crack with a 3 in band 1/16 in thick takes about 0.26 lb a foot, so one 30 lb box seals about 118 ft. Sealed flush with no band, the same crack takes 0.15 lb a foot.
Sealing goes into working cracks, the ones that open and close with the seasons, and is meant to move with them: FHWA's manual seals cracks 5 to 19 mm wide that move more than 3 mm a year, usually routed first. Filling goes into cracks that barely move, up to about 25 mm, without routing. The manual says movement, not width, should decide which one a crack gets.
Alligator cracking, the interconnected pattern that looks like a reptile's skin, is a failure of the base, and Caltrans says crack sealing will not treat it; at medium or high severity it recommends digging out and patching. Cracks wider than about 1.5 inches need a mastic or a patch. Hairline cracks under 1/4 inch are usually not treated at all.
It depends on the equipment. OneCrew puts a hand-push melter at 400-600 ft an hour and work by hand at about 100. FHWA's manual times a melter-applicator at 886-1,575 ft an hour of sealing and a rotary router at 689-886. At 500 ft an hour, 550 ft is about 1 hr 6 min of sealing, and 1 hr 54 min with routing.
FHWA's application checklist calls for 40°F and rising, a dry surface and dry cracks, and no rain on the way; SealMaster says the air and the pavement must both be above 40°F. The sealant goes down at 350-400°F. Cold-pour filler needs warmer weather: SealMaster says not to use it if the temperature will drop below 50°F within 24 hours.
FHWA's manual puts rubberized sealant, banded over routed working cracks, at 5-9 years, and banded over cracks that were not routed at 2.5-5 years. NCAT's test sections showed why it is worth doing: unsealed pavement developed 12-33% more cracking, and sealed sections less than half of that.
Hot-pour rubberized sealant is the commercial standard, and it is what the bands and service lives on this page are for. Cold-pour comes in jugs, needs no melter and suits a handful of narrow cracks: SealMaster says a gallon fills about 75-150 ft of cracks up to 1/2 inch. On a lot with hundreds of feet, the melter pays for itself in time.
