Caulking is one of the least expensive things we do, and one of the hardest to price over the phone. "How much to caulk my driveway?" depends on a number almost nobody has measured: how many feet of joint you actually have.
You can measure it in about ten minutes with a tape measure. Once you have that number, the math is simple, and you can hold it up against doing the job yourself.
Open cracks price the same way. On a slab that's still level, concrete crack repair cost comes down to the same per-foot math as the joints. What the work itself includes is on our joint and crack sealing page.
Our Caulking Prices, Job by Job
We price caulking by the linear foot: $5–$10 per foot for control joints, expansion joints, open cracks, and the gap where concrete meets the house. Where a job lands in that range depends on joint width and depth, how much old material has to come out, and backer rod. Booked on its own, caulking has a $275 minimum. That covers the drive, setup, and cleanup, and a small job of about 4 to 6 sidewalk joints or up to about 30 feet. Added to a lifting job, it has no separate minimum: you pay the footage. Booked together with a sealing job or a clean-and-seal, it's all one job, and bundling can lower the overall price.
| Job | Typical joint footage | Booked alone | Added to a lift |
|---|---|---|---|
| Front stoop and the gap at the house | 10–20 ft | $275 minimum | $50–$200 |
| Front walk, 4 ft wide | 25–35 ft | $275–$350 | $125–$350 |
| Patio along the house, about 12 × 16 | 30–45 ft | $275–$450 | $150–$450 |
| Short two-car driveway, 20 × 24 | 60–100 ft | $300–$1,000 | $300–$1,000 |
| Longer two-car driveway, 20 × 40 | 120–140 ft | $600–$1,400 | $600–$1,400 |
| Driveway, walk, stoop, and patio together | 150–220 ft | $750–$2,200 | $750–$2,200 |
Booked alone, the stoop always comes in at the minimum, and the walk and patio often do, so if the stoop and the patio both need it, do them on the same trip. At the other end, a driveway with 10 or more joints or 100-plus feet of them can reach $1,000 or more. And the footage column is a typical layout, not yours, which is why the next step is worth ten minutes.
For context, national cost guides updated in 2026 put general professional caulking at about $1.25–$4 per linear foot. Our $5–$10 sits above that, and we'd rather you hear it from us. Those national figures mostly describe windows, trim, and tubs. A concrete joint is a different job: it swallows a lot more sealant per foot, as the material table below shows, and it often needs old caulk or wood dug out and backer rod set before any sealant goes in. For how caulking is priced next to lifting and garage floor coatings, see our pricing overview.
Measure Your Footage in Ten Minutes
Grab a 25-foot tape, a flat screwdriver, and the notes app on your phone.
- 1List every jointWalk each slab and note the straight grooves (control joints), the full-depth gaps with strips or old caulk in them (expansion joints), the joint where the driveway meets the garage floor, the joint at the street apron or public walk, and every spot where concrete meets the house, the steps, or another slab.
- 2Measure each run end to endA joint across the driveway is as long as the driveway is wide. A joint running down the middle is as long as the driveway.
- 3Add open cracksCount any crack a credit card slides into. Skip hairlines.
- 4Check the width of a few jointsMost are 1/4" to 1/2". Old wood strips can be 1" to 1-1/2". Note which joints are which.
- 5Total it
Here's a typical northeast Wisconsin layout: a two-car driveway 20 feet wide and 24 feet long, a 4-foot front walk 30 feet long that's scored every 5 feet, and a 6-foot stoop against the house.
| Where | How to figure it | Feet |
|---|---|---|
| Driveway, joint down the middle | Driveway length | 24 |
| Driveway, crosswise joint halfway down | Driveway width | 20 |
| Driveway meets the garage floor | Driveway width | 20 |
| Driveway meets the apron or public walk | Driveway width | 20 |
| Walk, crosswise joints every 5 feet | 5 joints × 4 ft | 20 |
| Walk meets the driveway and the stoop | 2 × 4 ft | 8 |
| Stoop meets the house | Stoop width | 6 |
| Total | 118 ft |
At $5–$10 per foot, 118 feet comes to $590–$1,180. That's the same added to a lift or booked alone, since it's well past the $275 minimum.
A longer driveway changes it fast. At 20 × 40, with joints roughly every 10 to 12 feet, the driveway by itself picks up another crosswise joint or two and a longer center joint, which puts it around 120 to 140 feet before you count the walk. A driveway with no center joint can drop to about 60.
Count wood strips separately. You'll see why next.
Why Some Feet Cost More Than Others
Two driveways with the same footage can price at opposite ends of the range. These are the things that move it.
Wide joints swallow sealant
A sealant bead should be about half as deep as the joint is wide, and generally between 1/4" and 1/2" deep. So a wider joint takes a fatter bead, and the sealant per foot climbs quickly.
Here's what the sealant alone costs per foot at current home-center prices, using two 10.1-ounce polyurethane self-leveling tubes listed at $9.40 and $10.97 in October 2026. This is before waste and before backer rod. A 10.1-ounce tube holds about 18 cubic inches.
| Joint width | Bead depth | Feet per tube | Sealant cost per foot |
|---|---|---|---|
| 1/4" | 1/4" | About 24 | About $0.39–$0.45 |
| 1/2" | 1/4" | About 12 | About $0.77–$0.90 |
| 3/4" | 3/8" | About 5 | About $1.75–$2.05 |
| 1" | 1/2" | About 3 | About $3.10–$3.60 |
| 1-1/2" (old wood strip) | 1/2" | About 2 | About $4.65–$5.40 |
That table explains most of the spread in caulking prices. A narrow control joint is mostly labor. A 1-1/2" gap left by a rotted two-by is mostly sealant, even at retail. That's why ordinary 1/2" joints sit toward the low end of our range, and a driveway full of wide wood-strip joints sits toward the top of it. If yours has those, your quote will say so.
Backer rod is cheap, and it saves money
Closed-cell backer rod runs about $4–$8 a roll at home centers. Most rolls are 20 feet, and some larger sizes come in 10-foot lengths. It sets the bead depth and keeps the sealant gripping only the two sides of the joint, so it can stretch in January instead of tearing.
It also keeps you from filling a deep joint with sealant that does nothing. Fill a 1" joint 2 inches deep with no rod and you've used four times the sealant of a proper 1/2"-deep bead, and built a plug that can't flex. Sizing details are in our concrete crack caulk guide.
Whatever has to come out first
Sealant needs clean, bare concrete to bond. Old caulk has to be cut out completely, rotted wood and crumbling fiberboard have to be pulled, and the sand, weeds, and roots have to go before anything goes in.
Clean, empty control joints go fast. A grid of 40-year-old wood strips is a different day. This is the single biggest labor swing in caulking, and it's why the quote asks for close-ups. If you're curious what's under your strips, our guide to filling expansion joints shows how to check.
On a lifting job, any joint that would bind gets cleaned out anyway so the slab can rise freely, which is part of why caulking added to a lift carries no minimum of its own.
The gap at the house
The joint where a stoop, patio, or walk meets your foundation is usually short but fussy. It's often wider at one end than the other, sometimes turns up a vertical face, and sits next to siding, door thresholds, and brick weep holes that have to stay clean and open. Expect it to price per foot toward the upper half of the range.
One firm rule: if that slab tips toward the house, it gets lifted before it gets sealed. Caulking a backward-sloped slab just seals water against your foundation. More in caulking where concrete meets the house.
Lots of short pieces
Stoop steps, joints that dead-end at posts, and cracks that wander across a slab all mean more setup per foot than one long, straight driveway joint.
Doing It Yourself: The Real Shopping List
Caulking is one of the most DIY-friendly concrete jobs there is, and the material math is on your side. For the 118-foot example above, mostly 1/2" joints:
| Item | How much | Cost |
|---|---|---|
| Polyurethane self-leveling sealant | About 10 tubes, plus 10–15% because real joints wander: 11–12 tubes | About $100–$135 |
| Closed-cell backer rod | 118 ft plus extra: 6–7 rolls of 5/8" | About $30–$35 |
| Caulk gun, utility knife, wire brush | One of each | About $10–$30, the range cost guides list for application tools |
| Shop vac or leaf blower | For the dust | Probably already in your garage |
| Total | About $140–$200 |
Next to that, our price on the same footage is $590–$1,180, with a lift or booked alone.
What the shopping list leaves out:
- Your time. An afternoon if the joints are clean and open. A weekend or more if there's old caulk or wood to dig out, on your knees.
- The weather window. Most joint sealants want at least 40°F and a dry, frost-free joint. Green Bay's normal overnight low is about 39.5°F in October and about 35°F in April, so the comfortable window is late spring through September.
- The do-over risk. A bead laid in a damp joint, or without backer rod, can pull loose after one winter. Then it all gets cut out and redone, and you've bought it twice.
DIY makes the most sense when the slabs are level, the joints are narrow, there's little to dig out, and you have a dry September weekend. You don't need us for that.
The math flips when a slab has dropped at a joint (that's a lift first, and lifting isn't DIY), when there are dozens of wood strips to pull, or when the slab at the house tips the wrong way.
What Skipping It Costs
An open joint is a funnel to the soil under two slabs at once. Around here that soil is often red, clay-rich glacial till, which holds water and is among the most frost-prone soils there is. Water that gets in during fall freezes and expands about 9 percent. Spring snowmelt runs in all at once. Downspouts and sump lines send whole streams down the nearest joint.
Here's how the cost of that climbs, in relative terms:
| Stage | What's happening | Usual fix | Relative cost |
|---|---|---|---|
| Open joint | Water, sand, and weeds getting in | Caulk | The least: dollars per foot |
| Edge washout | A hollow starting under the slab edge | Caulk, sometimes foam to fill the void | Low to moderate |
| Slab dropped | A trip edge, water running toward the house or garage | Lift, then caulk | A lift on top of the caulking |
| Slab broken up | Pieces that rock, a slab that's past saving | Replace the section | The most: new concrete costs more than a lift |
To put real numbers on it: caulking a short two-car driveway runs about $300–$1,000 with us, which is in the same range as lifting one section of it ($550–$800). So caulking the whole driveway isn't automatically cheaper than one lift. The case for it is what comes later. Let water run in until two or three sections drop, and lifting them runs $1,100–$2,400, with the joints still needing sealant afterward. And if a sinking section cracks into pieces, recent local data puts Green Bay-area tear-out and replacement at roughly $8–$15 per square foot, or about $800–$1,500 for a single 10 × 10 section.
Caulking doesn't guarantee a slab never moves. A downspout dumping beside the driveway can still soften the soil at its edge. But it shuts off the easiest way in. For the full case, see why caulk concrete joints.
When Caulking Is Money Wasted
We'd rather tell you this than sell you footage you don't need:
- Hairline cracks with both sides flush. Sealant smeared over them tends to peel off. Mark them and check again next spring.
- Joints with sealant that's still working. If the last bead is soft, stuck to both sides, and not split, leave it.
- Joints where one side dropped. A bead on an offset leaves the trip edge and the hollow underneath. Lift first.
- Crumbling joint edges. Sealant needs solid concrete to grip. That's an edge repair for a concrete contractor, not a service we offer.
- A driveway you're replacing next year. Put the money toward the new one.
- Inside a garage you plan to coat. Coatings don't bond to flexible caulk. Cracks there get a rigid filler during coating prep.
