Is it cheaper to seal a driveway yourself or hire a contractor?

DIY sealing costs $60–$200 in materials for an average residential driveway vs $200–$500+ for professional service. The DIY material cost is 3–5x cheaper, but professional application includes crack prep, edging, and often a higher-solids commercial product. For a well-maintained driveway with no cracks, DIY makes sense. For driveways with cracks or surface damage, professional prep-and-seal is usually better value long-term.

Asphalt Sealer Prices — Cost Per Gallon, Bucket & Brand (2026)

Q: How much does asphalt sealer cost per gallon?

Asphalt sealer costs $1.50–$4 per gallon depending on type. Coal tar emulsion runs $1.50–$2.50/gallon, asphalt emulsion $2–$3.50/gallon, acrylic sealer $3–$5/gallon, and oil-based sealer $4–$8/gallon. These are raw per-gallon prices — most products are sold in 4.75 or 5-gallon buckets retailing for $15–$60.

Q: How much does a 5-gallon bucket of driveway sealer cost?

A standard 5-gallon bucket of driveway sealer costs $18–$60 at home improvement stores in 2026. Budget coal tar emulsion (Quikrete, Latex-ite) runs $18–$28. Mid-range asphalt emulsion buckets are $28–$42. Premium acrylic and polymer-modified sealers run $42–$65. Always check the coverage rate on the label — cheaper buckets often cover 200–250 sq ft vs 300–400 sq ft for premium products.

Q: How much sealer do I need for my driveway?

Most driveway sealers cover 250–400 sq ft per 4.75-gallon bucket when applied at the recommended rate. A 400 sq ft driveway (20x20 ft) needs 1–2 buckets. A 1,000 sq ft driveway needs 2–4 buckets. A 2,000 sq ft driveway needs 5–8 buckets. Porous, weathered, or dry asphalt absorbs more and may require a second coat, which roughly doubles material cost.

Q: Where is the cheapest place to buy asphalt sealer?

Home Depot and Lowe's typically offer the best retail prices on standard driveway sealers, often running seasonal sales in spring and fall with 10–20% off. Contractor supply houses like SealMaster sell commercial-grade sealer at lower per-gallon rates but require higher minimum purchases (55-gallon drums). Buying in bulk (multiple buckets at once) from warehouse clubs or online can save 10–15% vs single-bucket retail pricing.

Worker applying black asphalt sealer to driveway with squeegee

Walk into any Home Depot and you'll see six different asphalt sealers on the shelf — prices ranging from $18 to $65 per bucket. They look almost identical. The cheap one promises 250 sq ft of coverage; the expensive one claims 400 sq ft. Which one actually wins on cost-per-square-foot? And how does any of it compare to hiring a contractor?

This guide breaks down every asphalt sealer price — by type, container size, and brand — so you know exactly what you're paying for before you buy.

Quick Answer: How Much Does Asphalt Sealer Cost?

A 4.75–5 gallon bucket of driveway sealer costs $18–$65 at retail in 2026. Budget coal tar emulsion runs $18–$28. Mid-range asphalt emulsion is $28–$45. Premium acrylic or polymer-modified sealer is $45–$65. Coverage ranges from 200–400 sq ft per bucket — always calculate cost-per-sq-ft, not just sticker price.

Sealer Type Price Comparison

The biggest factor in sealer price is the base chemistry. Here's what each type costs and what you get for the money:

Sealer Type	Price / 5 gal	Price / Gallon	Coverage / Bucket	Cost / Sq Ft	Lifespan
Coal tar emulsion	$18–$28	$3.60–$5.60	200–300 sq ft	$0.06–$0.14	2–4 years
Asphalt emulsion	$28–$42	$5.60–$8.40	250–350 sq ft	$0.08–$0.17	2–4 years
Acrylic sealer	$42–$58	$8.40–$11.60	300–400 sq ft	$0.10–$0.19	3–5 years
Oil-based / penetrating	$38–$65	$7.60–$13	200–300 sq ft	$0.13–$0.32	3–6 years
Polymer-modified emulsion	$45–$70	$9–$14	300–450 sq ft	$0.10–$0.23	4–7 years

          Don't shop on bucket price alone. A $22 coal tar bucket covering 200 sq ft costs $0.11/sq ft. A $48 polymer-modified bucket covering 400 sq ft costs $0.12/sq ft — almost the same per-square-foot, but the polymer product lasts 2–3 years longer.
        

Price by Container Size

Sealers come in several sizes. Bigger containers offer better value per gallon but require storage and commitment to applying it all in one season.

Container Size	Typical Price Range	Best For
1 gallon	$8–$18	Touch-ups, small areas, testing a product
4.75–5 gallon bucket	$18–$65	Standard residential driveways (400–1,200 sq ft)
7 gallon pail	$30–$80	Mid-size driveways or second coat coverage
30 gallon drum	$120–$220	Large driveways, multi-unit properties
55 gallon drum	$200–$380	Contractor purchase, commercial lots

For most homeowners, 5-gallon buckets are the sweet spot. They're easy to handle, widely available, and priced for single-driveway jobs without the waste of a drum.

Brand-by-Brand Price Comparison

Here's what the major brands actually cost at Home Depot, Lowe's, and online as of 2026:

Brand	Product	5 gal Price	Type	Coverage	Where to Buy
Quikrete	Blacktop Sealer	$18–$22	Coal tar emulsion	200–250 sq ft	Home Depot, Lowe's
Latex-ite	Airport Grade	$20–$26	Coal tar emulsion	250–300 sq ft	Home Depot
Latex-ite	Pli-Stix + Sealer	$28–$35	Asphalt emulsion	275–325 sq ft	Home Depot
Gardner	10-Year Driveway Sealer	$32–$40	Asphalt emulsion	300–350 sq ft	Home Depot, Lowe's
Rust-Oleum	RockSolid Driveway Resurfacer	$44–$58	Acrylic	350–400 sq ft	Home Depot, online
SealMaster	HS-200 Emulsion	$38–$52	Polymer-modified	350–450 sq ft	Contractor supply
Neyra	Jet Black Premium	$45–$60	Polymer-modified	400–500 sq ft	Contractor supply
GemSeal	Pavement Sealer	$40–$55	Polymer-modified	375–450 sq ft	Contractor supply

Pro tip: SealMaster, Neyra, and GemSeal are contractor-supply brands not typically stocked at big-box stores. If you can buy them, you're getting commercial-grade solid content (28–35%) vs the 18–22% typical of retail brands — meaning better protection per coat.

Solid Content: The Spec That Actually Matters

Solid content is the percentage of active sealer material left after the water carrier evaporates. Higher solid content = thicker film = better protection and longer lifespan. Most budget retail sealers run 18–22% solids. Premium products hit 28–35%.

Solid Content	Product Tier	Typical Price / 5 gal	Expected Lifespan
15–20%	Budget retail	$18–$26	1–2 years
20–25%	Mid-range retail	$28–$42	2–3 years
25–30%	Premium retail / entry contractor	$42–$58	3–5 years
30–35%+	Contractor-grade	$45–$70	4–7 years

Coverage Rate & Cost Per Square Foot

Coverage varies by product, application method, and surface condition. Porous or rough asphalt soaks up more sealer and reduces effective coverage. Here's a realistic breakdown:

Surface Condition	Coverage per 5-gal Bucket	Effect on Cost
New / smooth asphalt	350–450 sq ft	Maximum coverage
2–5 year old asphalt	300–375 sq ft	+10–15% material cost
5–10 year old asphalt	250–325 sq ft	+20–30% material cost
Very weathered / porous	175–250 sq ft	+40–60% material cost

Always plan for at least 10% extra material. Weathered driveways may need two coats — the first fills the pores, the second provides the actual protective film.

Total DIY Material Cost by Driveway Size

Using mid-range asphalt emulsion sealer (~300 sq ft coverage per 5-gal bucket, $32/bucket) as the baseline:

Driveway Size	Square Footage	Buckets Needed	Material Cost	With 2nd Coat
1-car (10×20 ft)	200 sq ft	1	$32	$64
Standard (20×20 ft)	400 sq ft	1–2	$32–$64	$64–$128
Large 2-car (24×30 ft)	720 sq ft	2–3	$64–$96	$128–$192
Extended (30×40 ft)	1,200 sq ft	3–4	$96–$128	$192–$256
Extra large (50×40 ft)	2,000 sq ft	5–7	$160–$224	$320–$448

DIY Sealing vs Hiring a Contractor

Buying sealer is only one part of the cost equation. Here's how DIY compares to professional service on a typical 600 sq ft driveway:

Cost Item	DIY	Professional
Sealer material (2 coats)	$80–$140	Included
Crack filler	$15–$40	Included
Squeegee / applicator	$20–$35 (reusable)	Included
Edging tape / supplies	$10–$20	Included
Labor	3–5 hours your time	Included
Total	$125–$235	$250–$500

DIY saves roughly $150–$300 on a typical driveway. The trade-off: contractors use commercial-grade sealer, apply it more evenly, and often provide a warranty on the work. For a well-maintained driveway in good condition, DIY is hard to beat on cost. For a driveway needing crack repair or prep work first, professional service often delivers better long-term value.

For a full breakdown of professional sealing costs, see Sealcoating Cost: DIY vs Professional (2026).

Tip: Whatever product you choose, read the coverage rate on the label and calculate cost-per-sq-ft before buying. A $45 premium bucket covering 400 sq ft often beats a $22 budget bucket covering 200 sq ft — same cost, better product.

Frequently Asked Questions

How much does asphalt sealer cost per gallon?

Asphalt sealer costs $1.50–$13 per gallon depending on type. Budget coal tar emulsion runs $3.60–$5.60/gallon. Mid-range asphalt emulsion is $5.60–$8.40/gallon. Premium acrylic and polymer-modified sealers run $9–$14/gallon. These prices are derived from typical 5-gallon bucket retail pricing.

How much does a 5-gallon bucket of driveway sealer cost?

A 5-gallon bucket costs $18–$65 at retail in 2026. Budget options (Quikrete, Latex-ite) run $18–$28. Mid-range products are $28–$45. Premium acrylic and polymer-modified sealers are $45–$65. Always compare coverage rates — cheaper buckets often cover 200–250 sq ft vs 350–450 sq ft for premium products.

How much sealer do I need for my driveway?

Most sealers cover 250–400 sq ft per 4.75–5 gallon bucket. A 400 sq ft driveway needs 1–2 buckets. A 1,000 sq ft driveway needs 2–4 buckets. A 2,000 sq ft driveway needs 5–8 buckets. Add 10% buffer for edges and porous spots, and plan for two coats on weathered surfaces.

What is the cheapest driveway sealer that actually works?

Latex-ite Airport Grade and Quikrete Blacktop Sealer are the most affordable options that still hold up well, at $18–$26 per bucket. Both provide solid 2–3 year protection on residential driveways. Avoid no-name sealers under $15 — thin consistency and low solid content mean they fade within one season.

Where is the cheapest place to buy asphalt sealer?

Home Depot and Lowe's offer the best retail prices, especially during spring and fall sales (10–20% off). Contractor supply houses like SealMaster offer lower per-gallon rates on commercial-grade products but require bulk purchases.
