Driveway Sealing Cost by Size

Size is the main driver of cost on a driveway sealing job. Most contractors in your area will price by the square metre, so knowing your approximate driveway area gives you a reliable starting estimate before requesting quotes.

Estimated driveway sealing costs by size:

Driveway Size	Estimated Cost
Small (terraced or semi)	£120-£220
Medium (standard detached)	£200-£400
Large (double width or long)	£350-£600
Very large	£500-£800+

These figures are for a standard single-coat sealant application on a clean, sound surface in reasonable condition. If the driveway needs cleaning first, or if block paving joints require re-sanding before sealing, those are typically priced separately, more on that below.

Driveway Sealing Cost by Surface Type

The surface material affects both which sealant is appropriate and how much preparation is needed before it can be applied. Block paving, tarmac, concrete, and resin all have different requirements, and different price points.

Typical driveway sealing costs by surface type (40m²):

Surface Type	Sealing Cost (per m²)
Tarmac / asphalt	£3-£6
Block paving (seal only)	£4-£8
Block paving (re-sand and seal)	£6-£10
Pattern-imprinted concrete	£2-£3.50
Resin-bound	£5-£9

• Block paving is the most involved surface to seal correctly. The joints between blocks need to be re-sanded with kiln-dried sand before the sealant is applied, if the joints are loose or depleted, sealing without re-sanding locks in the problem rather than fixing it. Always confirm whether re-sanding is included in a block paving sealing quote, as it's frequently priced as an add-on.

• Tarmac is the most straightforward and affordable surface to seal. A quality tarmac sealant applied every three to five years slows down surface oxidation, reduces water penetration, and helps prevent the cracking that freeze-thaw cycles cause over time. See our tarmac driveway cost guide if your surface is showing signs of more serious wear.

• Pattern-imprinted concrete is often the cheapest surface to seal per m², the smooth, non-porous surface requires minimal preparation and takes sealant quickly. A two-coat application is sometimes recommended to achieve full coverage.

• Resin-bound driveways require a compatible sealant and a gentle hand, incompatible products or aggressive application can cloud the surface or lift the aggregate. A contractor familiar with resin surfaces is worth specifying when booking.

Types of Driveway Sealant and Their Costs

Choosing the right sealant makes a real difference to both how long your driveway stays protected and what you pay over time. There's a good option at every budget - from affordable acrylic sealants that do a solid job on most standard driveways, to longer-lasting polyurethane and resin-based products that reduce how often you need to reseal.

Acrylic Sealers: £3-£5 per m²

Acrylic sealers sit on the surface rather than penetrating it, providing a protective film that refreshes colour and repels light water and staining.

They're the most affordable option and widely used on block paving and tarmac, but they wear off faster than penetrating products, typically needing reapplication every one to three years in the UK climate.

Polyurethane Sealers: £6-£10 per m²

Polyurethane sealers are tougher, more flexible, and more resistant to oil, UV, and heavy traffic than acrylic. They're better suited to driveways that see regular vehicle use and are worth the additional cost on any surface you want protected for the longer term.

Resin-Based and Penetrating Sealers: £7-£12 per m²

Resin-based and penetrating sealers bond into the surface rather than sitting on top of it, offering the most durable protection and the longest interval between applications.

They're particularly effective on block paving and natural stone, where surface penetration locks in the pointing sand and reduces water ingress at joint level. The higher upfront cost generally works out more economical over a five-year period than repeated acrylic treatments.

Note: On any surface more than 12 months old that has been sealed before, it's worth checking compatibility between the existing sealant and the new product before applying. Some sealants don't bond well over others, a professional will check this before starting.

Signs Your Driveway Needs Resealing

Most driveways benefit from resealing every two to five years depending on material, traffic, and weather exposure. The signs below indicate the existing seal has broken down and the surface is no longer protected.

• Water no longer beads on the surface: A properly sealed driveway sheds water in droplets. When water soaks straight in rather than running off, the sealant has worn through and the surface is exposed to moisture damage.

• Fading or patchy colour: Sealant protects against UV damage and surface oxidation. A driveway that looks noticeably duller or more uneven in colour than it did a few years ago has typically lost its protective layer.

• Moss and algae returning quickly after cleaning: A sealed surface is much harder for organic growth to take hold on. If moss is returning within a few months of cleaning, the sealant is no longer doing its job.

• Oil stains that won't lift: Sealant prevents oil from penetrating the surface. If staining is soaking into the driveway rather than sitting on top of it, the surface is unsealed or the seal has broken down.

• Fine surface cracking: Particularly common on tarmac and concrete driveways where freeze-thaw cycling has started to open hairline cracks. Sealing at this stage prevents water from getting into the cracks and widening them - left too long, the damage progresses from cracking to a repair job. See our driveway repair cost guide if the surface has moved beyond the point where sealing alone will help.

It's generally not worth sealing a brand-new driveway for the first 6-12 months. New surfaces need time to cure and settle, and applying sealant too early can trap moisture or prevent the surface from hardening properly.

What Affects the Cost of Driveway Sealing?

Getting a quote for driveway sealing is straightforward, but what's included in that quote can vary considerably between contractors. Understanding what moves the price helps you compare quotes accurately.

Surface preparation: A driveway that needs pressure washing before sealing will cost more than one that was cleaned recently. Most contractors either include cleaning in their quote or price it separately.

For block paving, re-sanding depleted joints is an additional step that's often not included in a base sealing price, always confirmed upfront.

Number of coats: Some surfaces and sealant types require two coats for adequate coverage, which adds labour time and material cost. Pattern-imprinted concrete in particular often benefits from a second coat. A quote should specify how many coats are included.

Crack repairs: Minor surface cracks should be filled before sealing, applying sealant over open cracks locks moisture into the crack rather than protecting against it. Small crack repairs add £50–£150 depending on the number and severity, and are sometimes included in a combined quote.

Location: London and the South East typically run 10-20% higher than the national average for driveway work. The North of England, Scotland, and Wales generally come in at the lower end of price ranges.

Driveway condition: An older or more worn surface may require additional preparation, cleaning, weed treatment, crack filling, before sealing can be applied effectively. A site visit is the most reliable way to get an accurate quote for a surface that's been neglected.

MyBuilder Tip: When comparing quotes, ask each contractor to confirm what's included: preparation, cleaning, number of coats, re-sanding (for block paving), and drying time before the driveway can be used. Two quotes at similar totals can represent very different scopes of work.

FAQ: Common Questions About Driveway Sealing Costs

How Much Does It Cost to Seal a Driveway in the UK?

For a standard 40m² driveway, professional sealing typically costs £200–£400 for a single coat of sealant including labour, or roughly £5-£8 per m². Tarmac driveways are at the lower end; block paving that also needs re-sanding runs higher. Larger driveways cost more in total but often benefit from a slightly lower per-m² rate. You can browse completed driveway sealing projects on MyBuilder to see examples of the work and finish quality before requesting quotes.

How Often Should I Seal My Driveway?

It depends on the surface and the sealant used. Acrylic sealants typically last one to three years; polyurethane and resin-based products last three to seven years in normal UK conditions. For most block paving and tarmac driveways, resealing every two to three years is a practical maintenance schedule. The clearest signal that resealing is due is when water stops beading on the surface and soaks in instead.

Is It Worth Sealing a Driveway?

For most surfaces, yes. Particularly block paving and tarmac. Sealing prevents water ingress, slows moss and algae growth, reduces oil staining, and extends the interval between professional cleans. The cost of periodic sealing is generally lower than the cost of accelerated wear, repeated cleaning, or early resurfacing. On a brand-new driveway, wait 6–12 months before applying sealant to allow the surface to cure fully.

Should I Clean My Driveway Before Sealing It?

Yes. Sealing over a dirty surface locks in the dirt and prevents the sealant from bonding properly. Pressure washing immediately before sealing is the standard approach, and many driveway specialists offer combined cleaning and sealing as a single visit. For block paving, re-sanding the joints after cleaning and before sealing is also recommended to stabilise the surface and close the joints before the sealant is applied. See our driveway cleaning cost guide for a full breakdown of what professional cleaning costs.

Can I Seal My Driveway Myself?

DIY sealing is possible using off-the-shelf sealant products, particularly for tarmac and concrete surfaces. Basic acrylic sealants are available in 5-25 litre tubs and can be applied by roller. The risks with DIY are uneven coverage, applying the wrong product for the surface type, and sealing over a surface that hasn't been adequately cleaned - all of which can produce a patchy result that looks worse than the unsealed surface.

For block paving, professional re-sanding before sealing requires specific materials and techniques that most homeowners aren't set up to do well. For larger or more visible driveways, the cost of professional application is generally worth it for a consistent finish.
