What changes the cost of sealing a driveway?
A driveway sealing quote depends on the surface, its size, how much cleaning and repair it needs first, whether block paving joints need re-sanding, and the sealer used. The preparation is often most of the work, so this guide prints no price and explains what each quote should cover.
Last reviewed:What does sealing a driveway mean?
Sealing means applying a liquid coating to a driveway surface. Once it cures, it protects the surface and changes how it looks and behaves. People seal driveways to:
- hold the sand in block paving joints, so it doesn't wash or sweep out
- slow the return of weeds and moss in the joints
- make oil and other spills easier to clean off
- refresh faded colour, or add a sheen
- protect concrete or tarmac from water and frost getting into the surface
Sealing is a protective job for a surface that is still in good shape. If the drive is cracked, sunken or breaking up, sealing won't fix it. Driveway repair covers fixing failed areas first, and driveway resurfacing covers a new top layer.
This guide does not print a price per square metre. It explains what goes into a sealing job and what a quote should list, so you can compare contractors on the same terms.
QuoteZila starts in Cheshire, with Crewe, Nantwich and Sandbach first, and anyone in the UK can post a driveway job.
Why is preparation most of the job?
A sealer locks in whatever is on the surface when it goes on. That is why careful contractors spend more time preparing than sealing.
Cleaning. Usually a pressure wash to lift dirt, moss and algae. On block paving this also blows out much of the old joint sand. Driveway cleaning explains that part of the job.
Weed and moss treatment. Roots left in joints will push back through.
Stain treatment. Oil, rust and tyre marks may need a specific cleaner before sealing. Some stains won't fully lift.
Drying. The surface usually needs to be dry before sealing. After a wash, that can mean waiting a day or more depending on the weather.
Re-sanding block paving. Once joints are cleaned out, they are refilled with dry sand and brushed in. Some sealers are designed to help bind that sand.
Small repairs. Rocking blocks, cracked slabs or potholes should be dealt with before sealing, not sealed over.
A quote that says only "seal driveway" leaves out most of what you are paying for. Ask each contractor to list every stage.
What changes the price of sealing?
| Factor | What to ask | Why it changes the cost |
|---|---|---|
| Surface | Block paving, tarmac, concrete, resin or natural stone? | Each needs a sealer made for it |
| Size and shape | How many square metres, and how many edges and steps? | More area and more cutting-in take longer |
| Condition | How much moss, staining and loose sand? | Heavy cleaning and stain removal add time |
| Joint work | Will block joints be re-sanded, with what sand? | A full re-sand is a separate stage |
| Repairs first | Any blocks to relay or cracks to fix? | Should be priced and done before sealing |
| Sealer type | Product name, finish (matt, satin, wet look), number of coats | Products and coats differ in cost and life |
| Weather | What happens if it rains on the day? | Delays and return visits |
| Access | Is the drive shared, or do cars need moving for days? | Splitting the job adds visits |
| Waste water | Where does wash water and debris go? | Clearing up is part of the job |
| VAT | Included or added? | Registration is required above £90,000 of taxable turnover in the last 12 months [S2] |
Which sealer suits which surface?
Sealers are made for particular surfaces, and using the wrong one can leave a patchy, peeling or slippery finish. In broad terms:
- Concrete block paving often takes a sealer designed for blocks, sometimes with a joint-stabilising effect.
- Clay pavers are a different material from concrete blocks, and not every block sealer suits them.
- Tarmac has its own sealers and restorers, often black, which can refresh faded tarmac.
- Plain and imprinted concrete take concrete sealers, and imprinted concrete is often resealed to keep its colour.
- Resin-bound surfaces may need a product approved by the system maker, if any.
- Natural stone varies widely and may need a stone-specific product, or none.
Ask each contractor which product they will use and why it suits your surface. If you have the maker's details for your blocks or resin, share them, because some makers give their own advice about sealing.
Slip. A glossy "wet look" finish can be more slippery when wet, especially on slopes and steps. Ask whether an anti-slip additive is available.
Does sealing affect drainage or planning?
It can affect how water drains, which links back to the planning rules for front gardens.
The Planning Portal says a new or replacement driveway of any size doesn't need planning permission if it uses a permeable or porous surface that lets water drain through, such as gravel, permeable concrete block paving or porous asphalt, or if rainwater runs to a lawn or border [S3]. It says more than five square metres of traditional impermeable driveway that doesn't let water run to a permeable area needs planning permission [S3]. GOV.UK guidance explains ways of building a driveway that reduces rainwater running into drains, using permeable surfaces, soakaways and rain gardens [S4].
Sealing an existing drive is a maintenance job, not a new driveway. But if your drive was built as a permeable surface, ask the contractor whether their sealer will close up the joints or pores, and whether a different product, or no sealer, would be better.
What can go wrong with a sealed driveway?
Most problems with sealing come from the preparation or the weather rather than the product.
Cloudy or white patches. Often caused by sealing a surface that was still damp, or by rain falling before the sealer cured.
Peeling or flaking. Can happen when a sealer goes over dirt, old sealer that wasn't compatible, or a surface it wasn't made for.
Uneven colour. Wheel tracks wear faster than the rest, and patches of new blocks may take the sealer differently from old ones.
Slippery finish. Glossy coatings on slopes and steps can be slippery when wet.
Weeds coming back. If roots were left in the joints, or joints were only half filled with sand, weeds can return through the sealer.
Ask each contractor what they would do if any of these happened after their work, and whether they would come back to put it right.
Can you seal a driveway yourself?
Many people do, and sealers are sold for home use. If you do it yourself, follow the maker's instructions on the tin for surface type, weather, drying time and number of coats, and test a small area first. The risks are mostly to the finish: a patchy or slippery result can be hard to undo, and stripping a failed sealer is a bigger job than sealing.
A contractor brings pressure-washing kit, joint sand and experience of which products suit which surfaces. Comparing a professional quote with the cost of hiring a pressure washer and buying the sealer and sand yourself can help you decide.
How do you compare driveway sealing quotes?
Ask each contractor for the same things in writing:
- the size of the area and what is included
- each stage: cleaning, weed treatment, stain removal, re-sanding, repairs, sealing
- the product and finish, and how many coats
- how long to keep off the drive, for people and for cars
- what happens if rain arrives during or soon after the job
- how long the sealer is expected to last, and what resealing involves
Citizens Advice says a quote is a fixed price, while an estimate is just a rough guess, so you might end up paying more [S1]. It suggests getting written quotes from at least 3 different traders, and says some traders charge for quotes, so ask about this first [S1].
If the finish peels, patches or clouds soon after, Citizens Advice says the Consumer Rights Act 2015 requires services to be provided with reasonable care and skill [S5].
Our driveways and paving page covers the trade, and some cleaners who offer pressure washing also seal. For the cost of a whole new drive, see our driveway cost guide.

Questions about sealing a driveway
How much does it cost to seal a driveway?
This guide does not print a figure. A small, clean, recently laid drive is quick to seal. An older drive that needs deep cleaning, weed removal, re-sanding and a two-coat sealer takes much longer. Ask each contractor to price the cleaning, joint work and sealing as separate lines.
Does block paving need sealing?
It isn't essential. Sealing can help keep joint sand in place, reduce weeds and make cleaning easier, and some sealers change the colour or sheen. Some block makers have their own advice on whether to seal, so check what was used on your drive.
How soon can I drive on a sealed driveway?
It depends on the sealer, the weather and how many coats go on. Ask the contractor how long to keep people and vehicles off, and plan for it, because rain soon after sealing can spoil the finish.
Will sealing stop my driveway being permeable?
Ask before work starts. If your drive was laid as a permeable surface so that rain drains through, a sealer that closes the joints or pores could change how it works. Choose a product that suits a permeable surface, or don't seal it.
How often does a driveway need resealing?
It varies with the sealer, the surface and the traffic. Wheel tracks usually wear first. Ask each contractor how long their sealer is expected to last on your drive and what resealing involves.
Is the cleaning included in a sealing quote?
It should be, because sealing over dirt, moss or oil seals the stain in. Check the quote names the cleaning method, any weed or moss treatment, and how long the surface will be left to dry before sealing.
Does QuoteZila check driveway contractors?
No. We don't check insurance, qualifications or registrations, so please check these yourself before you hire. You can report a quote or a business from your job page.
This page is general information, not professional or legal advice. QuoteZila does not check Gas Safe, WaterSafe, NFRC, NICEIC or other registrations against the register on your behalf: look them up yourself.
