Key Information
- A clean and seal for a standard double driveway usually runs $1,300–$1,600 (based on available market estimates; tailored quotes give a more accurate price).
- Price depends on surface type, size and condition. Preparation and the type of sealer used also play a part.
- Most operators have a minimum job charge. A small driveway won’t cost much less than a mid-sized one.
- Sealer needs a clean, dry surface to bond. Booking cleaning and sealing together is usually better value. A quality penetrating sealer lasts longer between reseals, which also lowers the cost over the life of your driveway.
Perth operators usually price driveway sealing per square metre, as a flat rate for set driveway sizes, or with a minimum job charge for smaller areas. As with the cost of just cleaning a driveway, it pays to check what’s included before you choose the cheapest of the bunch.
A low sealing rate often covers the sealer application only. Pressure cleaning, oil or bore stain treatment, and stripping of any old sealer are then added on – so the advertised price and the final invoice can look quite different. Getting a tailored quote for your job is much more accurate, as it covers everything that needs to be done.
Here’s a guide to what Perth homeowners can expect to pay, by surface and by whole job:
| Surface / Job Type | Estimated Cost |
| Concrete (plain and coloured) | $5–$15 per m² |
| Exposed and honed aggregate | $12–$20 per m² |
| Pavers | $14–$22 per m² |
| Limestone (pavers and liquid limestone) | $10–$18 per m² |
| Small driveway, clean and seal (up to around 50m²) | $900–$1,000 |
| Standard double driveway, clean and seal (around 80–100m²) | $1,350–$1,600 |

What affects the cost of sealing a driveway?
A few main factors will move your quote up or down within the market range. We always recommend getting your driveway professionally pressure cleaned before sealer is applied, as you will need to remove dirt, build up, and any old sealer before the new one can go down.
Surface type
Every stone surface takes sealer differently. Plain concrete is generally the simplest to seal. Coloured concrete may need a colour-enhancing product to stay vibrant under Perth’s UV. Exposed and honed aggregate need a sealer that protects without clouding the stones.
Natural stone pavers have joints to consider as well as the faces. Limestone and natural stone are more porous. They need a breathable sealer suited to the specific stone, and an experienced applicator to ensure the best possible finish.

Size and layout
Larger driveways usually cost less per square metre as setup and travel are spread across a bigger area. That’s why smaller jobs often hit a minimum charge, even if the square metreage is lesser; it’s to cover those same setup costs, which don’t really change. Curves, slopes, narrow side paths and tight access may also add time to a job.
Preparation and cleaning
Sealer can only bond to a clean surface. Anything left behind (dirt, oil, mould, tyre marks) gets locked in under the seal. Poor bonding shortens the life of the sealer, making it more likely to fail before replacement would usually be required.
A thorough pressure clean is the first step of any sealing job. If it isn’t included in your ‘fixed price’ quote, expect it to add around $150–$350+ for a Perth driveway.
Stains and old sealer
Oil stains, hot tyre marks and bore stains need treating before sealing; old sealer will need to be cleaned off as well, so the new one can penetrate the stone (or properly adhere if you are really keen on a film-forming sealer). A custom quote will take these factors into account so you don’t have any surprises at the end.
Type of sealer
Sealers vary a lot in price and performance. Your choice affects both the upfront price and how soon you’ll need to reseal. We can advise you on what is the best sealer for your driveway, taking into account the stone, conditions, and desired finish.
How the cheapest sealer can cost you more
Driveways are one of the hardest-working surfaces around your home. Many cheaper sealers form a film on top of the surface, a bit like paint. Under wear and tear, the weight of vehicles, and Perth’s harsh environmental conditions, they can lift and peel. Your driveway can end up looking patchy within just a few years. The failed film sealer then has to be stripped before resealing, which adds to your next bill.
Penetrating sealers soak into the surface and bond within it, meaning there’s no layer at risk of peeling. That’s why we use a penetrating sealer for driveways; it lasts much longer between reseals, with no stripping needed.
Spread across the lifetime of the product, a high-quality penetrating sealer usually works out cheaper over time – especially in the hands of an expert, fully insured operator. Inexperienced or uninsured operators can be cheaper, but the ‘pay cheap, pay twice’ rule applies. You often end up having to hire someone else to fix a lacklustre result.
When is the best time to seal a driveway in Perth?
That depends on the sealer used. The water-based penetrating sealer we use is applied to wet pavement. In fact, the wetter the surface, the better our Guard Industry sealer penetrates and bonds. It goes on straight after the pressure clean; no more waiting days for the driveway to dry first. That means sealing is an option year-round, not just in dryer months.
Solvent-based sealers are different. They need a completely clean, completely dry surface and suitable weather. If moisture is trapped underneath, the sealer can turn cloudy or peel. Application can take several days, depending on conditions.
Whichever sealer is used, give it the manufacturer-recommended time to fully cure. With our water-based sealer, you should stay off the surface completely for the first 24 hours. Full cure can take up to 72 hours, so keep cars and anything else heavy off the driveway for 3 days.
How often do you need to reseal your driveway?
It depends on the surface, the sealer, the traffic and how much direct sun the driveway cops. A quality water-based penetrating sealer can give some level of protection for up to 10 years. For the best protection, we recommend resealing every 3–5 years. Busy driveways and harsh, exposed spots may need it closer to every 3 years.
Resealing a well-maintained driveway is usually cheaper than the first seal, especially if no stripping is needed. A few simple habits help stretch the time between reseals:
- Pressure clean once a year to shift built-up dirt and grime.
- Clean up oil and other spills quickly.
- Use warm soapy water and a soft brush for general cleaning.
- Avoid harsh chemicals, acids and abrasive scrubbers.
Can you seal a driveway yourself?
We wouldn’t advise it. Applying sealer evenly over a whole driveway is harder than it looks.
Many retail sealers need a bone-dry surface and the right run of weather. Apply it too thick, too thin or in the wrong conditions, and you can end up with streaks, cloudy patches or peeling. At that point, the driveway needs professional stripping and resealing. That often costs more than just getting it done properly the first time.
Note: If you DIY, use appropriate protective gear and take all recommended safety measures. Always follow the manufacturer’s directions for any sealer or chemical treatment.
