How to Get Rid of Moss on a Driveway

Moss is a common issue on driveways across the UK, particularly in damp or shaded areas where moisture lingers. Although it may not seem harmful at first, moss can become slippery when wet, making driveways hazardous to walk on. Over time, it can also damage the surface of paving, tarmac, or concrete by trapping moisture and encouraging cracks. For homeowners, keeping moss under control is not only about appearance but also about safety and preventing long term maintenance costs. Understanding the best ways to remove moss and prevent it from returning can save both effort and money.

What causes moss to grow on driveways
Driveways provide an ideal environment for moss when they remain shaded and damp for much of the day. North facing driveways, or those covered by overhanging trees or hedges, tend to suffer most. Poor drainage can make matters worse by leaving water to sit on the surface for long periods. Small gaps between paving stones or cracks in tarmac can also give moss a foothold. Unlike weeds, moss does not have roots, but it clings to surfaces and spreads through spores carried by wind or water. Once established, it can multiply quickly and become difficult to control if left untreated.

Manual removal of moss
One of the simplest ways to deal with moss is by physically removing it. A stiff bristle broom or a wire brush can be used to scrape moss from the surface, particularly between paving slabs. This method requires some effort but is effective for small areas or light growth. For block paving, it is useful to brush moss out of the joints before reapplying kiln dried sand to keep the blocks stable. Manual removal may not eliminate moss spores entirely, but it provides a clear surface ready for further cleaning or treatment.

Using water and cleaning solutions
After brushing away moss, many homeowners turn to water based cleaning to finish the job. A bucket of warm water mixed with washing up liquid can help loosen stubborn patches. Pour the solution over the affected area, leave it for a short while, and scrub again with a brush. For heavier infestations, white vinegar diluted with water can act as a natural cleaning solution. It is best to apply it on a dry day, allowing it to soak in before rinsing away. This method is inexpensive and avoids the harsher chemicals found in some commercial products.

Pressure washing as a solution
Pressure washing is a popular option for removing moss from driveways, as it lifts growth from the surface and washes away dirt at the same time. A domestic pressure washer can be highly effective, although it is important to use the correct setting. Too much pressure can damage block paving by removing jointing sand, or strip away the surface of concrete and tarmac. The best approach is to use steady, controlled movements and hold the nozzle at a slight angle. Once finished, block paving should be re sanded to keep it secure. Pressure washing provides an instant improvement, but moss may return if conditions remain damp and shaded.

Commercial moss control products
There are various moss killing treatments available from DIY and garden stores, usually in liquid form. These are sprayed or poured onto the driveway and left to work over several days. Most products break down moss so that it dries up and can be brushed away. When choosing a treatment, check whether it is safe for pets and plants, as some formulas are strong. Always follow instructions carefully and avoid using products before heavy rain, as this will reduce their effectiveness. Commercial products can provide longer lasting results than brushing or water alone, especially when combined with preventative measures.

Eco friendly alternatives
For those who prefer to avoid chemicals, there are natural ways to discourage moss. Baking soda sprinkled over damp moss can dry it out over time, although it may need repeat applications. Salt water solutions have a similar effect, but care should be taken not to allow salt to run off into garden soil where it could damage plants. Another method is boiling water, which can be poured directly onto moss patches, although this is more suitable for smaller areas. These options are safe, inexpensive, and worth trying before investing in specialist treatments.

Preventing moss from coming back
Once moss has been removed, the challenge is keeping it away. Improving sunlight and air circulation can make a big difference. Trimming back overhanging trees and hedges allows the driveway to dry out more quickly. Clearing leaves and debris also prevents damp conditions that moss thrives in. Ensuring proper drainage is important too, as standing water creates an ideal environment for moss growth. On block paving, regularly brushing in kiln dried sand helps reduce gaps where moss can settle. For tarmac and concrete, applying a driveway sealant not only protects the surface but also makes it harder for moss to take hold.

Cost of moss removal and treatments
The cost of dealing with moss depends on the chosen method. Manual removal with brushes is the cheapest approach, requiring little more than tools most homeowners already own. Pressure washers cost from around £80 to buy, or they can be hired for £30 to £50 per day. Commercial moss treatments typically range from £10 to £25 per container, enough to cover an average driveway. Professional cleaning services are also available, with costs starting at around £150 for a standard sized driveway. While this is a higher expense, professionals often use specialist equipment and sealants to deliver longer lasting results.

When to call in professionals
If moss is widespread or the driveway is particularly large, hiring professionals may be the most practical option. Professional cleaners use industrial pressure washers, rotary cleaners, and commercial grade moss treatments that are more effective than domestic alternatives. They also re sand or seal driveways as part of the service, reducing the chance of moss returning. For homeowners who want a quick and thorough solution without the hard work, this option is often worthwhile, especially when combined with routine maintenance to keep the driveway looking its best.

Final thoughts
Getting rid of moss on a driveway requires effort, but there are several effective methods to choose from. Manual scrubbing, natural cleaning solutions, pressure washing, and commercial treatments all have their place, depending on the size of the problem and the surface material. Preventing moss from coming back is just as important as removing it, and simple measures such as improving drainage, trimming plants, and regular brushing can make a lasting difference. By tackling moss early and maintaining the driveway, homeowners can enjoy a cleaner, safer, and more attractive entrance to their property.
