Will A Pressure Washer Remove Weeds?

If you have a house with “curb appeal”, a new car on the driveway, and the perfect magazine style image it can feel like you’ve got it made. But if you look closely, all is not what it seems, why? Weeds! Let’s face it weeding is a thankless task, as soon as you remove them, they’re growing back again, it can be quite demoralising.

On your hands and knees pulling weeds, from the cracks in the driveway, where the brick walls start and the drive ends. It’s even worse if you have block paving, weeds love those sanded gaps between stones. It seems like one lot is already starting to sprout as you remove the lot before.

Not any more, we have the perfect solution – pressure washing. By pressure washing the driveway, you will remove those unwelcome plants and give you your spotlessly clean driveway back. Plus if you take the time to seal the driveway after pressure washing, you can prevent new weed growth from appearing at all.

Why Remove Weeds From Driveways?

There are other benefits to using a pressure washer to remove weeds from the driveway. It’s not just about “kerb appeal”, other benefits include:


 Weeds, algae and moss make your drive a much more slippery surface. This can be dangerous for driving and walking. Plus weeds act as a trap for litter. Paper and plastic bags blow in the wind and can get trapped in the weeds on your driveway.


This is not only an eyesore, but it is also a harbourer of germs and bacteria and unwanted litter can attract all kinds of rodent life to the property too. Rats, mice, and many other creatures can take up residence if you allow litter and waste to build up on your drive. 

Cleaner Drive

If weeds and moss are allowed to grow, dust blown in by the wind will build-up making the driveway dirtier quicker.

Energy Efficient

A half-hour session removing weeds and pressure washing your driveway will keep weeds, dirt and debris away for months. On average it takes a quarter of the time to clear a driveway using a pressure washer compared to using a hose and brush. It also saves up to 80% of the water you would use by washing the drive with a hose.

Save Time And Money On Maintenance

Allowing weeds to grow unchallenged can lead to cracks and splits forming in your drive that will need time and money to repair. 

Enhanced Property Value

By keeping your drive weed and moss free, you add that all-important “kerb appeal”, that adds value to your property price. It is estimated that clean and tidy driveways and entrances can add between £5,000 to £10,000 to the resell value of your home.
