How Are Weeds Removed From Driveways During Cleaning?
Driveway weeds grow in the joints, not through the blocks. Here is how a proper clean removes them at the root and stops them coming back.
Weeds in a driveway look unsightly and can make even an expensive surface seem neglected. The good news is that, on block paving, weeds rarely grow through the blocks themselves. They germinate in the dust and debris that collects in the joints, which means the long-term fix is more about the joints than the weeds.
This guide explains how weeds are removed from driveways during cleaning, why simply pulling the tops off does not work and how a proper clean tackles the root cause so they are slower to return.
Why weeds grow in driveways
Wind-blown seeds land in the joints between blocks and germinate in the thin layer of dust, soil and organic matter that builds up there over time. Empty or washed-out joints, shaded damp spots and accumulated leaf debris all create the perfect seedbed. The weeds root in that debris, not in the solid blocks.
How weeds are removed during cleaning
A professional clean clears weeds and the conditions that let them grow, in sequence.
-
Step 1
Treat and clear
Existing weeds are treated or removed, including the roots, so they do not regrow.
-
Step 2
Deep clean joints
Pressure washing flushes out the weeds, debris and old sand from the joints.
-
Step 3
Re-sand
Fresh kiln-dried sand fills the joints, leaving no gap for seeds to settle in.
-
Step 4
Optional seal
Sealing locks the sand in and helps block seeds from taking hold.
Why pulling weeds alone fails
Snapping off the visible top of a weed leaves the root behind, so it grows back. Worse, leaving the debris-filled joints untouched means new seeds simply germinate in the same spot. Removing the root and clearing the joint of its growing medium is what actually stops regrowth.

Stopping weeds coming back
The most effective long-term defence is full, well-sanded joints, which is why re-sanding matters so much, as we explain in our guide on what block paving re-sanding involves. Sealing adds a further barrier that blocks seeds and is covered in what driveway sealing involves and why it is done. Regular sweeping to keep debris out of the joints also helps a great deal.
Weed treatments and your garden
The treatments used to clear weeds need careful handling so they do not affect your wanted plants nearby. A responsible team protects your borders while working, which we cover in our guide on how cleaners protect plants and surroundings.

Frequently asked questions
How are weeds removed from a driveway?
Existing weeds are treated or removed at the root, the joints are deep cleaned to flush out debris and old sand, then fresh kiln-dried sand is brushed in to fill the gaps.
Do weeds grow through block paving?
Rarely. They germinate in the dust and debris that collects in the joints, not through the solid blocks, so the long-term fix is keeping the joints full and clean.
Why do weeds keep coming back?
Pulling only the visible top leaves the root behind. Debris-filled joints also let new seeds germinate. Removing the root and clearing the joint stops regrowth.
Does re-sanding stop weeds?
Largely, yes. Full, well-sanded joints leave no gap for wind-blown seeds to settle in, which is the best long-term defence against weeds.
Will weed treatment harm my plants?
Not with a careful team. Treatments are handled to avoid your wanted plants. Borders are protected during the work.
