Removing Weeds and Moss From Between Patio Pavers for Good
Weeds and green moss are sprouting up through the gaps between your patio pavers, making the surface look neglected and slippery in spots.
Weeds and moss take hold in paver joints because dirt, organic debris, and washed-out joint sand collect there and hold moisture. Pulling the visible growth is only part of the job; the joints need to be cleared and then refilled, ideally with polymeric joint sand that locks together and resists new growth. Addressing why the joints stayed damp and dirty is what keeps the weeds from simply returning.
How the job is done
- 1
Remove the visible growth
Weeds and moss are pulled or scraped out of the joints, getting the roots where possible so they don't simply regrow from what's left behind.
- 2
Clear and clean the joints
The gaps are scraped and swept out to remove old contaminated sand, soil, and debris that hold moisture and feed new growth.
- 3
Treat stubborn moss and roots
Remaining moss and root traces are treated and the joints are allowed to dry, so the surface starts clean before any new sand goes in.
- 4
Refill the joints with sand
Fresh joint sand, often polymeric sand that hardens, is swept into the gaps and packed so the joints are full and stable rather than open to dirt.
- 5
Set the sand and clean the surface
Polymeric sand is activated per its instructions and the paver faces are swept and rinsed clean so no haze is left and the joints lock in place.
What a pro checks
- Pulls roots, not just the tops, so weeds don't immediately regrow
- Clears old contaminated sand and soil that hold moisture in the joints
- Treats lingering moss so it doesn't re-establish in the damp gaps
- Refills joints with sand, often polymeric, to crowd out new growth
- Packs the joints full so dirt and seeds can't easily settle back in
- Activates polymeric sand correctly so it hardens and stays put
- Cleans paver faces so no sand haze is left on the surface

Frequently asked questions
Why do weeds keep coming back between my pavers?
Because the joints collect dirt and organic debris and stay damp, which is the perfect place for seeds to sprout. Clearing the joints and refilling them with proper sand removes that foothold, which slows regrowth a lot.
Is polymeric sand better than regular sand for the joints?
For weed resistance, generally yes. Polymeric sand hardens after it's activated, locking the joints so they shed water and resist new growth better than loose sand, which washes out and lets weeds back in.
Should I just spray the weeds and leave them?
Spraying alone leaves dead growth and open, dirty joints where new weeds quickly take hold. Removing the growth and refilling the joints addresses the cause, so the results last much longer than spraying by itself.
