Interlock Cleaning in Gatineau
High-pressure washing to remove moss, stubborn stains and debris. Flawless results in a single day.
Our Cleaning Process
Every job follows our rigorous steps to restore your stone's original beauty
Free Evaluation
We assess the condition of your pavers and give you a detailed on-site quote with no obligation. It's always Émile or Beckett in person — never a subcontractor — giving you a fair price, no surprises once the work starts.
Anti-Moss Pre-Treatment
We apply a targeted, biodegradable degreasing product to break down moss and stubborn stains. We always protect the lawn and flower beds around the area before applying anything.
High-Pressure Wash
Removal of all dirt, moss, lichen, debris and stubborn built-up organic matter. Our professional pressure washer (3600 PSI, 2.5 GPM, industrial Honda engine) lifts deep-set grime without damaging your pavers.
Final Rinse
A complete rinse of the surface, a thorough inspection of the area and careful cleanup of the job site. We pick up and carefully clean every adjacent surface before we leave — there's nothing left for you to do.
Signs It’s Time to Clean Your Interlock
The freeze-thaw cycles and big temperature swings in Gatineau and Ottawa create moisture that brings out moss and lichen between the joints. Here are the most common signs we notice at our customers' homes:
- Greenish moss or lichen settling between the joints, especially in shaded corners.
- Black or greyish stains caused by organic grime building up over time.
- The pavers lose their original colour and look dull, even with minimal upkeep.
- Ants are settling into the gaps, even if the sand hasn't degraded yet.
- The surface gets slippery or smells musty after rain.
- Whitish residue left behind by winter de-icing salt.
If that's all you're seeing — no shifting or sinking pavers — a good cleaning usually solves the problem, no full repair needed.

What Our Customers Say
In the words of a few of our customers.
Why Not Wait to Clean Your Interlock
The longer you wait, the deeper dirt, moss and weeds work their way into the joints. With the freeze-thaw cycles we get here every winter, moisture trapped in a neglected joint speeds up this buildup year after year. Regular cleaning every 2-3 years costs far less than the full repair that becomes necessary once the polymeric sand is completely degraded. Maintaining your interlock pavers now means avoiding bigger — and pricier — work later: our projects typically range between $600 and $4,000 depending on the scope of work required.
