Our method
Clearing Growth From Sidewalks and Walkways
A shaded, narrow walkway holds moisture longer than an open driveway, which is why algae and moss often show up there first. We match the cleaning pass to the material, concrete, interlock or natural stone, and rinse it clear rather than leaving residue behind.
What Sidewalk and Walkway Cleaning Fixes
Shaded Walkways Hold Moisture
A narrow, shaded walkway holds moisture longer than an open driveway, which is why algae and moss show up there first.
Slippery, Unsafe Surfaces
Built-up grime and moss make a walkway more than just dirty, they make it slippery. Cleaning addresses both.
Joint Sand on Interlock Paths
We're careful with pressure around interlock joints so we don't erode the sand that keeps the path stable.
What Our Walkway Cleaning Covers
Slip hazard removed
Algae and moss buildup that makes a wet walkway slippery is cleared, not just rinsed lighter.
Joint sand protected on interlock paths
Pressure is controlled around paver joints so sand stays in place.
Entrances and commercial walkways
We clean front entrances for homes and businesses, where first impressions matter most.

Final Walkthrough
We check the finished walkway with you before we leave.
Capital Wash & Seal provides professional sidewalk and walkway pressure washing throughout Ottawa and the surrounding area. Front walkways, side paths and entrance sidewalks see constant foot traffic and often get less sun than a driveway, which is exactly the combination that lets algae, moss and mildew take hold on concrete, interlock and natural stone paths. Beyond looking dull, a walkway coated in algae or moss gets slippery when wet, which is a real concern on a path people use every day. We pressure wash sidewalks and walkways with attention to slip hazards, joint sand in interlock paths, and any plantings that line the route.
Sidewalk & Walkway Questions
Why does my walkway get slippery when it's wet?
Algae and moss growth on a shaded, low-light walkway creates a slippery film once it's wet. Pressure washing removes that buildup rather than just knocking down the visible dirt on top.
Can you clean interlock walkways without damaging the joints?
Yes. We control pressure around paver joints so we clean the surface without blasting out the polymeric sand that holds the pavers in place.
Do you clean walkways for businesses, not just homes?
Yes, we clean entrance walkways and paths for commercial properties as well as residential ones, since a clean entrance matters for both.
How often should a walkway be pressure washed?
Shaded or heavily used walkways often need attention about once a year, while sunnier paths may go longer between cleanings.
What does sidewalk and walkway pressure washing cost?
Most walkway cleaning jobs fall in the $150 to $850 range depending on length and surface material, confirmed with a written quote before we begin.
Do you clean shared or condo walkways?
Yes, we take on both single-property walkways and shared or condo walkways, scoped and quoted based on the total area.
Can you clean a shared walkway between two properties?
Yes, we regularly clean shared or condo-association walkways. We're happy to coordinate scheduling and quoting with a property manager or a neighbouring owner if needed.
Do you offer recurring seasonal cleanings for walkways prone to moss?
Yes, a shaded or north-facing walkway that grows moss quickly is a good candidate for a recurring seasonal visit, which keeps it from building up between full cleans.
Do you clean pool decks and patios connected to a walkway?
Yes, pool decks and connected patio areas can be cleaned in the same visit as a walkway, which keeps the whole path looking consistent from front to back.
