A concrete slab, an asphalt surface and an interlocking paver driveway don’t clean the same way. Concrete generally handles higher pressure; asphalt needs a gentler pass; interlock is the most delicate, since too much pressure blasts polymeric sand out of the joints.
The City salts and sands roads through winter, and many homeowners salt their own driveways too. We lift that residue, not just visible stains.
Concrete, asphalt and interlock sections on the same driveway each need a different pressure and approach.
Too much pressure blasts polymeric sand out of interlock joints. We avoid that entirely.
Hot water and the right cleaning agent break down oil, tire marks and organic staining.
Concrete, asphalt and interlock each get pressure and technique suited to that material.
We avoid blasting polymeric sand out of paver joints while cleaning interlock.
Removing dirt and residue first means sealer bonds properly instead of trapping grime underneath.
We check the driveway's material, then confirm a written price before booking.
We set pressure by material: higher for concrete, gentler for asphalt and interlock.
We clean the surface and finish with a rinse that clears residue, not just the visible stain.
We check the finished driveway with you before we leave.
Capital Wash & Seal provides professional driveway cleaning throughout Ottawa and the surrounding area. Concrete, asphalt and interlocking paver driveways all collect the same layers of grime over an Ottawa winter and summer: oil and tire marks, tracked-in dirt, tree sap, and the chalky residue left behind by de-icing salt and calcium chloride. We use hot water pressure washing with a surface cleaner attachment to lift that buildup evenly across the full driveway, adjusting pressure and technique for whichever surface we're working on so we clean the driveway without eroding polymeric sand from paver joints or etching a concrete slab.
Hot water pressure washing lifts most surface oil and tire staining. Deep-set or older oil stains may lighten significantly rather than disappear completely, depending on how long they've been there.
Not when it's done at the right pressure. We avoid blasting polymeric sand out of paver joints, which is the main risk with interlock and something a generic high-pressure pass can cause.
Yes. Sealer needs a clean surface to bond to, so we always clean first, whether cleaning is part of a sealing job or requested on its own.
Asphalt is softer and needs a gentler pass, while concrete can generally take higher pressure and benefits from a surface cleaner attachment that clears streaking evenly.
Most driveway cleaning jobs run $150 to $850 depending on size, surface material and how much buildup there is, always confirmed with a written quote first.
Most Ottawa driveways benefit from a cleaning once a year, typically in spring after winter salt and sand have built up, though a shaded or heavily used driveway may need it more often.
Rust stains from patio furniture or vehicles respond to a targeted rust-removing treatment in most cases, applied alongside the regular cleaning pass.
Yes, garage floor cleaning can be added to a driveway visit, and we'll quote both together so you get one appointment instead of two.
