How do I remove construction dirt and tire marks from a new driveway in Ottawa?

Construction dirt and tire marks on a new driveway are a frequent post-construction headache, and the approach you take depends entirely on what your driveway is made of and how long it has been cured. Jumping straight to aggressive pressure washing on a fresh surface can cause real damage, so understanding the right timing and technique is critical before you start cleaning.

Cleaning Methods by Driveway Type

For poured concrete driveways, the most important consideration is cure time. A commonly cited rule of thumb is to wait at least 28 days before pressure washing new concrete, and longer in cool weather — the company that poured it can tell you when it is ready. During that initial cure period, you can gently sweep loose dirt with a push broom and rinse with a garden hose, but avoid high-pressure equipment. Once properly cured, concrete can handle pressure washing with a fan tip. Tire marks on concrete often respond to a degreaser left to sit for a few minutes before washing. Dried clay-heavy mud can stain concrete and sometimes needs a concrete-safe cleaner to fully remove.

For asphalt driveways, be much more cautious. New asphalt needs time to harden, so ask the paving company how long to wait before any pressure washing. Even then, keep the pressure low and use a wide-angle tip to spread the force across a larger area. Tire marks on fresh asphalt are often cosmetic and tend to fade as the surface weathers. If construction dirt is sitting on new asphalt, a garden hose and soft-bristle broom are your safest tools for the first season.

For interlock and paver driveways, pressure washing is generally fine once the polymeric sand has fully cured — the sand product's instructions give the cure time. However, too much pressure or holding the wand too close can blast the sand out of the joints. Keep the pressure moderate and the wand at a consistent distance from the surface. You may need to re-sand the joints after cleaning.

Quotes for driveway cleaning after construction in Ottawa can run roughly $200 to $500 depending on driveway size and material — ask for itemized written quotes to know your price. It can be money well spent on a new driveway, because the wrong technique can cause surface damage that costs far more to repair, and some manufacturers' warranties have care instructions worth checking first.
