Pressure Washing in Prince George, BC

Winter also puts salt and de-icer on concrete, and repeated freeze-thaw drives moisture into it. Washing does not repair spalling that has already started, and we will point it out rather than pretend a clean fixed it.

As on the coast: hard surfaces get pressure, everything else gets soft washed. Siding, painted surfaces and roofs are never pressure washed.

Driveways here are also bigger. A long rural driveway on the outskirts is several times the area of a suburban one on the coast, and grit covers all of it, so this is a job measured by the hour rather than by the afternoon.

One thing worth saying plainly: a spring wash makes existing concrete damage obvious for the first time all year. Grit hides a lot. If your driveway has been quietly spalling under the winter dirt, this is when you find out, and we would rather point it out than wash over it.

Salt residue and damaged concrete are not the same thing. Surface residue can be loosened and rinsed away; flaking paste, exposed aggregate and scaling are changes in the slab itself. More pressure will not put that material back, and it can make a weak patch worse, so the condition of the concrete has to be read before the machine is turned up.

The work window is practical as well as seasonal. Water running across a driveway needs time to drain before the temperature drops, especially on shaded sections that hold cold after the rest of the property has warmed. A bright afternoon is not enough if the same surface will freeze again that evening.

Spring grit also hides joints, low spots and old repairs. Once the surface is rinsed, those features control where the dirty water travels and where it pools. Planning the passes from the high side toward a safe outlet matters more on a long Prince George drive than simply beginning at the garage and pushing everything toward the road.
