Questions
Questions we get asked
When is the best time of year to power wash a driveway?
Late spring and early summer. At Shannon Airport, April, May and June have the most dry days, about 14–15 a month against 8 in November, and there's no air frost on average from May to September. The clean itself works in any month; re-sanding and sealing need a dry spell.
Can you power wash in winter?
Yes. The clean works in any month. Winter makes the drying harder: re-sanding and sealing need a dry surface, and Shannon Airport averages 5.2 days of air frost in January. Water left on a path on a frosty night can ice over.
Is it worth power washing in autumn?
Often, yes. Leaves and a wet summer leave paving green and slippery before winter. October still has about 11 days without rain at Shannon Airport.
Is it cheaper to book in winter or midweek?
Sometimes. Companies are less busy then, so ask whether there's a better price for an off-season or midweek slot.
How long after power washing can I re-sand or seal?
Once the paving is fully dry. In a dry spell that's often the same day or the next; the company will tell you.
