Frequently
Asked Questions

If your landscaping obstructs access, we’ll let you know which areas we can’t safely reach. We never force our way through tight spaces to avoid damaging plants or property. You’re welcome to trim or move anything prior to service to ensure full access.

It depends on the condition of the surface. If we believe cleaning could worsen existing damage, we’ll pause and let you know before proceeding. You may need to schedule repairs first to ensure safe and effective power washing.

If you’re unable to move furniture, we can assist for a small additional fee. Just let us know in advance so we can plan accordingly. We handle all items with care, but we’re not liable for damage if we move them.

The cleaning solution begins breaking down immediately after rinsing and loses effectiveness within a few hours. Any residual solution left behind is diluted and safe after final rinsing, especially with our plant protection measures.

Yes, we offer partial house washing when requested. Keep in mind, cleaning just one side may result in visible contrast with untreated areas.

We don’t power wash during thunderstorms or freezing weather for safety and effectiveness. Light rain is fine, but we always assess the conditions to ensure quality results—especially for roof and oxidation treatments.

If your siding looks chalky or faded, you may have oxidation buildup that a standard wash won’t fix. We’ll assess your surfaces during the estimate and let you know if oxidation removal is recommended.

Spotting can occur if surfaces dry unevenly or if residue is left behind—but we take steps to avoid this. Our rinsing techniques and post-job inspections are designed to catch and correct streaks before we leave.

If local restrictions affect your water supply, let us know in advance. We can bring a portable water tank for an additional fee or reschedule to avoid fines or disruption.
