Your Questions Answered

How often should I schedule house washing for my home?

Most homeowners schedule house washing about once a year. This keeps dirt, mold, mildew, and grime from building up on your siding and exterior surfaces. If your house is in a damp area or surrounded by trees, you may need cleaning more often. Staying on a regular schedule helps protect your home and keeps it from looking dull over time.

Will pressure washing damage my house?

Pressure washing can cause damage if too much pressure is used or if the wrong spray pattern and nozzle are chosen. That’s why we use the right equipment and adjust water pressure based on the surface, whether it’s vinyl siding, brick, stucco, or wood. In many cases, we use soft washing instead, which relies more on a cleaning solution than high pressure. This approach helps eliminate dirt, mold, and mildew without risking water damage.

What’s the difference between pressure washing and soft washing?

Pressure washing uses high water pressure to clean tough surfaces like concrete or a deck. Soft washing uses lower pressure along with a detergent or chemical mixture that sits (or “dwells”) on the surface to break down dirt, algae, and mold. For most homes, especially vinyl siding or painted surfaces, soft washing is the safer and more effective process.

Do I need to be home during the cleaning service?

No, you don’t need to be home. As long as we have access to water and the areas we need to clean, we can handle the job from start to finish. We’ll take care of your house, rinse everything properly, and make sure windows, siding, and surrounding areas are left clean and in good shape.

Is house washing safe for plants, pets, and landscaping?

Yes, when done correctly. We take steps to protect your plants and nearby areas by rinsing them before and after cleaning. The cleaning solutions we use are safe when handled properly, and we control how the liquid is applied so nothing harmful sits too long. We’re always aware of your landscaping and treat it with care.

Can I just use a garden hose, or do it myself?

A garden hose can help rinse light dust, but it won’t remove deep grime, mold, or oxidation. Using a pressure washer without the right equipment or knowledge can lead to damage, especially if the pressure setting is too high. You could end up forcing moisture behind siding or damaging wood and vinyl. Hiring a professional ensures the job is done safely and efficiently.

How long does the house washing process take?

Most house washing jobs take a few hours, depending on the size of the home and how much buildup is present. We take our time to clean every surface properly, allowing the detergent to dwell where needed and making sure everything is fully rinsed. The goal is to do the job right, not rush through it.

What should I do to prepare before you arrive?

Before we arrive, close all windows and doors, move small items away from the exterior, and make sure we have clear access around the house. If you have outdoor furniture, grills, or décor, it’s helpful to move or cover them. We’ll handle the rest, including protecting sensitive areas and making sure everything is cleaned safely
