How often should I have my house washed?

Most Metro Detroit homes benefit from a professional house wash once a year, though homes in shaded or humid areas with heavier algae growth may need cleaning every six to eight months to stay ahead of buildup.

Will pressure washing damage my siding?

High-pressure washing can damage vinyl and aluminum siding by forcing water behind panels or stripping paint. That's why we use soft washing on siding — it's low-pressure and uses cleaning solution to do the work, so your siding gets clean without the risk.

Can you clean a garage door without damaging the paint or finish?

Yes. We adjust our pressure and cleaning solution based on the garage door's material and finish, so steel, aluminum, wood, and composite doors are all cleaned safely.

Does house washing remove black streaks and green algae?

Yes. Soft washing is specifically formulated to break down and remove algae (often appearing as black streaks or green staining) rather than just rinsing it, which means the buildup doesn't come right back in a few weeks like it would with a plain water rinse.

Can brick walls be pressure washed?

Brick can be cleaned effectively, but it requires the right pressure and technique to avoid damaging mortar joints. We assess each brick surface and use a method that removes embedded dirt and algae safely.

We use soft washing rather than high-pressure washing on siding because high pressure can force water behind siding panels, strip paint, and even crack vinyl. Our method gets siding cleaner and keeps it safer.

Garage Door Cleaning

Garage doors collect road grime, oxidation, dirt, and algae just like the rest of your home's exterior — and because they're one of the largest visible surfaces on your house, a dirty garage door drags down your whole curb appeal. We safely clean garage doors of all materials, including steel, aluminum, wood, and composite, removing built-up grime and restoring a like-new appearance without scratching the finish.

Fence Cleaning

Wood, vinyl, and chain-link fences all develop algae, mildew, and dirt buildup over time, especially in shaded yards or near sprinkler systems. We clean fences of every material using the appropriate pressure and solution for that surface — gentle enough to protect wood fibers and vinyl finishes, but strong enough to fully remove green and black staining.

Brick Wall Cleaning

Brick is porous, which means it absorbs dirt, algae, and mildew deep into the surface rather than just sitting on top of it. Our cleaning process lifts embedded grime out of brick walls, retaining walls, and brick accents without eroding mortar joints or damaging the brick face — bringing back the true color of your brick rather than leaving it looking faded or patchy.
