Our Property Protection Process

How do we keep your property safe during exterior cleaning?

If you’re thinking about having your home soft washed, pressure washed, or otherwise cleaned on the outside, one of the first questions that probably pops into your head is: “What could go wrong?”

You’re not alone. We hear this concern all the time. Strong cleaning solutions, high pressures, and high flow water can cause real problems if the job isn’t approached with healthy caution. That’s why property protection isn’t something we tack on at the end — it’s a fundamental part of our entire process.

Every property is different. A heavily landscaped yard with mature plants and bronze fixtures requires a different approach than a newer home with mostly hardy shrubs. While no process on earth can promise zero risk in every single scenario, we’ve built a thorough, repeatable Property Shield Process that dramatically reduces the chance of damage and gives you real peace of mind.

Here’s exactly how we do it.

Protecting Your Plants

Plants are often the most vulnerable part of any job. Cleaning chemicals (especially those used in soft washing) and overspray can burn foliage, damage roots, or stress grass if they’re not managed properly.

Here’s what we do on every job:

• Pre-job walkthrough: we start with a careful pre-job walkthrough to identify every plant, shrub, flower bed, tree (I'm looking at you Japanese Maple), and grass near the work area.
• Pre-saturate: we saturate the grass and flower bed before beginning work, topping off the plants thirst so they limit the amount of chemicals they drink up.
• Cover: Sensitive or high-value plants are covered with breathable sheeting where needed.
• Control: we use low-pressure techniques and careful directional spraying to minimize overspray and direct contact.
• Running Protection: when the project calls for it, a dedicated team member handles ground-level rinsing during and after the job to keep chemicals diluted and plants flushed.
• Final Rinse: we always do a final rinse of plants and surrounding soil to dilute anything that got near the plants.

If you have particularly delicate or expensive landscaping, just let us know during the walkthrough. We’ll flag it and take extra precautions.

Securing Points of Entry

Water finding their way inside your home is one of the fastest ways to turn a good cleaning job into a nightmare.

Our standard protocol includes:

• A full inspection of all windows, doors, vents, electrical outlets, light fixtures, HVAC intakes, dryer vents, and any other openings or penetrations.
• Professional masking using heavy-duty plastic sheeting, high-quality painter’s tape, and (when appropriate) specialized protection products.
• Sealing gaps around outlets, light boxes, and gaps in trim or siding.
• A final walkthrough after the job to remove all protection materials and double-check that everything is clean and dry.

An ounce of prevention is worth a pound of cure.

Our Personnel Protocols

Great protection doesn’t happen because of good intentions — it happens because of trained people following a clear system.

Here’s how our team operates:

• Every technician goes through specific training on our property protection standards and checklists before they ever step on a job site.
• We hold a pre-job briefing on every property to review exactly what needs protecting and who is responsible for each area.
• We work in coordinated teams with clear communication. If something looks risky or the conditions change, we pause and reassess.
• All technicians are fully insured and expected to treat your home with the same care they’d want shown to their own.
• We document pre-existing conditions with photos when it makes sense, so there’s never any question about the state of your property before we started.

Protection is a mindset, not just a task. Our people are trained to think that way on every single job.

Protecting Particular Surfaces

Some surfaces simply don’t play well with strong chemicals or high pressure. Stained wood, bronze hardware and fixtures, decorative metalwork, certain light fixtures, old mortar, are examples of surfaces that can be permanently discolored, etched, or stripped if cleaning solution is allowed to sit on them or if the wrong technique is used.

This is how we handle particular surfaces:

• During our initial property assessment we specifically look for and document high risk surfaces.
• We apply targeted protection — custom masking with tapes and films that won’t damage or leave residue on those surfaces.
• We often switch to gentler cleaning methods, hand-brushing, or alternative solutions in areas right next to these features.
• Chemical application is precisely controlled. We never spray directly at or allow prolonged contact with unprotected sensitive surfaces.
• When we’re unsure about a finish, we test in a small, inconspicuous area first.
• After the job we do a final inspection to make sure all protection has been cleanly removed and the surfaces look exactly as they should.

We’d rather take a little extra time and use the right method than risk damaging something that matters to you.

The result of this process? A thoroughly cleaned property with dramatically lower risk of damage — and a lot less stress. We built this level of protection into our service because we believe that’s what professional exterior cleaning should look like.

Frequently Asked Questions

Q: Will my plants be okay?
A: In the vast majority of cases, yes — especially when we follow the steps above. We pre-wet, cover where needed, rinse thoroughly, and adjust our approach based on what’s growing on your property. If you have anything particularly rare or valuable, we’ll discuss it upfront and take extra measures. If something is harmed because of us, we will always replace it.

Q: Do you really cover all the openings?
A: We do. We inspect every potential point of entry and mask accordingly. It takes time, but it’s non-negotiable for us.

Q: What about my stained front door and bronze fixtures?
A: These are exactly the kinds of “particular surfaces” we flag during the walkthrough. We mask them properly and often use gentler techniques right around them so they stay looking great.

Q: What if something does happen?
A: We carry full insurance and stand behind our work. That said, our entire protection process is designed to make damage extremely unlikely. We’d much rather prevent issues than deal with them after the fact.

If you’d like us to walk your property and show you exactly how we’d protect it during a cleaning, just reach out. We’re happy to do a no-pressure (get it?), free assessment and answer any questions specific to your home.

Your property deserves to come out of this looking better — not damaged. That’s the standard we hold ourselves to on every job.
