Don’t Be Fooled: The 3 Biggest Exterior Cleaning Scams to Avoid

From the outside, exterior cleaning looks simple.
But beneath the surface? There’s a wild west of shortcuts, shady practices, and dangerous damage left behind by “cheap and cheerful” cowboys.

At MECS, we get called out every week to fix mistakes made by operators who overpromised, underdelivered — and vanished when the problems started.

Here are the 3 biggest red flags you need to avoid — especially if you care about the long-term integrity and presentation of your property.

Scam #1: “We Just Blast It with a Jet Washer”

🚩 Red Flag: They suggest high-pressure washing for everything.

Sounds quick. Looks satisfying.
But it’s the fastest way to destroy roof tiles, chip render, and strip patio jointing.

Professional exterior cleaning uses:

• Steam for roofs

• Softwash biocide for render

• Controlled pressure with the correct nozzles for stone and block paving

Pressure washing your roof or render isn’t cleaning — it’s surface damage with a hose.

Scam #2: “It’s £150 All In — We Don’t Do Quotes”

🚩 Red Flag: Flat pricing with no inspection.

If someone quotes you without looking at your property, you’re not getting a service — you’re buying a gamble.

At MECS, we inspect, advise, and give a fixed price that reflects the surface, access, and finish you expect.
And we never add surprise costs mid-job.

Scam #3: “We’ve Got a Special Chemical Spray”

🚩 Red Flag: No proper explanation of what they’re applying.

We’ve seen it all — acidic brick cleaners used on render, cheap chlorine slapped on patios, harsh fungicides used near gardens.

Not only can this kill plants, strip colour, and erode surfaces, it often voids warranties.

We only use professional-grade biocides, applied with precision — and tailored to the material and environment.

What You Should Expect From a Proper Exterior Cleaning Company:

✔️ Public liability insurance
✔️ Transparent pricing after property inspection
✔️ Proper equipment (not a £60 Karcher off eBay)
✔️ Branded uniforms & vans
✔️ Before/after documentation
✔️ Safe methods tailored to your property

That’s the MECS standard — and it’s why we’re the most reviewed exterior cleaning team in the region.

Final Word:

Don’t let a £100 “deal” turn into a £1,000 repair.

Your property deserves better.
Protect it. Present it. Preserve its value.
