Where they stood

Hogedruk.be was a new company, but not new craftsmen. The people behind it have known for years how to clear moss from a roof without damaging the tiles, how to clean a driveway without blasting the pavers loose, and when softwash beats high pressure. That craft simply did not exist digitally: no logo, no brand, no website, no visibility.

That is a harder starting point than it looks. An established company with a dated site at least has name recognition, customer reviews and years of mentions across the web. A new brand has none of that, and neither search engines nor language models have any reason to name it.

What we did

Build

Everything. Colours, logo, the complete brand identity. The livery on a van and on a trailer carrying the cleaning equipment, because in this trade a moving vehicle is an advertisement. And the website, built around the four surfaces people search for: roof, façade, driveway and terrace.

Fill

The content is written around the questions people actually ask, and those are more often informational than commercial. Is high pressure bad for pavers? How do I remove green growth from my driveway? How do I make a driveway less slippery? Those are the questions of someone who does not yet know they need a specialist. Whoever answers them gets there before the competitor who only targets "driveway cleaning Antwerp".

Convert

One clear route to a free quote, with a form that immediately asks which surface is involved and where the property is, so nobody needs three emails back and forth first.

What came out

The site went live in mid-March. The first enquiries arrived within two weeks. For a brand that did not exist digitally a month earlier, that is the only number that matters at that point.

What happened next is more remarkable. Within four months, Hogedruk.be is the most visible company in AI answers in the exterior cleaning market around Antwerp: by a wide margin.

Where we are now

Visibility is there; reputation is the next step. Language models base their judgement on what is written about a company, and a brand a few months old simply has little of that yet. That is what we are working on.
