FAQ

Frequently asked questions
— Brussels

I have no photos and no text, is that a problem?+
No, it’s planned for. We write your copy after a 30-minute call, and photos are included in every plan. If you already have visuals, we use them; if not, we handle it.
What if I don’t like the mockup?+
We rework it. You pay nothing until the design is approved, and you’re committed to nothing before that. If after two attempts it still doesn’t fit, we stop there, at no cost.
Why a subscription rather than a one-off purchase?+
Because a website isn’t a finished object. It has to be hosted, updated, backed up, and its ranking needs work every month. The subscription covers all of it, with no surprise invoice. A site bought once decays quietly: that’s what we find on most tradespeople’s sites we take over.
How much of my time will it take?+
Thirty minutes on the phone, once. Then you approve the mockup, and that’s it. We ask you for no photos, no text and no meetings.
How much does a website cost in Brussels?+
Our plans start at 29 €/month all-inclusive: domain, hosting, content, local SEO and a monthly position report. Pro at 59 €/month, Entreprise at 99 €/month. 12-month commitment, no setup fee.
How long does it take to build a website in Brussels?+
7 to 14 days depending on the project, after design validation. For an application or an online shop, the timeline is discussed in the brief depending on the scope.
Will the website rank well in Brussels on Google?+
Yes. Every website is optimized for local SEO in Brussels: title/meta tags, LocalBusiness schema, Core Web Vitals speed and Google Business profile.
Do I keep ownership of my website?+
Yes. The code, the design and your domain name are yours from day one. The subscription covers the service around it: hosting, technical updates, monthly reports, help with your Google position and support.
Can I change my plan later?+
Yes. You can upgrade at any time. A downgrade is possible at the end of the period.
Will my website be secure?+
Yes. Every site includes an SSL certificate, HTTPS connection and regular security updates.
How does the process work in practice?+
Simple: you contact us → we define your needs → mockup within 48h → validation → online in 7 days.
Do you offer support after delivery?+
Yes. Every plan includes monthly support (email + call if needed) for any question or edit.
Do you work in Brussels?+
Oui. Castelain Digital helps freelancers and SMEs in Brussels build their professional website.
