Questions
Quickly answered
As soon as you enter them. Guide price, room configurator, subsidy calculator and running cost calculator work with a few rules of thumb that live in src/scripts/rechner.ts and in the data files. Your AI enters your prices and rates in one pass, and the prices on the service pages follow.
Yes. The eight services are entries in src/data/leistungen.ts. A new entry creates a complete service page with opening, package contents, process, prices and questions, a deleted one disappears from the menu, overview, finder and footer.
Yes. Services, sectors and calculators are data. A heating firm moves heating and heat pumps to the front, a ventilation contractor duct cleaning and indoor air. The page structure stays the same.
They are checked as of September 2026 and marked with that date on the page. Subsidy rates and deadlines change, which is why they live in data files. Before going live, enter the current values, the copywriting skill says what to watch when advertising subsidies and savings.
No. Company, names, prices, projects, key figures and testimonials are invented for this template and marked as examples on the page. There is deliberately no rating score, not in the structured data either. START-HERE.md says what has to be replaced before going live.
As placeholder pages with instructions, not as finished texts. The legal notice lists the mandatory details of a specialist contractor, the privacy page describes what the website does technically. We deliberately do not supply legal texts, because they differ for every business.
No. The font and all images are hosted locally, the maps are original drawings, there are no tracking pixels and no Google Fonts. The consent choice and the maintenance checklist are stored in the browser.
Yes. Every heading, every text and every key figure is there without a script, the calculators show a finished starting state, and the mobile menu opens as a jump link. Filters, calculators and forms need JavaScript, but their content is readable without it.
The English version addresses visitors as you throughout, in a plain and factual tone, including form messages and the consent dialog. Your AI adjusts the tone in one pass if your business speaks differently.
Anywhere that serves static files. Astro builds the site into a folder of finished HTML that runs on any web space, without a database or server script. The contact and enquiry forms check the input and send nothing yet, they need a recipient before going live.
Yes. Pay once, yours forever, for your own projects and client projects. You get the complete source code without a watermark and without a subscription.
The photos come from Pexels and may be used commercially, but they show no real business, no real staff and no real projects. Your own photos belong in the team and project sections. IMAGE-CREDITS.md names the photographer and source of every motif.
No. You tell your AI in the project folder what should change, and it finds the place through CLAUDE.md and the seven skills. If you want to work by hand, all texts are in a few data files under src/data.
