The short answer

Sometimes — depends on the theme. Custom themes built well: yes, we’ll work with them. Page-builder themes (Astra + Elementor, Divi, Avada): no — we rebuild on FSE. Marketplace themes (ThemeForest, TemplateMonster): usually no — the architecture isn’t worth preserving.

№ 01The longer answer

If your theme is custom-built and follows modern WordPress practices (block-based, theme.json design tokens, properly enqueued assets), we’ll work with it. The theme is a foundation we extend with new patterns, page templates, and design refresh.

If your theme is page-builder dependent (Elementor + Astra, Divi, Avada, Bridge, etc.), we recommend a full rebuild on FSE. The page-builder architecture caps performance ceilings, drives plugin sprawl, and constrains the design. Keeping it means keeping the problems.

If your theme is a ThemeForest or similar marketplace theme, we typically recommend a rebuild. Marketplace themes ship with bundled plugins, opinionated structures, and abandonment risk. Building custom is cleaner than trying to refactor a marketplace theme.

The exception that proves the rule: GeneratePress, Kadence, or Astra (free, non-Pro versions) used minimally as a starter theme can be acceptable. Most uses we see in the wild are with the page-builder add-ons, which puts them in the page-builder bucket.

№ 02What if I love my current design and just want it improved?

We can preserve visual design through a rebuild — the design language stays, the architecture changes. The end result looks like your site, performs like a custom build.

№ 03Can you build on top of my existing custom theme?

Yes, if the theme is well-written and modern. We’ll audit first. If the theme is older than 2-3 years or uses outdated patterns (parent/child theme without FSE), a rebuild is often cleaner.

№ 04How long does a rebuild take?

Same as a new build: 14 days for Standard tier (25-40 pages). The content stays; the theme architecture changes.
