The verdict in three sentences
In construction, a dated or slow site drives clients away before they even see your projects. A targeted redesign (5,000 to 14,000 EUR) foregrounds your work, structures trade pages and eases the quote request, with a typical +30% lead gain. Starting from scratch is only warranted when content and site architecture must be rebuilt entirely.
Redesign or new site: decide fast
The question isn't technical but strategic: do you keep the existing structure and content? A redesign reuses assets (copy, references, existing SEO); a new site starts blank, longer and costlier.
| Approach | When to choose it | 2026 budget | Timeline |
|---|---|---|---|
| Light redesign | Good content, dated design | 5,000-8,000 EUR | 5-6 wks |
| Full redesign | Structure + design to rework | 8,000-11,000 EUR | 6-8 wks |
| Premium redesign | Animations, deep SEO, 15+ pages | 11,000-14,000 EUR | 7-8 wks |
| New site (from scratch) | No reusable assets | 12,000 EUR and up | 8-10 wks |
For most construction SMEs whose local SEO already exists, a redesign preserves earned rankings while modernizing the image.
The redesign budget line by line
A serious quote breaks down every value block. Here is the 2026 split of a redesign at around 9,000 EUR.
| Line item | Detail | Budget share |
|---|---|---|
| UX/UI + mockups | Responsive design, brand | 20-25% |
| Build + CMS | Editable site, back-office | 25-30% |
| Project gallery | Filters, before/after, photos | 15-20% |
| Trade pages + local SEO | One page per trade, tags | 15-20% |
| Quote form | Multi-step, notifications | 8-12% |
| QA + go-live | Tests, training, delivery | 8-10% |
The project gallery and trade pages are the two levers that weigh most on conversion: a client buys the proof before the pitch.

Mini case study
Marc, owner of a structural works SME in Toronto (14 staff), gets 18 quote requests/month via a 7-year-old, non-responsive site. He invests 9,500 EUR in a redesign with a 40-project gallery, 5 trade pages and a quote form, plus 200 EUR/month of maintenance.
Within 4 months, requests rise to 24/month (+33%). With a 20% close rate and a 45,000 EUR average project, the 6 extra requests generate roughly 54,000 EUR of potential monthly revenue. The redesign pays for itself with the first signed project.
FAQ
How much does a construction site redesign cost in 2026? Expect 5,000 to 14,000 EUR depending on page count, gallery and animation level. Maintenance adds 120-300 EUR/month.
Redesign or new site, which pays off more? The redesign, if your local SEO and content exist: it preserves rankings and costs less than a from-scratch rebuild.
How long does the project take? 5 to 8 weeks depending on scope, including mockups, build, gallery and QA. Project photography is often what stretches the timeline.
Is the project gallery essential? Yes: in construction, visual proof converts. A filterable gallery with before/after markedly increases quote requests.
What is the maintenance retainer for? Security, backups and small changes. Expect 120-300 EUR/month depending on site size and desired responsiveness.
