The verdict in three sentences
If your CMS is still maintained and your site already brings in quote requests from Google, a visual redesign at EUR 5,000-10,000 (USD 5,400-10,800) is enough. If the site runs on an outdated PHP version, with no clean admin access and no usable project pages, a new site at EUR 12,000-25,000 (USD 13,000-27,000) costs less over three years. Either way, SEO migration (301 redirects, keeping the URLs that rank) matters far more than design.
Redesign or rebuild: what you are actually buying
A construction company with 50 to 200 employees sells on three fronts: public tenders, private clients (developers, property managers, industrial owners) and recruitment. The website has to serve all three. Yet most sites in the sector were built for a 15-person business, with a photo gallery and a contact form.
| Criterion | Visual redesign | New site |
|---|---|---|
| 2026 budget | EUR 5,000 - 10,000 | EUR 12,000 - 25,000 |
| Timeline | 6 - 8 weeks | 10 - 14 weeks |
| CMS | Kept (recent WordPress) | New (WordPress, headless or Next.js) |
| Page architecture | Adjusted | Rethought by trade and audience |
| Project pages | Restyled | Filterable project database (trade, city, value) |
| Careers section | Simple page | Structured openings, online applications |
| SEO risk | Low | Medium, controlled with a redirect plan |
A redesign keeps the engine and changes the body. A rebuild changes both, which makes sense when the engine is leaking.
The 5 criteria that settle the decision
We use this grid in workshops with company owners. Every red light points toward a new site.
| Criterion | Green light (redesign) | Red light (new site) |
|---|---|---|
| CMS and hosting | WordPress 6.x, PHP 8.2+, full access | Version over 3 years old, PHP 7, vendor unreachable |
| Technical debt | Fewer than 15 plugins, standard theme | Hard-coded theme edits, 30+ plugins, broken pages |
| Existing SEO | 300+ organic visits/month, rankings on core trade terms | Under 50 visits/month, no useful rankings |
| Content | 20+ documented projects, HD photos | 5 photos from 2016, no project sheets |
| Security | HTTPS, backups, updates applied | Site already hacked or Google Search Console alert |
Rule of thumb: three or more red lights, go for a new site. Two or fewer, the redesign pays off. Security is a special case: an already compromised site justifies a rebuild even if everything else is fine, because partial clean-ups often leave backdoors.
What a 2026 construction website must include
Public buyers and developers check your site before shortlisting you. They look for proof:
- Project sheets: client, trade package, indicative value, duration, before/after photos, certifications used.
- Trade pages: structural work, renovation, site utilities, asbestos removal, each with local references.
- HSE page: accident frequency rate, ISO 9001/45001 certifications, carbon policy.
- Careers: 30 to 40% of construction site traffic comes from candidates in 2026, given the shortage of site managers and project managers.
- Mobile first: project managers and buyers browse from job sites or on the road.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Marc, owner of a 120-employee structural works company in Marseille (EUR 28M revenue), was weighing two quotes: a redesign at EUR 8,500 or a new site at EUR 19,000. Audit: WordPress 4.9, PHP 7.0, 34 plugins including 9 abandoned ones, 40 organic visits per month. Four red lights out of five.
Redesign cost over three years: EUR 8,500 + forced technical upgrade in year 2 (estimated EUR 6,000) + corrective maintenance EUR 2,400/year, totaling EUR 21,700. New site cost: EUR 19,000 + maintenance EUR 1,200/year, totaling EUR 22,600. A gap of just EUR 900, for a brand-new site with a project database and careers module. After 6 months, the site generates 11 qualified tender invitations per month versus 2 before. One contract won with EUR 400,000 revenue at an 8% gross margin pays for the project.
FAQ
How much does a construction company website cost in 2026?
Budget EUR 5,000 to 10,000 for a visual redesign and EUR 12,000 to 25,000 for a new site with a project database and careers section. The range depends on the number of trade pages and integrations (ATS, CRM).
Will I lose my search rankings by switching sites?
Not if the 301 redirect plan covers 100% of indexed URLs. A temporary 10 to 20% traffic dip for 4 to 8 weeks is normal, then the curve climbs back if the structure is better.
What timeline should I plan for?
6 to 8 weeks for a redesign, 10 to 14 weeks for a new site. The bottleneck is almost always collecting project photos and data on the client side.
Do I need a custom CMS?
Rarely. A clean WordPress or a headless CMS covers 95% of construction companies. Custom builds only make sense with a client extranet or a subcontractor portal.
Who writes the project sheets?
The agency provides an 8-field template and writes from your data. Plan 30 minutes of interview per project and EUR 150 to 250 per written sheet.
