The verdict in three sentences
In 2026, a construction company website in Nantes costs between 3,500 and 9,000 EUR depending on the depth of the project gallery, the showcasing of certifications (energy labels, quality marks) and the recruitment area. A construction site does not sell a product but proof: the prospect judges on completed projects, labels and reviews. Done well, it becomes both a quote machine and a recruitment tool, two vital stakes in a labour-tight sector.
What a credible construction website costs in 2026

What generates quotes and attracts candidates
The project gallery is the heart of the site: before/after photos, location, type of work. Each project is proof. Energy and quality certifications are not decorative — they gate access to public subsidies and reassure on compliance. The recruitment area with openings and an application form answers the labour shortage: in construction, attracting a good team leader is gold. Finally, local SEO on geolocated queries turns the site into a steady source of quote requests.
Mini case study
Bâti-Ouest, a 14-employee renovation firm in Nantes, invests 6,200 EUR in the "Established firm" package with trade galleries, certification badges and a guided quote form. Before, the firm depended 90% on word of mouth and received 2 requests a month from an old site. Six months later, local SEO on "energy renovation Nantes" brings 8 qualified quote requests a month, of which 3 signed at an average basket of 18,000 EUR. The recruitment area also enabled hiring two roofers without an agency, saving about 6,000 EUR in recruitment fees.

Should certifications be visible?
Absolutely: they gate access to public subsidies for your clients and reassure on compliance. Display logos and certification numbers on the homepage and trade pages.

Yes: a "join us" area with openings, company culture and an application form captures candidates directly. In a tight sector, this saves thousands in agency fees.

With good local SEO, a well-built construction site often generates 6 to 10 qualified requests a month after 6 months. A guided quote form improves request quality.
What SEO budget should we plan?
Budget 300 to 800 EUR per month for local support on geolocated queries. It is often the best-ROI line item for a construction firm.
