Construction and trade businesses in Johannesburg lose the most website enquiries at the same two points: when a potential customer cannot find a recent project portfolio in under 15 seconds, and when the mobile page takes longer than 3 seconds to load because a developer used uncompressed site photography. The agencies on this list have built construction and trade websites that generate and convert inquiry volume-not WordPress installs with stock images of hard hats that were never updated after handover.

Buyer's Checklist
These are the questions and checks that separate construction & trades specialists from general web agencies who will list your sector on their homepage after you sign.
Optimised project portfolio with before/after galleries and project-specific detail pages-not a single lightbox page titled 'Our Work'
Mobile-first page speed above 80 on Lighthouse-construction photography is inherently high-resolution; ask how the agency handles image compression and lazy loading
Quote request form that captures project type, rough budget range, and postcoded location-routes directly to the sales pipeline, not a generic email inbox
Trust signal architecture: Checkatrade, TrustMark, FMB membership, and manufacturer accreditations displayed correctly with verification links
Google My Business schema and local SEO setup for '{trade} in Johannesburg' searches-the highest volume search pattern for most trade businesses in Johannesburg
Platforms & Tech Stack
Custom WordPress
The overwhelmingly dominant choice for Johannesburg construction and trade businesses. Project portfolio via custom post types with location taxonomy; Gravity Forms for complex quote request forms.
Next.js (larger contractors)
Justified for national contractors or property developers with large project portfolios and high organic search traffic where Core Web Vitals performance is a direct differentiator.
Buildxact / Procore (project management embed)
Some larger Johannesburg contractors embed project management or client portal links. These are separate SaaS tools, not website platforms, but should be accounted for in the web agency brief.
Squarespace / Wix (small sole traders only)
Acceptable for a sole trader with a limited budget who needs an online presence without ongoing maintenance. Not recommended once a business is pursuing contract work above £100,000-the SEO ceiling and portfolio customisation limits will restrict lead generation.

Questions & Answers
Pre-brief questions that construction & trades businesses in Johannesburg ask before commissioning a web project.
A sole trader or small contractor website with service pages, project gallery, and contact form costs £1,200–£4,000 in Johannesburg. An established contractor site with 20+ project case studies, quote request form, and accreditation display costs £4,000–£12,000. Property developer marketing sites run £8,000–£25,000. National contractor sites with tender document hubs and multi-region portfolios cost £18,000–£60,000.
Tender-stage buyers in Johannesburg look for ISO 9001 and ISO 14001 certification display, a documented health and safety policy page, named project case studies with contract value and client references, Constructionline or CHAS accreditation badges, and a verifiable company registration number. Websites without these elements are not competitive on public sector or large private contractor tender shortlists.
Not necessarily a construction specialist, but you do need an agency that understands project portfolio optimisation and high-resolution image handling for construction photography. A generic web developer who delivers a site with uncompressed project images will create a page that loads in 8–12 seconds on mobile-effectively invisible in Google's local pack for '{trade} Johannesburg' searches.
