We care about the quality of our work and customer satisfaction
Research Phase
Before writing a single line of code, our research agent studied Expert Plumbing & Gas Services — their current website, social presence, reviews, team, and services. Here's what stood out.
Perfect 5.0 stars from 623 Google reviews — an exceptional volume for a suburban plumber — with team member Ash frequently named by reviewers for quick response, professionalism, and clear communication. An additional 605 first-party reviews appear on the official website.
Founded in 2005 by Leigh O'Hara, who grew up in Gippsland and spent four years at Reece Plumbing before completing his apprenticeship — the business started with Leigh hand-delivering flyers to neighbours' letterboxes in Brunswick and grew into a multi-person team operating from 829 Sydney Road.
Offers a 6-year labour warranty on all work and holds VBA Licence 50967 — positioning that combines compliance certification with unusually strong service guarantees for the trades sector, backed by both plumbing and gas fitting licences.
Design Phase
Every design decision was intentional — informed by the research, not pulled from a template library.
Visual Direction
A 7-page site (the only 7-page build in this batch) with 9 components including a bespoke Wizard for guided service enquiries, testimonial carousel, and floating CTA. Pages cover plumbing services, gas fitting, commercial, renovation plumbing, and a dedicated home services page — built with 1,538 lines of TSX across a high-completeness research base.
Design Rationale
With 623 five-star Google reviews, the design needed to amplify existing trust rather than create it. The Wizard component guides homeowners through describing their plumbing issue step-by-step — converting the 'I have a leak but don't know what to ask for' moment into a structured enquiry. The 7-page structure reflects the genuine breadth of services (drainage, gas, hot water, roof plumbing, commercial) that a single-page layout would flatten.
Build Phase
Site Architecture
// Next.js App Router
Methodology
Spark (research agent) scraped Expert Plumbing & Gas Services's current website, Google reviews, social media, and business listings. Every piece of real data — team names, service pricing, business hours, unique details — was extracted into a structured profile.
Based on the research, a bespoke design direction was created specifically for Expert Plumbing & Gas Services. No templates — the typography, color palette, layout patterns, and visual effects were all chosen to match this business's personality and industry.
Pixel (design agent) built the entire 7-page Next.js application from scratch — 9 custom components, real content from the research phase, App Router with proper routing, and production-grade code.
Sentinel (QA agent) verified the build compiles cleanly, checked for placeholder content, validated all routes render correctly, and confirmed the design is unique (not recycled from another demo).
Additional Notes
Research drew from 11 sources achieving high data completeness — the strongest in this batch. Sources included the official Expert Plumbing website (homepage, about, contact, services, and reviews pages), Google business panel, LinkedIn profile, and directory listings. The founder story, team members, VBA licence number, and 623 Google reviews at 5.0 stars were all verified across multiple sources.
