New Build & Renovations
Jericos specialises in first fix, 1st fix and 2nd fix plumbing and heating for new build and extension projects across Marlow and Buckinghamshire. With over 20 years of local experience, our qualified engineers deliver precise, reliable work that keeps every new build and extension on schedule and running smoothly.
We work seamlessly with main contractors, developers, and homeowners to ensure clear communication, minimal disruption, and complete satisfaction for everyone involved. From single-room extensions to full new build homes and large-scale Grand Design-style projects, we handle it all with professionalism and attention to detail.
First Fix
First fix (also known as 1st fix) forms the essential hidden infrastructure for every new build and extension. At Jericos, we complete all carcassing work before plastering, ensuring pipework, drainage, and services are perfectly routed and protected.
Our first fix / 1st fix services for new build and extension projects include:
- Hot and cold water pipework installation using high-quality press-fit systems
- Secondary hot water returns for larger properties to ensure instant hot water at all taps
- Full above-ground waste and soil pipework (all drainage runs above ground)
- Gas supply pipework and connections
- Central heating pipe runs and manifold preparation
- Underfloor heating pipe loops laid and protected prior to screeding — including complex multi-level installations and within wooden suspended floors
- All systems are pressure tested at the end of first fix
We use advanced press systems for both copper (M-Press, Aquagas, Geberit and similar) and plastic (Buteline). This modern jointing method eliminates the need for flames onsite — removing hot works tickets and associated risk. Buteline also avoids the reliability issues common with push-fit fittings. The result is faster, cleaner, and more dependable installations that main contractors love.
Whether it’s a modest extension, a complete new build, or anything in between in Marlow, our first fix and 1st fix work is completed efficiently and to the highest standards.
2nd Fix
Once plastering and tiling are complete, Jericos returns for 2nd fix to bring your new build and extension systems to life with visible, fully functioning installations.
Our 2nd fix services include:
- Installation and final connection of boilers, radiators, and smart heating controls
- Fitting of bathrooms, kitchens, and en-suites with all sanitaryware, taps, and showers
- Underfloor heating manifold installation and commissioning (expertise across multiple floor levels and suspended timber floors)
- Final system flushing, balancing, testing, and handover
- Full above-ground waste connections to appliances
All 2nd fix work is carried out with the same attention to detail and collaborative approach. We keep main contractors informed at every stage, ensuring tidy sites and happy project teams. Our press-fit expertise continues through 2nd fix, delivering robust, leak-free joints throughout.
