Castro’s – Plumbing done properly, from first fix to flawless finish.

First Fix Plumbing – The Foundation

First fix is all about the behind-the-scenes work that gets your plumbing system ready. It’s installed before walls, floors, and finishes go in — setting the stage for a reliable, efficient system.

Includes:

  • Hot and cold water pipework
  • Soil and waste pipe installation
  • Boiler and cylinder positioning
  • Underfloor heating preparation
  • Water main connections

We make sure everything is perfectly positioned for a smooth and stress-free second fix later.

Second Fix Plumbing – The Final Touches

Once the space is ready, we return to complete the job — installing the visible parts that bring your plumbing system to life.

Includes:

  • Taps, sinks, showers, baths, toilets
  • Radiators and towel rails
  • Connecting boilers and appliances
  • Final pressure testing and checks
  • A clean, professional finish


We pay attention to the details so your fixtures don’t just work — they look great too.
