Replumbing house involves replacing outdated pipes with modern systems to improve water flow and safety. In Dublin, prices start around €9,850 for smaller Apartments and can exceed €14,850+ for complex or older properties.
💡 Some plumbers may advertise lower prices for “replumbing house” work, but these often exclude full system replacement, modern PEX or copper materials, or the hidden labour costs that come up once walls and floors are opened. At Dublin Plumber 24 hrs, our pricing reflects a complete, guaranteed service with no surprises — covering everything from safe installation to long-term reliability.
Why Replumbing House Matters
Pipes don’t last forever. In many Dublin homes, especially those built a few decades ago, the plumbing is now showing its age. Old steel or lead pipes can rust, leak, or even affect your water quality. Even copper from the 1970s–80s may have reached the end of its lifespan.
Choosing to carry out a full replumbing house project isn’t just about fixing leaks. It’s about improving water pressure, making sure your heating system runs efficiently, and protecting your home from future damage. A new plumbing system also adds value if you plan to sell or renovate later.
At Dublin Plumber 24 hrs, we’ve been helping homeowners replace outdated systems for over 23 years. We know when a patch-up will do, and when it’s time for a full upgrade.
Replumbing House Cost in Dublin
The first question most people ask is “How much does it cost?” A full replumbing house project in Dublin usually falls between €9,850 and €14,850+, depending on the property.
Here are some of the main factors that shape the final cost:
Size of the home – apartments need less pipework than detached houses.
Number of bathrooms – more connections mean more labour and materials.
Pipe materials – copper costs more than PEX but is longer-lasting.
Access – easy access under floors keeps costs down; tricky older homes take longer.
For example, a small apartment may be on the lower end, while a large detached house with multiple bathrooms could reach the higher range.

Cost to Replumbing an Old House
Older Dublin houses often need more than just new pipes. Timber floors may be fragile, walls may be solid brick, and old heating systems usually connect in unusual ways. All of this adds extra time and labour to the project.
When replumbing an old house, we sometimes discover hidden leaks, asbestos pipe insulation, or corroded fittings that were never upgraded. These surprises can push the cost closer to the higher end of the €9,850–€14,850+ range.
If you’re planning a full renovation, it’s worth combining the job with a bathroom renovation or Gas boiler replacement. Doing everything together saves on labour and avoids opening up the same floors twice.
Materials – PEX vs Copper
One of the biggest decisions in any replumbing house project is the type of pipework. In Dublin, the two main options are:
PEX (cross-linked polyethylene):
Flexible, quicker to install, and more affordable. Ideal for modern builds or where access is tight.Copper:
Durable, heat-resistant, and trusted for decades. Costs more but has a longer lifespan.
Many homeowners now choose PEX for cost savings, especially in larger houses. Others prefer copper for its reputation and resale value. At Dublin Plumber 24 hrs, we advise based on your budget, property type, and long-term plans.
How Long Does It Take to Replumb a House?
Time is just as important as cost when planning a replumbing house project. For most Dublin homes, a standard 3-bed semi takes 5 to 7 working days. Apartments are often quicker, while large detached homes with multiple bathrooms may stretch to two weeks.
We usually work room by room, so you don’t lose water everywhere at once. In many cases, you can still live at home while the work is carried out, though some families prefer to stay elsewhere for comfort during a full system replacement.
Average Cost to Replumb a House – Quick Reference
You might see adverts or quotes suggesting a full replumb can start from around €9,850. While that can be true for very small homes or limited work, most Dublin properties fall into higher ranges once all pipework, bathrooms, and heating connections are included.
Here’s a realistic guide to costs based on property type:
Small apartment / 1–2 bed home: €9,850 – €11,150
Standard 3-bed semi: €11,750 – €14,850
Large or older homes with complex layouts: €14,850+
These figures cover full system replacement, with variations depending on access, materials (PEX vs copper), and the number of bathrooms.
