See What Our Customers Say About Our Repair Services
Underfloor heating faults are not always obvious. We take the time to inspect the system, identify the likely cause and explain what can be repaired.
Our approach is based on clear communication, careful testing and practical recommendations.
From the first quote to the final commissioning, the team installed our underfloor heating without any fuss. Every room heats evenly now, there are no cold spots, and it's freed up all our wall space. Genuinely first-class work.
We had underfloor heating fitted throughout the ground floor and couldn't be happier. The installers were tidy, on time, and explained how the zone controls and thermostats worked before they left. Highly recommend them.
Really pleased with our new underfloor heating. Good advice on the layout and a clean, professional fit under the new floor. Only reason it's not five stars is the job took a day longer than planned, but the end result has been excellent.
Outstanding from start to finish. They assessed the floor build-up properly, recommended the right underfloor heating system for our home, and the installation was seamless. The whole house is warm underfoot now and it runs beautifully.
Brilliant service and great value. Our underfloor heating was installed with minimal disruption and the engineers were polite and knowledgeable throughout. Lovely warm floors and a cosy home — exactly what we hoped for.
Get Your Underfloor Heating Checked in 3 Simple Steps
We make the repair process straightforward, from learning about the problem and inspecting the system to completing the agreed work and testing the results.
1. Tell Us What Is Happening
Let us know which rooms or heating zones are affected, when the problem started and whether the system is electric or water-based.
Photos of the thermostat, manifold, controls or error messages can help us understand the system before visiting.
2. We Inspect and Diagnose the Fault
We inspect the relevant components and carry out suitable tests to narrow down the source of the problem.
The fault may involve a thermostat, sensor, electrical connection, heating cable, manifold, pump, actuator, valve or system setting.
3. We Explain and Complete the Repair
Once the likely cause has been identified, we explain the available repair options and any parts or additional work required.
After the repair, we test the affected area and check that the controls are operating correctly.
Professional Underfloor Heating Repairs for Irish Properties
Underfloor heating systems contain several components that must work together. When one part develops a problem, the room may stop heating, warm unevenly or become difficult to control.
Electric systems can experience problems involving thermostats, floor sensors, electrical connections or heating cables. Wet systems can develop faults involving manifolds, pumps, actuators, valves, controls, air in the pipework or incorrect flow settings.
The visible problem does not always reveal the actual cause. A cold floor, for example, could be caused by a faulty thermostat, failed actuator, circulation problem or control setting rather than damaged pipes or cables beneath the floor.
We inspect the system carefully before recommending work. Where possible, we aim to locate and repair the specific fault without replacing the entire underfloor heating system.`
Common Underfloor Heating Problems We Investigate
Some faults affect the entire system, while others only affect one room or part of the floor. The symptoms below can have several possible causes, which is why proper testing is important.
The Floor Is Not Heating
A system that does not heat at all may have a power, thermostat, control, pump, valve or heat-source problem.
One Room or Zone Is Cold
If other areas are working, the fault may involve an individual thermostat, actuator, wiring connection, flow setting or heating circuit.
The Floor Heats Unevenly
Uneven heat may be linked to poor flow, trapped air, an incorrect system layout, damaged cables or issues with the floor construction.
The System Is Slow to Heat
Slow performance can be affected by insulation, floor thickness, water temperature, flow rates, controls or the selected heating schedule.
The Thermostat Is Not Working
A blank screen, incorrect temperature reading or unresponsive thermostat may indicate a power, wiring, sensor or control fault.
Heating Costs Have Increased
Incorrect schedules, unnecessarily high temperatures, poor zoning or a system fault can cause underfloor heating to use more energy than expected.
Can Your Underfloor Heating Be Repaired?
A complete system replacement is not always necessary.
Many problems are caused by accessible parts such as thermostats, sensors, actuators, pumps, valves or system controls. Replacing or adjusting the affected component may restore the heating without disturbing the floor.
A more involved repair may be needed if the problem is located in a heating cable, pipe loop or another component beneath the finished floor. The repair options will depend on the exact fault, system type, flooring and access available.
Replacement may be considered when the system is badly damaged, poorly designed, no longer compatible with the property or affected by several recurring faults.
We assess the condition of the system and explain whether a repair, partial upgrade or replacement is the most practical option.

Brands We Work With
Why Choose Us
Careful Fault-Finding Before Repair Work Begins
Underfloor heating problems can have similar symptoms but very different causes. We inspect the system before recommending parts or disruptive work.
Electric and Wet System Knowledge
We investigate faults affecting both electric heating mats and cables and water-based pipe systems.
Complete System Checks
We consider the controls, heat source and individual heating zones instead of focusing only on the visible symptom.
Clear Repair Advice
We explain what has been found, which repair options are available and whether further investigation is required.
Targeted Repairs
Where possible, we focus on the affected component or area instead of recommending unnecessary system replacement.
Maintenance and Upgrade Support
We can also advise on servicing, controls, system balancing and improvements that may help prevent recurring problems.
Local service coverage
We provide underfloor heating repairs across Dublin and throughout the surrounding Leinster counties.
Do Not Ignore a Faulty Underfloor Heating System
A small control or flow problem can eventually affect the comfort and performance of a larger part of the system.
If one room is cold, the thermostat is behaving unexpectedly or the system is making unusual noises, arranging an inspection can help identify the issue before further problems develop.
For wet systems, water around the manifold or repeated pressure loss should be investigated promptly. For electric systems, stop using the affected circuit if it repeatedly trips the electrical supply or shows signs of an electrical fault.
When contacting us, provide as much information as possible, including the system type, affected rooms, thermostat model and any error messages. Photographs can also help us prepare for the inspection.
Not Sure What Is Wrong With Your Underfloor Heating?
Tell us what the system is doing, which rooms are affected and whether it is electric or water-based.
Our team will explain the next step and arrange suitable fault-finding where required.
Tell Us About the Problem

faqs
Can underfloor heating be repaired without removing the floor?
Yes, many faults involve accessible parts such as thermostats, sensors, pumps, actuators, valves or controls. If the fault is beneath the finished floor, targeted access may be required once its location has been identified.
Why is one underfloor heating zone not working?
A single cold zone may be caused by a faulty thermostat, actuator, valve, electrical connection, incorrect flow setting or trapped air. The affected zone needs to be tested to identify the cause.
Can a damaged electric underfloor heating cable be repaired?
In many cases, a localised cable fault can be repaired after the damaged area has been accurately located. Whether this is practical depends on the cable, fault position, floor finish and access available.
Why is my wet underfloor heating not getting warm?
Possible causes include trapped air, low flow, a circulation pump problem, closed valves, failed actuators, thermostat faults or incorrect water temperatures. The manifold, controls and heat source should be checked as part of the diagnosis.
How much does an underfloor heating repair cost?
The cost depends on the system type, fault, replacement parts, time required and whether access beneath the flooring is necessary. We first assess the problem and explain the likely repair requirements.
