Construction and repair of underfloor heating

Underfloor Heating Construction and Repair

Underfloor heating is one of the most comfortable ways to warm a home or business. Heat rises evenly from the floor, helping eliminate cold spots and reducing drafts compared with traditional radiators. Whether you are planning a new build, renovating a single room, or dealing with an existing system that is not performing as it should, we provide end to end underfloor heating construction and reliable repairs.

We work with both water based and electric systems, selecting the right solution for your property, floor finish, and daily usage. From design and installation to fault finding and preventative care, our goal is simple, consistent warmth you can trust.

Design and Installation for New Builds and Renovations

A great underfloor heating system starts with the right design. We assess heat loss, room layout, insulation levels, and floor build up to specify pipe spacing or heating mat coverage, manifold location, and control zones. This approach helps avoid common issues like slow warm up times, uneven temperatures, and excessive running costs.

Water based underfloor heating

Hydronic systems circulate warm water through pipes under the floor. They are ideal for larger areas and whole property projects, especially when paired with modern heat sources. We install insulation, clip rails or fixing systems, pipework, manifolds, pumps where required, and zone controls. If the project includes other heating services, we coordinate the system so everything works efficiently together.

Electric underfloor heating

Electric systems use heating mats or loose cable and are often chosen for bathrooms, kitchens, and smaller rooms. We plan safe routing, sensor placement, and thermostat location, then install the heating element and carry out electrical testing. Electric underfloor heating can be a smart option where floor height is limited or the room is used on a schedule.

For both types, we pay close attention to floor finishes such as tile, engineered wood, vinyl, or carpet. We confirm suitable temperatures, adhesives, and underlay choices so you get comfort without damaging the finish.

Underfloor Heating Repairs and Fault Finding

If your underfloor heating is not warming properly, it is rarely a one size fits all fix. We begin with a structured diagnostic process to pinpoint the cause, then recommend the most practical repair, from a minor adjustment to component replacement.

• Cold spots or uneven heat often points to air in the system, incorrect balancing, or insulation problems.
• System not heating at all can be caused by thermostat faults, wiring issues, pump failure, or a tripped safety device.
• Low pressure in water systems may indicate a leak, a filling loop issue, or expansion vessel problems.
• High running costs can result from poor control settings, incorrect flow temperatures, or missing insulation.

On water based systems we check manifold flow meters, actuators, pump operation, and mixing valve settings. We also verify that each zone opens and closes correctly and that flow temperatures match the floor type. When repair work extends beyond the floor heating loop, we can align it with broader hvac repair services to restore full comfort quickly.

For electric systems we test the thermostat, floor sensor, insulation resistance, and continuity of the heating cable. If a cable fault is suspected, we use specialist tools to locate the break as accurately as possible, reducing disruption to the floor. Where feasible, we carry out a targeted repair and re test to confirm safe operation.

Maintenance, Optimisation, and Upgrades

Regular care keeps underfloor heating efficient and extends component life. Maintenance is especially important for water based systems, where air, debris, or incorrect balancing can slowly reduce performance.

• Bleeding and balancing zones for consistent heat distribution
• Checking actuators and thermostats for accurate control
• Inspecting pumps, valves, and manifold components
• Assessing insulation and floor build up where issues persist
• Reviewing schedules and set points to reduce energy waste

We also provide upgrades such as modern programmable thermostats, smart zoning, and improved controls that allow room by room comfort. If you are updating your wider system, we can integrate underfloor heating with heating installation work so your heat source and controls operate as one coordinated setup.

What to Expect When You Book

We keep the process clear from the first visit to final commissioning. After an initial assessment, we explain the options in plain language, confirm what will be required for access and floor build up, and provide a detailed plan of work. On installation projects we pressure test water circuits before the floor is closed and commission the system only after all checks are complete. On repair jobs we confirm the fault, outline the repair route, and test performance before we leave.

Whether you need a brand new underfloor heating system or a fast, careful repair, we focus on safe workmanship, reliable comfort, and results that last.
