Heating & Hot Water
Radiator Installation & Repairs in Watford & Hertfordshire
New radiators and towel rails fitted neatly, and old ones that leak or will not heat put right.

We replace tired radiators, move them to suit a new layout, upsize them where a room needs more heat and fit heated towel rails in bathrooms. New thermostatic valves give you control room by room.
We also fix radiator problems: cold spots, leaking valves, radiators that will not heat and noisy systems. Often the cause is sludge or air in the system, and we will tell you if a flush would help.

What affects the price
Swapping a radiator in the same position is a quick job. Moving radiators or changing pipework takes longer. We agree the price before we start.
“Selvin and his team were absolutely amazing. We had them install our new radiators which was not a small job! Selvin was very knowledgeable and caring, he helped us and informed us on the best options for our home.”

Questions
Radiator Installation & Repairs: common questions
Why is my radiator cold at the bottom?
Usually because sludge has settled in the bottom of the radiator. A flush of the radiator or the whole system clears it.
Can you move a radiator?
Yes. We reroute the pipework to the new position, ideally keeping it hidden under the floor or neatly along the skirting.
