It seems to be working alright but …

… it is making strange noises … it is barely tepid … it looks a bit rusty … If you are having these doubts about your radiator, then take a good look at it. If it is looking forlorn and sorry for itself then it needs some loving care, usually in the form of maintenance. A close inspection should reveal all the radiator’s woes, here are some warning signs to look out for:

  • tiny cracks,
  • pinhole leaks,
  • rusty patches,
  • dubious valves,
  • damp piping
  • wet spots on the floor

Elderly radiators

The above conditions can be found in older radiators. These hefty old-style iron or metal radiators were built a long time ago, but they were built to last. Indeed, your classic old-fashioned radiator usually keeps going for decades and generally gives good service. However, age will tell sooner or later, so keep a look-out for the above signs of wear and tear and contact No1PHD at the least indication of anything suspicious. Older radiators tend to get painted periodically, to freshen them up or to match the walls, and a coat of paint can hide any tell-tale signs of cracking or leakage, making fault detection harder; best call in the experts, the No1PHD Southampton radiator repair team.

Couldn’t have asked for a faster resolution to our drainage conundrum. Nothing was too much for these guys who were brilliant throughout.

It might be a good idea to carry out a general inspection at the start of winter when you turn on the heating. The solid iron or metal radiator sections are already lined up in each room, standing to attention, hoping to pass muster. Inspections are visual and touchy-feely. Any visual sign of dripping, wetness or damp spots on the floor under the radiator is a clear indication of a problem. Also, rust on the joints between sections or on the piping is a warning. Leaks can be minute, almost invisible, so also a hands-on inspection is necessary. Radiators should feel perfectly dry to the touch so where you feel any dampness, that is where the problem is. After this first inspection, do a sound-check: turn the heating on. If the gurgles and hisses seem right and the radiator warms up nicely, all should be fine. But, if you still have doubts, contact No1PHD, our radiator repair experts know exactly what to look for to detect any potential leakage problems.

Radiator repair or replacement?

Repairing older radiators is generally a valid option when they develop problems. The super-solid build of old-style radiators makes them good candidates for repair operations and they can continue to serve faithfully for years. The secret is maintenance. Have a chat with our radiator repair people, they can advise about radiator upkeep and care, and the best solution for your particular heating system. They can also inform about the advisability of radiator replacement; if the radiator in question has various issues then a radiator replacement could be the best answer.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
