Leaking radiator fix services


Our company has been providing radiator repair services in London for more than 10 years. The duration of the company’s presence in the city’s radiator services market testifies to the demand for such work, and the constant increase in orders received for processing allows us to speak of the high quality of their execution. A quick and high-quality fix of a radiator system as a whole or its individual components in the form of pipes, supply lines, taps or meters is available to all customers, after sending an application for processing to our customer service managers.

The use of separate apartment radiator systems allows for the utilization of lightweight aluminium radiator blocks with flexible connections. Is your radiator leaking water? Need help with a leaking radiator valve nut? Perhaps you are experiencing problems with the central heating radiator leaking from bottom? The heating system fix is carried out by the employees of our company in the shortest possible time and can include a complete replacement of the radiator with the connection of meters, as well as the replacement of individual leaking radiator pipe or leaking radiator valve. The features of the modern apartment heating system allow the use of a polymer pipeline, which greatly facilitates the performance of work. Radiator fix of any complexity will be carried out by our employees, taking into account all requirements and standards for owners of residential and residential properties, as well as for customers represented by municipal services and public authorities.

When fixing heating systems, it is necessary to take into account the potential for pressure drops in the main pipelines, as well as the likelihood of water hammer. Such conditions impose restrictions on who can carry out the work on fixing heating systems in office and home premises. Radiator installation and then connection to a city centralized heating system can be quite risky when PVC pipes are used to strap the radiator unit. It is also worth abandoning the use of thin-walled aluminium and steel radiator units, due to their vulnerability to overpressure and water hammer. Similar problems often arise in the urban heating system. Often, radiator problems are encountered at the very beginning of the heating season, when hot water is supplied to the mains under increased pressure.


Fix of heating systems, regardless of whether we are talking about a separate radiator or complex work with the piping of the radiator unit, requires the plumber to have significant experience in central heating radiator leak repairs. It is important to remember that theoretical knowledge gained in isolation from practice will not allow you to qualitatively perform the docking of the components of the heating system, and the problem of a leaking radiator nut may not be the worst option. A serious accident with breaks in the radiator block supply can lead to significant property damage and harm the health of people who are near the radiator at the time of the accident.

The repair of faulty radiator units is carried out by our specialists on the basis of work contracts. This means that all potential customer risks associated with the loss of property as a result of accidents in heating networks will be compensated. Do not forget that the contract provides for long-term warranty obligations to preserve the performance of the heating system and allows you to eliminate a house radiator leak in the shortest possible time and completely free of charge.

Only the professionalism of the performers of the radiator fix work and excellent knowledge of their design and engineering part allow achieving reliable operation of all radiator system components. For the best results, you need to know the methods for calculating the diameter of the radiator piping, the number of sections of the installed radiator and the basic principles of their placement in residential premises, so that the result of the work is able to meet the needs of customers in a sufficiently high and comfortable temperature for heating the premises. Do not forget that after installing the system, you must make sure that there are no internal defects. Only a qualified specialist has the necessary means for ensuring the proper operation of your radiator units at home.



The main malfunctions of the new radiator of the heating system in apartment, commercial and administrative buildings tend to appear at the time of the start of the heating season. At the same time, the very implementation of construction and installation work in this area, as a rule, falls on the first months of summer, when there is still a long way to check of the quality of the installation of radiator units and adjacent structures. Such a drawback is often exploited by dubious organizations who offer customers to replace the radiator unit privately without concluding contracts. Do not forget that fix of radiator units by people who do not have professional equipment or sufficient skills leaves you vulnerable to the occurrence of radiator problems at the most inopportune moment.


The circuits and piping of repaired radiator units must be checked for tightness at the joints. To determine the actual quality of radiator fix services, it is necessary to pressurize the system, which cannot be carried out without specialized equipment and the participation of people who have the skills to apply it. In order for the radiator system to be qualitatively assembled, so it fulfils its functional purposes reliably for a long time to come, the participation of experienced engineering personnel in the work should be considered as a prerequisite. It is necessary to present such a requirement to the contractors before the approval of the conditions for the work and their approximate content.
