Residual salt contamination

Residual Salt Contamination

Our Residual Salt Contamination Service detects and removes damaging salt deposits from walls and masonry, treats affected areas to prevent efflorescence and plaster decay, and applies protective barriers to safeguard your property’s long-term health.

When dampness enters a property from either rising damp or penetrating damp, residual salt contamination (mainly chloride and nitrates) can be introduced from the ground and the sea air. As the dampness evaporates, or even if an external defect is rectified, the presence of these salts could still be present within the structure.

These salts are hygroscopic, which means that they have the ability to attract moisture from the atmosphere and will continue to give the appearance of dampness. The higher level of internal moisture, the damper the walls may become. This is the reason that walls can look worse when it is raining and during colder months, as during this time, there is a considerable increase in atmospheric moisture, therefore, more moisture for the salt to attract, resulting in a damper wall.

In fact, certain salts can be evident even if no dampness is present, from chimney stacks for example, where the burning of fuel over the years produces soot which is high in sulphate salts.

In most cases, if residual salt contamination is present, internal re-plastering of the affected areas will be required and it is essential it is carried out to a specific specification. If not, the dampness will return.

RTC are experts in all forms of dampness and will be able to cure your problems once and for all.

Professional from Damp Report to Final Plaster

Delighted with the service. RTC installed a damp proof course and replastering at my house. The damp survey was professional, detailed and very clear on the work to be done with good accompanying explanations of the issues. The office is easy to contact, answering all my calls and returning them promptly if the person I needed to speak to wasn’t immediately available. The technicians who performed the work were professional and worked fast and hard. They explained clearly all the steps and left the house clean every day. I am really please with the final finish and overall result. They were not the cheapest quote or survey I had, but at all steps were the most professional. Highly recommended.

Clear Communication & Impeccable Cleanup

From start to finish the company were very professional. Everything was explained to us. Despite the work being very messy, everything was cleaned up at the end of each day. The two lads who completed the work, Wes and George, were hard working, polite and answered my many questions without any problem. The work was done to a very high standard, and it exceeded my expectations. I would highly recommend RTC, I would not hesitate to use them again.

Transparent Pricing & Top-Notch Workmanship

From initial contact with the office, to the visit from the surveyor, the surveyors report which was very thorough as he actually went under the floors, the price for the work and the quality of the job itself was excellent. The surveyor Sam did an excellent job as was the repairs done by Dan and Karl. After the work was completed, I was contacted by the office to check that I was satisfied with work and the quality of the job, which I was. Professional all the way through with good customer service, made to feel I was important to their business. It’s an old adage but big enough to cope and small enough to care fits the bill. Would use again and would have no reservation about recommending them.

Protected Home, Perfect Finish—Excellent Result

Originally recommended by my surveyor after discovering damp in 5 rooms. All the RTC staff were friendly and did a great job in minimising the dust and mess with protected sheeting and flooring throughout the house. The final result is excellent and a big call out to Steve for helping with moving a very heavy radiator and giving me tips on cauking. Highly recommend if you want a fairly priced job by hghly skilled employees and not subcontractors.
