Specialist Services – Odour Removal

When it comes to odour removal, Juvenaire has extensive experience and can provide solutions to tackle even the most challenging cases. No matter how strong or weak the odour, Juvenaire can remove it successfully and economically.

How is odour detected?

Odour is interpreted by sensation, experience, knowledge and suggestion. There are two types of odours, “real odour” a pure sensation of smell transmitted to the olfactory lobe by the olfactory nerve and “psychological odour or heightened awareness odour” that people think they smell based on experience, suggestion and past experience. The latter is the most difficult odour to address for the restoration technician.

How is odour transmitted?

An increase in humidity amplifies odour as does the increase in temperature and evaporation. The penetration of odours into soft furnishings is greatly increased by extreme temperatures.

Unfortunately, there is no one solution that can be applied to all odours and relying solely on one form of deodorisation technique for all odour control will most likely result in ineffective odour removal. Understanding what is causing the odour allows Juvenaire to put the steps in place to eliminate the odour completely.

Physical procedures for Odour Removal:

  • Eliminate the source – The first universal step in odour control is to eliminate the source by removing the debris or the contaminants.

  • Clean the contaminated area – Walls, ceilings, hard floor surfaces, concrete, carpeting, upholstery fabrics, drapery and other surfaces may have absorbed the odours that require extensive cleaning for the final removal of the odour. These may not be in direct contact with the odour source however, they must be considered for complete odour removal.

  • Recreate the conditions of contamination – it may be necessary to increase the temperature to recreate similar conditions that created the odour. It enables the pores of the materials to expand and allows for improved penetration of spray, fog or ozone gas and enables the odours to be effectively removed.

  • Sealing the source – It may be necessary to seal the source that was exposed to the contaminant. Sealing surfaces exposed to the concentration of malodour may be required for permanent odour removal and will prevent its evaporation into the atmosphere.

  • The right process – Understanding the type of odour can assist in the right applications for its removal. For instance, some odours such as protein odours or decomposing body odours are much more difficult to remove than the odours caused by tobacco smoke or a small kitchen fire.

Three effective methods for Odour Control

  • Masking – To disguise an odour with a more pleasant odour or covering an odour with a fragrance that is stronger. Almost all deodorising agents contain a masking agent. Masking agents are often used to provide temporary concealment of the odour until permanent odour control techniques can be employed. More often than not, masking agents are the most effective means of counteracting psychological odour.

  • Pairing – A chemical that combines with the molecular structure of the malodour molecule or substance, by importing some of its own chemical properties. This transforms the odour-cell’s chemistry into a new, non-odorous compound. There are many water soluble deodorisers available as well as electronic deodorising such as ozone gas oxidisers.

  • Modification – By using a chemical that changes the molecular structure of the odour cell and eliminating its ability to produce the odour. There are three (3) types: 1. Attacking – counteracting; 2. killing – bacterial based odours (disinfecting agents) and 3. Enzymes – digesting.
