Odor removal is a specialized process by which odor molecules are either masked, sorbed, paired, destroyed through disinfecting or sanitizing, or sealed as in encapsulation. At Systematic Cleaning and Restoration we are I ICRC certified in odor control. What this means to you as a consumer is that we’ve been trained on the latest best management practices for odor mitigation.

The nose is the only odor detection instrument.

There is an entire physiology of odor detection where the pure sensation of smell is paired with thoughts and memories impressed gins and suggestions so for each odor is unique. This is what makes odor removal so complex. In addition odor particles are very small in size in some cases as small as the molecular level this allows them to penetrate surfaces to a very large degree. This in turn makes it more difficult to remove certain types of odors from certain types of materials. Things that will exacerbate this are absorptive or poor services such as carpet or ceiling tiles, heavy residue and sufficient time for this odor penetration to occur, rapid thermal expansion of their (think of a fire with smoke) and then of course once that rapid thermal expansion has occurred the cooling and thus closing of those pores trapping the odor inside. Odors can come about through many issues. From areas that remain wet, grow mold and then put out VOC’s (affectionately known in the industry as mold farts), issues with dead organisms, fire, etc.

There are some basic principles that are taught for total odor removal. These are removal of the primary source. This would include things like getting rid of heavily contaminated items getting rid of char getting ready debris all things that are heavily contaminated with odor. Cleaning all surfaces exposed to the odor. If you do not remove the odor the odor will persist. Re-creation of the conditions of penetration with the proper odor counteractants. This would include increasing the temperature of an area that was exposed to fire and smoke and releasing an odor counteractant to penetrate into the areas previously inundated. And then of course you have sealing or coating using a nonporous compound to actually encapsulate these odors within a surface.

The options that are given for total odor removal are mainly dependent on the type and source of odor that are present. In all cases though it starts with source removal as often as possible. It doesn’t matter how many masking agents or deodorants air cleaners etc. that are employed if the dead deer in the front yard is not removed. So we always look for the source of the odor. In many cases determining how the odor came about(source, type), the length of time that it was present, and the materials that it is binding to will give us enough information to properly remove the odor. In some cases we will use several different methods to remove odors properly and completely. In fact it is a rare occurrence that odor removal employs one type of chemical or process that cures the issue. This is why it is so important to get a professional odor removal company. At Systematic we have the knowledge, experience, training and equipment to get your odor removal project done properly and with lasting results.

Kitchen Exhaust Cleaning

Kitchen exhaust cleaning is a necessary part of ongoing maintenance to prevent fires from occurring within the hotel. In most cases this cleaning is provided on a quarterly basis although in some cases where wood or charcoal is used as a heat source the NFPA requirement is monthly. The National Fire Protection Association is a body that studies fires and puts forth best management practices prevent fires and save lives.


It is typically the standard that is followed by those authorities having jurisdiction when it comes to fire prevention in not only hotels but in almost all aspects of industry.

Kitchen exhaust cleaning in hotels encompasses the removal of grease, soot, creosote, and other fire hazards from within the ducts that carry exhaust from the stoves, broilers, fryers and grills used in commercial kitchens. These systems encompass filters, a hood to hold these filters, a plenum above the hood in larger systems, duct work, and a fan.

All these areas need to be cleaned down to bare metal to comply with the NFPA requirements for proper kitchen exhaust cleaning. In New York City the Fire Department of New York provides a special certificate of fitness for those that clean kitchen exhaust systems. This certificate of fitness shows that the person cleaning the system has the proper knowledge, as well as insurance provide the job in a correct manner.

The FDNY has special requirements due to the risks of grease fires in commercial kitchen exhaust systems including hotel kitchen exhaust systems and the special firefighting procedures it takes to combat these fires. For example with systems that are three stories or under in height they require that the vertical runs be cleaned every visit. For systems that are three stories or over the requirement becomes twice per year. In addition they have several areas that are mandatory and we as commercial kitchen cleaning companies must report defects directly to the fire department essentially “telling” on our customers.

Some of these mandatory requirements are things like access panels being present and labeled every 10 feet as well as every change in direction, the reporting of any areas that cannot be properly cleaned, the prohibition of any electrical wires within the hoods ducts or fan area, the reporting of any visible grease leaks as well as a few others. Systematic has no issues with these mandatory requirements because they promote the safety and integrity of the system. But based on years of experience in the business it is rare to find accessible areas in all systems and in many cases trying to get a business owner to correct that situation is sometimes a strenuous process.

In addition while cleaning hotel kitchen exhaust systems is important that the system is left not only clean but fully operational as well as aesthetically pleasing. So in addition to the interior cleaning we also provide a clean and polish the exterior to add to the beauty of the kitchen. It is unfortunate that many companies concentrate on this alone and do not actually clean the system to required codes. This is typically the case where a company under bits the job and due to time constraints cannot efficiently or effectively clean the areas that are critical. It is important that you as a manager or owner check the interior of your system to ensure that the proper job is being done.

With Systematic Cleaning we provide not only a good job but one that is verified with pictures from before and after. In addition we are happy to open up access panels for you to visually inspect the interior areas of your system. This way you can remain confident that your system is being cleaned properly and that your system remains operationally safe to minimize the risk of fire.
