Introduce of MIST mold sterilization process and cost

 

For Mold sterilization for your residence, office and public spaces,

We Alone use “MIST”  (Mold Improvement Special Technology ) method developed by Sera inc. ( http://www.sera.jp/) who has been working for Mold sterilization throughout the world over 20 years.

 

We are really proud of MIST method and its performances, achievements and trust from historical temples, shrines, and especially important cultural properties.

 

 

So, Today, we introduce our MIST mold sterilization process and cost  for you!

 

MIST mold sterilization process

Our full process are as follows:


On-site Pre tests

Step.1 Visual check

 

To check the mold contamination level and contaminated area, and also measured indoor humidity and temperature.

 


 

Step.2 Moisture Measurement

 

To check the leaks and/or to access the potential risk of mold growth  by using some types of  non-disruptive moisture meters.

 


 

Step.3 Mold tests

 

For obtaining the risk of health effects and allergy, and also estimate how much space and which rooms you should  sterilize,  We select 2 types of mold tests: Air sampling and Surface sampling.

 

Air samplings are selected to estimate contamination level of mold in the area.

 

Air samplingtests  need  almost for 30 minutes or more to settle down indoor air before sampling and to set the sampling plates and capture the mold spores.

 

After closing the film of sampling sheets, we bring back them to our lab for culturing under 25-27 ℃ for 120 hours.

 

 

After cultivation, visible colonies are counted and the results are checked using the table .

 

 

Exposure level Number of Mold spores Class Observation Judgement
level 1 0 Clean A
level 2 < 5 ± Moderate contamination B
level 3 < 14 High Contamination C
level 4 ≧ 14 ++ Serious contamination F

Referenced by MHLW notice.

 

 

Surface samplings are selected to assess presence and identification of mold groups.

 

 

After stamping or swabbing, we bring back them to our lab for culturing under 25-27 ℃ for 120 hours, and then Visible mold colonies observations and Direct Microscopic  examination are done in our lab.

 

 

 

 

 

 

Step.4: Mold test report and proposal


We make the report for discussing with you to decide the sterilization area and treatment. (If you need a full report to hand in somebody or official record, please ask us before mold tests.)

 

 

Step.5 Making Quotation


After discussion, we give the final quotation for mold sterilization and set the date to do.

Or, if you have already found some visible mold and/or have some limited budget or deadline of remediation , we would skip mold test and  make a quotation as soon as possible.

 

 

 

Sterilization process

We normally visit and work on a team.


Step.1 Cleaning all surface for effective penetration of MIST special solution into the surfaces and walls.


 

 

Step.2  Killing Mold

 

The most important thing to prevent regrowth is Killing mold hyphal

We do it by brushing and wiping using MIST-1 agent (sodium hypochlorite, tenside..etc)

Penetration and Drying time should be needed after working to ensure the effects.

 

 


 

Step.3  Sterilization


Killing mold spores floating in the space and attached on the surfaces using MIST-SP agent(ethanol, etc.)  to eliminate the risk of next mold growth.

Penetration and Drying time should be needed after working to ensure the effects.

 

 

 

Step.4 Antimicrobial coating

 

Spraying Ag+ solution for antimicrobial coating to prevent attachment of mold spores etc.. and to eliminate odor, too.

 

 

Step.5 After checks, Report and Certificate


Some air sampling and surface sampling to check the effect of MIST works.

 

 

We can make  the mold sterilization work report and certification at your request.

 

If you need periodical checks or periodical sterilization for your office, school and residence, we are happy to do it with  discount price.

 

 

 

Mold tests and MIST mold sterilization cost

 

We introduce the basic cost of mold tests and MIST mold sterilzation and some cases for your information.

 

Mold tests


- Base Inspection fee  : 15,000 Yen * including sampling, cultivation , making report

 

- Air Sampling : 3,000 Yen/ sheet

 

- Surface sampling : 13,000 Yen/ sample *including identification of mold group

 

- Water content measurement  : Depend on the measurement area and the necessary of report (document)

 

- Transportation fee : actual cost  for over 100 Km for round trip from our Toda , Saitama HQ

 

Plus tax 8%

 

 

Case 1 : Mold test for  one room (6 tatami mats = 11 m2)
We recommended  5 air sampling (4 corners and the center of the room) , one or two surface sampling – one should be taken  from the surface of susupected area  at least.

 

3,000 Yen × 5 = 15,000 Yen

13,000 Yen × 1=13,000 Yen( when you try one surface sampling)

15,000 Yen for inspection fee

————————————–

Total : 43,000 Yen —-> 46,440 Yen (tax included)

 

 

Case 2. Mold test for the Office  (35m2) with visible mold on the wall


We recommended  8 air sampling, two surface sampling – one shold be taken  from the surface with visible mold and another will be taken from the other surface without any visible mold to estimate the damage from spreading by mold spores and water content measurment for the report to the landlord to eliminate mold problems with the landlord.

 

3,000 Yen × 8=24,000Yen

13,000 Yen ×2 = 26,000 Yen

30,000 Yen for water content mearsurement

15,000 Yen for inspection fee

———————————————-

Total : 95,000 Yen —-> 102,600 Yen (with Tax)

 

 

MIST Mold sterlization fee
