We provide the following services or analysis and please read our payment terms :

1. PCR DNA Mould analysis
   This technique is considered "State of Art" and is recognised as the most accurate of all mould   analysis. With our close links to USA government approved laboratories we are currently the only UK consultancy offering a complex 23 genus toxic mould DNA analysis. The benefits of this technology is that from limited sampling the genus and species of mould can be accurately determined and from this risk and hazard assessments  of property and occupants health can be made.The cost per sample is £300 plus site investigation etc.


2. Swab analysis for mould
   Use a domestic ear bud wipe it across any mould you want analysed. Place it in a plastic bag and send it by post to us. We will send it to our laboratories for analysis usually received within 10 to 14  days. The cost of this service is £200 per swab and analysis results will only be emailed to you. Post to Building Forensics PO Box 487 Beckenham BR3 9EY with cheque or preferably pay by Pay pal on our site. We require cleared fund prior to analysis.
   
    
3. Leak & condensation inspection
   This survey specifically looks at moisture problems and costs £125 per hour with a minimum of 5 hours charged for. This would usually be a total cost of £500 in or around the London area. Travel costs are charged at the same rate. 


4. Building defect analysis
   This inspection may require sophisticated equipment and our charge of £125 per hour, includes the use of our equipment which includes:
   
   
   • Full range of moisture detection meters
   • Infra red camera
   • Calcium carbide meters and humidity sleeves
   • Minesota blower doors for negative pressure
   • Infra red gas chromatography (Foxboro Miran) and trace gas SF6
   • Particulate analysis GRIMM particle analyser 2.5 to 10 micron
   
    
5. Mould sampling
   Total Spore Counts (Non Viable) as specified by WHO  
   A measured amount of air is drawn through a filter cassette and this is sent to our laboratory for Total  spore counts ( fragments per cubic meter of air) These are compared against the outside levels which should be taken at the same time.
   See typical report Mould analysis
   
   Culturable
   A measured amount of air is drawn over a culture agar dish and airborne live or viable spores are embedded on the agar growth media. Colony forming units are counted over a 3-4 day period and these can be very specific to mould genus (species and possible health hazards and risks.
   
   Site visit minimum of 5 hours at £125 per hour plus following costs:
   
   
   1. Non viable sampling with analysis and report £65 each minimum of two normally required for inside and outside comparison purposes turnaround about 5 days
   2. Culturable SAS or Anderson sampling onto culture dish with a standard MEA agar turnaround about 8 days cost per culture dish used £200 each 
   3. It should be noted that this form of analysis is has extrmly limited application ad is rarely used by Building Forensics.
      
       
6. Air sampling for 400 VOCs and SVOCs
   A small glass tube filled with activated charcoal is placed in a air pump. 42 liters of air are drawn through the glass tube over 3.5 hours. The tube is sealed and sent to our US laboratory where 400 different compounds are analysed by Infra red gas chromatography. The sample can be expected to accommodate up to 2000 square feet of floor space.
   
   Travel time plus minimum 4 hours on site to collect air sampling through purpose made 42 litre per hour pump over 3.5 hours al at £125 per hour.
   Samples sent to US lab by Fed X for next working day delivery £60
   Laboratory analysis per tube is:
   
   
   • Standard rate 12 working days £600 each
   • 72 hours £900 each
   • 48 hours 1200 each

General site inspection and report £95 per hour on site plus travel and report writing.
