Mold Removal & Remediation near San Jose, California

Example Mold Removal and Remediation Report.

Note:  This is a recent mold remediation project report from our main office.  However, it is a good indication of the type of mold remediation problems that arise in the San Jose area.

Upstairs Hall Bathroom

• RH: 57%  Temp: 68 deg F.  CO2 = 808 ppm   CO = 0 ppm
• Moderate amounts of visible mold growth noted on ceiling of bathroom.
• Mold growth also noted around wood window frame.
• No ventilation fan present in the bathroom.
• Heavy stains on wall due to condensation running down the walls.
• Peeling wallpaper noted due to exposure to high relative humidity.
• Paint in bathroom is severely deteriorated and has a high likelihood of being lead based paint.
• Significant amount of dust and dirt has accumulated on the floors, walls and on top of other solid surfaces.  

Recommendations

• Due to the likelihood of lead based paint, all remediation and upgrade work should be conducted according to lead safe practices. 
• Client may wish to conduct lead based paint testing prior to any work being conducted inside the home.
• Recommend installing a Panasonic Whisper Green® ventilation fan in bathroom to assist in evacuating the relative humidity from inside the building.  Whisper Green ventilation fans operate consistently at a low volume (30 cfm) and automatically ramp up to a higher volume (80 cfm) when a motion sensor is activated. An integrated timer will maintain the higher volume for a set period of time and then return the fan to the lower operating level until activated again.
• It is extremely important that any ventilation fan that is installed must be vented directly to the exterior though a dedicated ventilation duct that exits either the wall or through the roof using an appropriately sized collar and vent cap.
• Recommend cleaning all visible mold growth with a mild solution of soap and water.  Stains may be removed by using a stiff bristle brush soaked in water.
• Remaining stains may be covered using a high quality primer/sealer and the surface should be repainted using a high quality gloss paint with antimicrobial properties.
• Recommend removal of all wallpaper to ensure all visible mold growth is found and treated.
• Recommend regular cleaning of the floors, walls and other solid surfaces to minimize the amount of dust accumulation.
