During a Lead Paint Inspection, representative readings are taken of the painted surfaces of the house using an x-ray fluoroscope, commonly referred to as an XRF.
The objective of this non-destructive test method is to determine what the lead content (mg/cm2) is of the house's building components. Federal guidelines define lead paint as containing 1.0 mg/cm2 or greater of lead, although local standards may be tighter. In Maryland paint containing 0.7 mg/cm2 or greater is considered lead based paint. |

It not the objective of Lead Based Paint Testing to determine if the Lead Based Paint present is a hazard or not, which is beyond the scope of the test and may be determined through a later Risk Assessment. This will be dependend on the condition of the paint which will naturally change over time.
The client will be provided with a detailed test report indicating each of the readings which were taken and whether or not they are considered lead based paint. You can click here to view a Sample Test Report. Test reports are typically available by email within 3 business days.

Radon tests can be either “long-term”, lasting typically over 90 days, or “short-term” lasting less than 30 days. Testing strategies usually involve performing an initial short-term test to get a snap shot view of the concentrations, and based on these results, draw some inferences regarding the year-round concentrations and the need for corrective action or additional follow-up.
Short-term screening tests done as part of a pre-purchase home inspection are usually performed over 2 to 7 days under controlled "closed building conditions". You can click here to view the Closed Building Conditions Notice for the occupants residing in a house when a test is underway. |

These conditions must be started at least 12 hours prior to beginning the test or it must be extended beyond the 48 hour minimum. USEPA Radon Testing protocols for passive test devices specify that duplicate passive test devices need to be placed in the lowest potentially livable area of the house. The results of these tests are averaged and compared with the USEPA "Action Level" of 4.0 pCi/l. Results at or exceeding the Action Level warrant follow up, and in the case of a real estate transaction this action is usually the instalation of a remediation system.
Test results are typically available on the day the test is concluded. You can click here to view a Sample Test Report.
