Clearance testing in Crofton: what to know
Crofton is a planned community in Anne Arundel County, west of Annapolis and centred on its golf-course roots. Much of its single-family and townhome stock dates from the 1960s onward, so many homes are now old enough for original roofs, flashing, window seals and below-grade waterproofing to be at or past their service life.
Many Crofton homes have basements or crawl spaces, and the area sits in the humid mid-Atlantic climate where summer relative humidity regularly runs high. Unconditioned crawl spaces and under-ventilated basements are common places for moisture and mold to build up quietly.
Heavily wooded lots and mature tree cover keep shaded roofs, siding and gutters damp for long stretches, and clogged gutters or poor grading near foundations are a frequent route for water into lower levels.
Mold conditions in Crofton
Common mold types in this area: Cladosporium (basement walls and window frames in 1960s–1980s homes); Penicillium/Aspergillus (HVAC condensate and ductwork in ageing systems); Chaetomium (framing and drywall after slow roof or plumbing leaks); Stachybotrys (sill plates and drywall after prolonged basement water intrusion).

Signs you need clearance testing
- Remediation has been completed and containment is still in place
- The written protocol specifies clearance testing as a completion requirement
- A real estate transaction requires documented proof of successful remediation
- An insurance claim requires certified clearance documentation
- The remediator has offered to perform their own clearance (this should be declined)
- A previous clearance test failed and re-clearance is required after additional work
How we handle clearance testing in Crofton
Clearance testing is the final step of any IICRC S520-compliant mold remediation and the critical quality control measure that confirms the work was done correctly. The clearance test must be performed by an independent licensed mold assessor — the company or individual that performed the remediation cannot perform their own clearance test. This independence is mandated by the NYS 2015 Mold Law and is best practice in all markets.
The timing and conditions of clearance testing are specified in the written remediation protocol. Standard protocol requires that containment remains fully in place when samples are collected, that the HEPA-filtered negative air machine has been running for at least 4 hours before sampling, and that an outdoor control sample is collected simultaneously with indoor samples.
