Water extraction at your Glen Head, NY property removes standing and surface water — but extraction equipment cannot remove moisture that has been absorbed into structural materials. The moment extraction is complete, the drying phase begins: structural framing, subfloor assemblies, wall cavities, and concrete have all absorbed water that only evaporative drying can remove. PureDry Solutions takes post-extraction baseline readings immediately after extraction is complete and before drying equipment is placed — measuring what the extraction left behind in the structural materials at every affected location. These post-extraction readings are the opening entries in the psychrometric drying log: the documented starting point that proves both the thoroughness of extraction (the remaining moisture is in structural materials, not free-standing water that should have been extracted) and the initial drying load that the equipment must address.

Post-extraction moisture readings serve two distinct documentation purposes. First, they prove extraction was performed to the appropriate standard: if floor surface readings immediately after extraction still show free-standing water moisture levels, extraction was not complete and additional passes are required. If surface readings show moisture consistent with material absorption rather than surface water, extraction removed the extractable water and the remaining moisture is in the structural material — which is the expected and appropriate post-extraction state.
Second, post-extraction readings establish the drying load that justifies the drying scope. A structural framing reading of 40% MC post-extraction requires significantly more drying equipment-days to reach IICRC dry standard than a reading of 25% MC. The post-extraction readings document the actual starting moisture load — the scientific basis for the equipment type, quantity, and duration specified in the drying scope. Without post-extraction readings, the drying scope cannot be justified by data; it can only be asserted by the restoration company. PureDry Solutions provides the data.
Category 1 clean water extraction begins immediately without containment — clean water aerosol from the extraction equipment carries no contamination risk. Category 2 and Category 3 extraction proceeds inside established containment with confirmed negative air pressure before extraction equipment is activated — contaminated water aerosol generated by the extraction process is contained within the work zone. The contamination classification and extraction method are documented in the project record before the post-extraction baseline readings are taken.
Before the post-extraction baseline readings are entered into the psychrometric log as the starting point, PureDry Solutions performs an extraction completeness check: surface moisture readings at floor level across the entire affected area confirm that no pooled or surface water remains. Locations with surface-water-level readings receive additional extraction passes before the baseline is established. The extraction completeness check ensures that the psychrometric log baseline reflects structural absorption moisture, not unextracted standing water — a meaningful distinction for both drying scope planning and claim documentation.
Equipment type, quantity, and placement are determined from the post-extraction baseline readings — not from a standard layout applied to square footage alone. High moisture content zones receive more targeted air mover coverage. Zones with concrete or dense materials receive dehumidifier sizing appropriate to the slower evaporation rate of those materials. The baseline reading map is the equipment deployment plan input: readings drive placement, not habit. This baseline-driven deployment approach is documented in the psychrometric log's equipment setup entry, connecting the instrument readings to the equipment decisions they produced.
