Boulder has a recorded history of water arriving all at once. The City of Boulder says that from Sept. 11 to 15, 2013, it and other Front Range communities had significant rainfall that led to flooding, loss of life and widespread damage. NOAA's Physical Sciences Laboratory lists 9.08 inches on 12 September 2013 as the highest daily precipitation total in the Boulder record, and 17.59 inches as the record monthly total for that September. For a basement flood cleanup, that history is a reminder that water damage is not always a small leak, and that drying can take time when a lot of water has come in. Before you hire, ask who will do the extraction, drying and any mould work, and ask for the scope of work in writing. Ask what moisture readings will be taken and how you will be told when the structure is dry. Check what licences or certifications the company holds and whether they carry insurance. Keep photos and records for your insurer, and compare quotes by what each one includes rather than by the headline figure alone.
