Documentation / edition 2026.08
Data & methodology
ChimneySweepCompare is an independent, searchable index of 921 public certification records organized into 524 local indexes. It restructures source records for comparison; it is not a review site, certifying body, or endorsement service.
Source repository
The current edition was compiled from CSIA public professional directory in August 2026. The index preserves source fields where available and adds geographic normalization so records can be browsed by state and city.
ZIP searches use GeoNames postal-code place data under CC BY 4.0 to identify the ZIP's place and nearby indexed markets. Distances are approximate, and a nearby-market result does not prove that a provider serves the ZIP; confirm service territory directly.
Important limitation
Listings are compiled from CSIA public professional directory and other identified public sources. ChimneySweepCompare is an independent directory, not a regulator or certifying body, and a listing is not an endorsement. Verify current status and scope before hiring.
Corrections and verification
Source registries change. Consumers should confirm current status with the issuing program before hiring. Professionals can submit a documented correction; source-derived credential facts remain labeled separately from provider-supplied contact updates.
