This is a reading resource rather than a business, and it does not run a contact desk.
Corrections
Published guidance is reviewed and amended over time. Accuracy is the only thing a reference site has to offer, and a page out of date on a code requirement is worse than no page at all.
Finding a Contractor
For finding a contractor, the reliable approach has not changed. Local licensing records, trade association listings, and quotes from more than one established firm with references that can be checked.
Not a Contractor
Nothing here is an offer of service. It does not perform that work, quote for it, or arrange it on a reader's behalf.
