Back Porch Seam Field Guide publishes guides and takes no enquiries, which this page exists to say plainly.
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.
Corrections
Guides are rewritten rather than left to rot. Accuracy is the only thing a reference site has to offer, and a page out of date on a code requirement is worse than no page at all.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. Verify licensing and insurance directly with the issuing body, get at least three written quotes, and ask each firm for recent local work you can look at.
