Contact
This is a reading resource rather than a business, and it does not run a contact desk.
Guides, Not Services
Nothing here is an offer of service. Hiring somebody is a separate matter the reader arranges directly with a local firm.
Finding a Contractor
The usual checks are still the ones that matter. Speak to previous customers directly rather than reading testimonials, and confirm insurance independently of what the firm says.
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 Accuracy is the only thing a reference site has to offer, and a page out of date on a code requirement is worse than no page at all.
