How this site is researched, reviewed and corrected.
To let a reader either complete an installation safely themselves or brief and evaluate a professional installer properly.
Guidance draws on manufacturer mounting and fixing specifications, published electrical code principles, industry installation practice, and observation of publicly advertised installer pricing. Price figures are indicative ranges, dated, and labelled as such.
Where a topic touches electrical code or law — in-wall power routing, security camera audio recording — we state the general rule, note that requirements vary by jurisdiction, and say plainly when something is licensed work. We do not soften those points to make a job sound more approachable than it is.
We are not owned by, and do not act for, any manufacturer, retailer or installation company. We do not accept payment for recommending products or contractors, and we do not publish sponsored rankings. Where we describe typical pricing it comes from publicly advertised rates.
Pages carry an update date and are reviewed when standards, code or market pricing change. Report an error and we will check it; substantive corrections are made on the page and the date updated.
Nothing here is legal, electrical or engineering advice. Where our guidance conflicts with your local code, an inspector, or a manufacturer's instructions for your specific product, those take precedence.
