This URL redirects to https://www.sarrosenvironmental.com/.

Lighthouse follows the redirect, so the numbers below describe the destination page, not this one. The move is confirmed, so measurement has already followed it — no config change needed, and the history came along.

Moved from https://www.sarrosenvironmental.com/.

History from the previous URL is included below, with the move on Sep 7, 2026. A step-change around that point is likely the change of address rather than a regression.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).
