Methodology and data sources
Everything on Bywatts comes from a named source. This page says where each dataset comes from, how often it refreshes, and exactly what our labels mean.

What our labels mean
Verified
The listing's owner proved they control the company's own web domain by signing in with an email at that domain. Verification is free, it is earned, and it cannot be bought. A paid plan never grants it.
Owner-provided
Information a verified owner supplied about their own listing, such as a description, phone number, or service areas. We do not independently check it. Owner edits never overwrite the underlying source record, so the original data stays intact.
Sponsored and Featured
A paid placement on a directory page. It is advertising. It is not an endorsement, it is not a quality ranking, and it says nothing about whether the listing is verified.
What we do not do
- We do not run analytics, advertising trackers, or tracking pixels.
- We do not sell visitor data.
- We do not invent listings, reviews, or ratings.
- We do not contact installers who have not claimed their listing.
Corrections
If something here is wrong, tell us and we will fix it. Owners can claim their listing to correct it directly, or anyone can use support.
