Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

Its website also mentions financing, warranty, free estimate, established, insured and licensed, but not in a sentence we can quote cleanly.

• It is also reviewed on Yelp. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.
• It posts on Facebook. A page that stopped posting years ago tells you something a listing will not.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

• —The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
• —Google publishes no street address for this company, so we cannot say which town it is based in. Lanham is the area its listing was returned for, not an address we hold.
• —We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
• —We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
