Stop writing about yourself on the page that sells
There is a version of every service page that is entirely about the business, and a version that is entirely about the person reading it. The second one converts, and it is usually shorter.
The rewrite is mechanical enough to do on a train. Take each sentence and ask who the subject is. If it is you, try turning it around so the reader is the subject and see whether the sentence survives. Most do, and they get better.
"We use premium materials" becomes "it does not need doing again in three years". Same claim, and the second one is a reason rather than a boast.
This does not mean the business disappears from the site. Credibility has a page and it earns its place there. It just stops interrupting the page whose only job is to help someone decide.
The tell that a page has been written this way is that a stranger can read it once and repeat back what you do. If they have to read it twice, it was written for the people who already know.
