A site usually tells you when it is done. It does not work on a phone: text too small, a menu that will not open, a form nobody can fill in. It stopped bringing calls, or it never did. The hours and the services on it are out of date and nobody knows how to change them. The person who built it is gone, or still owns it, or wants a monthly fee to touch it. The photos are from a camera three phones ago.
A redesign is not starting over. Most sites have something worth keeping: the domain, a page that still gets found, copy that says the right thing, photos of real jobs. We keep those and replace the rest.
The price is the same as a new site: Standard from $2,450 for five pages (up to eight), Full from $3,400 with a page for each service. The pricing page has what changes it.
