The unanswered call is the largest leak in a window replacement shop
In a trade where the buyer is calling three companies in one sitting, whoever picks up first usually gets the measure.
Pull the call logs and count missed and abandoned calls by hour. In most shops the pattern is obvious and painful: calls go unanswered exactly when the crews and the owner are on a job.
Fix the coverage before touching the website. An answering service briefed on your trade, a shared line that rings a second person, or a scheduler who books measures directly all beat another round of headline testing.
Return every missed call with a text within minutes. A short message naming your company and offering two appointment windows recovers a meaningful share of the people who have already dialled someone else.
Track it as a metric with an owner. Answer rate belongs on the same report as cost per lead, because the two numbers multiply.
