Why Builders Lose Jobs to Missed Calls
Building projects are high-value, long-lead enquiries. Homeowners research for weeks, then call 2-3 builders on the same evening. The one that captures the enquiry professionally wins the site visit.
You're on site with machinery — phones ring in your van
You're operating a digger, cutting timber, or laying foundations. The phone rings. By the time you wash up and check, it's gone to voicemail. That was a £25,000 extension enquiry. Your competitor answered.
Emergency structural calls can't wait until tea break
A customer calls about a crack in their wall, a sagging ceiling, or a collapsed garage. They need immediate reassurance. If you don't answer in 3 rings, they call the next builder on Google. These are often insurance-paid jobs worth £5,000+.
Extension enquiries need detail — voicemails don't deliver
'Hi, I need a quote for an extension' tells you nothing. How big? What type? Budget? Timeline? Planning permission status? Katie captures all of this — property age, project scope, budget range, architect involvement — so you arrive at the site meeting fully prepared.
Weekend calls from serious buyers go to voicemail
Homeowners research builders on Saturday and Sunday evenings. They call 2-3 firms. The one that answers — or at least captures the enquiry professionally — gets the site visit. By Monday, the serious buyers have already chosen.
