Stay calm · we're on the way
A few things that genuinely help — and a few that make it worse. Read these while we head to you.
Try a back door, ground-floor window, neighbour with a spare key, or your landlord/agent. Saves you a call-out fee if you find a way in.
Kicking, drilling, or wedging cards turns a £85 lockout into a £300+ replacement. Step back and let us pick it open cleanly.
Driving licence, council tax bill or tenancy agreement showing the address. We always check before opening — for everyone's safety.
Rogue traders quote £49 then bill £450 once they're done. We give you a fixed price over the phone before we arrive — same rate day or night.
Wait somewhere well-lit (a neighbour, local cafe, your car). Drop us a pin via WhatsApp so we know exactly where you are.
Call 101 for non-emergency police first — you'll need a crime reference number for insurance. Then call us. We can board up tonight and replace glass tomorrow.
