How booking and the site survey work
- Send the details Fill in the form and give us your floor plan or site photos; if the files are large, send them over WhatsApp instead.
- Assessed online Our engineers review the details within one working day and reply on WhatsApp or by phone with an outline plan and budget.
- Engineer visits the site Once the direction is agreed, an engineer surveys the site at the time we arranged.
We send a WhatsApp confirmation two hours before setting off. Please reply to it so the visit is confirmed.
