Do you visit before quoting?
Yes. Smaller repairs can sometimes be estimated from photos, but extensions and renovations need a site survey.
Can you work from architect drawings?
Yes. Send drawings, calculations and planning documents with your enquiry if you already have them.
Do you manage subcontractors?
Yes. We can coordinate trusted electricians, plumbers, decorators and specialist trades as part of the project.
