Questions, answered
Do you charge for quotes?
No. We visit, talk through what you want and give you a detailed written quote free of charge, with no obligation.
How much does an extension cost?
It depends on size, spec and groundworks, so we never quote blind. After a site visit you'll get a fixed written price broken down by stage, so you can see exactly what you're paying for.
Do you handle planning permission and building regs?
Yes. We work with architects and building control throughout, and can manage drawings, planning applications and sign-off so you're not left chasing paperwork.
Are you insured?
Yes — we carry full public liability insurance and all work is completed to current building regulations. Certificates are available on request.
How long will my project take?
A kitchen or bathroom is typically one to three weeks; a single-storey extension around eight to twelve weeks. You'll get a written schedule before we start and regular updates throughout.
Do you guarantee your work?
Yes. All our workmanship is guaranteed, and manufacturer warranties on materials are passed to you on completion.
