FAQs

Good questions.

Do you handle planning permission?

Yes. We arrange drawings and submit the application, or work with your architect.

How soon can you start?

Usually within 6 to 10 weeks of agreeing the quote. Your quote shows the start date.

How do payments work?

A small deposit, then stage payments as agreed milestones are reached. Never full payment up front.

Are you insured?

Yes, with public liability insurance to £5 million. Certificates are available on request.
