Short answer
Pick a company that gives a detailed written quote, shows finished projects you can visit, carries insurance and offers a written guarantee. Ask these questions of any builder, including us.
Which questions should I ask any builder?
These separate reliable firms from risky ones.
- Can I see or speak to recent clients?
- Is the quote itemised, with what's excluded?
- Who manages the site day to day?
- What insurance and guarantee do you provide?
- How are variations priced and approved?
- What's the payment schedule? Is it tied to stages?
What are the red flags?
Large upfront deposits, cash-only pricing, no written contract, and vague one-line quotes.
Frequently asked questions
How many quotes should I get?
Three detailed quotes is a good benchmark. Compare scope, not just the total.
