Building your dream home is a significant investment. Choosing the right builder is just as important as the bricks and mortar.
This guide covers the 15 questions to ask your builder before work begins. Whether you’re building a custom home, an extension, or starting a new construction project, these are the essential questions to ask.
Why Asking the Right Questions Matters
Every builder is different.
The key is to ask the right questions that uncover how they work, communicate, and deliver.
These questions will help you:
- Understand their experience
- Avoid red flags
- Choose the right fit for your project
Let’s dive into the top 15.
1. Are You Licensed and Insured?
Ensure your builder carries public liability insurance and is registered with a licensing board or trade body like the Federation of Master Builders.
This protects you legally and financially.
2. Can You Show Me Similar Projects?
Ask to see a portfolio of recent, similar projects.
A reputable builder will proudly showcase their work.
3. Can I Speak with Past Clients?
Ask your prospective builder for client references.
Speaking to previous customers offers real insight into reliability, quality, and professionalism.
4. What Experience Do You Have in My Type of Project?
Whether you’re building a custom home or remodelling a kitchen, it’s important to know that the contractor has relevant experience.
The builder should be able to explain their process and show examples.
5. Who Will Manage the Build?
Find out if the company has a dedicated project manager, or if the builder oversees the job.
Good oversight is crucial for quality and deadlines.
6. Will You Use Subcontractors?
Many builders rely on subcontractors.
Ask how they vet them and ensure consistent work across all trades.
7. What Is the Timeline for the Project?
This helps set realistic expectations and identifies whether they juggle too many jobs.
Timelines should include key stages of your build process.
8. How Do You Handle Permits and Inspections?
A good builder will manage planning permissions, building contracts, and work with inspectors.
Ask how they coordinate this process.
9. What Is Included in the Quote?
Be clear on what’s included: labour, materials, VAT, warranties, and timelines.
Ask about extra costs and what might change the quote.
10. What Warranty Do You Offer?
Reliable builders offer clear warranty coverage on both labour and materials.
Ask what guarantees they provide, and how claims are handled.
11. What Will the Payment Schedule Look Like?
Agree on a structured payment schedule.
Avoid large upfront payments. Make sure the payment is linked to project milestones.
12. How Do You Communicate During the Project?
Weekly check-ins? Daily calls? Emails?
It’s essential to know how your builder will keep you informed.
13. Are You a Member of a Trade Association?
A reputable builder is often part of a recognised organisation like the Federation of Master Builders.
This gives extra confidence in their commitment to best practice.
14. What Happens If Something Goes Wrong?
From extra costs to unforeseen issues, get clarity on how they manage change orders and delays.
The answer to this critical question will reveal their professionalism.
15. Why Should I Choose You Over Other Builders?
This question gives the builder a chance to explain their strengths.
You’ll quickly learn how well they align with your vision and values.
