What is Your Experience with Projects Like Mine?

One of the first questions to ask your builder before you shake hands and commit, it’s crucial to gauge their experience. You want someone who has successfully completed projects similar to yours. So, don’t hesitate to ask about their past work.

Find out how many home extensions they’ve tackled and the types they specialise in. You might say something like, “I’m really interested in a loft conversion—have you done many of those?” A seasoned builder will be able to share their expertise with confidence and might even have a few stories that bring their experience to life.

Can You Provide References and Examples of Past Work?

A reputable builder should be more than happy to showcase their previous work and provide references. Think of it like checking the reviews before booking a holiday. Reach out to those past clients and ask them about their experiences.

You could ask questions like:

•“How was your experience with the builder?”

•“Did they keep you updated throughout the process?”

These conversations will give you valuable insights into what you can expect.



How Do You Handle Changes and Unforeseen Issues?

Home extensions can be unpredictable, so adaptability is crucial. One of the most important questions to ask your builder is how they manage changes and unforeseen challenges. Ask, “What’s your approach if I want to make adjustments during the project?” A builder with a clear process for handling changes can offer peace of mind and flexibility.

What is Your Timeline for Completion?

Understanding the timeline is essential for your planning. Ask your builder about their estimated start and finish dates. It’s perfectly reasonable to say, “I want to understand the timeline so I can prepare my family and our routines.”

You should also ask about factors that might cause delays. Whether it’s weather issues or sourcing unique or less common materials, knowing what can impact your timeline will help you manage your expectations.

What is Included in the Quotation?

Ah, the quotation. This is where things can get a bit tricky, but it’s essential to have clarity. Ask your builder for a detailed breakdown of your house extension costs.

Get specific about what’s included in the price—labour, materials, permits, and any potential extra fees. You might want to ask, “If the project runs over budget, how will that be handled?” A transparent builder will be upfront about these details.

Who Will Be On-Site During Construction?

Knowing who will be on-site brings reassurance, so it’s worth asking, “Who will be present during construction?” Knowing your project manager and main point of contact means you’ll know who to approach with questions or concerns throughout the build.

You could say something like, “Who will be my main point of contact during the build?” This way, you’ll know who to turn to with questions or concerns throughout the process.

How Do You Ensure Safety and Compliance with Regulations?

Safety is a top priority on any construction site. You’ll want to know about the builder’s safety protocols. Ask questions like, “How do you ensure that all work complies with H&S and local building regulations?” A responsible builder should have a solid plan for keeping the site safe and adhering to all necessary guidelines.

What Warranties or Guarantees Do You Offer?

It’s always reassuring to know that your investment is protected. Inquire about any warranties or guarantees the builder offers.

For instance, you might ask, “What kind of warranty do you provide on your work?” Understanding what is covered and for how long will give you confidence in your decision.

Are You Insured?

Insurance may not be the most exciting topic, but it’s essential. Don’t hesitate to ask your builder, “Are you insured?” A reputable builder should willingly share proof of liability and workers’ compensation insurance, so you’re protected against unforeseen issues on-site.

A simple way to find out is by asking, “Could you share your insurance details with me?” A responsible builder will be transparent about their coverage, allowing you to focus on your exciting project without worry.
