Planning a house extension is exciting, but it can also feel overwhelming. The builder you choose will have a huge impact on how smooth the process is, how well the work is finished, and whether the project stays on budget and on time. As experienced house extension builders in Woking, we have seen how asking the right questions early can save homeowners a lot of stress later on.
At CBC Builders, we believe an informed customer is a confident one. Below are the key questions we recommend asking before you commit to any builder, and why they matter.
1. Do you specialise in house extensions?
Not all builders are the same. Some mainly work on new builds, others focus on repairs or small renovations. House extensions come with their own challenges, from tying new structures into existing ones to working around families still living in the property.
When speaking to potential home extension builders in Woking, ask about their specific experience with extensions similar to yours. A builder who regularly delivers extensions will be better prepared for the practical and planning issues that can arise.
2. What services are included from start to finish?
A clear understanding of what is included in the service helps avoid confusion later. Some builders only handle the construction phase, while others offer a full project management service.
At CBC Builders, we offer a complete service from start to finish and work with our customers throughout the project. When comparing builders, ask who will manage the build, coordinate trades, and keep you informed at each stage. This makes a big difference to how stress free the experience is.
3. Will you help with planning and building regulations?
House extensions often require planning permission and must meet building regulations. It is important to know whether your builder can guide you through this process or work alongside your architect or structural engineer.
Ask how familiar they are with local requirements in Woking and whether they have experience liaising with building control. Reliable house extension builders in Woking should be comfortable working within these frameworks and advising you when needed.
4. What is the expected timeline and how are delays handled?
Timeframes matter, especially if you are living in the property while the work is being done. Ask for a realistic project schedule and how deadlines are managed.
We always carry out work to our customers deadlines and requirements, while maintaining the highest possible standards. It is also sensible to ask how unforeseen delays are handled and how communication will work if plans need to change.
5. How do you manage cleanliness and disruption?
An extension does not have to turn your home into chaos. Good builders plan their work to minimise disruption and keep the site organised.
Ask how they protect existing rooms, manage dust, and keep shared areas usable. All our extensions are carried out in a tidy fashion with minimal disturbance, ensuring any other rooms of our customers living or working environment are not disturbed. This is especially important for families or those working from home.
6. Who will be on site day to day?
It is useful to know whether the person quoting the job will also be involved on site. Ask who your main point of contact will be and who supervises the work daily.
Clear communication builds trust. Knowing who to speak to if you have questions or concerns helps the project run more smoothly from start to finish.
7. How do you handle changes or additional work?
It is common for ideas to evolve once work begins. Ask how changes are priced and agreed.
A professional home extension service in Woking should explain their process clearly and provide written confirmation before any extra work is carried out. This helps avoid unexpected costs and keeps everyone on the same page.
8. Are you fully insured and compliant?
Insurance is not the most exciting topic, but it is essential. Ask about public liability insurance and any other relevant cover. You should also check that the builder works in line with current health and safety standards.
Reputable house extension builders in Woking such as ourselves will have no problem providing this information and explaining how safety is managed on site.
9. What level of finish can I expect?
Quality matters. Ask about materials, workmanship, and how finishes are checked before completion. A good builder takes pride in their work and is happy to explain the standards they aim to meet.
As a family run building company, CBC Builders takes pride in delivering friendly and reliable services to local homeowners. We focus on quality at every stage, from groundwork to final details.
10. Why should I choose your company?
Finally, ask what sets them apart. This gives you insight into how they see their own service and values.
For us, it comes down to working closely with our customers, respecting their homes, and delivering results we are proud to put our name to. We understand that an extension is a big investment and often a very personal project.
Making the right choice
Choosing the right builder is not just about price. It is about trust, communication, and confidence in the end result. By asking these questions, you can make a more informed decision and start your project on the right footing.
