Adding a house extension is a significant investment, so choosing the right builder is crucial to ensure your project is completed successfully. In this guide, we’ll walk you through the steps to find reputable builders, avoid rogue traders, and ensure your extension project runs smoothly.

1. Start with Research

Begin by researching local builders in your area. Look for extension builders with experience in home extensions, loft conversions, or garage conversions.

2. Seek Recommendations

Recommendations from trusted sources can help you narrow down a list of good builders. Be sure to ask about their experience, the quality of the work, and how well the builder handled project management and site restrictions. A reliable builder with a proven track record will give you peace of mind.

3. Check Online Reviews

Look for feedback on previous work, adherence to completion dates, and how they managed customer references and communication. Be cautious of builders with numerous complaints about poor workmanship or missed deadlines. Online reviews are particularly helpful when trying to find a reputable builder in your local area.

5. Review Previous Work

Reputable builders should provide a portfolio of house extensions they’ve completed, including kitchen extensions, loft conversions, and garage conversions. If possible, visit these projects to assess the quality of the workmanship and materials used. This is a key step in choosing the right builder for your project.

6. Contact Previous Clients

Ask for contact details of previous customers and speak with them about their experience. Questions to ask include:

Was the builder reliable and professional?
Were they transparent about payment terms and schedules?
Did they stick to the agreed completion dates?
Were there any issues with waste disposal or site restrictions?

Hearing directly from previous clients will help you identify good builders for your project.

7. Obtain Multiple Quotes

Always get quotes from at least three builders. Compare the builders’ quotes based on the following:

Detailed full specification of the project.
Payment schedule and milestones.
Working hours and availability.
How they handle waste disposal and site restrictions.

Avoid choosing the cheapest quote without reviewing the builder’s trading history and reputation, as the wrong builder could lead to poor workmanship or delays.

8. Discuss Building Regulations and Planning Permission

For permitted development projects, ensure that your builder understands the building regulations and that drawings suitable for approval comply with local regulations. This is particularly important for master builders, who are expected to follow all legal requirements.

9. Check for a Written Contract

A written contract protects both you and the builder by clearly outlining:

Scope of the build service.
Agreed completion dates.
Payment terms and payment schedule.
Responsibilities for waste disposal and building works.

The contract should also include clauses for project management, site restrictions, and contingency plans.

10. Evaluate Communication Skills

A good working relationship with your builder is essential for a successful project. Choose a local builder who prioritises open communication and keeps you updated throughout the project. This will ensure smooth collaboration with your master builder or contractor.

11. Avoid Rogue Traders

To protect yourself from rogue traders, look out for these warning signs:

Refusal to provide a written contract.
Demands for large upfront payments.
Lack of credentials or correct insurance.
Unwillingness to share customer references or examples of previous work.

12. Inspect the Project During Construction

Ensure the builder adheres to the agreed specifications, follows the building regulations, and addresses any issues promptly. Regular inspections help confirm that the construction industry standards are being met.

13. Final Checks Before Completion

Before the project concludes, ensure the builder has:

Met the agreed completion dates.
Provided a clean and safe site with proper waste disposal.
Delivered the extension project as per the contract specifications.

Verify all relevant certificates for work completed, such as electrical installations or plumbing, and confirm that the work complies with building control requirements.

Conclusion

Finding a good builder for a house extension requires thorough research, checking credentials, and reviewing examples of previous work. Look for master builders, local builders, or contractors affiliated with trade associations for added assurance.

Remember to prioritise open communication, a written contract, and compliance with building regulations. By taking these steps, you’ll ensure your extension project is in safe hands, whether it’s a kitchen extension, loft conversion, or garage conversion.

Take your time to choose a builder carefully, and you’ll enjoy your new space without the stress of delays or unexpected costs.
