Frequently asked questions

The cost of building an extension typically ranges between €15,000 and €50,000, depending on the size, finish, and complexity of the job. For a standard extension of 5 by 2.5 meters, the costs range between €50,000 and €70,000. At Zoofy, rates are based on averages charged by professional handymen, so you won't face any surprises. The rate includes fixed costs from the handyman, and there are no call-out charges. That way, you always know what to expect.

On average, building an extension takes between 4 and 8 weeks, depending on the complexity of the job and the experience of the handyman. A simple extension can be completed more quickly, while a custom-built extension or one with many slanted walls may take longer.

A handyman ensures your extension is professionally and efficiently built so you don’t have to worry about a thing. The process includes the following steps:

  • Preparation: The handyman checks whether all necessary materials and tools are available, such as building plans, permits, and supplies.
  • Foundation and structure: The foundation is laid, and the structure of the extension is built according to specifications.
  • Installations: If required, electrical wiring, plumbing, and other systems are installed.
  • Finishing: The handyman takes care of the final touches, such as installing windows and doors, adding insulation, and finishing walls and floors.
  • Cleanup: After the build, the handyman ensures that all materials and tools are cleaned up. You are left with a fully completed extension, ready for use.

At Zoofy, all handymen are thoroughly screened for skill and reliability. You can read reviews and ratings from previous customers. Zoofy only works with handymen who maintain an average rating of 9.2 or higher, ensuring you get a true professional. Transparent pricing and the absence of call-out charges also help build trust.

With Zoofy, you can count on aftercare and warranty once your extension is completed. After the job, you’ll receive an invoice via Zoofy for secure payment. You can also opt for additional paid warranty for extra peace of mind. For maintenance or issues, you can always get back in touch with Zoofy.

Yes, at Zoofy we do our utmost to always find a suitable handyman for building your extension. We have a large network of experienced professionals. If we unexpectedly cannot find someone, we’ll inform you right away.

Payment is made through Zoofy. Once the handyman has completed your extension, you’ll receive a payment link by email. We also offer the option to pay easily and securely via QR code after the job is done. This ensures a safe and hassle-free payment without cash.
