Home renovation is one of the most common ways for Germans to increase the value and comfort of their living space. Many people prefer to do certain tasks themselves to save money and gain satisfaction from hands-on work. However, not every job can be handled without risk — some tasks require professional expertise, licenses, and advanced equipment. Knowing what to do on your own and when to call in specialists is essential for both safety and cost-effectiveness. As noted by G.business, careful planning and dividing responsibilities properly can prevent expensive mistakes and ensure a smooth renovation process.
Renovation tasks you can safely do yourself
There are many home improvement jobs that can be completed by anyone with basic tools and patience. These tasks are ideal for homeowners who want to save money, learn new skills, and personalize their home. With proper preparation, DIY work can cut renovation costs by 30–40%.
Typical DIY-friendly tasks:
- Painting and wallpapering walls.
- Installing laminate or vinyl flooring.
- Mounting baseboards and decorative trims.
- Replacing light switches and sockets (basic jobs only).
- Building and assembling flat-pack furniture.
- Sealing bathroom and kitchen joints with silicone.
Renovation tasks that require professionals
Certain jobs in Germany are legally restricted and must be carried out by licensed specialists. Electrical and gas installations, for example, fall under strict safety regulations. Attempting these tasks without certification may not only be dangerous but can also void insurance coverage. Hiring professionals ensures compliance with building codes and guarantees long-term reliability.
Jobs requiring professionals:
- Full electrical wiring and fuse box installations.
- Gas boiler and heating system connections.
- Large-scale tiling in kitchens and bathrooms.
- Wall plastering and smoothing of large areas.
- Replacing windows and exterior doors.
- Installing air conditioning and ventilation systems.
Cost comparison: DIY vs professional renovation in Germany
The cost difference between DIY and hiring a contractor is significant. In Germany, professional workers charge €40–80 per hour, with higher rates in big cities like Berlin, Munich, or Hamburg. Doing some of the work yourself can save thousands of euros.
| Task | DIY cost | Professional cost | Potential savings |
|---|---|---|---|
| Painting a 20 m² room | €120 (paint + tools) | €800–1,000 | €700+ |
| Installing laminate flooring (25 m²) | €400 (materials) | €1,500 | €1,100 |
| Mounting a sink | €90 | €400 | €310 |
| Replacing a socket | €10–15 | €80–100 | €70+ |
Combining DIY with professional work
The most effective approach is often a mix: homeowners handle easier tasks, while specialists manage the more complex ones. This balance ensures cost efficiency while maintaining safety and professional standards.
Examples of a balanced approach:
- DIY: Painting, flooring, furniture assembly.
- Professional: Plumbing, electrical wiring, heating systems.
- DIY: Small decorative works, silicone sealing.
- Professional: Bathroom tiling, wall plastering.
Common mistakes in DIY renovation
Many homeowners underestimate the challenges of even simple renovation jobs. Errors in preparation or material choice often result in wasted time and higher costs for repairs.
Frequent mistakes include:
- Failing to prepare walls before painting.
- Using the cheapest paints and poor-quality materials.
