The 7 Mistakes to Avoid During a Total Renovation

Introduction

A total renovation is an exciting but complex project. After hundreds of projects across Belgium, we have identified the most common mistakes homeowners make.

Mistake #1: Underestimating the Budget

The golden rule: always plan a margin of 15 to 20% above your initial budget. Unforeseen issues are inevitable: hidden structural problems, mid-project changes, rising material prices.

Mistake #2: Neglecting Permits

In Belgium, many works require a building permit. Never start work without checking with your municipality. Penalties can be severe.

Mistake #3: Choosing Materials Based on Price Alone

Cheap materials often cost more in the long run. Quality tiles will last 30 years, cheap tiles will need replacing after 10 years.

Mistake #4: Not Planning the Sequence of Work

The order of work is crucial: demolition, structural work, electrical and plumbing, insulation, plastering, flooring, painting, finishing. Reversing this order can cause costly damage.

Mistake #5: Ignoring Energy Efficiency

Take advantage of a total renovation to improve insulation, replace windows and modernize the heating system. Regional premiums in Belgium can cover a significant portion of the costs.

Mistake #6: Wanting to Manage Everything Yourself

Unless you are a professional, entrust coordination to an experienced contractor. Managing multiple trades requires expertise that only professionals possess.

Mistake #7: Not Documenting the Project

Photograph every stage of the work. This protects you in case of disputes and allows you to track the actual progress of the site.
