Rehabilitation of buildings - Judicial expert of the construction industry

Did you know that a well-refurbished building can last decades longer and increase its value significantly? If you are here, you are probably wondering how to bring an old or deteriorated building back to life. Rehabilitating buildings not only improves their appearance, but also ensures their safety, functionality and protection against future damage. In this article, we'll explain everything you need to know to get off to a good start.

What is building renovation?

The rehabilitation of buildings is the process of renovating, repairing or upgrading an existing building to restore its original features or to adapt it to new needs. This process ranges from structural interventions to aesthetic adjustments, with the aim of ensuring that the building is safe, functional and attractive.

Unlike a restoration, which seeks to return the building to its original state while respecting its historical value, a refurbishment may include modern changes to make it more efficient or suitable for current regulations.

Main reasons for rehabilitating a building

1. Structural safetyOver time, building materials wear out. Repairing cracks, reinforcing foundations or replacing damaged parts avoids major risks.
2. Improving waterproofingWater leaks are one of the most common problems. Good waterproofing protects the building and prevents future damage.
3. Energy efficiency: Incorporating improvements such as thermal insulation and high-efficiency windows reduces energy consumption and heating and cooling costs.
4. Heritage conservationIn old or historic buildings, rehabilitation is key to preserving their cultural and architectural value.
5. Value enhancementA refurbished building is more attractive to live in and to sell or to buy. rent.

Rehabilitation process: step by step

1. Initial inspection and diagnosis

Before any work begins, a specialised surveyor assesses the condition of the building to identify structural, waterproofing or installation problems. This analysis is crucial in order to design an appropriate action plan.

2. Feasibility study

Here it is decided which areas require intervention, how much it will cost and whether the building can withstand certain modifications. This step is essential to avoid surprises during the work.

3. Structural rehabilitation

If there is severe damage to foundations, beams or walls, they are reinforced or replaced. In many cases, seismic protection systems are also installed.

4. Improvements in waterproofing

Techniques and materials such as waterproofing membranes, roof treatments and joint sealing are applied. This prevents leaks that could cause mould or deterioration.

5. Restoration and finishing

At this stage, the appearance of the building is taken care of, restoring façades, carpentry or decorative elements, always respecting the original design or adapting it to new needs.

Differences between rehabilitation and waterproofing

Although waterproofing is an important part of rehabilitation, they are not the same thing. Waterproofing focuses exclusively on protecting the building against water ingress, while rehabilitation encompasses structural, aesthetic and functional repairs.

When is building renovation necessary?

• Visible cracks on walls or ceilings.
• Water leaks that damage walls and floors.
• Aesthetic wear and tear such as peeling paint or deteriorated materials.
• Outdated regulations in terms of safety or accessibility.

Building renovation not only ensures the safety and functionality of a building, but also protects your investment in the long term. From improving waterproofing to restoring historic elements, this process is essential to extend the life of any building.

If you are considering rehabilitation, remember that each case is unique and having the support of experts, such as a building surveyor, is key to getting the best results.
