How to undertake the rehabilitation of facades?

The rehabilitation of facades involves the planning and implementation of a large-scale architectural and construction project. It is carried out, for example, when the materials or structure of this part of a building are very deteriorated. Another reason to undertake it is to provide greater energy efficiency. To develop it properly, a whole set of technical, legal, organizational, budgetary, aesthetic, and time considerations must be taken into account.

What is the rehabilitation of facades?

This is a construction project aimed at repairing the poor condition of this very important part of buildings. Indeed, facades serve to protect the interior of a building and also fulfill an aesthetic function. Therefore, it is essential, both for the image and the well-being and safety of the inhabitants, that they are in perfect condition. In most cases, they are carried out for the following reasons:

• Deterioration of the walls that form it or of any of its components (cornices, tiles, balconies, decorative elements, etc.).
• Appearance of moisture or bulges, affecting interior comfort or posing a danger of accidents.
• Loss of insulation and optimal conditions for watertightness and heating.

Generally speaking, undertaking these works is an excellent opportunity to make significant changes, such as improving waterproofing and insulation levels, and renewing certain systems, such as electrical, heating, or ventilation.

How long does it take to rehabilitate facades?

There are many factors that condition the completion time of an intervention of these characteristics. However, the municipal permits for it usually have a validity of three months. Therefore, within this period, all necessary actions must be undertaken and a good finish achieved.

Despite this average, experience tells us that a large number of unforeseen events usually arise that delay completion. Problems may arise from the structure, imperfections, material quality, arrival of orders, last-minute changes, etc.

In addition, it must be taken into account that activity in these cases affects the immediate environment. For this reason, possible adaptations or changes arising from them must be anticipated.

How to improve the facade of a building?

The rehabilitation of facades can represent an opportunity to improve the entire aesthetics, comfort, and energy efficiency of the building. Here are some aspects to consider:

• Renew all the material that covers it and eliminate moisture.
• Achieve smoothing and symmetry of all parts.
• Make necessary changes for greater use of sunlight, avoiding excess at certain times of the day.
• Integrate considerations from passive house designs, so that ventilation and natural light are increased and electrical consumption is reduced.
• Undertake appropriate actions to guarantee the watertightness, insulation, and waterproofing of the building.

Aesthetic or conservation aspects of historical and artistic heritage can also be included, in the case of some old facades.

In short, the rehabilitation of facades requires mobilizing a large amount of resources, time, materials, and workers. No doubt, there are many aspects to consider that require specific actions. Also, one must think of the well-being of the environment and the neighbors of the building. In this sense, all actions must be planned to cause the least possible impact.
