Important issues include safety and regulations, and local laws. Another issue to consider are the energy savings that could be achieved as a result of a good renovation (for example, installation of double glazing and smart solutions, renovation of appliances that consume less energy, etc.), as this improves costs and helps preserve the environment.

In the event of a renovation, the occasion may be favorable to remove materials with asbestos and lead paints), replacing them with materials that are less harmful to human health and the environment.

Likewise, rainwater recovery systems could also be installed, as well as so-called dry toilets), and green roofs, etc.

It is important to note that to carry out all these types of actions included within a reform, it is necessary to have specialized technical profiles such as architects or technical architects whose supervision and planning allows to ensure the correct execution of the project work, in accordance with current regulations and the specific needs of the reform. In addition to regulatory compliance (local and/or national), the supervision of the project by a technician ensures that there will be no problems once the renovation is completed (bad odors, health problems such as lead pipes, environmental problems such as incorrect management of materials such as asbestos, etc.)[7]​.

Main problems during the renovation of a home:

• - Structural problems: appearance of cracks due to settlement of buildings or problems in structural elements such as beams and pillars (common in old buildings in coastal areas with a wooden structure).

• - Breach of regulations and permits: stoppage of works (permanent or temporary) with fines for not carrying out the necessary procedures according to the scope of the reform to be carried out.

• - Dampness and poor insulation: Not using insulation can generate mold and high energy bills, mainly in attics.

• - Improper disposal of toxic materials: both during the removal process and not removing them can harm the health of the inhabitants of the home and their neighbors.

• - Extra costs due to low quality materials: delays in the installation process of materials, breakages, early quality problems.

Technical progress today allows renovations and transformations that a few years ago were almost impossible to carry out.

• - The stripping techniques "Stripping (metal)") and stripping, as well as the initial diagnosis, already make it possible to reasonably guarantee the health of workers and future inhabitants, if necessary by removing harmful products that could be in the buildings.

• - For their part, ecomaterials allow the mobilization of fewer toxic materials than before.

• - And advances in computing make it possible to comfortably view plans in three dimensions, and estimate the solidity of, for example, a beam, a wall, or a column, in order to determine priorities and necessary work.

• - Infrared diagnostics allow detecting real or potential heat leaks.

• - And the energy diagnosis estimates the possible energy savings.

In any reform or renovation of a structure, consideration must be given to possible energy savings, as well as to any existing "Thermal Regulations (RT), which among other things define the energy performance levels") that must be implemented.

Wood

Wood is versatile and flexible, making it the easiest building material for renovations, and wood buildings can be redesigned to adapt to changing needs. Few homeowners or professional remodelers have the skill and equipment necessary to modify steel or concrete structures.

When analyzing the embodied carbon in building materials, wood is often labeled as the most sustainable. This is because it sequesters carbon which, if certified as sustainable, will significantly reduce the carbon embodied in buildings. This makes it a low-emission option as a construction material for a general building and for renovations. [8]​.

And finally, wood is without a doubt the material par excellence that best represents a vision of the "circular economy", since it reduces the environmental cost in terms of its disposal or destruction at the end of its useful life cycle, after numerous reuses. [9]​.

Plastic

Plastic has gained popularity in the renovation sector thanks to its versatility, durability and low cost. This material, primarily composed of synthetic petroleum-derived polymers, is used in a variety of applications, from coatings to thermal insulation and window components. Its waterproof properties make it ideal for humid environments such as bathrooms and kitchens, while its wear resistance and ability to imitate natural materials make it an attractive option for floors and walls.[10]​ Additionally, plastic is easy to maintain and clean, contributing to its preference in high-traffic areas. However, its environmental impact remains an issue of concern, which has driven the development of recyclable and biodegradable options in the renovation market.[11]​.
