Frequently asked questions about renovations

How does the renovation calculator work?

The renovation calculator is a tool that allows you to quickly obtain an estimated budget for the cost of a refurbishment. To perform this calculation, the calculator uses unit construction costs based on idealista's own knowledge which is updated periodically according to the Construction Sector Cost Index published by the Ministry of Transport, Mobility, and Urban Agenda.

Additionally, to provide you with the most accurate estimate possible, the calculator uses data from the Land Registry to display the characteristics of the property being refurbished. Although these data are shown by default, it is possible to modify them if you find they are incorrect.

How can I request a quote for my renovation?

You can request a quote through idealista.com/reformas. You can estimate the cost of a renovation using one of our calculators, and at the end of the process, the estimated cost calculation will appear. At the touch of a button, you can request a more detailed quote from a professional company.

How long will my renovation take?

The time it will take to complete a renovation will depend on various factors, such as the size and complexity of the project, the materials used, the availability of workers, and the level of customisation required.

Generally, smaller and simpler renovations, such as painting a room, can take only a few days to complete, while larger renovations, such as fully renovating a house, can take several weeks or even months.

Therefore, to know more precisely how long your particular renovation will take, it is best to consult directly with the company or contractor who will be carrying out the work. They will be able to give you a more accurate estimate of the time it will take to complete the project.

How much will my renovation cost?

The cost of a renovation can vary considerably depending on the type of project, the scale of the renovation, the materials to be used, and the level of customisation required.


Additionally, it is important to consider other factors that can influence the final cost of the renovation, such as the cost of labour, the necessary permits and licences, and any unforeseen issues that may arise during the renovation process.


Therefore, to get an idea of the cost of your renovation, you can use the renovation calculator on idealista to obtain an approximate estimate for your project. If you want a more detailed quote, it is best to request one from a professional company or contractor.

Is there a guarantee for the work done?

It is important to consider that the warranty for a renovation may vary from one company to another. Some companies may offer more comprehensive and extensive warranties than others, so it is advisable to verify the warranty conditions before hiring a company for your renovation.

The warranty may cover different aspects, such as the materials used, the quality of the work performed, or the agreed delivery deadlines.

What is the first thing to be renovated in a house?

The first thing typically renovated in a house is the essential systems, such as electricity and plumbing. These components are fundamental to ensuring the safety and functionality of the home. Assessing and updating the electrical wiring, sockets, switches, and pipes is crucial before tackling any other aspect of the renovation, as any issues with these systems can compromise the entire project and the habitability of the house.

After ensuring that the essential systems are in optimal condition, the most commonly renovated areas are the most used and visible parts of the home, such as the kitchen and bathrooms. These areas are not only vital for daily life but also have a significant impact on the property's value. Updating these areas with modern materials and functional designs is a priority for many homeowners when starting a renovation. If you are thinking of renovating your home, look for expert companies in your area and find the best professionals to carry out your project.

Is building or renovating more expensive?

Determining whether building or renovating is more expensive depends on various factors, such as the size of the project, the location, and the materials used. In general, building a new house tends to be more costly due to the need to acquire land, conduct land studies, obtain construction permits, and establish all basic infrastructure from scratch. Additionally, costs can significantly increase depending on the design and quality of materials chosen for the new build.

On the other hand, renovating an existing house can be more economical, especially if the building's structure is in good condition and doesn't require major changes. Renovations allow for the utilisation of existing infrastructure, which can significantly reduce costs. However, renovations can also become expensive if they involve updating essential systems like electricity and plumbing, or if significant reconfiguration of the space is needed. To get an accurate estimate and find the best option for your project, look for companies in your area and consult with construction and renovation experts.
