What is a fair price for renovation work?

When we think about carrying out reforms in our home, one of the most important doubts that appear is: How much is it going to cost? Or what is the right price for what I want to do?
Here we give you a guideline so that you can calculate yourself how much it is going to cost.

The room to renovate

First of all, it must be clear that some rooms are more expensive than others.
Wet rooms such as kitchens and bathrooms include all kinds of installations, coverings and furnishings, as well as various types of lighting.
Rooms such as bedrooms or living rooms usually have a basic floor covering material and a finish for walls and ceilings, which usually includes plaster and paint.
Although it is true that we can invest large sums of money in the furnishing and lighting of these rooms, if we stick to simple or medium-priced solutions, the investment per m2 is less than in kitchens and bathrooms and can even be half as much.

Demolition work

Demolition is an apparently easy job, as it can be done by anyone without any knowledge of construction or reforms in general, but if we stop to think about it a little more carefully, there are some tips that perhaps we should take into account and that will have a direct impact on the price:
You need staff with physical strength and at the same time work carefully so as not to damage what you are going to keep.
You need to have prior protection of the common areas of the building, as well as the areas of the house that are not to be intervened in.
Time must be allowed for the separation of demolition material for later recycling.
The cost and taxes for recycling of each type of material should be taken into account.
It must be taken into account whether the demolition material or objects will reach the public road manually or with the help of machinery (platforms, forklifts or lifts).
In demolition there is hardly any investment of material, but there is an investment of labour, so we can count how long it may take to dismantle, chop or demolish, carry the remains and debris to the public road and have it delivered to the authorised landfill.
So let’s take into account the protections, the proportional part of the workers’ salaries, the transport and recycling fees, and to this we must add the depreciation of the machinery used and the workers’ personal protective equipment.
With some exceptions, demolition work usually represents between 5 and 12% of the total cost of the renovation, depending on the time and difficulty of the tasks to be carried out.


These include water, waste disposal, gas, heating, air conditioning, ventilation, air or smoke extractions, electricity, television, telephone, fibre and often include changes of antenna, doorbell or entry phone.
Each of them requires specialised personnel, tools, protections and, of course, specific material and machinery for each type of installation.
But also, unless the installations are going to be visible, it will be necessary to have a bricklayer to open the way for the pipes, conduits and cables, and then close them, making sure that they are not noticeable once the work is finished.
In general, in a renovation we should reserve between 20 and 30% of the total costs for the installations.
To these costs, we must add the price of the sanitary ware, taps, complements and accessories necessary for their correct installation, whose price depends on the brand and the design of the product, there being enormous differences that will determine the quality and the final appearance of the reform.

The cladding

The price of labour depends on the nature of the tiling, the format and the difficulty of laying it. In the case of ceramic tiles, small and large format pieces are the most expensive to lay and those of manageable size (30×60 cm for example) are the most profitable. The price for these works is usually between 35 and 60 € /m2, but it varies enormously if the covering to be laid is paper, paint, microcement, textiles, etc.
To this cost must be added the cost of the cladding material (counting extra because we will certainly have wastage), the finishing material for the joints and the finishing material if necessary, as well as transport, tools and special work such as mitre cuts or specific techniques for the application or installation of each type of cladding.
The range of prices for these materials is very wide and can go from €20/m2 to as low as you want to go. Without going into details, an average price could be between 30 and 100 €/m2, to which we must add the aforementioned labour costs.

The furniture

We usually distinguish between fixed furniture, which is normally included in the price of the renovation work, and mobile furniture, which normally forms part of the decoration project.
The first group includes kitchen furniture, washbasin units and built-in wardrobes, while the second group includes tables, chairs, sofas and beds, among others.
Again, we can find brands such as Ikea, which offers well-designed solutions at a very competitive price, and others that stand out for their choice of materials or their exclusive design at much higher prices.


As with the furniture, it is common to differentiate between the lighting that is installed during the construction process and the lighting that is installed once the renovation work has been completed. The range of possibilities, both in terms of form and price, is enormous and impossible to quantify without determining specific brands and models.

Precio reforma

n addition to these basic items, which are present in all renovations to a greater or lesser extent, there are also the costs of changing the layout, exterior carpentry, kitchen and bathroom worktops, glass for mirrors and screens, electrical appliances and an endless list of materials, construction solutions and specialists that will vary in each case and can significantly affect the total cost of the renovation.
In short, it is almost never possible to determine the price of what a reform is going to cost a priori, without determining what it is going to consist of or what materials are going to be used. That is why, if you have a tight budget, the best thing to do is to plan the renovation the other way round and start planning on the basis of the cost that cannot be exceeded.
To obtain the best possible result, according to each type of space and the needs and budget of each one, it is necessary to know which profile of workers is the most suitable and which materials will provide the best quality/price ratio, meeting all the characteristics required for each case.
It is for this reason that it is complex to know how much a reform costs and very difficult to ensure that the costs do not exceed the planned budget. After our 18 years of experience carrying out reforms of all types and for all types of clients, we can affirm that the right price for a reform work can only be obtained when the space is known in depth, the needs that must be covered and the offer of possibilities both in terms of construction professionals and in terms of materials and products that we find in the market all over the world.
All of this means that hiring an experienced interior designer trained in the field is perhaps the best option to get it right and avoid many surprises and setbacks both during the construction process and in the final result.
