How Much Does It Cost to Change Interior Doors in Cádiz? 2026 Prices
Changing an interior door in Cádiz costs between €150 and €450 per installed unit depending on the door type and hardware, and renovating all the doors in an average flat comes to between €1,500 and €2,500. It is one of the renovations that most transform the look of a home with the least building work and budget, especially in the 1960s–80s flats so common in the Bay.
In this guide we give you prices updated to 2026 based on real projects in Cádiz city, San Fernando, Chiclana and the rest of the province, with the different door types, when it pays to lacquer the ones you already have instead of replacing them, and what can be done without building work.
What affects the price of an interior door
The price of changing an interior door depends mainly on the leaf type (hollow, solid or veneered), the finish (lacquer, melamine or wood), the opening system (hinged or sliding) and the condition of the sub-frame. If the old door's sub-frame is in good condition and level, it can be reused and only the leaf and visible frame are changed; if not, it has to be replaced, which raises the labour cost.
Types of interior door
The hollow door (with a honeycomb core) is the lightest and cheapest, perfect for bedrooms and dry areas. The solid-core door insulates better against noise and is more robust, ideal for separating day and night areas. In finishes, white lacquer is the most in-demand for its brightness, melamine is the most durable and economical option, and wood veneer adds warmth.
- Hinged: the traditional type, the cheapest and simplest to install. It needs swing room.
- Surface sliding: it slides on a track over the wall. It saves the swing room without building work, ideal for narrow hallways.
- Pocket sliding (cassette): the leaf hides inside the wall. It is the cleanest look, but requires building work to fit the cassette, so it is considerably more expensive.
And what if you want to separate two spaces without losing light —kitchen and living room, a home office or a gallery? Then a glass door is a great alternative to a solid leaf: a sliding glass panel, or even a glass curtain like the terrace ones for large openings, lets light through and adds a sense of space without giving up the ability to close off the passage. It is a very popular option in open-plan flats in Cádiz.

Change the doors or lacquer the ones I have?
If your doors are structurally sound, with no deep dents or humidity warping, lacquering them makes them look brand new for considerably less money: around €120–200 per leaf versus the €150–400 it costs to replace one. If they are damaged, swollen by moisture or you want to change the style completely (for example, going from dark wood to smooth white lacquer), then it pays to replace them. On the visit we check each door and advise you on the most cost-effective option.
Watch out for the Cádiz humidity: in ground floors and flats near the sea, cheap hollow doors tend to swell and peel at the bottom. For damp areas (bathrooms, entrances) it is worth a solid leaf or one with a reinforced edge, which withstands the salty environment far better.
Can the doors be changed without building work?
In most cases, yes. If the sub-frame (the wooden liner embedded in the wall) is in good condition, we change only the leaf, the visible frame and the architraves without chasing the wall or creating rubble, and for a whole flat the job is done in a day. The exception is the pocket sliding door: as the leaf hides inside the wall, it does require building work to fit the cassette.
Factors that affect the price
- Number of doors: the more units, the better the price per door, because the survey and travel are spread across them all.
- Pocket sliding door: fitting a cassette inside the wall can double the cost of that door versus a hinged one, because of the building work involved.
- Non-standard sizes: in Cádiz old-town flats it is common to find openings taller or wider than standard, which require a bespoke door and raise the unit price.
- Extras: glazed panels, acoustically insulated doors, designer handles or concealed hardware add cost on top of the base door.
Timelines and installation process
After the survey, the doors are made to measure in 2–4 weeks. Installing a whole flat (5–7 doors) is normally done in a single day if the sub-frames are reused, and in a couple of days if they need replacing or there are pocket sliding doors. We remove the old doors and leave the home clean the same day.
Is it worth changing the doors?
Changing the doors is one of the renovations with the best cost-to-impact ratio: for €1,500–2,500 a whole home gains light and updates its look at once, something that shows a lot when selling or renting. If your doors are only dated in colour but structurally sound, lacquering them is even more cost-effective. If they are damaged or you want a total change of style, replacing them is the best investment.
