A well-renovated terrace is the most used room in your house between May and October. In Mallorca, we live outdoors, so every square meter counts. That's why a well-planned terrace renovation in Mallorca—with waterproofing that withstands sun and salt, non-slip flooring, and details like a pergola or good lighting—completely transforms how you enjoy your home. We are a family business with over three generations of experience renovating homes on the island, and we do it at a fixed price, with deadlines that are met.
What does a complete terrace renovation in Mallorca include?
A complete terrace renovation encompasses everything from deciding whether or not to remove the existing paving to making it ready for use: waterproofing, new flooring, drainage slopes, lighting, and, if requested, shade and enclosure. We don't build new structures; we renovate what you already have. This is what we typically address when a terrace undergoes a complete renovation complete renovation of your home:
- New waterproofing or reinforcement of the existing one, with correction of slopes.
- Non-slip outdoor flooring: porcelain stoneware, technical decking or microcement.
- Drains, sumps and sealing of junctions with walls and railings.
- Pergolas, awnings and lightweight aluminum and glass enclosures.
- Exterior lighting, electrical outlets and water point.
- Penthouse terraces and common areas of homeowners' associations.
How we protect your terrace from Mallorca's coastal climate
The island's climate is harsher on terraces than you might think. Intense summer sun, high salt air near the coast, and torrential autumn rains. This combination creates micro-cracks, and when there's a house below, the leaks end up on the neighbor's roof.
The regulations make it clear Technical Building Code, document DB-HS1 it requires a minimum slope of 1% on covered terraces and 1.5% on those exposed to rain, so that the water runs off and does not stagnate. In areas like Portitxol or El Molinar, we choose membranes designed for marine environments, not the cheapest option in the catalog.
Which waterproofing system should you choose for your terrace?
There's no single best system: it depends on the size, whether there's a house below, and how many years you want to be able to forget about it. Flexible mortar will do on a small terrace; an attic overlooking the bedrooms requires something much more substantial. These are the reference prices for 2026, cross-referenced with industry guides such as Humedades.com:
| System | Durability | Price 2026 (€/m²) | Ideal for |
|---|---|---|---|
| Flexible cementitious mortar | 8–12 years | 25–40 | Small terraces, under tiles |
| Liquid polyurethane membrane | 15–20 years | 25–45 | Seamless walkable surfaces |
| Asphalt or PVC sheeting | 15–25 years | 35–55 | Rooftops and large surfaces |
| EPDM Rubber | 25–30 years | 40–70 | Demanding penthouses and roofs |
However, that number isn't the final price. We also need to add the cost of preparing the surface and decide on the key question: do we remove the existing paving or waterproof it over it? We'll explain it all during the visit, with both figures in front of you.
Which non-slip outdoor flooring works best on a terrace?
On a terrace, the flooring needs to be attractive and, above all, safe when wet. We look for finishes with a high slip resistance rating (class 3, R11 or higher), essential if there's a pool, outdoor shower, or children. These are the three options we install most often:
- Non-slip outdoor porcelain stoneware: The all-terrain vehicle. It withstands the sun without fading and its installation costs around €35–40/m² according to data from Habitissimo by 2026.
- Technical flooring (WPC or composite): Warm to the touch and splinter-free, between €25 and €60/m² installed. Perfect for rooftop terraces with a batten system.
- Continuous microcement: Seamless, modern aesthetic, ideal when you want a clean and minimalist-looking surface.
The truth is that many customers come in thinking only about the color and leave understanding the difference between a floor that is slippery and one that is not.

Why a penthouse or community terrace requires more planning
A penthouse isn't a regular terrace. Often, it's the roof of the entire building, so a leak affects the whole property, and responsibility is shared. And if you want to enclose it or install a permanent pergola, you'll need a building permit from the local council. In a penthouse, waterproofing takes precedence over aesthetics.
If you're considering closing the space, first look at the permits to enclose the terrace of a penthouse in Mallorca and, in general, What you can and can't do on terraces and balconies. We can guide you and we also renovate entire communal terraces, coordinating with the building manager.
Frequently asked questions about terrace renovations in Mallorca
How much does it cost to renovate a terrace in Mallorca in 2026?
A standard terrace renovation of approximately 20 m² costs between €3,000 and €8,000 in 2026, including waterproofing, non-slip flooring, and basic details. Budget-friendly options start from €1,500, while premium options, with motorized pergolas and lighting, can reach €12,000. At Tecnic Project, we offer fixed-price labor, so you know the total cost before we begin.
How long does terrace waterproofing last?
The durability of a terrace waterproofing system depends on the type of system used: a flexible cementitious mortar lasts between 8 and 12 years, a polyurethane membrane between 15 and 20, and a PVC sheet or EPDM rubber between 25 and 30 years. In Mallorca, with the salinity and radiation of the coast, a high-end system is worthwhile.
Is it necessary to lift the paving to waterproof a terrace?
It's not always necessary to remove the paving to waterproof a terrace. If the subfloor is sound and the slopes are correct, a liquid membrane can be applied directly over the existing surface, saving time and money. However, when there are deep cracks, accumulated moisture, or a drainage problem, removal is advisable. We'll decide during the site visit, reviewing both options and their prices.
What non-slip flooring is best for a terrace in Mallorca?
For a terrace in Mallorca, outdoor porcelain stoneware with an R11 slip resistance rating is the most balanced option: it withstands the sun without fading, is safe when wet, and requires minimal maintenance. If you're looking for warmth underfoot, composite decking works very well on rooftop terraces. And seamless microcement is ideal for a clean, jointless aesthetic.
Do I need a permit to renovate or enclose the terrace of a penthouse in Mallorca?
Renovating the flooring or waterproofing of your terrace doesn't usually require a major building permit, but enclosing, covering, or modifying the facade does. In penthouses and apartment buildings, municipal regulations and the building's bylaws come into play. We recommend checking the permits before starting any plans; we can guide you and coordinate the technical aspects of the application.
When NOT to renovate your terrace yet
Being honest is also part of the job. There are times when it's best to wait.
- If there is an active leak to the floor below: First, locate and cut off the source; new paving over an unsolved problem is money wasted.
- If the building has a pending assessment or facade renovation: It's best to coordinate both projects to avoid doing things twice.
- If you are going to enclose the terrace but are not sure about the permit: Confirm the permit before investing in finishes that may need to be modified.
