How much does it cost to enclose a balcony in 2026? Check the current prices, examples of completed projects, typical balcony dimensions and the factors affecting the cost of enclosure. Find out what determines the cost of a balcony enclosure, which materials are most commonly chosen, and what the typical dimensions of balconies in multi-family buildings are.

If you’re planning to enclose your balcony, your first question is probably about the cost. And rightly so. Depending on the solution chosen, the cost can start at a few thousand zlotys for materials for self-assembly and exceed 17,000 zlotys (gross) for a comprehensive service including measurement, manufacture and installation. The differences stem not only from the size of the balcony, but also from the type of material, the height of the structure, the number of sections and the complexity of the installation.

In this article, we show the actual price ranges based on projects carried out by Otwierane.pl in 2026. This will make it easier for you to estimate your budget before you submit the form.

• Most balcony enclosures cost between 10,000 and 12,500 zł gross,
• Small balconies can be enclosed from as little as around 7,500 zł gross,
• Large balconies and loggias can cost over 17,000 zł gross,
• The most commonly chosen material is aluminium slats,
• materials usually account for between 75 and 85% of the total investment,
• The cost of the fitting depends on the dimensions, the material, the number of partitions in the structure and the method of installation,
• Before choosing a contractor, it is worth checking their previous projects, the scope of their quote and their experience in balcony enclosures.

What are the typical dimensions of balconies in Poland?

Although every building is different, we regularly come across similar dimensions when carrying out valuations.

The most common issues in multi-family buildings are:

• small balconies – up to about 2 m wide,
• medium-sized balconies – between approximately 2.5 and 3.5 metres wide,
• large balconies and loggias – over 3.5 metres wide or requiring construction extending to the full height of the storey.

This breakdown makes it possible to estimate the cost of the development even before the measurements are taken.

How much does it cost to enclose a balcony in the 2026 season?

In 2026, the cost of enclosing a balcony usually ranges from around 7,500 to 18,000 zł gross. The price range is wide because the final quote depends on the balcony’s dimensions, the height of the enclosure, the material chosen, the number of sections, the colour scheme and the method of installation.

Based on projects carried out by Otwierane.pl, it can be assumed that most balcony enclosures in blocks of flats and apartment blocks cost between 10,000 and 12,500 zł gross.

How much does a small balcony enclosure cost?

In the case of small balconies found in blocks of flats, the cost of enclosing them is usually between 7,500 to 9,000 zł gross.

These are usually balconies enclosed on one or both sides, fitted with movable aluminium or wooden slats.

How much does it cost on average to enclose a balcony?

The largest group of projects consists of balconies approximately 2.5–3.5 m wide. For such projects, the cost usually ranges from 10,000 to 12,500 zł gross.

This is currently the option most frequently chosen by flat owners in multi-family buildings.

How much does it cost to enclose a large balcony?

Large balconies and loggias require more material and a more complex structure.

For projects of this kind, the cost is usually between 16,000 to 18,000 zł gross.

Such structures are often installed in apartment blocks and on corner balconies, where protection from the wind and increased privacy are particularly important.

How much do the materials cost, and how much does the installation cost?

People planning to enclose their balcony often wonder what proportion of the budget is allocated to materials and what proportion to the installation service.

Based on projects carried out by Otwierane.pl, it can be assumed that, for medium-sized and large balconies, materials usually account for around 75–85% of the total project cost. The remainder covers technical surveying, preparation of components, transport and installation.

For small balconies, the proportion of installation costs is usually higher. This is because the costs of travel, taking measurements and organising the work remain similar regardless of the size of the installation.

That is why a small balcony enclosure is not always proportionally cheaper than a larger project.

Purchasing materials or a turnkey project?

Buying the materials yourself may be a good option if:

• you have experience in assembly work,
• you are able to carry out measurements on your own,
• you have the right tools,
• You want to keep the cost of the investment down.

A comprehensive approach works best when:

• Do you want a single contractor to be responsible for the entire process,
• the balcony has non-standard dimensions,
• The installation must be adapted to the existing balustrade or façade,
• You want to avoid the risk of measurement and installation errors.

There is no one-size-fits-all solution. In practice, some customers opt to carry out the installation themselves using ready-made kits, whilst others choose a service that includes measurement, manufacture and installation.

What materials are most commonly chosen for balcony enclosures?

The price is influenced not only by the size of the balcony, but also by the material chosen.

Aluminium

Movable aluminium slats This is currently the most popular option.

Pros:

• no need for waterproofing,
• resistance to moisture and UV radiation,
• dimensional stability,
• the option to match the colour to the façade and joinery.

The most popular colours are RAL 7016 and RAL 9006.

Wood

Removable balcony boards They are mainly chosen by people who want their buildings to have a natural look.

However, it is important to bear in mind that it requires periodic maintenance and the renewal of its protective coatings.

Woodgrain slats

Woodgrain slats This solution combines the look of wood with the durability of aluminium.

The Winchester and W2P22 designs are the most popular choices. In most cases, wood-effect finishes are more expensive than standard colours from the RAL colour chart.

Not sure which fabric to choose? Read the guide „Balcony enclosures – wood, aluminium or polycarbonate?”, in which we compare the durability, maintenance requirements, appearance and costs of the various solutions.

Every balcony requires a bespoke approach. They vary in width, building height, wall layout and degree of exposure to the wind. Below you will find examples of projects completed by Otwierane.pl using wood, aluminium and wood-effect slats.

• Balcony cladding with wood-effect slats – Bialystok
• Wooden balcony cladding – Warsaw Bialoleka
• Corner wooden balcony enclosure – Olsztyn
• Enclosing a wooden balcony from the railing to the ceiling – Ząbki
• Aluminium balcony enclosure with wood-effect slats – Pruszków

What factors are taken into account when valuing a balcony enclosure?

The cost of enclosing a balcony does not depend solely on its size.

When preparing a quotation, we analyse:

• the width and height of the balcony,
• the number of walls to be fitted with units,
• type of material,
• colour scheme,
• the number of structural divisions,
• the need to use additional profiles,
• installation method,
• access to the site.

That is why two balconies of similar dimensions may be valued differently.

How do you choose a contractor to fit out your balcony?

Price balcony enclosure services It is important, but it should not be the sole criterion for selecting a contractor. Balcony cladding is in use all year round and is exposed to wind, rain, snow and UV radiation.

Before making a decision, it’s worth checking:

• the contractor’s actual projects,
• experience in fitting out balconies and terraces,
• the quality of the materials used,
• scope of the valuation,
• the method of carrying out technical measurements,
• the possibility of servicing and expanding the structure in the future.

It is also good practice to compare several quotes and to consider not only the price, but also the scope of work and the technical solutions employed.
