Suspended balcony installation step by step: what to expect
Choosing to install a suspended balcony is only the first step. Most clients then want a practical answer: what exactly will happen, how long will it take and how much will the work affect everyday life in the apartment? The good news is that suspended balcony installation follows a clear, proven process that can be planned to minimise disruption for residents. In this article, we explain the entire process step by step – from the initial enquiry to handover of the completed balcony – exactly as we normally deliver it at HS ALUSYSTEM.
Why it pays to understand the entire process in advance
Balcony installation is not a single event, but a sequence of stages, each with its own purpose and timeframe. Knowing what happens next makes planning easier – whether you are arranging a holiday, cleaning or simply expecting to keep the windows closed for a few days. The better the initial phase is prepared – site survey, precise measurements and design – the smoother and faster the on-site installation will be. If you are still deciding which structural solution to choose, start with our guide on how to choose a suspended balcony and our overview of the factors that affect the price.
Step 1: Initial enquiry and no-obligation site survey
The process always starts with an enquiry – by phone, email or through the contact form. After an initial discussion about your requirements, we arrange a site survey. Our technician examines the façade, the building structure, any existing balconies or loggias and the available access routes, including the courtyard, pavement and proximity of neighbouring buildings. The survey is free of obligation and allows us to assess technical feasibility and recommend the most suitable anchoring solution. You can find our complete range of solutions on the suspended balconies.
Step 2: Precise measurements
Once both parties agree on the basic solution, we carry out precise surveying and construction measurements. Millimetre accuracy is essential for suspended balconies because each structure is made to measure for a specific building and must align exactly with the anchoring points in the façade or ceiling slab. During this visit, we also verify the condition and load-bearing capacity of the building structure. If the building requires it, samples may be taken or exploratory tests carried out.
Step 3: Design, structural assessment and quotation
Using the site survey and measurements, we prepare a technical design covering dimensions, glazing type, colour finish and anchoring method. More demanding projects – for example, installation where no balcony previously existed or where the building has an unusual structural system – also require a structural assessment confirming that the anchors can safely carry the load of the new structure. Only then do you receive a firm, project-specific quotation rather than a rough estimate. We also explain the differences in weight and anchoring loads between aluminium and other solutions in our article on aluminium versus steel railings.
Step 4: Permits and owners’ approval
For apartment buildings, approval from the owners is almost always required, usually through an owners’ meeting or the property manager. Depending on the scope of work, the project may also require notification of building alterations or a building permit from the local building authority. We will gladly advise you on this administrative stage and prepare the supporting documents so that the approval process runs as smoothly as possible. General information on when a building permit is required and when notification is sufficient is available, for example, on the Slov-Lexportal, which publishes the current wording of Slovak construction legislation.
Step 5: Bespoke manufacture of the structure
Once the quotation has been approved and the required permits obtained, we manufacture the balcony in our own production facility to the exact measurements of the building. Aluminium profiles are cut, welded and finished to the required dimensions; the structure receives its surface finish, usually powder coating, and any specified glazing is prepared. This stage generally takes several weeks, depending on the scope of the order and current production capacity. We confirm the exact timeframe after the contract is signed.
Step 6: Site preparation and delivery of scaffolding or an access platform
While the structure is being manufactured, we prepare access at the site – either a mobile elevating work platform, where space around the building allows, or scaffolding, particularly in confined locations, on higher storeys or where façade access is restricted. This stage may require temporary use of a pavement or parking spaces, which we arrange in advance with the relevant authority. Residents are informed beforehand so they know when equipment and scaffolding will appear outside their windows.
Step 7: Installation
This is the stage most people picture when they hear ‘balcony installation’, although it is only one part of the overall process. The completed structure is delivered to the site, anchored to the load-bearing parts of the façade or ceiling slab exactly as specified in the structural design, and then fitted with the railing and, where applicable, glazing. For a typical apartment, on-site installation usually takes several days. The exact duration depends on the scope of work, the number of balconies on the building and weather conditions. Anchoring and cutting are the noisiest operations, but we schedule them during reasonable daytime hours and minimise disruption to residents’ normal routines. Technical details of the installation solution are available on our suspended balcony installation.
Step 8: Quality inspection and handover
After installation, we inspect the anchors, glazing operation, seals and overall structural stability. We walk through the completed balcony with you, explain the maintenance requirements and hand over the necessary documentation. You can view examples of completed projects on our references.
How long does the entire process take?
From the initial enquiry to handover of the completed balcony, the full process usually takes several weeks to several months. Bespoke manufacture and obtaining permits generally account for most of this time, not the on-site installation itself. We can confirm a precise schedule only after the site survey and measurements because it depends on the scope of the project, the type of building and current production capacity.
How much will the installation affect everyday living?
Clients’ most common concerns are noise, dust and restricted access to windows during the work. In practice, the most disruptive stage is the installation itself, which lasts days rather than weeks. We work as cleanly as possible, tidy materials and tools at the end of each day, and restore the façade and surrounding area after completion. If you have specific requirements – for example, working from home in a room next to the balcony – we will discuss them in advance and plan the work to minimise disruption. We also explain how the structure is protected before installation in our article on powder-coated surface finisheswhich protect the structure before it is installed.
What to consider before installation begins
Before our equipment arrives, clear the area around balcony doors and windows, move flowerpots and other items from the existing balcony, and inform neighbours if the work will affect common areas of the building. If several balconies are being installed at once, appointing one contact person – such as the chair of the owners’ association – also helps us coordinate the schedule for the whole building. As with scaffolding used elsewhere in construction – see, for example, the information on scaffolding– this is a temporary access solution that is securely anchored to the façade.
Summary
Suspended balcony installation follows a clear sequence: site survey, measurements, design and permits, bespoke manufacture, access preparation, installation, and finally inspection and handover. Every stage has a purpose and timeframe, and thorough preparation at the outset is the best way to shorten the overall process. Our technicians guide you through every stage and keep you informed about what happens next.

Frequently asked questions
How long does the on-site balcony installation take?
On-site installation usually takes several days, depending on the scope of work, the number of balconies on the building and weather conditions. Preparation takes considerably longer: the bespoke structure is manufactured and permits are obtained before any equipment arrives on site.
Do we need to be at home during installation?
You do not need to be at home throughout the work. However, it is advisable to be available on the first day and at handover so that we can confirm access and formally hand over the completed balcony. We agree the exact schedule with you in advance.
Do we need a building permit to install a balcony?
In most cases, yes. Whether notification or a full building permit is required depends on the nature of the work and the local building authority. Approval from the apartment owners is practically always necessary. We help you prepare the required documents.
Will there be a lot of mess or noise during installation?
The work includes anchoring and, where necessary, cutting, which are noisier operations. We schedule them during reasonable hours, tidy materials and tools at the end of each day, and restore the area around the building once the work is complete.
Can installation also be carried out in winter?
In most cases, yes. However, we always adapt the date to the weather conditions and technical requirements of the specific structure. After the site survey, we propose a detailed schedule that is most suitable for you.
