Apartment Building Ventilation Installation

Ventilation installation in an apartment building means creating a complete air exchange solution from the ground up or carrying out a major reconstruction of the existing system so that airflow is controlled and meets modern standards.

Aero Grupp provides full-service ventilation installation across Estonia. Our goal is to deliver a reliable ventilation solution that matches the needs of the building and is properly documented.

What problems usually need to be solved?

Ventilation work in apartment buildings usually becomes necessary when complaints become regular and indoor conditions in the flats start to feel genuinely uncomfortable.

In apartment buildings undergoing renovation or reconstruction, the existing system is often based on natural ventilation. This, however, depends heavily on temperature differences and wind conditions, which means the air exchange is not controlled.

During renovation, windows, doors, and roofs are typically replaced, and the façade is insulated.

As the building becomes more airtight, incidental air exchange is reduced. If ventilation is not addressed at the same time, existing problems tend to become worse.

The most common issues in buildings with natural ventilation are very clear: rooms feel stuffy, mould and moisture begin to appear, and odours travel between flats.

Results that matter today and ten years from now

The real value of ventilation works lies not only in the technical solution itself, but in how it affects the apartment building’s indoor climate, day-to-day comfort, and future operating costs.

Better indoor air quality

When air exchange is properly balanced, CO2 levels and indoor pollutants stay under control. This has a direct effect on wellbeing, sleep quality, and fatigue.

Better moisture control and lower risk of mould

A properly designed and well-built ventilation system helps keep humidity levels stable and reduces the conditions that allow mould to develop.

Less odour transfer between flats

When airflow is directed correctly, cooking smells, smoke, moisture, and other odours are far less likely to spread from one flat to another.

Energy savings and heat recovery

Heat recovery ventilation captures a large share of the heat from extracted air and helps reduce the cost of heating incoming fresh air.

A reliable system and easier management

A system that has been properly built, measured, and documented is easier for the housing association to maintain, monitor, and adjust later on.

Property value and the reputation of the housing association

Reconstructing the ventilation system in an apartment building helps reduce repeated complaints and improves the overall quality of the living environment.

Why trust Aero Grupp with apartment building ventilation installation?

Ventilation installation is not something that should be awarded to the cheapest bidder, because the investment is substantial either way and the housing association’s responsibilities are long term.

What matters here is experience, well-developed working practices, and the ability to carry out the work in a way that causes as little disruption as possible to residents’ everyday lives.

Aero Grupp has been providing ventilation services across Estonia for 17 years, with offices in both Tallinn and Tartu.

Over 17 years of experience and 80+ reconstructed buildings

We have more than 12 years of experience specifically in ventilation works for renovated apartment buildings. We have completed ventilation installation projects in more than 80 apartment buildings under renovation across Estonia.

The capability to carry out surveys and system assessments

Good decisions start with a thorough project brief. We have carried out surveys and system assessment work in more than 650 apartment buildings across Estonia.

We are part of the EVHA professional network

EVHA brings together specialists in ventilation hygiene and indoor air quality across Europe and helps us stay up to date with best practices in ventilation hygiene.

We carry liability insurance

If unexpected damage should occur during the work, the housing association will not be left to deal with the issue alone. It is part of a professional approach to risk management and responsible project delivery.

What is most important to us in the ventilation installation process?

Ventilation works in apartment buildings are always a team effort, where communication with residents and sticking to the agreed working arrangements matter just as much as the technical side of the job.

What matters in apartment building ventilation installation

Thorough assessment and a clear project brief

We start by understanding the existing situation. Where needed, we carry out video inspections and system assessments to establish where the ducts and shafts are actually located and what condition they are in.

A clear plan and proper coordination

We turn the design and technical solution into a practical work plan. We agree how the work will move through flats and corridors so that disruption to residents is kept to a minimum.

Clear and respectful communication with residents

This is the stage that many housing associations worry about most. We agree a clear execution plan with the association and keep communication straightforward. Residents know in advance when we will arrive and how long the work in their flat will take.

Clean and considerate workmanship

We keep the work area tidy, protect against dust, work carefully, and clean up after ourselves. Installing a ventilation system does not have to mean that the stairwell looks like a building site for weeks.

Measurement, commissioning, and handover

Once the system is complete, we document the results so that the system can later be checked and, if needed, the correct settings can be restored.

Answers to some common questions that come up when apartment building ventilation installation is being planned

How is ventilation reconstruction typically carried out during the renovation of an apartment building?

In most cases, a central mechanical ventilation system is installed, with supply and extract ducts routed into the flats and the air handling unit placed in the attic, on the roof, or in a technical room. In many cases, ductwork can be concealed beneath the façade insulation so that the external appearance of the building remains neat.

Does every flat need to be accessible for ventilation installation works?

In many cases, yes, because the installation of terminal units and the air distribution setup inside the flats require access to the living spaces. If a flat owner refuses access, the housing association may in certain situations have the right to require it if the work is necessary for the building’s shared systems.

Why do some flats experience draughts after a new ventilation system has been installed?

This is usually caused by airflow balancing, the positioning of terminal units, or system settings rather than by the ventilation system itself. It can be resolved through proper measurement and adjustment so that air distribution is even and discomfort is reduced.

How much dust and disruption do ventilation works usually cause in an apartment building?

With proper planning and site management, dust and disruption can be kept to a minimum by using dust protection and covering work areas. It is also important that the site is cleaned after the works so that neither the stairwell nor the flat is left looking like a building site.

How long does apartment building ventilation renovation usually take?

The duration depends on the size of the building, the selected solution, and whether the shafts and ducts require additional work. The exact schedule becomes clear after the survey and work plan have been completed.

What has the biggest impact on the cost of apartment building ventilation installation?

The main cost factors include the number of flats and risers, the condition of the shafts and ventilation ducts, the chosen technical solution, and how the works are phased. The exact cost can only be confirmed after a site inspection and review of the project data.
