Correctly sealing garage doors

Valuable tips and tricks for dry and securely parked vehicles and objects

Tightly sealed garage doors protect against vermin, surface water and splash water. However, there are a few important points to bear in mind when subsequently sealing the doors to ensure that the vehicles and objects parked in the garage do not end up with mould or corrosion damage.

Options for retrofitting seals to garage doors

If the garage door does not close properly

Technical defects in garage doors are usually obvious because the doors do not close properly or can only be moved slowly. But even barely noticeable details, such as a small gap to the floor, can cause major problems. This is where vermin and surface water can get into the garage.

Ground sills against surface water ingress

Rainwater run-off or melting snow can get into the garage, especially on sloping garage driveways. Retrofittable rubber profiles made of robust EPDM provide a quick remedy here. They are installed as thresholds on the floor, where they protect against water ingress even when the doors are open, but are often perceived as a tripping hazard or unpleasant resistance when driving over them.

All-round rubber lips against vermin and splash water

To prevent the ingress of vermin or splash water in particular, you can attach circumferential rubber lips or brush seals to the garage door or door frame, which effectively seal the door opening. However, if the humidity in the garage is already high before sealing, you should be careful. This is because sealing significantly reduces the necessary ventilation cross-section.

Heat loss is hardly prevented by sealed garage doors

Sealing your garage door prevents cold air from entering in winter. However, the gap between the door and frame is generally not so large that the garage cools down in this way. The wall surfaces or the door leaf are more decisive for heat loss. If these are insulated (even retrospectively), the garage will be significantly less hot in summer and less cold in winter.

Essential in the garage: low humidity and good air circulation

High humidity due to wet vehicles

The most common cause of high humidity in garages are vehicles that are parked in rain or snow, which dry out slowly, especially in the cold season. This is due to the low temperatures, which slow down the natural evaporation process, but often also to inadequate air circulation.

Well-sealed garage doors require good ventilation

If garage doors are sealed with rubber lips, for example, it is essential to ensure sufficient ventilation - for example by using suitable ventilation openings in the door or in wicket doors. If this is not done, there is an increased risk of mould or corrosion damage to vehicles and all objects stored in the garage.

Natural ventilation instead of heating or dehumidification devices

There are many ways to combat high humidity in the garage: you can heat the air in the room with heaters to increase the evaporation rate or use dehumidifiers. However, it is more ecological and economical than electrical devices to supply the garage with sufficient natural fresh air.

Well-ventilated, dry parking spaces - also in collective garages

The right measure for tightness and permeability

As in single or double garages, the right balance between air permeability and tightness is also essential in collective garages. For example, a rubber lip on the underside of a roller shutter door can prevent surface water from entering the underground car park, while at the same time the door ensures the ventilation cross-section required for natural ventilation and smoke extraction in the garage. If this is guaranteed, there is no need for expensive mechanical ventilation systems.

Parking boxes in collective garages: plenty of privacy and good air circulation

As a leading German manufacturer of garage doors, Käuferle also offers partition wall systems as well as sliding, swing or tilting doors that are suitable for separating parking boxes in underground car parks. With perforated metal panels, these create a high degree of opacity (and privacy) without neglecting the necessary ventilation cross-sections.

Frequently asked questions about sealing garage doors

Here you will find answers to frequently asked questions about sealing garage doors:

Does Käuferle offer garage doors that match the design of my listed old building and still fulfil the required ventilation cross-sections?

Our doors are always customised. Special installation situations and the consideration of qualified ventilation concepts are therefore part of our everyday work.
Our garage door from the 1980s is warped and has large gaps all round. Can this door also be sealed?

In principle, yes. However, in view of the advanced age and damage, a new door could be more economical in the long term. We will be happy to provide you with a non-binding offer.
Can we prevent water from entering our double garage by subsequently sealing the garage door?

Moisture usually enters the garage through wet vehicles. However, if surface water penetrates, a new/additional floor seal may be advisable.
As a homeowners' association, we are planning lockable individual parking spaces in our underground car park. What should we bear in mind?

Partition walls and doors should not restrict the air circulation too much so that water brought into the garage can evaporate easily and the humidity does not become too high.
