Window replacement in rental apartments - What you should know

As a tenant, the question often arises as to whether and how a window replacement is possible. First of all, it is crucial that the tenant and landlord make clear agreements in advance. The landlord is usually responsible for the maintenance of the property. They therefore bear the costs of replacing old or defective windows. However, tenants should inform the landlord of any necessary repairs in good time. Replacing windows can increase living comfort and reduce energy costs, which is also in the landlord's interest.

Healthy living through window replacement

New windows make a house more energy-efficient and healthier. High-quality aluminum windows from heroal let in fewer draughts and prevent moisture. This reduces the risk of mold. The thermal insulation ensures even temperatures in the room and avoids cold zones at the windows. In addition, innovative ventilation solutions, such as the heroal window rebate ventilator, support a continuous exchange of air and improve the air quality in the house.
