Sustainably upgrading old windows: a cost-efficient solution

Many old windows found in households and buildings are past their best - at least at first glance. However, the problem often lies less in the substance of the window itself, but rather in signs of wear and tear such as defective seals or worn fittings. The main consequences of these defects are draughts and energy losses, which have a noticeable impact on heating costs. An efficient and sustainable solution is the professional refurbishment of such windows, which is considerably cheaper than a complete replacement.

Optimization instead of replacement: How to turn old into tight again

A prime example of the modernization of old windows can be seen in a 40-year-old model. Defective seals, which have often become unusable due to paint or natural wear and tear, lead to enormous heat loss. Added to this are stiff and worn fittings that make daily use difficult. The solution lies in a targeted overhaul: new seals with high resilience and modernized fittings not only ensure perfect functionality, but also close the window airtight again. Simple tests, such as the paper strip test, can be used to check the tightness after the overhaul. The result: savings of up to 60% on heating costs.

Sustainability and efficiency with Service Friends

Refurbishing old windows with Service Friends is not only a cost-effective alternative to new windows - it also protects the environment. Energy-intensive components such as the frame profile or glazing are retained, which saves resources. At the same time, there is no need for the costly construction work that would be required when replacing a window. At a cost of around 200 to 400 euros per window, this method is a fraction of the cost of a complete replacement. In addition, the investment is quickly amortized through the reduction in energy losses - scientifically proven by expert reports, for example from the Technical University of Stuttgart.

Conclusion: Sustainable window upgrade with added value

Upgrading old windows is a simple and effective way to reduce heating costs and extend the service life of windows. Replacing seals and fittings on site not only increases comfort, but also makes a valuable contribution to sustainability. This solution combines cost efficiency with environmental awareness and shows that old windows have more potential than you might think.
