Choose a path
Three ways to talk about the same home.
Why one is highlighted
The recommended upgrade gives the clearest energy-label improvement while keeping the cost and disruption realistic before a sale.
Lowest upfront spend
Start small
Do the least expensive high-impact window work before listing. It improves the story, but the model stays at energy label D.

Best balance for a sale
Recommended upgrade
Replace the window groups that do the most work for comfort and energy use. This gives buyers a clear path toward C without presenting the home as a major renovation project.

Most energy saved
Bigger renovation
Treat the home as a longer-term upgrade project and include the broadest set of positive measures. It saves the most energy, but the cost and disruption make it better after the sale.
