Recent reforms to the DPE and restrictions on energy-intensive housing have changed the way the French approach improving their homes. Insulation, ventilation, and lighting are no longer just about personal comfort: they determine the value of the property and its regulatory compliance. At the same time, a movement towards repairable and energy-efficient equipment is redefining what it means to “improve one’s home” on a daily basis.
Repairability and sobriety: the true lever for sustainable comfort
Accumulating connected devices or multiplying decorative purchases does not guarantee a more pleasant living environment. For several years, ADEME has documented a growing interest among households in sustainability and repairability as a long-term comfort lever, rather than the rapid replacement of recent devices.

In practical terms, this translates into choices that are increasingly found in the home advice from Ma Maison Info: favoring refurbished appliances with available spare parts, opting for mechanical systems (natural ventilation, manual blinds) rather than electronic ones, or choosing raw materials that are easy to maintain.
This approach changes the perspective. Before buying a new item for the kitchen or living room, the question becomes: will this equipment be repairable in five years, and does it consume less than the one it replaces?

- A vacuum cleaner with individually replaceable motor and filters will last much longer than a sealed model, even a high-end one.
- A solid wood piece of furniture can be sanded and repainted, whereas a melamine particle board piece ends up in the landfill at the first chip.
- A well-maintained single-flow ventilation system ensures proper air renewal without the complexity (or maintenance cost) of a poorly sized double-flow system.
The repairability of equipment determines its actual lifespan, not its technical specifications. This criterion should take precedence over price or design in any home purchase decision.
Energy performance of housing: what the DPE changes in daily work
Since the reform of the DPE and the measures on energy-intensive housing implemented between 2021 and 2025, a simple window change or the addition of an exterior blind is no longer trivial. These interventions directly influence the energy class of the property, which in turn determines the right to rent it out or its attractiveness for resale.
Insulating, ventilating, and lighting one’s home is now as much about compliance as it is about comfort. Applying an insulating film to a single-glazed window, installing a properly sized ventilation grille, or replacing halogen lighting with LEDs: each of these actions, taken individually, seems modest. But their cumulative effect can shift a DPE from one letter to another.
Prioritizing work according to its impact on the DPE
Not all improvements are equal. Insulating attics or walls from the inside has a measurable effect on the energy rating. In contrast, changing a countertop or repainting a wall, as pleasant as it may be, does not change anything in this regard.
Field feedback varies on this point: some craftsmen promote aesthetic work by presenting it as “enhancing” for the property, without mentioning that only thermal aspects weigh in the diagnosis. Before starting improvement work, consulting the existing DPE allows one to know where to focus the budget for a real effect.
Regular maintenance: actions that prevent heavy work
The majority of damage in a home comes from a lack of regular maintenance, not from a construction defect. A bathroom seal left porous for two years eventually causes an infiltration that damages the wall. A hood filter that is never cleaned forces the motor and halves its lifespan.
A targeted maintenance routine each month often replaces an expensive repair every three years. The logic is the same as that of repairability: acting proactively costs less and preserves daily comfort.
- Descaling the showerhead and faucets every two to three months maintains flow and protects seals.
- Checking the condition of window seals at each change of season prevents drafts and thermal losses.
- Vacuuming the ventilation grilles (kitchen, bathroom) prevents dust accumulation that reduces airflow and degrades indoor air quality.
- Bleeding radiators before the heating season ensures even heat distribution in each room.
Accessible DIY or professional intervention
For storage, decoration, or replacing a kitchen accessory, DIY is sufficient in most cases. The available data does not allow for a universal threshold to be set, but a simple guideline exists: as soon as a job involves electricity (beyond replacing a socket or switch), embedded plumbing, or load-bearing structure, calling in a qualified professional is the only reasonable option.
Confusing home hacks with technical interventions remains the leading cause of declared claims in home insurance for water damage related to non-compliant work.
Interior design: think circulation before decoration
Many articles on home improvement start with wall color or furniture choice. However, circulation within rooms determines real daily comfort much more than the color of a cushion.
A living room where one has to navigate around the coffee table to access the kitchen, an entryway cluttered with shoes without dedicated storage, a hallway too narrow to pass someone: these daily irritants are rarely resolved with a decorative purchase. They require rethinking the layout of existing furniture.
Clearing the main passageways between the entryway, kitchen, and living room transforms the perception of space without any cost. This is the first action to test before considering new furniture or partitioning work.
Some rooms benefit from being under-furnished. A living room with a sofa, a coffee table, and closed storage will be more pleasant to live in than a living room saturated with furniture, even if each piece individually “looks good.” The empty space on the floor actively contributes to comfort, especially in small homes.
Improving a home on a daily basis relies on concrete trade-offs: repairability of equipment, real impact on energy performance, regular preventive maintenance, and smooth circulation between rooms. These four axes, often less photogenic than a freshly painted trendy wall, nonetheless determine the quality of life over time.
