Why choose Avenir Renovations?
The parts of the home to insulate as a priority in the canton of Basel-City
A poorly insulated home increases heating bills and leaves rooms cold all winter. In a canton where 75% of buildings date from before 1961, targeted insulation work in Basel primarily focuses on the most heat-loss-prone walls. Comfort also improves in summer.
The facade, the first area of heat loss to address
Exterior walls form the largest surface of the envelope, and their heat loss weighs heavily on the facades of older buildings. Two techniques can be used to address this. Peripheral insulation, or external insulation, is fixed to the facade and then receives a render or cladding; internal insulation is installed from within the rooms. The first preserves the living space, while the second keeps the facade's appearance intact. The insulators used, from rock wool to natural insulators, are described on our dedicated insulation work page, along with their applications depending on the type of support.
The attic, whether lost or converted, should not be overlooked
Under the roof, the room becomes a sauna in summer and cools down as soon as the heating is turned down, a common sign of poorly insulated roofs. This scenario often indicates poorly insulated attics, through which a large part of the heat escapes. Lost attics can be treated by blowing insulation or by laying rolls on the floor.
Converted attics require a more meticulous installation under the slopes, which preserves the ceiling height as much as possible. Our craftsmen choose the thickness and the insulator according to the framework and the use of the room. A damaged or damp framework requires specialized advice before any installation, otherwise the insulation will degrade.
Ground floors, often forgotten
Before renovating your floors, consider the ground floor, especially above an unheated basement or garage, as this area also affects the comfort of adjacent rooms. This discreet area cools the feet and the rooms on the ground floor. Our Project Manager checks access from below and the condition of the slab before proposing a technique.
Depending on the configuration, several solutions are available to you:
- panels fixed to the ceiling of the basement,
- sprayed insulation under the slab,
- insulation laid on the slab during a floor renovation,
- loose insulation between the joists of a wooden floor.
The humidity in the basement must be controlled before any installation, or it may damage the ceilings and reduce the energy performance of the home. An excessively high humidity level degrades the insulation installed on the ceiling and reduces its long-term performance, hence the importance of a prior check by our Project Manager.
How does an insulation project proceed in the canton of Basel-City?
On a winter evening, the living room remains cold despite the heating being turned up to maximum, and the last bill has increased again. With Avenir Renovations Basel, our company then follows a precise order, from diagnosis to completion, and each document remains accessible in your client area.
Avenir Renovations, a single point of contact close to Basel
At Avenir Renovations, our company commits to calling you back within 48 hours after your request for a quote, including for a project in Basel. This short timeframe allows you to plan your work calmly before winter. Our Project Manager remains your sole contact from the study to acceptance.
A standard rate received after a simple form does not resemble a proposal established by a company after a visit to your home. At Avenir Renovations Basel, we provide a free and personalized quote, even when the visit requires travel from our agency. It itemizes each aspect based on the diagnosis, with the insulation and technique chosen for your property. You thus know precisely what each item covers before signing. The visit also allows us to assess on-site access to the project and the actual condition of existing supports.
Poorly installed insulation, with open joints or a discontinuous vapor barrier, loses part of its effectiveness and can promote condensation. Our qualified craftsmen work according to Swiss standards and pay attention to these execution details. These details are crucial at the time of installation and become invisible once the finishing touches are completed, hence the importance of control.
The materials used are chosen for their compatibility with the existing substrate, especially during the renovation of old walls. For certain services, such as painting or carpentry, a warranty covers the installation and materials. For a protected building or an atypical construction, the advice of a specialized professional is necessary before making a decision.
What is the cost of insulation work in Basel?
The cost of your insulation is calculated per square meter and varies depending on the part of the home being treated and the chosen technique. Four factors influence the estimate provided by our Project Manager: the area to be insulated, the type of insulation selected, the accessibility of the site, and the condition of the floors or support. A facade that requires scaffolding or walls that need to be renovated before installation require more preparation.
Interior insulation also involves the removal and reinstallation of certain elements, such as radiators. Grants from the Cantonal Building Program can reduce the amount you have to pay, depending on the insulated elements.
To start your insulation work in Basel, simply send your request for a quote to our company, which will organize the visit. At Avenir Renovations, we then estimate each item based on your actual surfaces and the conclusions of the diagnosis.

Should you always insulate from the outside for good performance?
No, external insulation is not systematic. It treats a facade continuously, but its relevance depends on the substrate, the configuration of the housing, and local regulations. In Basel-City, any modification to the appearance of a facade must be announced and authorized. A protected building or one located in a classified area may require a standard building permit.
In condominiums, the agreement of the co-owners adds to these steps. Internal insulation is suitable for a facade to be preserved, at the cost of a slight loss of living space. In other cases, insulating lost attics, roofs, or the ground floor targets the main heat losses with a lighter construction. The thermal diagnosis carried out by our Project Manager indicates which combination is suitable for your property.
