Changing floors in Martigny: A comprehensive guide for homeowners

2 °C. These conditions, coupled with an average of 50 frost days per year, impose specific requirements on the choice and durability of your flooring.

Undertaking these works is often the ideal opportunity to improve overall thermal insulation, thus reducing energy needs in an area where heating is required for a long period.

Beyond the aesthetic aspect, the renewal of floors is a strategic decision to adapt your housing to the evolution of your needs. Changing the covering allows not only to modernize the interior but also to check the state of the support.

In Martigny, where indoor life is marked by these harsh winters, investing in high-performance materials contributes directly to the longevity of your building and your daily well-being by minimizing heat losses through the floor surfaces.

The success of a floor change depends greatly on the technical compatibility between the chosen material and the existing substrate. Whether you opt for parquet, tiles, or synthetic floors, the preparation of the screed remains a decisive step to avoid any future pathology.

In the context of Martigny, if your home is equipped with underfloor heating, it is imperative to select coverings with low thermal resistance to guarantee good conductivity and thus optimize the efficiency of your heating installation.

Furthermore, the choice of range and materials influences not only the aesthetics but also the wear resistance, a key factor in high-traffic areas.

It is also necessary to take into account acoustic requirements, especially if you reside in a condominium building, where the condominium regulations often impose strict standards regarding impact noise insulation.

By accurately evaluating the nature of your substrate, whether it is a raw slab or an existing covering to be covered, you will avoid additional costs related to inadequate surface preparation or unsuitable covering thickness.

Martigny has a diverse housing stock. For buildings constructed before 1990, increased vigilance is recommended when removing old floors, particularly due to the possible presence of hazardous materials such as asbestos in adhesives or old vinyl tiles.

It is therefore essential to carry out a preliminary diagnosis before any major renovation project on these structures. Knowledge of the construction period allows for anticipating the nature of the load-bearing structures and embedded networks that could be damaged during the works.

Older buildings also present challenges in terms of insulation and substrate leveling. In the case of a renovation, leveling on wooden floors or heterogeneous structures requires specific expertise to guarantee perfect flatness, a sine qua non condition for laying modern coverings.

In addition, heating or electrical distribution networks may have been modified over the decades; a precise mapping of these elements is advised before starting demolition work or fixing new floors to secure the site in the long term.

Martigny is actively committed to preserving its architectural identity. The city is currently in the process of surveying its built heritage.

It is essential to inquire about any constraints related to your geographical location, especially if your building is located in an ISOS perimeter or an area listed for its concentration of historical buildings.

Approval of the PAZ (Zoning Plan) and the RCCZ (Construction and Zoning Regulation) is being deployed by 2025 to better protect these sectors.

Before undertaking work that could significantly alter the structure or appearance of a protected building, contact the municipal urban planning department.

Although changing interior floor coverings does not systematically require a building permit, any intervention affecting the structure, floor levels, or insulation must be clarified.

A proactive check will save you administrative complications and ensure that your work complies with future municipal orientations regarding territory enhancement.

Regarding local taxation, property owners in Martigny are subject to the current municipal scales.1.

It is important to note that the floor change itself does not constitute a charge directly deductible as routine maintenance, unless the works aim at a complete restoration after a period of deterioration or are related to validated energy saving measures.

Always check with your fiduciary or the cantonal tax authorities to confirm the eligibility of your works in your declaration.

There are currently no specific grants provided by the municipality of Martigny for simple floor covering replacement.

However, if your work includes high-performance thermal insulation of the floor, it may be appropriate to check if federal or cantonal subsidies exist for the energy improvement of the building envelope.

In any case, make sure to formalize your requests and obtain the necessary agreements before starting any work, as aid generally cannot be granted retroactively once the works are completed.

Planning your floor work should ideally take into account local climatic conditions, particularly the 50 annual frost days recorded in Martigny.

Although the work is mostly carried out indoors, periods of extreme cold can influence the drying times of certain mortars or adhesives if humidity and ambient temperature are not strictly controlled.

An installation during a period of temperate weather greatly facilitates the work and ensures better stability of the new materials.

The typical flow starts with a diagnosis and quote phase, followed by the preparation of the substrate. This step includes removing the old covering, managing potential waste, and leveling to obtain a flat surface. Then comes the installation of the final covering, followed by finishes (skirting boards, thresholds).

The total duration will depend on the surface area, the nature of the substrate, and the material chosen. It is advisable to allow for a margin of maneuver, especially for the drying of the screed, so as not to rush the laying of the final covering, at the risk of seeing cracks appear or the tiles or boards detaching.

To avoid disappointment, start by checking the condition of your substrate, as it often determines the final cost more than the covering itself.

Make sure you have clarified the sound insulation requirements if you are in a condominium, to avoid having to replace a floor that does not comply with the building regulations. Never neglect the compatibility of the covering with your underfloor heating system before signing a contract.

Before requesting quotes, ensure your project is precise.

The basic checklist includes : checking if asbestos is present in the old covering (pre-1990 building), validating the total thickness available so as not to hinder the opening of doors, confirming the material's compatibility with damp rooms, and obtaining a detailed quote including substrate preparation.

Do not choose a craftsman based solely on price, but check local references. Finally, ensure all site access is clear and that scheduling includes a real drying period.
