Joinery installation work in Marche-en-Famenne

Sliding glass doors: opening your home to Famenne

A radical transformation of space

One of the most significant transformations during a renovation in Marche-en-Famenne is the installation of a sliding glass door. Removing a blind wall to replace it with a large sliding opening radically changes the perception of space and brings valuable light during the winter months.

Technical installation and safety

These heavy carpentry elements require particular expertise. The weight of the glazing and the dimensions of the profiles require installation on perfectly level supports. Our sliding glass doors are equipped with ultra-smooth rolling systems, allowing the movement of panels weighing several hundred kilograms with a simple gesture. We also ensure safety with anti-burglary hardware, essential for your peace of mind in Aye or Hargimont.

Roof Joinery: Bringing Light to the Attic

The Velux to Transform Your Attic

The fit-out of an attic in Marche-en-Famenne often involves the installation of a Velux roof window. This is the most effective solution to transform a dark storage space into a bright bedroom or a pleasant office.

A Careful Installation for a Watertight Roof

The installation on the roof is a delicate operation that directly affects the watertightness of your covering, whether it is slate or tiles. We carry out the necessary openings in the framework and install the sealing connections with care. A well-installed Velux ensures optimized natural ventilation and solar gain that naturally warms the room in mid-season. We also offer motorized external roller shutters for total darkness and protection against hail.

Avenir Rénovations Installation Technique: The Rigor of Detail

A Precise Installation Protocol

In Marche, our installers do not just assemble frames. Each intervention follows a precise protocol. A joinery that does not fit perfectly is a joinery that will wear out prematurely and lose thermal performance.

Interior Finishes and Site Cleanup

After our visit, we carry out the interior finishes — reveals and sills — and ensure the removal of debris and old materials. A final adjustment of each handle, a cleaning of the windows, and your house changes dimension. No residual dust to manage: we leave the site clean.

Taxation and Grants: The 6% VAT at Your Service

An Immediate Tax Advantage

An immediate tax advantage: for any building over ten years old, the VAT is reduced to 6% on both materials and installation labor. Replacing exterior joinery is an investment that pays off immediately — this reduced rate of 6% represents a direct saving from the first invoice.

Walloon Grants and Return on Investment

In Wallonia, grants related to the insulation of glazed walls are substantial, especially if you conduct a prior housing audit. Our specialists explain these financial mechanisms to make your project as accessible as possible. By combining these aids, the return on investment through energy savings is often achieved in less than eight years.

Common Issues and Our Solutions

Swollen or Deformed Frames That Cannot Close Properly

In houses built before the 1990s in Marche-en-Famenne and surrounding villages, it is common to encounter low-quality wooden or PVC frames that have warped due to humidity and freeze-thaw cycles. A frame that is difficult to close is no longer thermally watertight, and forcing the hardware further aggravates the deformation. The solution is a complete replacement with a properly sized rigid profile, installed on a sound and level support.

Thermal Bridge on Poorly Framed Bay Returns

Even a high-performance new frame is not sufficient if the bay's frame — the side surface between the frame and the interior wall — is not insulated. This thermal bridge generates condensation in winter, promotes mold, and negates some of the benefits of the new glazing. At Avenir Rénovations, every installation includes careful treatment of bay returns with suitable insulation and a clean plaster finish.

Condensation Between Panes on Aging Double Glazing

When a milky film or droplets appear between the two panes, the peripheral seal of the insulating glazing is broken: the argon or krypton has escaped and moisture has entered the casing. This defect cannot be repaired — the glazing must be replaced. The Avenir Rénovations team assesses whether only the glazing can be changed in the existing profile, or if the entire frame needs to be renewed for performance or overall watertightness.

Frequently Asked Questions

Is it better to choose PVC or aluminum for the frames of my house in Marche-en-Famenne?

PVC offers the best value for money and the best pure thermal performance thanks to its multiple chambers. Aluminum is more suitable for large glazed surfaces — sliding doors, wide facade windows — as its rigidity allows for thinner profiles without losing stability. For homes in the center of Marche or in villages where charm is important, wood remains an option, provided you are willing to accept regular maintenance.

How long does it take to install a window or a frame?

The installation of a standard window generally takes half a day per opening, including the removal of the old frame, preparation of the sill, and interior finishes. For a complete replacement of all windows in a house, the work usually takes two to three days. Our Marche artisans provide you with a precise schedule before the start of the work.

Does the installation of new frames qualify for grants in Wallonia?

Yes. In Wallonia, grants for energy renovation are available for replacing low-performance glazing with high-efficiency double or triple glazing, especially if a prior housing audit has been conducted. These aids can be combined with the 6% rate advantage applicable to homes over ten years old. Our specialists guide you through these processes to optimize the financing of your project.

Does installing a Velux require significant work on the framework?

Installing a roof window involves creating a frame in the structure to outline the opening, as well as installing specific sealing connections around the frame. These interventions are managed by our teams and do not weaken the structure if done correctly. The operation directly affects the waterproofing of your roof, which is why it should not be entrusted to just anyone.
