In Aalst and its sub-municipalities there are many post-war estate houses whose first-generation double glazing and aluminium sliding windows are due for replacement. Roller shutters from the 1970s and 1980s get stuck, draught strips are worn, and U-values no longer meet current energy standards. Renovata connects you with joiners and window fitters from your region.
Aalst has a compact city centre with terraced houses, but most homes are in the surrounding neighbourhoods and sub-municipalities: Erembodegem, Nieuwerkerken, Moorsel, Hofstade, Herdersem. There, post-war and 1970s-1980s estate houses dominate — semi-detached or detached, with a garden, garage and driveway.
In this generation of homes, the basic installations (electrics, gas central heating, plumbing) are reaching renovation age. What was new 30 to 40 years ago now needs replacing or upgrading to meet current standards and consumption levels.
Unlike Ghent, there is usually more space around the house in Aalst: flat roofs on garages and sheds, gardens that need maintenance, and outside walls that are fully visible and can be tackled without heritage rules.
The first generation of double glazing in estate houses has a U-value of around 2.8 W/m²K — more than three times worse than today's HR++ or triple glazing. Replacing it gives a noticeable gain in warmth and sound insulation and qualifies for Flemish renovation grants from a U-value of 1.0 or lower.
Old surface-mounted roller shutters with worn straps, blocked slats or broken belts are often tackled together with the windows. The new generation is electrically operated, integrated into the window box, and works by remote control or app. For the same opening, that is often half a day's work.
Single-glazed aluminium sliding doors from the building period 30 to 40 years ago are cold bridges. Modern lift-and-slide systems in thermally broken aluminium or PVC offer similar views with a much better U-value and smoother operation — important for large openings to the garden.
Detached and semi-detached homes usually have three to four outside doors: front door, back door to the garden, side door from the garage and sometimes a door at the utility room. They are all exposed to wind and weather, and quite often one no longer closes while the others can last for years — ask for a quote per door, not as a package.
Old up-and-over or side-hinged doors take up a lot of space inside and outside. A sectional door slides under the ceiling and keeps the whole driveway free — important with a short driveway up to the building line, as in many Aalst estates. Electric operation, insulation and burglary protection are standard today.

For most post-war homes, PVC offers the best value for money: good insulation, little maintenance, affordable. Aluminium wins for large sizes (sliding door, wide window sections). Wood is best kept for homes where the look calls for it — rare in typical Aalst estates.
Via Mijn VerbouwPremie you receive an amount per m² of glass area, provided the U-value is at most 1.0 W/m²K. The contractor supplies the certificate of conformity. Also check whether you qualify for the ventilation grant at the same time — with new airtight windows it is often needed.
Yes, in almost all cases. New surface-mounted roller shutters hang on the outside of the facade or are mounted at the top of the existing frame, without touching the windows themselves. This is a smaller project, usually half a day to a full day per side of the house.
With a clean removal, the damage is usually limited to a strip of 2 to 3 cm around the new frame. Some joiners work with a plasterer and include this in the quote; others deliver ready-fitted and leave the finishing to you. Ask about this clearly in advance.
For 10 to 15 window sections, expect 3 to 5 working days on site, spread over one or two weeks. The delivery time for the windows themselves is currently 8 to 12 weeks after the final order — so plan your project at least three months in advance.
