Our Specialized Wooden Joinery and Window Repair Services

Repair and Replacement of Antique and Custom Hardware

We are experts in repairing and reproducing wooden window hardware, including traditional systems, decorative espagnolettes, and multi-point locks. We source original parts or create faithful replicas, which is crucial for listed buildings or historic façades in Brussels. We ensure your heritage is maintained.

Wood Treatment and Replacement of Degraded Sections

Rot (dry or wet) is wood's primary enemy. We surgically remove damaged wood and replace it with new, treated, and compatible wood grafts (often durable hardwoods like Meranti or Iroko), thus ensuring the long-term stability and aesthetic continuity of the frame.

Thermal and Acoustic Insulation Upgrading

An older wooden frame can be brought up to modern EPB requirements. We improve airtightness by installing high-performance gaskets and replace single glazing with high-efficiency double glazing (HR++), all while carefully preserving the look of the original glazing beads.

Frequently Asked Questions

We’ve taken the time to provide detailed answers to common inquiries, ensuring you have the information you need at your fingertips.

ALL FAQs
Is a warped wooden window frame always irreparable?

No, not necessarily. Warping is often caused by moisture and poor drainage. Our joiners can frequently realign the profile through specialized clamping or planing techniques, followed by protective treatments to stabilize the wood. Our goal is always to save the existing frame and avoid the high cost of a full replacement, provided the warp is not structural.

It depends on the scale. Replacing specific antique hardware can be expensive if the part needs to be custom-fabricated. However, extensive rot treatment over a large area, which includes stripping down the frame and grafting new wood, is often the most time-consuming and therefore the most costly intervention. We provide a detailed, written quote that transparently segments labor and material costs.

Yes, this is our core specialty. It is the most common and cost-effective solution for improving the EPB performance of Brussels properties. It involves carefully widening the rebate (the groove holding the glass) and installing slim, high-performance double-glazing (HR++), which is compatible with the weight and structure of the existing wooden frame.

We offer a specific, written warranty on the curative treatment and the new wood grafts used. This warranty covers the recurrence of rot in the treated zone, provided that the exterior finish (paint or stain) is properly maintained by the homeowner to protect the wood from moisture ingress.

Which areas of Brussels do you serve for wooden joinery repair?

We cover the entire Brussels-Capital Region. Our specialized expertise is particularly sought after in areas with a high concentration of heritage and older buildings, such as Saint-Gilles, Ixelles, Schaerbeek, and the protected zones near the city center, where the conservation of original wooden windows is essential.
