10-year warranty on wood work
Many homeowners favor wooden windows for their timeless appeal and environmental benefits. As a natural, renewable resource, wood is free from toxic emissions and stands out for its sustainability and organic charm.
What problems arise with wooden windows?
Rot and mold: due to moisture, poor ventilation, or old paint
Cracks and drying out: due to temperature and humidity fluctuations
Deformation: wood can warp if used incorrectly
Loss of airtightness: due to worn seals or damage to the frame
Reduced thermal insulation: due to damage to the double-glazed window or frame
How do we repair wooden windows?
- Diagnostics: we carefully inspect the window and identify all defects
- Damage removal: we remove rot, mold, and old paint
- Structure restoration: we use professional compounds to strengthen the wood
- Replacement of elements: if necessary, we replace parts of the frame, sash, and seals
- Finishing: we sand, prime, and paint — the window looks like new
- Sealing and insulation: we restore heat and sound insulation
