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

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

Rotten Window Repair does not manufacture glass. Instead, we partner with trusted American window glass suppliers who have proven themselves to our customers through quality and reliability.

For over 9 years, we have been selecting materials with great care and working with Cardinal Glass Industries, a brand that our customers consider to be the best in the United States. Cardinal is a leading manufacturer of high-performance glass for windows and doors, whose products are used by the country’s largest window brands. Their glass undergoes rigorous testing, meets environmental standards (EPD), and is constantly being improved.
