Eliminating Window Condensation, Leaks, and Sill Rot

Persistent moisture on window glass or water leaking around sills often leads to hidden drywall mold, peeling exterior paint, and structural framing deterioration. When insulated glazing units fail, humid air infiltrates between glass layers, producing permanent fogging and mold spores along internal sash tracks. Veltrix Windows diagnoses moisture intrusion sources, replaces deteriorated timber with rot-resistant composites, and installs airtight flashing systems to keep your home healthy and dry.
