Windows drafty, foggy, or leaking — Haarlem, North Holland
Drafty, foggy, or leaking windows signal failed seals, deteriorated weatherstripping, or frames past their useful life. Single-pane windows and double-pane units over 15–20 years old are the most common culprits. Foggy glass between double-pane panels means the seal has broken and argon gas has escaped — the unit must be replaced, not repaired. Replacing windows ($300–$800 per window installed for vinyl, $800–$1,500+ for wood or fiberglass) typically pays back in energy savings of 10–25% on heating/cooling bills (ENERGY STAR estimates $101–$583 annually for a full-home replacement). Window installation takes 30–60 minutes per unit for a retrofit (insert) install, or 2–4 hours for a full-frame replacement that includes modifying the rough opening.
Why this is common in Haarlem
The 17th-century and older stock features original timber beams, staircases, and panelling needing expert heritage restoration, and pile-foundation settlement causes sloping floors and sticking doors that drive recurring corrective work.
