Hampshire's Condensation Repair Specialists
Condensation between glass panes is a common problem across Hampshire, particularly in coastal areas like Portsmouth and Southampton where humidity levels are higher. This occurs when the seal around double or triple glazed units fails, allowing moisture to penetrate between the glass layers.
Hampshire's maritime climate, from the Solent waters to the chalk downs, creates conditions that can accelerate seal failure. Our local expertise across Southampton, Bournemouth, Winchester and surrounding areas means we understand these environmental factors and provide solutions specifically designed for Hampshire's unique conditions.

Condensation Repair Across Hampshire
Frequently Asked Questions
Most misted or condensation-affected sealed units can be replaced within 1-2 hours per window. We measure on the first visit and typically return within 5-7 working days with your new units, which are then fitted the same day.
Condensation between panes means the sealed unit has failed — the airtight seal has broken down, allowing moisture to enter. This is common in units over 10-15 years old and is accelerated by direct sunlight and Hampshire's coastal humidity.
Yes, in the vast majority of cases we replace only the glass sealed unit and retain your existing uPVC, aluminium or timber frames. This is far more cost-effective than replacing the entire window.
Absolutely. Modern sealed units with Low-E glass and argon gas filling can reduce heat loss through your windows by up to 50% compared to failed units, leading to noticeably lower heating bills.
Single sealed unit replacement starts from £120 per unit, depending on size, glass thickness and access. Individual repairs are priced from £30 (misted units from £120). Every job has a £180 minimum charge.
