While not always mandatory for repairs, membership in FENSA (Fenestration Self-Assessment Scheme) or DGCOS (Double Glazing & Conservatory Ombudsman Scheme) indicates a reputable firm that adheres to industry standards. Crucially, ensure they have public liability insurance to cover any damage during repair. For sealed units, check they use BFRC rated energy-efficient glass. Can they identify and source parts for your specific window brand (e.g., Rehau, Veka, Spectus)? Do they understand the impact of Petersfield's coastal climate on seals and hardware? For period properties in conservation areas, can they repair sensitively or replicate the look with modern double glazed units? A local company will have experience with the common issues in the area. Avoid vague verbal quotes. Request a written breakdown specifying: part costs (e.g., unit size/type, hinge model), labour, and VAT. Ask about the warranty on the new sealed unit (typically 5-10 years) and on the labour. Be wary of prices that seem too good to be true – they may be using poor-quality glass or non-branded parts that won't last. Double glazing in Petersfield faces a harsh environment. Salt-laden air significantly reduces the lifespan of rubber seals, meaning misted units and draughts appear sooner than inland. The prevalence of holiday lets with high guest turnover leads to more frequent mechanical failures (handles, locks). Many properties installed UPVC windows in the 1990s/early 2000s, and these are now reaching the age where seal failure is inevitable. For homes in conservation areas, finding a company that can supply slim-profile double glazed units for timber sash windows is a valuable skill. Due to the coastal weather, ensuring repairs are done with weather-resistant parts is key. Always opt for a local specialist over a national call-out service for faster response and better knowledge of sourcing parts for older installations. It must be replaced. Misting indicates the hermetic seal has failed, allowing moisture between the panes. The unit cannot be re-sealed effectively. The entire Insulated Glass Unit (IGU) needs to be manufactured new and fitted into the existing window frame. If the frames are structurally sound and not discoloured, repair is usually far more cost-effective than full window replacement. Replacing a misted unit or a faulty mechanism can extend the life of the window by many years for a fraction of the cost of new windows. For a standard unit in a straightforward casement window, an experienced technician can typically remove the old unit and fit the new one in 30-60 minutes. However, manufacturing the new unit to size takes time – allow 5-10 working days from order to installation. This is usually due to: 1) Worn or seized hinges, 2) A misaligned frame (settling of the property), or 3) Dirt/debris in the tracks or mechanisms. A technician can diagnose and usually fix this by replacing hinges or adjusting the frame. Double glazing repair in Petersfield costs £120–£250 to replace a standard misted sealed unit and £40–£85 to replace a faulty window lock. Given the local coastal climate that accelerates wear, prompt repair of seals and mechanisms is key to maintaining comfort, security, and energy efficiency. Always use a reputable local company that provides a clear warranty on parts, and consider preventative maintenance like seal checks to extend the life of your windows, especially for holiday lets where performance and security are critical. Clean and lightly lubricate window tracks and mechanisms with a silicone spray (not WD-40) annually to prevent sticking. Address minor draughts promptly before they worsen. If you have a misted unit, act quickly to prevent potential condensation damage to the frame interior. Keep the contact details of a good local repair company handy, especially for holiday lets.What Affects Double Glazing Repair Prices in Petersfield?
