Choosing a Window Repair Specialist in Basingstoke
Check for FENSA Registration or Competent Person Scheme
While not mandatory for repairs, FENSA registration shows knowledge of building regulations. For work in conservation areas, choose a company experienced with local planning requirements and traditional methods like putty glazing.
Ask About Glass Specifications & Guarantees
A good glazier will specify the type (toughened/laminated), thickness, and energy rating (e.g., Low-E, Argon filled) of the replacement unit. They should provide a 10-year guarantee on the sealed unit against misting and a warranty on labour.
Assess Diagnostic Skills & Knowledge of Period Features
They should identify the root cause (failed seal, mechanical stress, impact) and advise on repair vs. replacement. For period properties, they must understand timber window construction, traditional glazing methods, and breathability requirements.
Local Basingstoke, East Sussex Insight
Basingstoke's historic character and rural exposure mean many homes have timber sash windows or early uPVC installations now needing repair. The town's conservation areas strictly control window appearance; always check if your home is in one. For period timber windows, repair is often preferable to replacement to maintain character and value. The local climate with potential for strong winds can stress window mechanisms and seals. Consider upgrading to modern Low-E glass during replacement for better energy efficiency, especially in draughty older homes. For rental properties, ensure all ground floor locks meet insurance requirements. A local specialist will know the common issues with Basingstoke's property types and can advise on the most sympathetic and effective solutions, balancing heritage with performance.
FAQs
Can a misted double glazed window be repaired without replacement?
True sealed unit misting cannot be permanently fixed by drilling or "de-misting" kits. These are temporary and often damage the unit further. The only reliable, long-term solution is replacing the entire insulated glass unit (IGU). Beware of companies offering cheap "permanent" fixes.
How long should a double glazed sealed unit last?
A quality unit should last 15-25 years. Failure often occurs due to seal degradation from UV exposure, extreme temperature fluctuations, poor original installation, or structural stress from building movement.

A quality unit should last 15-25 years. Failure often occurs due to seal degradation from UV exposure, extreme temperature fluctuations, poor original installation, or structural stress from building movement.
When is toughened (safety) glass legally required?
Toughened glass is required in all doors and side panels, windows less than 800mm from the floor, and within 300mm of doors up to 1500mm high. A reputable glazier will know and comply with these Building Regulations (Part K).
Is it worth repairing old uPVC windows or replacing the whole window?
If the frame is structurally sound and not warped, replacing the glass unit and updating hardware is cost-effective (10-25% of new window cost). If frames are discoloured, warped, or mechanisms are obsolete, full replacement may be better for long-term efficiency, security, and aesthetics.
Conclusion
Double glazing repair in Basingstoke costs £80–£170 for a standard misted unit replacement and £42–£95 for lock repairs. Always use a knowledgeable specialist who provides guaranteed sealed units and understands local conservation requirements. For period properties, seek out expertise in timber window repair to preserve character while improving performance, and always check planning constraints before work begins.
Tip:
Clean window frames and tracks regularly to prevent mechanism issues. Slightly open windows during very hot weather to reduce pressure on sealed units. For period timber windows, use a specialist maintenance product (not household cleaner) to preserve the wood and seals. Keep a note of your sealed unit sizes for future reference.
