PVC windows are known for their durability and low maintenance, but even they don’t last forever. Over time, seals wear out, hinges loosen, and frames lose their airtightness. So, should you repair old windows or invest in new ones?
When repair is enough:
If the issues are minor — difficulty closing, small drafts, or worn seals — repair is usually the most practical and affordable option.
– Replacing rubber seals restores insulation.
– Adjusting hinges and handles eliminates air leaks.
– Cleaning frames and renewing silicone extends the window’s lifespan.
Such maintenance is cost-effective and can add several years of service life.
When replacement is the smarter choice:
If your windows are over 15–20 years old, their energy efficiency may no longer meet modern standards.
– The glass unit might be foggy or cracked.
– Frames may have warped or discolored.
– Locks and fittings might no longer function properly.
In these cases, new energy-efficient windows can significantly improve comfort and reduce heating costs.
Conclusion:
Small defects can be repaired, but if your old PVC windows are wasting energy, upgrading to new ones is a long-term investment that pays for itself through lower bills and better living conditions.
