**Energy efficiency** Double glazing helps keep heat in your home, but if the seal breaks, warm air can get in and reduce the window's efficiency, leading to higher energy bills. Old double glazed units are a lower specification to modern ones, so we can also replace these units with new which increases their effectiveness. - **Condensation** If the seal breaks, moisture can get into the unit and cause condensation on the inside of the glass. ##### When to replace a double glazed unit? - If the window is steaming up or has condensation on the inside - If your energy bills have increased The lifespan of double glazed windows is usually 15–20 years, but this can vary depending on the quality of the window, how it was installed, and how well it's maintained. ![Window Repairs](https://www.harveyswindows.co.uk/hubfs/Harveys_Windows_Theme/Window-repairs.svg) ##### Window repairs [![Read More](https://hubspot-no-cache-eu1-prod.s3.amazonaws.com/cta/default/19927398/85132890-6837-4f81-bee0-52ebf57d7aee.png)](https://hubspot-cta-redirect-eu1-prod.s3.amazonaws.com/cta/redirect/19927398/85132890-6837-4f81-bee0-52ebf57d7aee) ![Harvey Windows](https://www.harveyswindows.co.uk/hs-fs/hubfs/Harvey_Windows_Logo-removebg-preview.png?width=100&height=101&name=Harvey_Windows_Logo-removebg-preview.png) #### Window repairs ![Window repairs](https://www.harveyswindows.co.uk/hs-fs/hubfs/Harveys_Windows_Theme/Unit%20change%20F.jpg?width=200&height=200&name=Unit%20change%20F.jpg) Minor damage to uPVC windows can often be repaired, but major damage may require a full replacement. The severity of the damage determines whether it's best to repair or replace the window. ##### **Types of window repair** - ** Fix loose handles or hinges: ** These can either be refixed or replaced as needed - ** Repair scratches or dents:** It is possible to repair some minor scratches or dents to the frame. - ** Clean discoloration:** Special cleaning solutions designed for uPVC can be used to remove some build up. - **Apply silicone spray: ** A silicone spray or other suitable lubricant can keep moving parts working well for longer, especially in the case of locks and hinges. - ** Replace the frame:** If the frame is cracked or severely warped, it might be beyond repair. We can advise you if this is the case and provide an estimate for replacement. - **Replace the glass: ** If the glass is cracked or broken, it can usually be replaced without needing to change the whole frame. - **Replace the locks: ** If the locks are faulty, sticking or not operating at all we can identify the correct type to replace them. - ** Replace seals or weather gaskets:** This can improve insulation. ![Door repairs](https://www.harveyswindows.co.uk/hubfs/Harveys_Windows_Theme/Door%20repairs.svg) ##### Door repairs [![Read More](https://hubspot-no-cache-eu1-prod.s3.amazonaws.com/cta/default/19927398/0c9426d6-47e3-4467-a202-78d1ebdd866b.png)](https://hubspot-cta-redirect-eu1-prod.s3.amazonaws.com/cta/redirect/19927398/0c9426d6-47e3-4467-a202-78d1ebdd866b) ![Harvey Windows](https://www.harveyswindows.co.uk/hs-fs/hubfs/Harvey_Windows_Logo-removebg-preview.png?width=100&height=101&name=Harvey_Windows_Logo-removebg-preview.png) #### Door repairs ![Door repair](https://www.harveyswindows.co.uk/hs-fs/hubfs/Harveys_Windows_Theme/Door%20repair.jpg?width=200&height=267&name=Door%20repair.jpg) UPVC door repairs can involve correcting misalignment or changing locks, hinges and more.
