When you notice you have a damaged window screen, it is in your interest to get it fixed as soon as possible. Window Screen Chips can lead to your screen cracking, no matter how small they look, especially with the British roads and the underinvestment by the British government and local councils. Once you have a chip or crack in your window screen then the integrity of the strength of the glass has been weakened. The longer the damage is left unrepaired, then moisture and dirt can enter and this could reduce the chances of getting a good repair.
There are different types of breaks and chips in your glass, these are known as Star Break, Bullseye, Combination Breaks, Half Moon, Clover Leaf & Bees Wing.
Not all chips and cracks can be repaired which would mean a new glass replacement would be required. G & G do not replace window screens, we simply repair the chip in your glass. G & G would expect anywhere between 70% (lower end) to over 85% (high end) success of the repair visibility in the screen. Once the repair has been completed your screen will be back to full strength.
