Many people have gated entrances to their driveways as an added security measure. Depending on what types of gates you want and the technology they will use can vary the price drastically. Some of the most high tech security gates have keypad or remote entry, video surveillance and even some are linked up to a security firm who will be notified should they be tampered with.
Adding security to your home can drastically reduce you house insurance price whilst giving you that added peace of mind and this is something that you cannot put a price on.
Do not be afraid to shop around and get a few quotes to find the best price for security gates and make sure you ask about any extras you may want prior to ordering as often trying to add something on after the gates have been built will increase the price substantially.
