    How much does door installation cost?

    The cost of door installation can vary depending on factors such as the type of door, the complexity of the installation, and the location. For more information, speak to us today for a free, no-obligation quote.

    Do I need to replace the entire door frame during installation?

    In many cases, it is not necessary to replace the entire door frame during installation. If the existing frame is in good condition and properly aligned, a new door can often be installed within the existing frame. However, if the frame is damaged, warped, or not properly aligned, it may need to be replaced or repaired to ensure proper installation.

    Can I install a new door in an existing wall?

    Yes, it is possible to install a new door in an existing wall. However, this can be a more complex and involved process compared to replacing a door within an existing frame. It may require cutting an opening in the wall, installing a new frame, and properly finishing the surrounding area.

    Are there any specific requirements for door installations in terms of building codes?

    Yes, there are building codes and regulations that dictate certain requirements for door installations, particularly for exterior doors. These codes typically cover aspects such as fire safety, accessibility, energy efficiency, and structural integrity. At Global Windows, we’re able to assist you in meeting all the necessary requirements for your door installation.

    New Window and Window Swap

    Had Global swap an existing window for a new bi-fold door and install a completely new window in our dining room. As hoped, both have created a lot of addition light. I have used Global in the past and would use again in the future. Professional service provided from the office staff. They were the only business I spoke to that was aware of the new building control regulations that were introduced at the start of October last year and therefore acted as Principal Designer keeping the works compliant. The guys that completed the work were very respectful, polite and tidied up after themselves. Would recommend.
