Garage Conversions And Alterations


Here at Eastern Garage Doors, we offer garage door alterations and conversions, providing you with extra space, height, or length to maximise the space in your garage. We offer building work to remove the central pillar on your garage, widening the door and entrance space, and can also increase the height and length of your garage by installing a specialist door to maximise the storage potential.

Garage alterations can be extremely useful for tall or wide vehicles, ensuring your garage is converted to accommodate the size of your vehicle. Converting your double garage into a full width door also provides more usable space, and a more accessible garage space.

For more information on the garage conversion and widening services we offer, feel free to contact us today. We operate in Norfolk, Cambridgeshire and across all East of England and into North London, and provide a no obligation onsite survey for your added convenience.
