Servicing and repairs


Garage Doors Width Modifications

If you require a wider garage door, Southern Doors provides professional garage door widening to your specifications. By removing the garage’s central pillar between two smaller garage doors, your widened garage will permit increased capacity and improved accessibility for wider vehicles. The entire operation is performed with security and safety in mind, which is why we reinforce the lintel with a steel beam before installing the new, wider garage door.

Homeowners and business owners with garages on their premises choose to widen garage doors for many reasons, but some of the most common include:

  • Increased room for wide vehicles
  • Improved accessibility for the elderly and less-abled
  • More space for your storage needs
  • One door results in less ongoing maintenance and less expense

Southern Doors can provide you with a free, no-obligation survey to help you determine if garage door widening is right for you.

The company were very helpful when I first inquired about the job that needed doing. Austin H arrived on time and due to the current circumstances ( covid19) kept social distance and within 45 minutes had the job done, and he explained what he had done. Thank you eastern group UK garage doors

Engineer Austin Humphris came to service and check fault with my Markilux awning, which was purchased from Sandersons over 13 years ago. Within a short while awning was working again. I was impressed with the service and polite manner. I would not hesitate to recommend this company for any work you need carried out.


I rarely write reviews but the service that I have just had from Eastern Group merits one. All aspects of the service from my first enquiry to the installation have been professional, timely and courteous. I cannot fault them. The outcome is an excellent and well-fitted door. I highly recommend them.
