Garage Conversions And Alterations


At Eastern Garage Doors, we provide garage door conversions and alterations, which provide you with the space, height or length (or both), that you need to make the most of your garage space. We also carry out fit out conversions whereby we insulate and dryline the walls and ceiling, provide specialist flooring and built in cupboards and shelving.

We can remove the central pillar on your garage, which widens the entrance space and increases the height and sometimes the length of the garage. We can also look at ways of increasing space without the need for lengthy building works.

Garage Conversion Service – Convert Your Garage Space!

 Garage alterations are extremely useful as most modern cars are wider nowadays, plus wing mirrors have increased in size, or in the instance that you own an unusually tall or wide vehicle since you can comfortably accommodate its size.

Our highly trained professionals are committed to ensuring you get the garage and doors you want and need. Our regional teams are highly trained specialists in all aspects of garage conversion and alterations.

Once the conversion or alteration is undertaken, we ensure we adhere to the highest possible standards, to ensure that we provide our customers with something that is not only practical but also stylish and durable for many years of reliable use.
