Garage door issue due to floor not being level

[Mark M]

It appears there has been some movement in the foundations/floor over the years and the garage door has a gap of 2-3 cm on one side wheareas the other is fine. Its a double garage roller shutter that was installed when the house was built approx 29 years ago which is still going strong in all fairness. The garage floor is slightly raised from the driveway so there are thankfully no issues with water getting in but we get a load of mice in which isnt ideal! Plus the garage is freezing all of the time although not sure if thats linked to the gap.

There is a man hole in the garage so I cant lay self levelling concrete unfortunately but do I have any other options?

Solution aside, you should try to identify the source of the problem first, as it could get worse over time.

We had a survey done when we bought the house and further work was carried out which identied that any movement has now stopped we’re assured.
