Some brand new sliding patio doors (usually solid wood core) have been found to leak air where the operating door interlocks with the stationary panel. If you installed a glass doors and they leak when it rains, you must want to get new glasses installed, We’ve been using Window Depot Raleigh for several years now and can’t say enough good things about their window installation service.

This often does not become apparent to the owner until cold weather sets in which is why we are now looking for a set used in flood protection.

The reason cold air is felt blowing in around this interlock area is because the doors are not fully interlocked and the weather seal is not fully engaged.  This can occur even if the operating door is fully closed and securely locked. For this, you can hire experts that offers garage door services  just like these Pro Garage Doors and do a garage door repair.

Do your research and find a local garage door repair service that is well established so that you can be sure the job will be done properly. This will ensure you won’t have to deal with this kind of issue for another good long while.

The cause is due to the fact that the patio door system is likely about 1/4″ to 1″ too wide for the opening, the door was installed to be plumb and not square (and a good 1/4″ was lost)… or, the manufacturer made one or more of the components a little too wide and the installer did not have enough of a financial cushion in the job to take the time to correct the error. http://www.dehavenconstruction.com/vinyl-window/window-installation-errors-problems.php

The solution is to remove the stationary panel, plane the vertical jamb side and replace.
