General Tune-Ups

An 8′ Wide Vinyl Sliding Patio Door Assembly. You can probably see the problem even in this photo.

This wall, or this end of the house has substantially settled, throwing the door opening out of square.

And my technician Brandon Todd told me that this was with the rollers adjusted as far as they could be to offset the opening being out-of-square.

How far out-of-square you ask? Well if you take your tape measure from one corner of the door frame to the opposing corner, we are showing 121 3/4″.

When measured from the other top corner down to the opposite bottom-corner, we have 123″. Yep…that’s 1 1/4″ out-of-square.

So we pulled the door assembly, cut some 8′ long tapered shims to place under the door, setting the door assembly level with gravity and square with itself.

The good news is that this allows the door to fit in the jamb assembly as it is meant to do. The bad news is that now the door assembly really looks crooked as it relates to most all other surrounding structural indicators.
