Common Window Installation Mistakes to Avoid

Another frequent miss is choosing the wrong type of replacement method for the condition of the opening.

If the wood around the unit is soft, swollen, or rotted, covering it up is not a fix.

The window may look finished, but if the water-management layers are wrong, the wall can start taking on moisture long before anyone notices.

It can help seal joints, but it cannot replace proper flashing, slope, and back-primed surfaces where needed.
