It was easy to contact, easy to schedule a date, installer was knowledgeable and did a great job. Removed my old door, installed my used door and used opener (didn't have an opener before). Good pricing, but most of all great job installing, especially all my used parts and unlevel concrete.

If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
