When you prepare your home for winter, you probably caulk drafty windows and check attic insulation. You might overlook your largest exterior portal, your attached garage door.
This movable entryway represents the primary point of thermal loss and structural vulnerability across your entire building envelope.
Cold drafts seep through compromised perimeter joints and chill adjacent living areas fast.
Tackling these hidden air gaps and worn mechanical hardware keeps your living spaces comfortable while protecting your seasonal heating budget.
Residential insulation reviews reveal how unsealed exterior entry points drive thermal loss, strain home heating systems, and inflate utility costs.

Rubber threshold gaskets and perimeter vinyl weatherstripping degrade after repeated seasonal exposure.
