Frequently Asked Questions


What does a garage door seal actually do?

The seal's primary function is to close the gaps between your garage door and the floor, blocking out air, moisture, and even pests. A properly sealed door prevents cold drafts in winter and keeps hot air out during summer, so your heating and cooling systems don't have to work overtime. It also helps protect your belongings from water damage, dust, and pests.

How does a worn seal affect my energy bills?

A damaged seal allows outside air to flow in and out freely, which can cause heating and cooling costs to rise over time. When the seal works properly, your heating and cooling systems don't have to work overtime, leading to reduced energy bills. This benefit is even more noticeable for homes with attached garages.

How can I tell when my garage door seal needs replacing?

Worn seals usually show clear warning signs. Look for cracks, gaps, or sections peeling away along the bottom of the door, rainwater or debris sneaking underneath, and higher energy bills. You can also stand inside the garage during daylight hours and check for light peeking through the bottom of the door.

How can I stay ahead of seal problems before they get worse?

You should consider replacing a garage door seal as soon as you spot a problem to avoid bigger issues like drafts or water damage. To prevent potential breakages, schedule annual inspections with a trusted garage door company. This proactive approach lets you address issues early with confidence and ease.
