When Weatherstripping Needs Replacing
Daylight under the door
If you can see daylight, cold air and pests are getting in.
Snow blowing into garage
Bottom seal is cracked, torn, or has pulled out of the retainer.
Cracked bottom rubber
Wisconsin cold makes old vinyl bottom seals brittle — cracks appear each winter.
Ice building at threshold
Missing seal lets snowmelt puddle and freeze at the door opening.
Drafts along the sides
Side stops (jamb weatherstripping) have shrunk, torn, or fallen away.
Water on garage floor
Rain being driven in around the perimeter of the door.
Leaves piling inside
Bottom seal isn’t sealing against the driveway anymore.
Loud rattling
Loose weatherstripping flaps in wind — easy fix and a lot quieter after.
How We Reseal Your Garage Door
We measure the door, verify the retainer profile (T-style, bead, or bulb), and cut the correct cold-rated replacement stock to fit. Bottom seal replacement takes about 20 minutes on a standard 16-foot door. Side and top jamb stops add another 20 minutes.
For homes with uneven concrete under the door, we can install a threshold seal in addition to the door’s own bottom seal — a two-piece system that closes irregular gaps and keeps snowmelt outside where it belongs.
- Cold-rated bottom seal (T-style, bead, or bulb)
- New side & top jamb weatherstripping
- Threshold seals for uneven concrete
- Whole job typically under an hour

Frequently Asked Questions
How often should garage door weatherstripping be replaced?
Bottom seals usually last 3–5 winters in Wisconsin — UV, cold, and salt shorten the life. Side stops last longer, typically 7–10 years.
Can I install the bottom seal myself?
You can, but sizing the T-profile to the retainer is where DIY jobs usually fail — wrong profile pops back out. We match it correctly the first time.
Does new weatherstripping really help heating costs?
For attached garages, yes — sealing the door drops garage temperature swings and reduces heat loss from the shared wall to your house. Not a huge line-item saving, but noticeable comfort.
Do you install threshold seals?
Yes. Threshold seals adhere to the concrete right under the door and work with the bottom seal to close uneven gaps. Great for older concrete driveways.
How is a weatherstrip job quoted?
Bottom-seal-only is the quickest and lowest cost. Adding side and top jamb weatherstripping is a step up. A full perimeter reseal with a threshold seal is the most involved. We look at the door and quote before we start.
