Weather Stripping & Seals in Platteville: Stop Drafts, Save Energy
2026-08-25 7 min read A2Z Garage Doors
Weather stripping and seals are the quiet guardians between your garage and the Colorado elements. They stop drafts, block dirt and pests, and lower your heating and cooling costs. If your garage door leaks air or light around the edges, your seals need attention. The good news: this is one of the most straightforward fixes we handle, and it works.
Why Weather Stripping Fails in Platteville's Climate
Platteville sits in a zone where temperatures swing hard. Winter dips below freezing, and summer heat climbs. That constant expansion and contraction wears rubber and foam seals faster than you'd expect.
The bottom seal takes the worst abuse. It drags across concrete, absorbs moisture from snow melt, and hardens over time. Most bottom seals last four to six years before they crack or lose their grip. Threshold seals wear similarly. Side seals and top seals degrade slower, but they still break down.
UV exposure accelerates the problem. Colorado gets over 300 days of sun annually. That relentless light degrades rubber compounds, making them brittle and less effective at blocking drafts.
How to Spot Failing Seals
Look for visible gaps or light bleeding around the door frame when it's closed. Run your hand along the bottom seal in winter. If you feel cold air or see daylight, replacement is due. Dust accumulation on the garage floor near the door edges signals a failing threshold. Listen for whistling or humming sounds during windy days. That's air moving through compromised seals.
Check the seals yourself once a year. This takes five minutes and costs nothing except attention.
Types of Weather Stripping & Seals for Your Garage Door
Not all seals are created equal. The type you need depends on where the draft is coming from.
Bottom seals are rubberized strips that hang from the base of your door. They compress against the concrete threshold. Most are replaceable without removing the door. Vinyl and EPDM rubber are standard. Vinyl costs less but wears faster in Colorado's UV environment. EPDM lasts longer and handles temperature swings better.
Side seals run vertically along both jambs. They keep wind and rain from sneaking in around the edges. These attach to the frame and press against the door panel as it closes. Foam, rubber, and vinyl options exist, each with different durability profiles.
Threshold seals sit on the concrete and create a barrier below the bottom seal. They fill the gap between the door and the floor. Aluminum thresholds with rubber inserts are durable and easy to clean.
Top seals prevent air from leaking above the door. They're often overlooked but matter in older installations or doors that don't seal flush at the top.

Cost and Installation Considerations
A full seal replacement for a single garage door typically runs between $150 and $400, depending on material quality and how many seals need replacement. Bottom seals alone cost $75 to $200. Thresholds range from $100 to $250. These aren't guesses. We've installed thousands of seals in Platteville and the surrounding region.
DIY replacement is possible for bottom seals on some doors. The process involves unbolting the old seal and sliding a new one into place. But if your door is older or the mounting brackets are corroded, professional installation saves frustration.
More importantly, we inspect the entire door frame and bottom panel during installation. Damaged concrete, bent frames, or warped panels affect seal performance. You can have perfect seals on a door that doesn't close properly. We fix the root cause, not just the symptom.

When to Replace vs. When to Repair
Fresh caulk or adhesive can sometimes extend a seal's life by a year or two. But once a seal is cracked, compressed, or missing chunks, replacement is the only real fix. Partial repairs create uneven gaps, which defeat the purpose.
If only one seal is failing (like the bottom), you can replace just that one. But if you're already having the door serviced, replacing all seals at once costs less in labor and gives you a fresh start. Most seals age at similar rates, so a full replacement makes sense if the door is over five years old.
Replace seals before winter arrives. Fall is the ideal time in Colorado. You'll catch problems before the heating season and avoid emergency calls when temperatures drop.
