Weather Stripping & Seals in Somersworth: Keep Drafts and Damage Out
7 min read
If you've noticed cold air pouring into your garage during winter or water pooling near your garage door after rain, your weather stripping and seals have likely failed. These rubber components protect your home's interior, save energy, and prevent costly water damage. Replacing them costs far less than fixing structural problems down the road.
What Are Weather Stripping and Seals?
Weather stripping and seals are rubber or foam gaskets installed along the edges of your garage door.at the sides, top, and bottom. The bottom seal (also called a threshold seal) takes the most abuse. It compresses under the weight of the door each time it closes, gradually hardening and cracking over 5 to 7 years.
These components do three critical jobs:
- Block drafts that force your heating system to work harder - Keep water out during heavy rain or spring snowmelt - Prevent pest entry by closing gaps where insects and rodents squeeze through
I've seen garages with rotted wooden frames, mold growth, and rusted tools.all because a $150 bottom seal replacement was put off for two years. The damage bill climbed to thousands.
Signs Your Seals Are Failing
Watch for these red flags:
Visible cracks or gaps. Shine a flashlight along the door edges from inside your garage at night. If you see daylight, the seal is compromised.
Water pooling inside. After rain, check the floor near the door. Puddles mean water is seeping past a failed threshold.
Cold air or drafts. Feel along the door frame with your hand in winter. Moving air signals a broken seal.
Pests or insects. Finding spiders, ants, or worse indoors? Gaps in your seals are an open invitation.
Visible rubber deterioration. Cracks, chunks missing, or hardened, brittle material all mean replacement is overdue.

Why Somersworth Winters Make Seals Fail Faster
New Hampshire's freeze-thaw cycles are brutal on rubber. Temperatures swing from below zero to the 40s within days. Water absorbed by aging seals expands when it freezes, cracking them from the inside out. Salt and sand from winter maintenance also degrade rubber faster than in milder climates.
Our team at Somersworth Garage Doors has pulled countless failed seals in March and April.the tail end of winter when damage peaks. If you haven't inspected yours since last fall, now is the time.
Replacement Cost and Process
A same-day estimate typically runs between $150 and $400 depending on which seals need replacement. A bottom seal alone costs $150,$250. If you need all four sides, budget $300,$500. Most jobs take 1,2 hours.
Here's what the process looks like:
1. We inspect all seals for damage and measure the door frame. 2. Remove the old, hardened rubber carefully to avoid damaging the frame. 3. Clean the channel thoroughly to ensure proper adhesion. 4. Install new weather-grade rubber or foam stripping. 5. Test the door operation to confirm smooth closing and proper seal contact.
We keep the most common sizes in stock, which is why we can often complete this work the same day you call. No long waits or emergency surcharges.

DIY vs. Professional Replacement
You *can* buy replacement stripping online and attempt this yourself. The material costs $30,$80. However, I've seen homeowners install it crooked, use the wrong adhesive, or damage the frame channels during removal. A professional installation includes a warranty and guarantees the seals sit flush and seal properly.
If your door has other issues.like the problems described in our limit switch adjustment guide.we'll catch those during our inspection too.
Preventing Future Seal Failure
- Inspect seals twice yearly (spring and fall). - Clean the frame channels of dirt and debris each season. - Avoid slamming the door or forcing it closed if it sticks. - Replace seals proactively before they crack. Don't wait for visible damage.

Frequently Asked Questions
How long do garage door seals last? Most weather stripping and bottom seals last 5,7 years in New Hampshire's climate. Freeze-thaw cycles accelerate wear. Annual inspections help you catch failure before water damage occurs.
Can I replace just the bottom seal? Yes. The bottom seal fails first and can be replaced independently. However, if the side or top seals show cracks, we recommend replacing all three at once for complete protection and consistent appearance.
What's the difference between foam and rubber stripping? Rubber is more durable and weathers freeze-thaw cycles better than foam. Foam is cheaper upfront but hardens and fails faster in northern climates. We recommend rubber for Somersworth homes.
Do weather seals affect garage door balance? No. Seals don't impact the mechanical balance of your door. However, if your door sticks or binds when closing, it may be damaging the seals. Have it inspected by a professional.
Will new seals reduce my heating bill? Yes, noticeably. A failed seal lets warm air escape constantly. New seals can reduce energy loss by 10,15%, depending on how long the old ones were deteriorated.
