Weather Stripping & Seals in Duarte: Stop Drafts, Save Energy
2026-05-15 7 min read
A customer called last Tuesday asking why her garage felt cold even though the door looked fine. After a quick inspection, I found the bottom seal had cracked and separated from the frame. She'd been losing heated air all winter without realizing it. That's exactly the kind of problem we catch every week here in Duarte. Weather stripping and seals are small parts that make a huge difference in your energy bills, comfort, and how well your garage door actually seals against outside elements.
Why Weather Stripping & Seals Matter More Than You Think
Your garage door isn't just about opening and closing. It's a barrier between your home and the outside air. Weather stripping lines the edges of the door, while the bottom seal (called a threshold seal) takes the biggest beating. They stop wind, rain, dust, and pests from getting inside. They also help keep conditioned air from escaping. See our guide on how to choose the right garage door for your home.
In the San Gabriel Valley, our temperature swings can be extreme. Summer heat and winter drafts both put stress on these seals. When they wear out, you'll notice higher heating and cooling costs. Your HVAC system works harder. Small pests find their way in. Moisture sneaks underneath and can damage your flooring or stored items.
Most homeowners don't think about seals until something else breaks. But replacing worn weather stripping before a bigger problem develops is smart maintenance. It's affordable, quick, and pays for itself through lower utility costs within a season or two. Read about smart garage door technology in duarte: wifi, apps & home automation explained.
Signs Your Weather Stripping Needs Replacement
Look for visible cracks, gaps, or hardened rubber along the edges of your door. If the bottom seal is peeling away from the frame, air is definitely leaking. You might feel a draft near the garage door on a windy day. Some people notice small bugs or spiders inside the garage near the door frame. Water stains on the floor near the door are another red flag.
Age matters too. Weather stripping typically lasts 5 to 7 years depending on sun exposure and climate stress. If your door is older and you haven't replaced the seals, now's the time to check them. Our team at Garage Door Duarte can spot worn seals in minutes during a free inspection.

Cost and Installation: What to Expect

Types of Weather Stripping & Materials
Not all seals are the same. The most common materials are rubber, vinyl, and silicone. Rubber is durable and affordable but can harden in direct sun. Vinyl stays flexible longer and resists UV better. Silicone is premium but lasts the longest, especially in hot climates like ours.
The bottom seal is the workhorse. It takes impact from debris, temperature changes, and moisture. We usually recommend a heavier-duty material for that position. Side and top seals can use lighter vinyl or rubber since they see less stress.
