Every winter, the residents of Lincoln, Nebraska, face a familiar challenge: keeping snow, ice, and frigid air out of their garages. One of our customers in northeast Lincoln experienced this firsthand. Their garage door had a deteriorated bottom seal and faulty door weather stripping, which allowed snow to drift inside during a blizzard. This resulted in significant water damage, ruined storage boxes, and a costly HVAC repair due to the cold air infiltrating their home. Unfortunately, their story is not uncommon in this part of the Midwest, where weather conditions can be unforgiving.
According to the National Weather Service, Lincoln receives an average of 26 inches of snow each year, and temperatures often plunge below freezing for weeks at a time. The city also experiences strong wind gusts, sleet, and freezing rain, all of which can exacerbate issues related to poor garage insulation and inadequate weatherproofing. In such conditions, weatherproofing your garage with effective weather sealing is not just a good idea; it is essential for protecting your property, improving energy efficiency, and maintaining indoor comfort for your family and belongings.
At Salt Creek Garage Doors, we specialize in comprehensive weather sealing services for both residential and commercial garage doors. We provide expert solutions using industry-standard tools and materials, such as EPDM rubber, foam seal tape, silicone caulk, aluminum thresholds, and more. Our experienced technicians have seen firsthand how a well-sealed garage can prevent expensive repairs, safeguard stored items, and create a safer, more comfortable environment. Our goal is to help homeowners and business owners in Lincoln secure their garages against the elements and enjoy year-round protection.
What Is Weather Sealing and Why Is It Crucial?
Weather sealing refers to the installation of various products and systems that close the gaps around your garage door and frame. These include bottom seals, side seals, threshold seals, door sweeps, foam weatherstrip tape, and more. These components work together to prevent air leaks, water infiltration, pest intrusion, and heat loss.
For example, a properly installed garage door bottom seal made from EPDM rubber can block wind-driven snow from entering your garage. A foam seal installed around the door frame prevents cold air drafts from seeping through the edges. When used in conjunction with garage insulation and door trim seals, these components create a nearly airtight environment that protects your home from both the cold and moisture-related issues.
Weather sealing also plays a key role in condensation prevention. By keeping warm indoor air from contacting cold surfaces, you reduce moisture accumulation that can lead to mold growth, rusting metal, or warped wood. This is especially important for garages that are used as workshops, storage areas, or home gyms. As a result, a well-sealed garage remains cleaner, drier, and structurally sound throughout winter and beyond, saving homeowners time and money on maintenance and repairs.
Understanding the Components of Garage Door Weather Sealing
Garage Door Bottom Seal
The garage door bottom seal is one of the most critical lines of defense against weather and pests. It is typically a rubber or vinyl strip that compresses against the floor when the garage door closes. Over time, however, it can develop cracks, wear out, or lose flexibility due to repeated exposure to temperature changes, road salt, and moisture. Seasonal replacement is often required to maintain its effectiveness.
When installing a new bottom seal, using tools like a utility knife, measuring tape, and installation adhesive ensures a proper fit. If the bottom seal does not sit flush with the ground, it can leave gaps that allow cold air and snow to enter. In cases where the garage floor is uneven, installing a U-shaped EPDM rubber seal or combining it with a threshold seal offers better protection. Adding a draft stopper under the door enhances its performance further, especially in windy conditions.
Threshold Seal
A threshold seal is mounted directly on the garage floor and works in tandem with the bottom seal. Made from durable vinyl or rubber, it helps create a tighter seal and prevents water from flowing under the door. Threshold seals are particularly useful for garages with sloped or cracked concrete, where water tends to pool. In commercial settings, aluminum thresholds are often preferred for their durability and resistance to heavy foot and vehicle traffic.
To install a threshold seal correctly, it is essential to thoroughly clean the surface with a degreasing agent, measure the length accurately, and use a sealant gun with high-quality installation adhesive. A properly installed threshold can withstand years of use and act as an effective barrier against not only water but also pests and airborne pollutants.
Side Seal and Top Door Weather Stripping
Side seals and top weatherstripping close the gaps around the vertical and horizontal edges of the garage door. These strips are often made from vinyl trim, foam tape, or brush-style materials. Side seals also serve as barriers against insects, wind, and debris.
The installation of these seals requires precision. Using miter shears allows for accurate angle cuts, especially at corners, while a caulking gun ensures a secure and uniform application of adhesive. In Lincoln, where snow can be windblown, sealing all sides of the garage door prevents snow intrusion and reduces heating loss. Homeowners should inspect these seals regularly, looking for signs such as brittle material, gaps, or compression loss, which are common indicators of seal deterioration.
Additional Draft Stoppers and Insulation Solutions
Beyond the main door seals, other products can enhance the weatherproofing of your garage. These include:
- Foam weatherstrip tape: Ideal for sealing smaller gaps in door joints and window frames. It provides a quick fix and is easy to apply without specialized tools.
- Adhesive rubber seal: This is a flexible and durable solution for doors and access panels. It adheres well to various surfaces, including metal and wood.
- Magnetic door strips: These are especially effective for steel garage doors and provide a tight seal without constant compression wear.
- Window insulation kits: These contain heat-shrink film and double-sided tape to improve energy efficiency around garage windows. When used with a heat gun, the film shrinks tightly, blocking drafts.
- Silicone sealant and foam caulk: Ideal for filling irregular gaps or cracks in frames and walls. These materials remain flexible in cold temperatures and are waterproof.
Implementing a combination of these products ensures a comprehensive weatherproofing strategy. Recommendations from agencies like Energy Star (EPA), ASHRAE, and the Department of Energy confirm that well-sealed garages significantly reduce energy consumption and heat loss.
Seasonal Seal Maintenance and Replacement Tips
Lincoln’s changing seasons can be harsh on garage door seals. Frequent freezing and thawing cycles cause rubber seals to harden, shrink, or crack. Ice buildup during winter storms and UV exposure in summer also contribute to material degradation. This is why regular inspections and timely replacements are so important.
Start your inspection by closing the garage door during daylight hours. Look for sunlight coming through gaps or feel around the edges for cold drafts. Common trouble spots include corners, the bottom edge, and where the side seals meet the floor. If you discover a cracked seal or a loose door sweep, it is time for a replacement.
To replace seals, first remove the old material using a utility knife or flat scraper. Clean the area thoroughly with a wire brush and degreaser. Use a measuring tape to cut the new seal to the appropriate length. Apply installation adhesive carefully and press the seal firmly into place, ensuring a snug and uniform fit. Let the adhesive cure as recommended before using the door.
Our team at Salt Creek Garage Doors recommends inspecting your garage door weather sealing every fall, ideally before the first snowfall. A simple maintenance schedule, combined with seasonal seal replacement, can extend the life of your garage door system and keep your garage warm and dry.
The Role of Proper Tools and Techniques in Installation
Installing weather seals requires precision, especially when dealing with variable floor heights, warped door frames, or wide garage openings. Basic tools include a utility knife for trimming, shears for angle cuts, a sealant gun for applying adhesive, a caulking gun for sealing cracks, and a heat gun for shrinking insulation film.
Each tool plays an important role. For example, using miter shears allows you to create clean, angled cuts for corner joints, which improves the seal’s overall effectiveness. A sealant gun ensures even distribution of installation adhesive, preventing gaps or weak spots. A heat gun helps form a tight, wrinkle-free seal around window insulation film, enhancing thermal performance.
Salt Creek Garage Doors uses commercial-grade materials and industry-approved techniques to guarantee long-lasting performance. Our technicians are trained to recognize when a standard vinyl sweep is not sufficient and may suggest a more robust EPDM rubber seal or a foam-backed aluminum threshold for better protection. We also ensure that all installations meet safety standards set by Underwriters Laboratories (UL) and the International Code Council.
The Impact of Weather Sealing on Energy Efficiency
One of the most significant benefits of garage door weather sealing is improved energy efficiency. A well-sealed garage prevents heat loss, reduces the workload on your HVAC system, and maintains a more consistent indoor temperature. This is especially important in attached garages, where cold air can infiltrate living spaces and drive up heating costs.
According to the Department of Energy (DOE), sealing gaps and insulating garages can reduce energy bills by up to 20 percent. In colder regions like Lincoln, this translates into real savings throughout the winter season. Sealed garages also maintain higher temperatures, which can prevent freezing of pipes, extend the life of vehicles, and improve the comfort of any adjacent rooms.
Weather sealing also enhances the performance of garage insulation systems. If your garage walls and ceiling are insulated but the door is not sealed properly, the effectiveness of the insulation is compromised. Installing a thermal curtain, window insulation film, or door sweep kit can complement your insulation efforts and further reduce energy waste. In some cases, adding reflective insulation to the back of the garage door can enhance R-value and provide an extra layer of protection.
Weather Sealing for Commercial Properties in Lincoln
Commercial garages in Lincoln face unique challenges during snowstorms and severe weather. From auto shops to warehouse loading docks, large garage doors often have more surface area and are exposed to heavier use. This makes reliable weather sealing a business-critical requirement for maintaining operational efficiency and workplace safety.
Our team at Salt Creek Garage Doors has worked with numerous businesses to install brush-style door sweeps, heavy-duty aluminum thresholds, foam tape, and magnetic door strips. We assess variables such as door material, daily usage, exposure to elements, and compliance with regulations from organizations like the International Code Council and Underwriters Laboratories (UL).
Commercial-grade sealing not only protects assets and inventory but also ensures a safe and comfortable work environment for employees. It helps regulate indoor temperature, reduces condensation around equipment, and prevents costly downtime caused by weather-related disruptions. We offer tailored solutions, including high-durability adhesive door seals and custom door trim seal systems, designed specifically for the demands of commercial applications.
Preventing Mold and Moisture Damage Through Proper Sealing
Moisture infiltration is a hidden threat in garages, especially during Lincoln’s wet winters. When warm air from the home meets the cold surfaces of an unsealed garage, condensation forms. This creates an ideal environment for mold, mildew, and even structural decay. Over time, trapped moisture can warp wooden frames, corrode metal tools, and degrade insulation materials.
Weather sealing helps regulate temperature and humidity levels within the garage. Foam seals and threshold seals act as barriers against water intrusion, while door sweeps and foam weatherstrip tape keep airborne moisture from circulating. Silicone caulk and foam caulk can be used to seal gaps around vents, outlets, and utility penetrations to prevent moisture entry.
Homeowners who store tools, electronics, or seasonal items in their garage benefit significantly from moisture control. Preventing mold not only protects your belongings but also promotes healthier indoor air quality. This is particularly important for homes with attached garages, as mold spores can travel into living spaces and trigger allergies or respiratory issues.
Common Mistakes to Avoid in Garage Door Sealing
While many homeowners attempt to install their weather seals, some common mistakes can reduce their effectiveness. These include:
- Failing to clean surfaces thoroughly before applying adhesive door seals, which leads to weak bonding
- Using the wrong size or material for your specific door type results in a poor fit and reduced performance
- Installing foam tape too tightly, causing it to compress and lose its sealing ability over time
- Ignoring deteriorated side seals or top trim, which can allow significant drafts and moisture to enter
- Overlooking the need for a backup drainage solution when water buildup is persistent, especially near threshold areas
Avoiding these pitfalls ensures longer-lasting and more effective sealing. When in doubt, consult a professional for a detailed seal inspection, accurate material recommendations, and proper installation techniques tailored to your specific garage layout.
