Weather Sealing & Insulation
Comprehensive weather sealing and insulation services that protect your garage from Arizona heat, dust, and monsoon storms.
Making Life Better In Greater Phoenix & East Valley
Arizona’s climate is hard on garages. Summer temperatures push well past 115 degrees, fine desert dust finds its way through the smallest gaps, and monsoon storms drive rain sideways into openings you did not know existed. Proper weather sealing and insulation are essential for keeping your garage comfortable, clean, and energy-efficient. At Runyon Construction Group, we provide comprehensive weather sealing and insulation services for garage doors and garage structures throughout Greater Phoenix, the East Valley, and Maricopa and Pinal counties.
The bottom seal is the most important weather seal on any garage door, and it is often the first to wear out. We replace worn, cracked, or missing bottom seals with heavy-duty rubber or vinyl strips that form a tight barrier against dust, water, insects, and rodents. For uneven garage floors, we install threshold seals that mount directly to the concrete and create a raised lip the door compresses against when closed.
Side and top seals (also called astragal and header seals) close the gaps between the door panels and the door frame. Over time, these seals dry out, crack, and lose their flexibility in Arizona’s heat and low humidity. We replace them with UV-resistant rubber and vinyl weatherstripping that maintains its seal through years of temperature extremes.
Between-panel seals prevent air and dust from infiltrating through the joints between individual door sections. These flexible gaskets compress when the door is closed and expand when it opens, maintaining a tight seal throughout the door’s operation. Replacing worn panel seals can make a noticeable difference in how much dust accumulates inside your garage.
For garages that double as workshops, home gyms, or hobby spaces, we offer full insulation upgrades. We install rigid foam board or reflective barrier insulation on garage walls and ceilings, and we can retrofit existing non-insulated garage doors with insulation kits that attach directly to the door panels. While retrofit insulation does not match the performance of a factory-insulated door, it provides a significant improvement over bare steel.
We also address air leaks around service doors, windows, electrical penetrations, and where the garage structure meets the house wall. Sealing these gaps with caulk, spray foam, and weatherstripping creates a tighter building envelope and reduces the amount of conditioned air that escapes from your home into the garage.
We serve homeowners across Chandler, Gilbert, Mesa, Tempe, Scottsdale, Queen Creek, San Tan Valley, and beyond. Contact us for a free assessment of your garage’s weather sealing and insulation.
Our Work
Steel Garage Services Include:
Bottom Seal Replacement
The bottom seal is the first line of defense against dust, water, and pests entering your garage. We replace worn, cracked, or missing bottom seals with heavy-duty rubber or vinyl strips that conform to your garage floor and create a tight barrier when the door is closed.
Side & Top Weatherstripping
Side and top seals close the gaps between your door and the frame. Arizona's heat and UV exposure cause these seals to dry out and crack over time. We replace them with UV-resistant weatherstripping that maintains flexibility and performance through years of temperature extremes.
Threshold Seal Installation
Threshold seals mount directly to your garage floor and create a raised lip that the door presses against when closed. They are especially effective for garages with uneven floors or gaps at the bottom of the door that standard bottom seals cannot fully close.
Between-Panel Seal Replacement
Flexible gaskets between each door panel prevent air and dust from infiltrating through the horizontal joints. These seals compress when the door is closed and expand when it opens. Replacing worn panel seals noticeably reduces the amount of dust that enters your garage.
Garage Wall & Ceiling Insulation
For garages used as workshops, gyms, or living spaces, we install rigid foam board or reflective barrier insulation on walls and ceilings. This creates a thermal envelope that keeps heat out in summer and warmth in during cooler months, improving comfort and reducing energy costs.
Air Leak Sealing & Diagnostics
We identify and seal air leaks around service doors, windows, electrical penetrations, and the junction between your garage and your home's living space. Caulk, spray foam, and weatherstripping close these gaps and prevent conditioned air from escaping into the garage.
Frequently Asked Questions
In Arizona's climate, rubber and vinyl seals typically last 3-5 years before they dry out and crack. We recommend inspecting seals annually and replacing them when they no longer form a tight seal against the floor and frame.
New bottom, side, and panel seals significantly reduce dust infiltration. While no seal system can block 100% of Arizona's fine desert dust, properly maintained seals make a dramatic difference in how clean your garage stays.
Yes. We offer retrofit insulation kits that attach to the inside of your existing door panels. While not as effective as factory-insulated doors, retrofit insulation provides a noticeable improvement in temperature control and noise reduction.
A complete weather seal replacement (bottom, sides, top, and panel seals) typically costs $200-$500 depending on door size and seal type. Threshold seals add $100-$250. We provide free estimates for all weather sealing services.
Yes. Sealing air gaps around your garage door reduces heat transfer between the garage and your home's living spaces. Combined with insulation, proper sealing can noticeably lower cooling costs during Arizona summers.
