18-Foot Garage Doors for Oversized 2-Car Garages
An 18-foot garage door gives your two-car garage the extra breathing room a standard 16-foot door can't. The additional width makes it easier to park two full-size trucks or SUVs side by side, open car doors without dings, and pull in without tight maneuvering. That's why 18-foot wide garage doors are a popular choice for large custom homes, new construction, and homeowners with oversized vehicles. At Discount Door, our family-owned team has more than 30 years of experience installing and servicing oversized double garage doors throughout Grand Rapids and West Michigan. Whether you're building a custom home with an 18x8 garage door or upgrading to an 18x10 garage door for a lifted truck, we'll help you choose a door that fits your space, your vehicles, and your home's style.
Popular 18-Foot Garage Door Sizes: 18x7, 18x8 & 18x10
The 18x7 garage door is a common upgrade for homeowners who want a wider two-car garage entry without changing the height of a standard 8-foot ceiling. The 18x8 garage door is one of the most popular sizes for custom homes and new construction, giving full-size pickups, SUVs, and vans with roof racks plenty of clearance. An 18x10 garage door is built for lifted trucks, work vehicles, and taller garages with car lifts or overhead storage. For a sectional overhead door, the rough opening typically matches the door size (for example, 18'0" wide by 8'0" tall for an 18x8 door), with side room on each side for the track and enough headroom above the opening for the springs and track. Because 18-foot doors are wider and heavier than standard double doors, they often require heavier springs, reinforcing struts, and sometimes high-lift track, so our team will measure your opening, headroom, and backroom before recommending the right door.
Insulated vs. Non-Insulated 18-Foot Garage Doors
An 18x7 garage door covers more than 125 square feet, making it one of the largest openings in your home and a major source of heat loss in an attached garage. That's why an 18-foot insulated garage door is a smart investment for Michigan homeowners. Insulated garage doors are rated by R-value, and a higher R-value means better resistance to cold winters and hot summers. A polystyrene or polyurethane insulated 18x8 or 18x10 garage door helps keep your garage comfortable, protects bonus rooms and living spaces above or beside the garage, and can help reduce energy costs throughout your home. Insulation also adds rigidity to a wide door, helping reduce flexing, dents, and noise during operation. Non-insulated 18-foot garage doors are a lower-cost option for detached garages and outbuildings, and we offer both so you can choose the right fit.
18-Foot Sectional, Glass & Roll-Up Garage Door Styles
Discount Door offers 18-foot wide garage doors in styles that complement large custom homes and oversized garages. Steel sectional overhead doors are the most popular choice, with raised panel, flush, and carriage house designs in a wide range of colors and realistic wood-look finishes. Modern full-view glass garage doors with aluminum or black frames make a bold statement on contemporary homes and fill your garage with natural light. For detached garages, shops, and pole barns, an 18-foot roll-up garage door coils above the opening to keep your ceiling clear for lifts and storage. Finish your door with window inserts, decorative hardware, and a powerful LiftMaster belt drive or wall-mount jackshaft opener built to handle the weight of an oversized door.
18-Foot Garage Door Prices & Installation Costs
The price of an 18-foot garage door depends on its height, style, material, and insulation level. A non-insulated 18x7 steel garage door is the most budget-friendly option, while insulated garage doors with higher R-values, custom carriage house designs, full-view glass doors, and taller 18x10 doors cost more. Other factors that affect 18-foot garage door installation cost include window inserts, decorative hardware, custom colors and wood-look finishes, heavier springs and reinforcing struts, wind load requirements, high-lift track, removal of your old door, and the type of opener you choose. Every project starts with a free, no-obligation quote so you know the full cost up front, and all of our installation work is backed by a one-year labor warranty.
18-Foot Garage Door Replacement Panels, Parts & Repair
Wide garage doors carry more weight and put more stress on springs, cables, and hardware, so regular service and quick repairs help your door last longer. Discount Door repairs 18x7, 18x8, and 18x10 garage doors and can source 18-foot garage door replacement panels, torsion springs, cables, rollers, hinges, reinforcing struts, and weather seals for most major brands. Our technicians handle broken springs, sagging or bowed sections, off-track doors, dented panels, and opener repair for homes throughout Grand Rapids and West Michigan. If your door is older or replacement panels for your model are no longer available, we'll give you an honest recommendation on repair versus replacement.
