Why Replace Your Garage Door

There are several reasons why homeowners choose to invest in a new garage door:

Types of Garage Doors

Several styles and materials are available when choosing a new garage door. Considerations include durability, insulation, noise, maintenance, cost, and aesthetics:


The most popular option, steel is affordable and very durable against dings, dents and rust. They require periodic repainting to maintain their appearance. Foam insulation sandwiched between two steel layers helps improve energy efficiency. Steel doors come in short 4-6 panel styles or long panel styles with over 10 panels.


Characterized by natural beauty, wood doors require regular maintenance including painting or staining every 2-3 years. Cedar and redwood are naturally rot-resistant, while oak and fir need additional treatments to prevent decay. Insulation helps reduce noise from rain and hail. Customizable with ornate hardware and designs.


Fiberglass offers the appearance of real wood with more durability and less maintenance. The fiberglass resists dents, cracking, and rust better than steel or wood. Efficient polyurethane insulation reduces noise. More expensive than steel but with a longer lifespan.


Vinyl is lightweight, flexible, and virtually maintenance-free. The rigid vinyl foam insulation reduces noise from the garage. Vinyl is prone to heat distortion and fading over long periods in direct sunlight. Durable yet flexible enough to withstand minor impacts.


Extremely strong yet lightweight, aluminum doors are rust-proof and resistant to salt corrosion. The higher initial cost is offset by being very low-maintenance. Without insulation, these doors can be noisy. Aluminum is easily dented so often not ideal for high traffic garages.

Calculating Costs

On average, expect to pay $1,500-$3,500 to replace an existing double-car garage door. However, many factors affect your total costs:

You can expect to pay around $2,000 for a basic 16′ x 7′ insulated steel door installed. Luxury wood doors with high-end openers and hardware can cost over $7,000.

Preparing for Installation

Proper preparation ensures your new garage door will operate safely and smoothly for years:

Measure the Opening

Use a steel tape measure to measure width at the top, middle, and bottom of the opening. For height, measure left, right, and center points from top to floor. Provide the exact measurements to the supplier to order the properly sized door.

Inspect the Existing Frame

Look for wood rot, cracks, or damage around the frame. Use a level to check for plumb and square. Repair any issues to ensure the new door will have a solid mounting surface. Professional shimming or framing may be needed.

Check the Ceiling Clearance

Standard headroom needed is 10″-12″ from the top of the door opening to the ceiling. Improve clearance by adjusting ceiling joists if space is tight. Many openers require up to 18″ of clearance.

Remove the Existing Door

Start by unplugging and disconnecting the automatic opener (if present) and manually locking the door in the fully open position using vice clamps. Then slowly un-tension the torsion springs using winding bars. Detach the spring hardware, cables, rollers and horizontal tracks. Finally remove the panels one by one.

Inspect and Repair the Tracks

Check tracks for dents, damage or misalignment. Use plumb bobs and levels to re-align tracks that are out of square. Blocks or shims can be used to adjust the angle as needed. Replace any heavily worn or bent horizontal tracks for smooth operation.

Update the Electrical

Have a licensed electrician inspect the outlet and wiring for safety and adequate capacity. Openers draw considerable power, so the outlet should be on a dedicated 15-20 amp circuit. Replace worn wire insulation and upgrade the circuit breaker as needed. Proper preparation up front will allow for a smooth installation process. Rushing in without assessing the full job can result in mistakes that affect garage door operation and lead to costly repairs down the road. Investing a bit more time in the prep work is well worth it.

Hiring Professional Installers

Installing a garage door involves heavy lifting, extensive hardware adjustments, and mechanical complexity. Unless you have prior experience, hiring professional garage door installers like Jennings Garage Door Service is highly recommended for safety and proper operation. Benefits of hiring pros include:

When getting quotes, look for insured technicians who are certified by the International Door Association (IDA). Members adhere to expertise, ethical business practices, and continuing education. Top providers also belong to the Institute of Door Dealer Education and Accreditation (IDEA). Ask for references and check reviews. Get a written estimate detailing all parts, advanced charges, labor, and warranty. Well established local companies with showrooms tend to provide quality installation and service. Schedule work 1-2 months in advance during peak seasons.

DIY Garage Door Installation

Ambitious DIYers can replace a garage door on their own with proper planning and caution. Having another strong person assist is ideal for lifting panels and adjusting hardware. Follow this process for DIY installation:

Prepare the Opening

Follow the preparation steps outlined earlier for measuring, inspection, removal, electrical upgrades, etc. Address any issues with the opening before moving forward.

Assemble & Install the Frame

Assemble the jambs, header, and support struts per the manufacturer directions. Set the full frame into place centered in the opening using shims and secure it with lag bolts and anchors through the jambs into the framing.

Add Tracks & Rollers

Mount the vertical tracks to the frame jambs and install the curved section overhead. With doors closed, fasten rollers into hinges on each panel. Lift panels and insert rollers into the track grooves. Leave doors closed.

Install the Springs

With doors fully closed, carefully fasten torsion springs to the roller shaft per spring instructions. Use winding bars to wind and tension each spring with exactly the number of turns specified. Adjust counterbalance as needed.

Adjustments & Finishing Touches

Test operation and make any necessary adjustments to the tracks, rollers, and springs until the door opens and closes smoothly, squares up in the opening, and maintains proper spring tension.

Install Accessories

Add automatic openers, any exterior keypads or remotes per separate instructions. Adjust downforce and safety sensor angles as needed for smooth operation. Seal the door perimeter with weatherstripping. With proper directions and safety gear, DIY installation can save on labor costs. Work slowly and get guidance any time you feel unsure. Calling in a pro such as Jennings Garage Door Service at least for the tricky spring work is wise for many. Either way, take your time with adjustments to ensure ideal door operation.

Maintenance & Repairs

Common repairs include:
