No Trip Fees

Many garage door companies will advertise shockingly low prices without telling you about their hidden fees. Only until you receive your final bill, will you notice several added costs like trip fees or management costs. At Cornerstone Garage Door Specialist, we never charge additional fees especially for something as routine as driving to your home or business. As long as you are within the metro Atlanta area, expect one low, consistent price.

You’re the Boss

Let’s face it you’re the one calling the shots about your own home. Our team will give you a set of customized recommendations based on the size and specifications of your garage or carport, but our clients always have the final say. Our job is never finished until you are completely satisfied with your garage door. Our team is simply an expert opinion to help guide you through the process.

Upfront Pricing

With Cornerstone Garage Door Services, you should never expect the underhanded sales tactics that other contractors may use. We propose one simple, convenient price based on our original estimate. If our plan doesn’t match your budget, then we will continue working with you until it does. We never rely on commission and we don’t have a team of salespersons only a group of certified garage door professionals.

Certified and Insured Contractor

The entire Cornerstone Garage Door team is fully certified and insured, so you can have the peace of mind that industry experts are working on your home. Whenever you hire a garage door contractor, you should always make sure that the company is properly insured. If not, you might be held liable for any injuries or damages that occur on your property. Unlike those companies, our team is happy to review our comprehensive insurance coverage and the many certifications that make us the most trusted garage door company in Atlanta.

Free Estimates

Quality Guarantee

Homeowners seldom realize that the garage door is one of the biggest pieces of machinery in their home. If not correctly installed, then garage doors can be seriously dangerous. Our technicians have decades of combined experience and we guarantee safe, reliable garage door installation with only the most reputable products in overhead garage door technology.
