"New Marantec openers are much quieter and provide more light in the garage. I've been a customer of on Dulmaine & Sons since my house was built in 1988. I have no complaints - only praises. Will definitely call them for my future garage door needs."

"Great customer service! I inquired on their website and received a call back within a few hours. Chris was extremely honest and gave us a very fair estimate for the job. We signed off on the job the second week of March and the work was completed 2 weeks later! Hudson & Matt completed the project and were fantastic! Showed up right on time and explained everything they would be doing. They started our 2 car garage at 8am and were all cleaned up by 3:00pm! We are so happy with our new garage floor, it looks AWESOME! I would highly recommend GNU Garage!"

"Green Island Homes added a carport to our garage. They added value to the project at every step of the process. They improved the vague design ideas that we had. They implemented the ideas with quality materials and careful workmanship. They were great to have around: polite, neat, friendly! Great product and great value!"

Enclosing a carport essentially turns it into a garage. You’ll start by framing and finishing exterior walls, then add a garage door (averaging $1,200), windows, and wiring for lights or outlets.
Plan for site prep and, if needed, a thicker slab to handle the added weight. Once the walls are up, insulation, drywall, and exterior siding create a secure, weather-tight space that protects vehicles and gear year-round.
A well-built carport may not add a huge dollar figure to an appraisal, but it can boost buyer appeal. Covered parking protects vehicles and lawn equipment, sharpens curb appeal, and fills what might otherwise be an empty driveway space. If the carport matches your home’s style and stays in good repair, it can make the property more attractive and competitive when you decide to sell.
Most cities and counties require a building permit for a new carport. Fees range from $60 to $800, depending on local codes and the size of the structure. Getting the permit upfront ensures the carport meets zoning rules and HOA guidelines, protecting you from fines or expensive retrofits later. Check with your building department—or ask your contractor—before ordering materials or scheduling installation.
A poured concrete slab is the gold standard for carport foundations. Concrete delivers superior load-bearing strength, keeps posts level, and resists shifting in freeze-thaw conditions. While gravel, dirt, or permeable pavers cost less upfront, they can’t match concrete’s long-term stability, especially if you might convert the carport into a garage later. Investing in a slab now can save money and hassle down the road.
Pre-made kits start at $300 and bundle all the required parts—sometimes installation, too—making them the most budget-friendly option. Custom carports cost more ($12 to $40 per square foot plus labor) but let you match the design, size, and finishes to your home.
If price and quick setup top your list, go with a kit. If you have a tricky layout or want a seamless aesthetic, investing in a custom build is worth the premium.
