"My single car garage door opener, which was a Wayne Dalton iDrive Torque Master, wasn't working properly and needed to be replaced.  I called JMK and they told me they could be out the next day to install a new Lift Master opener.  They showed up on time and started right to work.  They had to cut most of the old one down and put then new one in quickly.  They took all of the old opener with them and cleaned up after themselves.  It was done fast and looks great.

"I would highly recommend MR Garage Door! They contacted me right after I submitted the job & gave me a quote without trying to upsell. I was able to get them out when I wanted to have the garage springs repair done. They did a free tune up & realignment of my garage door. They explained to me some upgrades that we could do to the operation of our garage door, but there was no pressure. I was very happy with the workmanship & customer service of MR Garage Doors!"

FAQs for garage and garage door service projects in Walnut, CA

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.
