Frequently Asked Questions About Your Store

Is Express Delivery available at my store?

Select items can arrive at top speed with Express Delivery, a same-day service that delivers from your store to your doorstep. Orders must be placed by 4 p.m. local time to ensure delivery. Your order's eligibility depends on driver availability, local stock, and item size. Check if you can get Express Delivery when you set your local store in The Home Depot app or online. Qualifying products will show an Express Delivery tag in your cart and at checkout (excludes aerosols, custom mixed paint, and bulk orders). Additional delivery charges may apply for Express Delivery orders.

Is there a new Skelly in 2026?

Skelly fans will be happy to learn that our classic 12-foot Skelly with LCD eyes is back, but now there's an upgraded 12-foot app Skelly and a smaller 6.5-foot app-controlled Skelly for convenient scaring. When Halloween is over, keep your tall and terrifying decor ready for next year in our decor storage bag and 170-gallon storage tote designed just for these products. Remember to check out our new Halloween animatronics as well!

What fall house maintenance should I do?

Make certain your home is equipped for autumn cooling by repairing or replacing faulty parts of your hardscaping and home. If moisture gets in the crevices, you might be looking at trouble. Check brick and cinder blocks for cracks, and ensure indoor ceiling tiles are free from water damage. On the outside of your house, examine roof shingles or metal roofs for damage that could let water come in. Keep gutters functional and clear to prevent excess water from backing up into your home when storms arrive. Lastly, vinyl siding and chimney caps should be changed out if they're in poor condition.

Do you carry wardrobe moving boxes?

Make your move easier by picking up a mix of moving boxes. We've got the sizes you want, including specialty ones like wardrobe and TV boxes. Cushion your items with bubble cushion and moving blankets to ensure your belongings make it to your next location safely. Remember to check out our moving truck rentals if you need those, too.

Should I get a portable generator or an inverter generator?

Having a generator means you're prepared year-round for any circumstances Mother Nature throws at you. Whether dealing with severe thunderstorms or strong winds, a portable generator lets you enjoy power when the elements take it out. When browsing generators for sale, remember that portable generators cost less and generate more electricity than inverter generators, but they're heavier and louder. For safety purposes, always run your generators outside, away from windows and doors.

Why should I get a doorbell camera?

Enjoy peace of mind, safety, and privacy with a wired or wireless doorbell camera. No more peeking through an adjacent window when you can watch animal or human visitors in real time. Some doorbell cameras even let you speak to whoever is at the door via your phone, a useful interaction for delivery people or to scare off potential porch pirates. Most cameras integrate with your smart home app or hub to give you easy accessibility. Choose to save video clips for future reference and worry less with more control.

What's the project for the free Kids Workshop in November?

Head to our Kids Workshop to encourage future builders! Introduce your children to the joys of building with this wooden dump truck. Constructing a brightly colored toy is a great way to sharpen fine motor skills, creativity, and listening abilities. This cute kids' project is happening on November 7th, 2026, from 9–12 noon or while supplies last.

Did not realize getting quality pressure treated lumber would be impossible.
For the past year I have been shocked to learn my local suppliers Milford Lumber and Home Depot are unable to offer usable quality pressure treated lumber to its customers. Other than that Home Depot staff are some of the most friendly and professional I have worked with.

    No help at all?
    At nearly 70, I bought 800 lbs of concrete bags. When I asked for help loading a pallet into my truck I was treated with total contempt. After waiting a long time for a fork lift, I was told that I needed to rent the pallet. At that point I loaded the bags myself. I drove around back and saw a big stack of pallets. Never before have I heard of renting a lousy pallet. It was clear they were too lazy to help. Shameful...

        Always a great experience at the South Merrimack Home Depot
        I recently had another great experience at my home away from Home, the South Merrimack Home Depot. The folks on the floor are always hustling, very friendly and extremely helpful. It's refreshing in this day and age and big step up from the "other guys". Between these guys and the millions of DIY videos online, it is eye opening how much I can get done on my own what I used to pay someone else to do. This place is a no brainer. I should probably get my own parking space reserved since I am there so often.

            Love this Home Depot!
            The employees here are always so helpful and spend whatever time is necessary to help us find exactly what we’re looking for. It’s a big box store with a small town atmosphere!

              Terrible Customer Service
              Tried to buy a new washer and dryer. Order got completely messed up. Had to cancel. Used the HD credit card. They declined my follow up order, the one I was forced to place because of the errors in the first order. Drove to the store three different times. Called the credit card company. Was apologized to and assured all was well. Drove back to store and got declined. Used my own bank card for the order. After all that, they tell me the dryer vent to the side is not something they can help with, it’s my problem after they deliver it. Pathetic. Save yourself the hassle, go to Baron’s Major Brands, they will treat you right and get everything you need done. If you like the hassle, go with Home Depot.

                Self Check time is the best in the industry
                The self-checkout is fast and monitored properly to ensure the lines move at a fast pace, even when some have more difficulty than others.

                  Customer service
                  I purchased a snow blower on line it was ready for pick up when I got there . On the way out I noticed a defective rim on one of the wheels. It was small enough to easily go unnoticed , but I did see it . I brought it to the attention of the customer service rep. and the manager without hesitation got me another snow blower and removed the defective one from the sales floor. I am very happy with my purchase experience and wouldn’t hesitate to shop at that location again even though it is not the most convenient location to my home.
