A Message to Our Customers During the Covid-19 Outbreak & Adjusted Operating Hours

During these challenging times, The Big Tool Box and Highlands Garden Center continues to be committed to serving our community as we have for over 40 years.  We provide many items and services that are critical to people, especially when they are confined to their home. However, for the protection of our employees, we have shortened our hours to 8-5 Monday-Saturday and 9-5 on Sunday. All 4 of our divisions are open; The Big Tool Box, Highlands Garden Center, Rental and Repair, and our Lawn Sprinkler Center.

We appreciate that while your lives might have changed in many ways right now, you still need many things to keep your household running smoothly. We are well stocked to help you when things break or need replacing as they will continue to do.

To best facilitate your and our employees’ health safety, we have implemented the following procedures:

  1. Please respect 6’ social distancing with our employees when you shop with us and please do not enter our store if you are sick at all.
  2. We encourage you to shop online through Ace Hardware’s online shopping site . We have those links in yellow on almost every page. Just call when you are outside the store and we will bring it to your car.   Much of our ACE, Garden Center and Lawn Sprinkler Center inventory are available via this channel.  We do offer delivery through this channel as well.
  3. Please remember that you can shop outside for many things at both The Big Tool Box and Highlands Garden Center. These include mowers, fertilizer, mulch, soil, landscaping material, pots, and many early season plants. We will come outside to take payment if our staffing levels permit, or you can pay at the outside checkout window on the southwest corner of Highlands Garden Center or just inside in the Garden Center or Hardware store.
  4. EFFECTIVE IMMEDIATELY, Thursday, March 19, we will only accept credit cards or Apple Pay. We will not be accepting cash or checks due to the increased risk of spreading Covid-19 via those methods. We are constantly sanitizing the register areas as well as many other areas of our store.

The team at The Big Tool Box and Highlands Garden center looks forward to helping you through these troubling times with continued excellent, friendly service. We are trying to make that shopping experience as safe as possible too.
