One of Biddeford’s most beloved local businesses is also located in the epicenter of the so-called ‘Nightmare on Elm Street’, the six-month-long sewer upgrade project that has significantly interrupted traffic flow on Elm Street.
Dupuis Hardware is an old-fashioned hardware store, where knowledgeable employees can help you figure out what parts you need to repair a toilet or help you select the perfect grass seed for your lawn.
In an age of big-box stores, Dupuis Hardware remains as a community staple, and their customers are willing to put up with traffic in order to purchase a garden hose or get a new house key made.

“I think people really appreciate our friendly service,” said manager Stewart Dupuis. “We’re able to offer personalized service and can really focus on each customer’s particular needs.”
Dupuis Hardware has been in business since 1957, and they have a loyal and dedicated customer base.
But they have also been hit very hard by the ongoing construction project taking place just outside their front door.
Dupuis said the family-owned business had to let go of two employees because of plunging sales likely connected to the massive construction project.
“It’s certainly been challenging, that’s for sure,” Dupuis said. “We just have to keep pushing forward. You do what you gotta do to survive.”
Dupuis says his store is best known for its expert locksmith department that provides resources for people with missing keys or malfunctioning electronic key fobs and many other services.
“We just have to keep pushing

forward. You do what you

In addition to their professional locksmith services, customers can roam the store’s aisles and find everything from power tools to cleaning supplies; and from paint to gas grills.
If you have DIY project happening at home, a visit to Dupuis Hardware would be a good idea.
