If they don't have it, you don't need it. Great, big, locally owned hardware stores with locations in Uxbridge and Northbridge. I've bought storm doors and had them installed, all kinds of tools and hardware. Great customer service. Need something? Get it here.

My father stopped in to buy a small item for his house. Not so important was the amount he spent in the store, but the fact that the next day an employee drove to his house across town to deliver his cane that he forgot in the store. It's so nice to have a company around that is willing to go out of their way to take care of their customers. Thank you to all who were involved in this kind gesture.

Dave & Loren are THE team to work with when building out a kitchen. From the start, both were great consultants as we strategized on what we needed in a kitchen, the flow of the kitchen in regards to locations of appliances, and helped us determine realistic options within our budget. Instagram and Pinterest offer lots of expensive inspiration that also can be unfriendly when it comes to cleaning.

Once we laid the foundation for our dream kitchen, we worked closely with Dave on design elements including our amazing island. He was so patient with us as we spent hours working through designs, cabinet colors and styles, picking out knobs, making sure every detail was perfect. We cannot thank them enough for all of the time and work spent with us to make our dream kitchen come to life. We would go back to them in a heartbeat if we had to do it again.
