OUR STORY

In Water Mill Building Supply is a Hamptons based distributor of building materials to the trade including builders, contractors, architects, designers, and homeowners.  We are a major distributor of lumber, mouldings, trim, windows, doors, paints and stains, and tools.  New York City's oldest hardware store has a showroom located within our retail store that showcases kitchen and bath fixtures, lighting, lock hardware, architectural hardware, and decorative hardware.

1986, Dennis D'Angelo first opened Water Mill Lumber as a split Hardware Store / Tool Rental Center at its current location, 1110 Montauk Highway, Water Mill. Originally, lumber wasn't part of the product offering, but it was added a few years later. The Tool Rental Center moved to a separate location just down the road, and the store expanded as a lumber and building material and supplies provider for the Hamptons area.

In 2004, Dennis D'Angelo retired from the business, selling Water Mill Lumber to his sons, Steve and Paul D'Angelo. In 2008, Steve and Paul sold Water Mill Lumber to Trade Supply Group where it became what is now known as Water Mill Building Supply.

2009 brought the addition of a Water Mill showroom for Simon's Hardware and Bath, which quickly proved to be a success.  Their growing success also brought the addition of Water Mill's first ever outside sales team.

In 2010 and 2011, a big portion of the main store was renovated, including the Tool Department, Paint Department, Front End and Millwork Showroom.  Product selections and displays were improves, as well as our ability to serve our customers better.

In 2013, we expanded our outside sales team to improve service and communication with our customers.

We've recently had a big social and technological change - the launching of our mobile app, along with a new and improved website that allows you to place orders from your desktop or mobile device.  Today, Water Mill Building Supply works vigorously to complete the newly renovated main store and showroom.

Water Mill Building Supply offers only the highest quality products.  Our Engineered I-Beams are the leader in the industry.  We stock Boise BCI I-Beams and offer a full line of LVL's and Power Beams.  We also stock a complete line of Versa 0 Lam engineered framing lumber and a premium grade Douglas fir, the highest grade quality lumber available. This lumber is culled and separated from the rest of the mill and shipped directly to Water Mill Building Supply.  We offer the best and most detailed blueprint takeoff in the industry, and we supply all our builder's graphically engineered detailed floor by floor layouts with a complete cut list.
