Have you ever wondered what it takes to load a truck without wasting time or an inch of space? In this video our operations manager, Gene, gives an inside look at our warehouse.

Keeping orders moving and on time comes down to how the space is organized and the machines we use to move material through it.

Our Combilifts from Alta Equipment Company have been a perfect fit for us, as they can turn sideways, allowing us to set units closer together and use every part of our trucks when we load them.

Getting orders out on time matters to us and efficiencies like these are how we make it happen!

We had an incredible opportunity to collaborate with the Borough of Naugatuck and CCSU to supply materials for a dual timber bridge project for Baummer Pond Park here in town.

The CCSU Civil Engineering students build two bridges for the town using our lumber! The students did an amazing job, handling a ton of tasks to make this happen: conducting load calculations, creating an ADA-compliant structure, using southern yellow pine, getting proper permits, and everything else it takes to get something like this done.

Congratulations to the students, professors, and the town representatives, Sandra Lucas-Ribeiro & Jim Stewart, who made it happen!

Have a safe and happy 4th of July.

We're got Henry WeatherSmart housewrap in our warehouse, always in stock and ready to go. Here are some pictures of a project that we recently supplied materials for that used our house wrap!

Housewrap goes up between the framing and the siding. It's there to keep wind and rain from getting into your walls, while still letting moisture from inside the house escape. That balance is what keeps walls from rotting, getting moldy, or losing their insulation value over time.

If you're building, adding on, or re-siding, stop in and we'll help you out.
