Update – WE ARE OPEN – but here’s what changes to expect until further notice.

It is with sad dismay we must make this announcement – the COVID – 19 Coronavirus is severely impacting and changing everybody’s lives. We’re here to assist, and we are open during normal business hours – however we must make changes to how we do business at 9 Brothers Building Supply until further notice.

Essentially, we will not be coming into contact with clients.

Our stores are open for business. We ask that we limit clients to 1 client per visit, while practicing social distancing. We also encourage using phone calls and our website to browse our products.

We encourage all of our clients and Masons, Landscapers, and Contractors to PHONE-IN their order, and utilize our website catalog for shopping.

We are still delivering.

All customer payments will be digital over the phone via Debit Card/Credit Card. Only known businesses will still be able to mail a check to us. New businesses must drop off or mail a check and it must clear before any goods are shipped or released for pickup. You can become a “known” business by filling out a credit application.

If you have any questions, please ask. We urge you to visit NY Governor Cuomo’s Issues Guidance on Essential Business List.
