Our People
Dedication and customer commitment is our core foundation. While others may promise – it’s in our Celtic DNA. From the warehouse to final delivery, our people are dedicated to exceeding your expectations.

Our Deliveries
Standing on a job site waiting for a delivery is painful, both mentally and financially – that’s why we go that extra mile, even if it means delivering twice a day or on weekends and holidays.

Our Fill Rates
Think of us like the ‘Google’ of Building Supplies. If it’s not in Celtic stock, our team will find a supplier or manufacturer somewhere that can get you what you need asap. If it’s out there – we’ll find it.

Our Location
Celtic’s dedicated fleet is primed and ready no matter where you are. Our new express vans allow for faster delivery for those last minute change orders!

Our Quality
We never sacrifice quality – period. Superior brands at the best price. To ensure the best pricing – Celtic is a member of several buying groups including LBM Avantage, one of the largest building buying co-ops in the northeast.

CSG Celtic Service Guarantee

Customer service is essential to our success.

We perpetually strive to provide our customers with a combination of value-added services coupled with superior products at competitive prices. Every member of our team is empowered to maximize the customer’s service experience on every transaction. That is the Celtic Service Guarantee.
