If you are in the market for cabinetry you need to go to Excelsior Kitchens and go see Karin K. She was great from start to finish. We visited Karin as we were completing a home renovation and needed some new kitchen and bath cabinetry. Karin was great to work with from the second we walked in. We was helpful, guided us to great decisions and worked within our budget. We would highly recommend her to anyone in the market for a new kitchen or bath. A huge thanks to Karin for all of her help!

I like these guys when I'm doing work in the Butler, West Milford, Bloomingdale, and Haskell towns. They're fair in terms of delivery and punctual, . The prices of lumber can't be helped. I recommend.

Thank you Karin for all your help. My cabinets look Fabulous! I love how they turned out. My kitchen may be small but you never made it feel like it was a waste of time. Doing this during Covid was a challenge but you made it stress free. Pictures don't do it justice. Thank you Tiziana

We used this lumber yard when replacing our deck ourselves in 2019. We were doing it on a very slim budget and price was a major factor and Excelsior came in under everywhere else we looked. We placed the order and we were warned by others that lumber yards will just dump the delivery in your driveway so we expected a mess but they came with everything packed nicely on a skid and they used a forklift to place it exactly where we asked which is a big deal because we have a small driveway.

The delivery person told us that if any pieces weren't to our liking, just to call them and they'd bring new ones. I think we had two pieces that weren't great but ended up being unused extras anyway. We get lots of compliments on our deck and I've recommended them to plenty of people. My brother and father have since used them for their deck renovations and were also very happy. I'd definitely use them again!
