We hired Sam and his excellent team at Pieszak for a renovation that we were doing on our two upstairs bathrooms. We found out about them through Versatile Renovations, who I also recommend, and we couldn't be happier with how the entire project went. The final outcome is very beautifully built custom vanities, walk-in closet shelves, and a unique 'above john' storage on the wall for added storage.
Sam was very responsive in the planning stage to change requests on the design. I think I changed my mind at least 2-3 times before all the details were right, and each time he responded positively and quickly.
The installation was on time, very prompt, and very neat and tidy. This despite some material delays outside of his control (ask him about the Pietra panels, they are beautiful but I guess in high demand!).
I definitely recommend Pieszak, whether through a renovation, or just a cabinet project on its own!
