If you don't see your question below, call us — we answer the phone.
Do you install Unilock and bluestone?
Yes. Unilock, bluestone, cultured stone, and veneer. We match the material to the yard and the traffic.
Can you rebuild existing walls and steps?
Yes. Rebuild, recap, and new runs. We look at drainage first so the wall does not walk next winter.
Will this survive freeze-thaw?
That is the job. Base, pitch, and joints matter more than the pretty face. We build for Westchester winters.
Is veneer structural?
No. It is a face. The wall behind it has to be sound. We do not veneer over rot and call it a stone house.
