Mike rebuilt our interlock landing and stairway and replaced peeling slate tiled stairs and landing with flagstone. He and his crew are top notch and great to deal with. They worked within our challenging budget and produced a product which appears to be 3 or 4 times the value. They were on site constantly until the job was completed and were on time and tidy. The quality of the work is outstanding and we would recommend Alpine to anyone, particularly for a larger scale project in Central or West Toronto, but call now and be nice - time is precious and chemistry is important.
