What our customers have to say

Your project will be in good hands

We recently had the opportunity to work with Michael on our dining room renovation.  Michael is extremely detail-oriented and the pride he takes in his craftsmanship really shines.  The best surprise was how clean he keeps his work space.  Anyone who has lived through a renovation knows that is worth its weight in gold.

Renewed joy in owning our home

Our experience with Michael and his staff, as they spent many weeks building an extensive addition to our home, was exceptionally positive.  Michael demonstrated each day the skills that make a contractor a true professional: he was prompt, courteous, thorough, communicative and dedicated to the project.

Completed on time & within budget

Michael has completed two major projects for us. Both involved the preparation of detailed plans, budgets and final contracts covering extensive repairs and renovations.  His prices were competitive and, contrary to others who quoted, were supported by meticulous preparation and careful research of the specifics of each project.
