What Our Customers Are Saying

  • I have used Mason Construction for jobs, large and small, over the past 15 years and the results have been terrific.

    Bill C., Piedmont
  • I was the architect for several firestorm area homes, two of which were built by Mason. All field directives relating to refinement of the structure or the aesthetic were faithfully executed. Lowell Mason built several homes I designed in the early 70's including a custom home for my family.
