We here at Lochend have used Mason Quality Excavation for a few projects now and we can't recommend them highly enough.  The entire team is friendly and professional and they do an outstanding job in a stress-free way.

Caldwell & Highsted (and previously Caldwell Builders) have worked exclusively with Mason Quality Excavation whenever possible for the last fifteen years on many residential building projects. From large site dig-outs to awkward foundations under existing dwellings, Michael Mason and his team excel.  Their care, attention to detail, and can-do attitude, coupled with good communication means from scrape-off to back-fill to driveway contours, their job is completed and left ready for us to do our part.  We would unreservedly recommend Mason Quality Excavation for your future projects.
