"Matvey/Groundworks resurfaced my garage floor in Bellingham. The team showed up early, prepared for a little rain, got to work and completed the job by about 4:00. pm. They were friendly, professional, fully independent, and did an excellent job cleaning up. The floor looks fantastic, with even disbursement of the flake and nice clean edges. Thanks guys!"
