I cannot say enough good things about Greg & Patryk and their team! One of my biggest hesitations about doing such a large project was knowing how hard it is to find a reliable contractor who would give us top quality work at a reasonable price. GS Construction exceeded our expectations in all areas! Our first floor remodel (kitchen renovation with wall removal, half bath remodel, new hardwood floors, updated laundry room) was completed right on schedule. Their attention to detail is amazing, often fixing or adjusting things that I didn't even notice. Their team was a pleasure to have in the house, all were so respectful and patient with our family as we mostly worked from home through the construction. The quality of work from their entire team (carpenters, plumbers, hvac, and painters) was well worth the price. We are beyond thrilled with our updated house! I would recommend GS in a heartbeat and will definitely call on them when it is time to update the rest of the house.
