"We wholly recommend Earthshare to anyone in the Upper Valley. Ethan and his subcontractors are timely, honest, flexible, and efficient. They gut-renovated two bathrooms for us, and updated almost all facets of our recently purchased house that had not been lived in for a decade.


It was a large project, and they completed it right on time (even with all the extra covid precautions we had to take). Their prices were reasonable and we were never surprised with surcharges. We love the work they did!"
