Umbrella were very professional. The replacement of sewage pipes was tricky for us in that the basement was already ostensibly "finished" - so we had been rather sad about the prospect of drilling up tiles and removing the flooring in the "newly renovated" house we had bought only the month before. Vlad's team did a great job installing the pipes through just a few strategically placed holes. They worked very hard and were finished quite quickly. (3 or 4 days). They also had to remove patio stone on the outside and this was replaced as well as we could have expected. We would certainly use them again.
