If you consider using them... You can just as well give your money to a perfect stranger in the street!
They basically did nothing right. Our garage floor looked much better before they worked on it... Now it is a mess and they promise to fix it... But it has now been a few months and they are gone.
Our roof is leaking after they worked on it. It did not leak at all before. Now they requesting reports to proof it is them. When discussing the work before started, they promised if the roof starts leaking THEY WILL FIX IT, as they know they won't cause any issues. Do not trust them and do not use them. They have no work ethics and in your face.
