In order for my answer to be not regarded as any kind of "slander," I will do my best to simply describe what happened to us, trying to use as few emotional words as possible. But as a matter of fact I am quite angry, so my comment could tend to be somewhat "biased". Make your own judgment after reading this massage.
Judging from what happened to us, I must say they are not very professional. I would not recommend them to any of my friends.
We were buyers of a house and the sellers used SIRVA. When we entered the house for final walk-through, we got so mad at the dirtiness of the house. There were tracks, footprints, dirt, dust, etc. all over the floor. So many junks --- broken & discarded window blinds, empty boxes, etc. --- were left over. There were dusts in many of the closets and drawers. When we used Atlas Van Lines for ourselves to move from California to Ohio, they used blankets and tapes to cover the floor and stairs so that they would leave no scratches or tracks. It seemed that SIRVA did not cover the floor at all. Don't they think how new residents would feel when they come in?
So we immediately attempted to reach SIRVA to ask for re-cleaning. They did not responded to us for two days. So, surprisingly, the seller's agent (realtor) came to our house the next day of the escrow closing, and she cleaned the house on behalf of that company. Is this the right thing?
So I placed a complaint via SIRVA relocation website. I got an automated message from them, which said that I would receive response within 24 hours. They did not. They finally called me more than a week later. They said that we should have asked the cleaning credit before the closing of escrow, and since it is already past the escrow closing, there is nothing they can do for us. We did attempted to reach them, but they did not respond. How could we possibly discuss the issue before the closing of escrow when they never contact us?
Overall, I feel that I did not receive any respect as a customer from this company. To me it seems as if they are quite serious about their own reputation, but they do not show respect for persons who do not directly pay for them.
