Reliable Dryer Vent

Had this company originally come in to clean our chimneys, in the new house we bought. The downstairs fireplace room would fill with dense smoke anytime we would light the upstairs fireplace. Company said we should install caps, so that's what we did for several hundreds of dollars. It did not solve the problem at all. Basement continued to fill with smoke any time we lit the upstairs fireplace. We called them back to have a look, in case they had misdiagnosed the problem. They said there's no crack in the chimney, so suggested putting fibre glass in one of the chimneys to see if that made the problem better. It did not. We called them back again. Guy came to remove the fibre glass from the chimney. They had no other solutions. When we called back the third time, the office had the audacity to tell us we should give the guy some cash for coming out there, because it was a long drive for him. Would never recommend this company, not only did they cost us a lot of money for what we've now found out can be done for much less (caps installation) but they also did not fix the problem we hired them too, and provided no alternate solutions. It's quite clear they are no experts in this field, and we regret hiring them.
